Problems that may arise with security camera systems are sometimes related to powering issues or even factory defects. However, more often than not, these problems are usually attributed to improper cabling and connections, which boils down to the installation.
Prior to security camera system installation, technicians must be mindful of the features, functions, and especially the limitations of the actual hardware. While all installations are different, an understanding of the specific system and the customer’s expectation is crucial for a quality job.
Here are some common installation problems you may come across along with helpful trouble shooting tips.
Rolling Lines On The Screen
Whether they are white or multi-colored, these rolling lines or ghosting over the camera’s video are often caused by video cables that run close to high-voltage power sources.
To prevent this, cameras should be tested at another location prior to installation in order to eliminate any hardware defects as a cause to any future issues. Also, keep wires away from sources that supply high-voltage electrical charges at any point of the run. Improperly grounded electrical circuits can also cause video disturbances, which is why high quality camera cables are crucial.
Infrared Glare/”White Out”
The most common causes of IR glare are reflective surfaces and large, lightly colored areas. “White out” (unrecognizable white silhouettes on screen) is often caused by objects that are too close to the camera. Also, if you install infrared security cameras under eaves, the beams of the IR LEDs may hit parts of the structure and bounce back, causing the reflection to blind the camera.
To combat these potential problems, install your cameras in areas clear of any objects that may cause glare or obstruct the camera’s view. Also, be sure that the user keeps these areas clear (at least three feet). You should also test daytime and low-light conditions before completing installation. Cameras with “Smart IRs” that have dynamic IR strengths can help to alleviate these problems as well and ensure high-quality night time images.
IR Cameras Unable To See In The Dark
In order to employ IR cameras properly, a surface is necessary for the IP light beams to bounce off. For example, when you point a flashlight into the night sky it remains dark because there is nothing allowing the light beams to bounce back.
Choose cameras that have sufficient IR distance capabilities. During installation, point the cameras at an angle facing a surface (ex. ground, wall) and test them under low-light conditions before proceeding.
Extreme Glare During Daylight
If your property has lots of glass doors and windows, you may have an issue with extreme glare. Glare from the sun does not mix well with security cameras, which means a special alternative is necessary.
In these situations, you want to invest in cameras with mechanical Wide Dynamic Range (WDR). These are designed to prevail in extreme lighting conditions. While “digital WDR” does it exist and can be helpful in these situations, it does not work as well as true, mechanical WDR.
Insufficient Power Causing Cameras To Drop Out
Without the proper power source, security cameras will not perform properly, causing them to drop out or lose power. While spec sheets may specify the camera’s power needs, they may not factor in the added power necessary for IR/low-light applications. For example, the system may work fine during the day, but drop out at night when the IR kicks in.
It is advised that you use a power supply which supports twice the voltage requirements of all your cameras combined.
When it comes to power, distance may play a role as well. Voltage drops can occur due to poor quality cables and long distances. To avoid this issue, AC voltage is recommended for runs greater than 250ft.
With great features and functions come limitations as well. For maximum coverage of your property, first map out your installation to identify areas that need surveillance. Based on the locations, you can determine which specific features you need for certain areas. For example, focal lengths and angles of view should be considered (longer lenses for closer view, shorter lenses for wide-angle shots). In general, license plate cameras should be installed no more than five feet from vehicles and valuable points of interest (such as cash registers, entrances and exits) should have a camera dedicated solely to monitoring that area.

When it comes to security, you want to deter intruders from targeting your property. Investing in advanced security and surveillance cameras with the latest technologies can be a smart approach, however, in order to be effective, they must be installed properly. Here are a few common mistakes to avoid when installing a security camera system on your property.
Mistake #1 – Hiding Your Cameras
The presence of security cameras can deter bad behavior, so why would you hide them? Making them visible from the street, yet out of reach, is a good idea. Keeping the cameras out of reach is important to prevent any tampering or vandalism that could compromise their performance. Burglars are always on the hunt for an easy target, and homes or businesses with security cameras create an extra obstacle.
Mistake #2 – Camera Positioning
The important places to monitor are rather obvious, but you must also take intermittent lighting and weather conditions into consideration. Things like direct sunlight can wash out your recordings, while rain or snow can build up on the lens, and windy days can make branches and leaves a problem. All of these can interfere with your recordings and possibly make your footage useless.
The best way to avoid these issues is to employ proper housing to protect and shade your cameras. Keep an eye on your feed to ensure that various weather conditions are not interrupting your surveillance.
Furthermore, if you’re using IP cameras, it is crucial that each camera location has strong and consistent Wi-Fi signal. Weak or spotty connection will impede your camera system’s performance.
Mistake #3 – Cheap Systems
Unfortunately, not all security cameras are equal. While there are many inexpensive cameras and systems that may seem appealing (especially to your wallet), you will likely run into performance issues. When shopping for security cameras, be sure to pay attention to features and specifications. Look into user feedback and reviews to ensure you are making a sound investment.
Mistake #4 – Passwords
With anything security related, we can’t stress enough how important strong passwords are. And always, always, ALWAYS change the default password. If someone gains unauthorized access to your surveillance feed, they can study the layout of your system and your daily routines, mapping out the best time to attack.
If you have an internet-connected system, it likely offers remote monitoring, thus you need a password to access it. Again, change your default password as soon as possible, and choose a strong, complex, and long password that you can remember.
Mistake #5 – DIY Installation
While it may seem more practical to set things up on your own, it might be better to leave it to the professionals. You don’t want to risk ruining your equipment because you installed it improperly. Trustworthy companies usually offer warranties, and will come back to fix any issues should they arise.

When you decide to install home security cameras, where you place your cameras and how you use your footage is important to consider. For maximum protection, it is recommended to monitor common areas as well as possible points of entrance. While home surveillance is not banned, there are a few things to keep in mind to avoid breaking the law.
Home Surveillance Concerns
Within your home, you do have the right to record without informing others, but there are very large exceptions to this rule. First, any area where a “reasonable expectation of privacy” is assumed is off limits. For example, if your home security cameras are monitoring your front yard and possibly the sidewalk and street, your expectation of privacy in these areas is low. On the other hand, bathrooms and bedrooms, where you may be in a state of undress, have a high expectation of privacy, and, thus, are prohibited.
Second, if your cameras enable audio recording, you may want to brush up on wiretapping laws. While these vary slightly from state to state, federal statutes allow audio recording so long as one of the two parties consents. This basically means that you, as the recorder, may know and give consent without informing the other party. However, some states, including California, require dual consent, meaning both parties must be aware and agree to be recorded.
In regards to recording burglars, any trespassers forfeit any expectation of privacy in your home. You may record the person, submit the footage to police, and use your video in court.
For cameras that run non-stop and record audio, you will want to warn any person that is allowed access to your home that these cameras are there and running, otherwise you may run the risk of breaking wiretapping laws. These people include family members, guests/visitors, delivery persons or installers.
The Consent Conundrum
You may now be wondering how you can lawfully gain dual consent. Will verbal consent or a surveillance sticker in the window suffice, or should you have every guest fill out a consent form upon entering? Unfortunately, consent for audio recordings must be given in written form. It is a common misconception that window decals or yard signs are sufficient means to gain consent, as it is expected for visitors to see and recognize them.
However, in a home setting, there may be an exception to the rule. With home cameras, it boils down to what you do, or intend to do, with your recordings. If you don’t do anything with the recording, it is likely that no one will know or care – no harm, no foul.
If you do something with the recording, things change. For example, say a celebrity is a guest in your home and now you have footage of this celebrity hanging out in your home. While selling this footage to a gossip magazine for profit may seem enticing, you will be breaking the law. First, consent was never given from this celebrity. Second, you cannot use a recording for commercial gain without the subject’s consent.
In regards to wiretapping, a possible solution is to simply turn off audio recording if your devices permit. However, why turn off a service that you have paid for? While thieves are usually fairly quiet while they work, using audio recording for eavesdropping may be beneficial (but puts forth yet another ethical dilemma).
Uses For Recordings
Let’s say you record someone in your home plotting a crime, or admitting to committing a crime. Most states allow you to use the recording to prevent a crime or prove that one was committed.
However, if the recording does not involve a crime and you decide to post it on YouTube or a social media site, you could be engaging in illegal activity. Using a recording for exploitive or commercial purposes (as in the previous celebrity example) may be misappropriation if not all parties consent. As a reminder, laws vary from state to state so please look into your own state’s laws.
Also, even within your own home, recording with the intention of blackmail is illegal.
Law enforcement has the right to ask for your home surveillance if they suspect illegal activity, and a warrant will likely be necessary. However, since most recordings are stored in the cloud, they may be able to go straight to the provider and obtain the footage, bypassing your permission to access.
What Should You Do?
To err on the side of caution, be sure that everyone entering your home is aware that the cameras are there, and avoid placing them in areas where privacy is expected. If you wish to withhold the information, so long as you do not do anything with the footage, you should be fine.
However, there are other reasons to be careful with the privacy of your security cameras. While you may not have the intention to do bad things, hackers may be able to access your cameras and broadcast your feed. To protect yourself and your guests, it is advised to take reasonable security precautions (ex. strong passwords, maintain security Wi-Fi network), and take the ethical high road when using new technology.
Aside from keeping your home safe from intruders, security cameras can serve many different purposes. Here are some clever and smart ways you can utilize your surveillance system.
Security Cameras & Floodlights
While there are security cameras with night vision and infrared LED lights, sometimes clarity and resolution is compromised in these settings. If you’re monitoring outdoors, consider installing floodlights to keep your surroundings illuminated. Floodlights with built-in motion sensors can help you save energy and startle whoever may be lurking in the dark. Consider installing these near doors or windows, patios, and backyards.
Wireless Security Cameras
Going wireless allows you to monitor places in your home that are off limits to your children, and can even allow you to keep an eye on your pets while you’re away. So long as there is Wi-Fi connection nearby, they cameras should be able to operate.
If you’re already using security cameras within your home, there’s no need to invest in a separate baby monitor. You can use a security camera, or a web cam, to monitor your toddlers while they sleep. Depending on your equipment, you may also be able to speak and soothe your child through the camera.
Peace Of Mind
If you have teens, you can make sure that they arrived home safely after school and are on their best behavior. If you have elderly parents that live on their own, remote access to their home security camera can alert you when something is wrong. Some systems even allow two-way audio so you can communicate with your family without picking up the phone.
There are devices on the market now that integrate a security camera with your doorbell. That way, whether you’re home or not, you can see who is at your door and communicate with visitors. This can be helpful if you have received a package, but no one is home to accept it. You can ask the delivery person to set it aside in an inconspicuous area.
You never know what you’ll catch with your security cameras. Whether it is the cause of a strange noise or an unfamiliar, suspicious-looking car from your outdoor cameras, or simply the culprit who is always leaving the food out, you can get to the bottom of some mysteries.
As one of the first mainstream home security cameras, nanny cams can be rather helpful. Whether you are wary of your nanny or other visitors in your home, you can use nanny cams to put your mind at ease. These cameras are often hidden in ordinary objects such as clocks, smoke alarms, teddy bears, etc., making them hard to distinguish.
Lastly, your security cameras can be incorporated into your overall smart home system. IFTTT (If This Then That) service is a free service that allows different smart home devices to connect and “talk” to each other. Some examples of what you can program include having your lights turn on whenever motion is detected in that room, or only having your cameras record when you are not at home.

People often take vacations over the summer, which makes it no surprise that July and August are the months with most break-ins. If you’re going away for a little vacation, use these tips to help keep your home and property safe.
Think Like A Burglar
Take a look at your home and think about the ways you would try to break in. These spots should be reinforced with extra security. You may also want to consider concealing your valuables. If burglars can see something they want through a window, they may be more likely to target that home.
Take pictures of your home and your belongings before you leave. In case a burglar does target your house, the photos can help to document any damage and help you create an inventory log with estimated values of your items. Both of these can be especially helpful for insurance purposes.
These will need to be adjusted if you have a house sitter or pet sitter coming and going, but, in general, you should:
To avoid returning to damaged property, turn off and unplug electronics, such as TVs, computers, or other devices, that could be damaged in the event of power surges. Depending on the length of your vacation, you may want to consider turning off the water and gas as well.
If possible, get your neighbors involved. Choose a trusted neighbor or two and politely ask them if they can keep an eye on things while you’re away, and offer to do that same if they leave. You can have the post office hold your mail, or have your neighbors pick it up, as well as any ads or flyers left on your door. You may also ask them to mow your lawn, trim plants, and set out trash cans, even if they are empty. This will help to keep up the charade that someone is occupying the home. Lastly, consider giving your most trusted a neighbor a spare key in case of emergencies.

Installing a surveillance system in your home or business can provide you with a sense of security. However, if you do not properly secure your system, cyber criminals can gain access to your video feeds.
Aside from an unnerving invasion of privacy, unauthorized access to your surveillance video can help criminals study the area, identify where important property is located, figure out traffic patterns, sabotage systems, deny access to feeds, and much more.
Because IP security camera systems connect to LAN networks, extra precautions are necessary to safeguard your system from attacks. Breaches are usually due to human error, negligence, and misconfigurations, and can often be prevented. The following are common vulnerabilities and ways to protect your surveillance system.
Default usernames and passwords are common with most IP based security cameras. They are used to set up your system and accounts for remote access. Too often, people fail to change these passwords, or choose simple passwords, making it easy for strangers to access feeds.
Be sure to set strong passwords, use good password management or user certificates in lieu of passwords. You may want to consider changing your password periodically as well.
Avoid enabling unused services as it can leave your system vulnerable to attacks. For example, cyber criminals could install malicious applications and scripts using file transfer protocol (FTP) or an app platform from an untrusted developer.
Minimize your risk by disabling any unused services and installing only trusted apps.
Sometimes organizations fail to define who has access to different aspects of the surveillance system, possibly leading to confusion and employees with unnecessary access. For example, it may be unclear as to who is responsible for reviewing security measures to ensure proper protocol is being followed.
For IT departments, it is recommended to only allow users access to the resources they need to perform their job.
Bugs and flaws in software codes can put your devices at risk. Luckily, you can do your part to prevent this.
Always keep your cameras, equipment, and software up-to-date with the latest firmware to ensure that bugs will not pose a threat. Vendors often post public common vulnerabilities and exposure reports which provide solutions for users.
Physical Installation Problems
Whether it is your cameras, wiring, or other infrastructure, poor installation can leave your system at risk.
Cameras should be installed out of reach to avoid any possible tampering or vandalism, but at a proper angle to view people and objects clearly.
Poor Physical Protection Of Equipment (Cabling, Servers, Gear)
If your cabling, server, or other surveillance equipment is not properly protected, your system is at risk for poor, intermittent performance. A small kink or damage to a cable can interfere with signal, causing disruption in your feed or even power failure.
Appropriate housing to protect your equipment from severe weather or extreme heat is available and is recommended for use if you are in an area susceptible to these conditions.
Routine maintenance is ever important to ensure that your system is and will continue to function properly.
A preventative maintenance program should include a checklist of issues to look for in order to avoid small issues that can turn into big problems (ex. damaged/loose cameras and equipment, exposed, loose, or damaged cabling, dirt/moisture on camera lenses). This will allow the owner to become accustomed to the system and more aware when something seems different or wrong (ex. possible signs of tampering).
Flaws In Standard Network Protocols
Most network surveillance systems use standard network protocols (ex. FTP, TCP/IP), however, weaknesses or flaws in these protocols can expose surveillance data to attacks.
For video streams sent over the network, the latest advanced encryption methods should be used.
Failure To Align Hardware/Software On The Network With IT Policy
If your hardware or software does not meet your IT organization’s network security policy, there will be security issues. For example, third-party software or apps are often poorly supported or lack security patches which make them vulnerable to security breaches. Thus, your IT department will not be happy.
Enforcing a strong IT policy is imperative for any business.
Security cameras are a great way to keep an eye on your property or business. You can use them to look after your loved ones, protect your inventory, or deter intruders all together. As appealing as security camera systems are, it is wise to know and understand your local surveillance laws.
Before you invest in your own security cameras, please review these general guidelines. Remember, these are not meant to apply to your specific situation. Instead, they are meant to give you a general idea of what is and is not allowed. If you have any further questions regarding filming restrictions and such, please contact a local attorney or research laws within your city and state.
Camera placement is important because you want to capture high traffic areas, such as entrances and back doors. If you direct your camera at an insignificant area, you will waste time and money while defeating the purpose of your security system.
Placement is also important because there are areas that are off limits, including restrooms, other people’s homes, dressing rooms and locker rooms. Basically anywhere that there is an expectation of privacy, or you are likely to be in a state of undress, is off limits.
If you are unsure whether or not you are violating someone’s right to privacy, err on the side of caution and always consult a lawyer.
If you own a retail business, you may worry that customers might be committing crimes in blind spots such as dressing rooms, locker rooms, or restrooms. While legally you cannot monitor these areas, you can monitor the entrances/exits. Be sure that when the door opens, your camera does not get any glimpse of what’s behind that door, otherwise you could get into trouble. If a person goes into a restroom or dressing room with some inventory, and then exits without it that is a suggestion of a crime.
Areas that are viewable to the public are generally legal to film. This is how Google is able to provide the 360-degree street view for Google Maps. However, it is ill-advised to point your security cameras at your neighbor’s home. Whatever situation that warranted your desire or need to film your neighbor’s home could become escalated. Whether you are the one filming or the one being filmed, you may want to first speak with your neighbor about camera placement.
With audio recording, Federal Law only requires one person to know about the recording taking place. State laws will provide different regulations. Remember that federal law creates a baseline for laws. That is, state laws cannot allow for any less than one informed party.
Audio is not allowed to be obtained through eavesdropping or remote recording. Because at least one of the parties must know of the recording, you are not permitted to record conversations you are not a part of since you do not count as one of the parties. Even if the conversation is taking place in a public area, the parties can still expect privacy which protects them from eavesdroppers. In the same vein, you cannot leave your unattended recorder somewhere and use the recordings as evidence.
The easiest way to get around audio recording rules is to make the party aware that they are being recorded. For example, often times when you call a customer service line, you will likely hear, “This call may be recorded…” Continuing the conversation after this notification is usually viewed as consent. Thus, once you have informed someone that a room is being monitored by audio surveillance, they have the choice to continue their conversation in that room or move the discussion to a different room.
You may also record a person so long as you don’t intend on using the recording for illegal acts. Because one party is aware of the recording, the act of recording is not illegal. However, if your recording contains private information that is covered by the common law privacy, you may get into some hot water. The private information could be things like medical history (ex. miscarriage, abortion) so be sure to understand what is and is not covered.
The Constitution & Surveillance
The Fourth Amendment protects citizens from “…unreasonable searches and seizures…” and details the rights of privacy. While you may think that some public security cameras would count as unreasonable, the case of Delaware v. Prouse will tell you otherwise. In this case, the Supreme Court stated that “people are not shorn of all Fourth Amendment protection when they step from their homes onto the public sidewalks”.
As far as the First Amendment goes, there has not been any critique on a camera’s existence suppressing behavior. In fact, in the Laird v. Tatum case, the court found that government surveillance of anti-war protesters did not hinder their freedom of expression. This can help security camera owners when there are accusations of civil liberty violations.
The First Amendment also gives you the right to document civil servants as they are performing their civic duties. The recordings are simply viewed as a way of exercising your rights. Officers may ask you to stop recording and ask for the evidence, however, you do not have to submit to their requests unless they have a warrant for your property.
The only instance in which you may be violating the law is if you are interfering with an investigation. This is often used to remove reporters from a crime scene, but your personal security camera should not interfere with the investigation. In fact, your video surveillance may be of use for the investigation.
If you ever wondered why most security cameras do not have microphones, it is because, in some cases, you may need dual consent to record audio. Violating dual consent is a felony. Your best bet is to get consent to be taped before recording, and then again as the first order of business when the recording begins. Off tape and on record consent will cover your bases if you are sued for violating wiretap laws. And although it is deemed “dual consent”, you must get the express consent of everyone being recorded.
The following states may have variations on the law and should be further researched: California, Connecticut, Florida, Hawaii, Illinois, Maryland, Massachusetts, Nevada, New Hampshire, Pennsylvania, and Washington.
The employer must have a legitimate reason for recording. The off limits areas include restrooms, locker rooms, and dressing rooms. There may also be restrictions in the break room. Again, you cannot record any place in which a person should expect privacy. However, anywhere that an employee interacts with a customer can be monitored. For example, the sales floor is fair game, but a personal office may not be. You will need to use your best judgment or consult an attorney. Disclosing the use of surveillance equipment to your workers will cover your bases for any illegal wiretapping issues.
The biggest restriction for recording employees is in regards to unions. An employer may not record union activities such as meetings or even discussions about union business. And surveillance cannot be used to intimidate current or prospective members of the union.
Evidence for Trial
When you submit any type of recording to a court of law, the evidence is put on trial. The validity and handling of this evidence is then scrutinized. You, as the recorder, must prove that the evidence was in no way doctored. You must go through the steps of how the footage was obtained (ex. how the video was recorded, where the camera was located, the quality of the camera at different times of day, how it was stored, etc.), and verify the whereabouts of the evidence as it was transported to court. When the footage is not in court, it must be securely stored. The integrity of your recording may be compromised if there is any data loss due to a power surge or data dump.

Wireless surveillance cameras are also known as IP (Internet Protocol) cameras. Aside from securing your property inside and out, they are also often used as baby monitors. When used as baby monitors, wireless IP security cameras are often equipped to pick up audio as well as video.
With these cameras, video footage is streamed to a secure online space and you may view what is happening on a computer or via a mobile app or device. To ensure the security of your live feed, these cameras should offer encryption for your streamed data along with a username and password protected hub or app for viewing your footage.
Does your system or equipment lack any of these? Do you want added security for your wireless surveillance cameras? Follow these tips to ensure the most secure experience.
Aside from securing your devices, the wireless network you connect to should also be secure. If you are using your home network, make sure your router is configured to use WPA2-based encryption. This will cover the connection between your cameras and router, while the stream’s encryption handles the rest.
You will want to steer clear of viewing your feed over open wireless networks. If you enter any usernames or passwords over these networks, they could potentially be “sniffed,” leaving you vulnerable. While these can be helpful when it comes to decreasing your mobile Internet charges, connecting to these open networks should not be done without the assistance of a VPN (Virtual Private Network).
Having your camera stream footage online 24/7 can be helpful, but it also leaves you more susceptible to privacy risks. Your ISP may be hesitant to support your excessive bandwidth needs for your IP security cameras, and any bugs in your system could threaten the security of your feed.
Online streaming should only be done when you are certain the stream is secure. For the remainder of the time, maintaining a closed and secure network for your IP cameras on a secure network should suffice.
Cameras usually have the ability to be password protected, but you must manually enable it. Once this feature is enabled, you MUST change the defaults. Since the default usernames and passwords for most cameras are easily to find, this is the easiest way hackers will be able to access your feed.
Aside from ensuring that your cameras are password protected, you should be sure that any device you use to access your feed is password protected as well. For example, if you access your feed from your mobile device, and somehow it gets lost or stolen, someone may have unauthorized access to your feed, as well as other personal information stored on your device.
With all this being said, the location and positioning of your cameras play an important role as well. In the worst case scenario, your feed gets broadcast to the public internet. Be sure that you position your cameras in areas in and around your property that you wouldn’t mind strangers seeing. For example, if you must install a camera in your bedroom, avoid pointing it at your bed or any area where you usually change.
You may also be worried about your webcams now, too. While threats may arise from time to time, there are ways to keep your webcam secure, such as disabling Flash, updating firmware, and using firewalls.
If you built a custom IP security camera using webcams, hacking threats should be minimal. You have likely used dedicated, reputable software and taken the time to properly configure and secure your system with a username and password.
To make sure that you keep your devices secure in the future as well, make sure that you keep any and all devices related to or connected to your system up to date. This includes your camera’s firmware, client software on your PC or mobile device, and more. These updates often contain patches for any new threats, and without the proper update, your system could be left vulnerable to an attack.

4K video is the latest in surveillance technology, delivering exceptional image quality and resolution. With four times the resolution as 1080p HD, 4K video blows high-definition video and older standard video formats out of the water. But, without careful planning, its effectiveness can go down the drain.
Switching to 4K video, or even HD cameras, is not as easy as simply buying the new cameras. While HD cameras require four times the storage and bandwidth as a legacy 480TVL camera, 4K cameras require four times the storage and bandwidth as an HD camera. Without the proper equipment to support such requirements, your new 4K system may not live up to your expectations.
Here are a few things to consider when you decide to adopt the new 4K technology.
Simply adding 4K cameras to your current system can quickly overwhelm it. On a normal data network, legacy 100Mbps is standard and is designed for computing data, not video streaming. Normal user data is considered “bursty” because user data is sent in bursts and remains low until the next burst. Memory buffers are built in so that if more data is received than can be processed, the data is stored until it can catch up.
Unfortunately, video streaming does not work like that. Video is sent in a steady stream, and if more data comes in than can be handled, the switch does not have a chance to catch up. This overload of data can result in dropped videos, or the switch may even lock up until it is rebooted.
Imagine a system that has 10 20-megapixel cameras sending at 3.5 fps, and requiring about 112Mbps of bandwidth. Hooking these cameras up to a 110Mbps switch will overload it, causing the system to malfunction. In the same vein, if you have two 110Mbps switches that have five 20-megapixel cameras each, they require about 56Mbps each and should work accordingly. However, if these switches connect back to a main switch that cannot handle the workload, you end up with the same problem as the first scenario.
When choosing a switch for your system, there are many things to consider aside from the port speed. Location is important, whether it be a core switch or a field switch. Also, you will want to pay attention to its switching capacity and buffer size, along with different features and support.
When it comes to server-based NVRs, again, if it is not designed to support and record at levels up to par with 4K or even HD cameras, you will come across performance issues. Things like bus speed and read-write speed on hard drives will affect how many devices you will need to support your cameras properly.
When planning for storage, you may want to consult with your IT department or an industry professional for guidance and advice. You must consider the number and type of cameras you need to support and how long you need the video to be retained. Proper storage abilities can make or break a quality surveillance system.
Power & Cooling
While often overlooked, power and cooling systems play a crucial role. Large scale video systems require a lot of equipment which need power for functioning, air conditioning to prevent overheating, and a UPS to safeguard from power outages or surges.

Often times, businesses don’t realize the importance of security camera systems until it’s too late. Rather than installing them prior to opening, they tend to invest in them after a burglary or incident occurs. This may happen because businesses believe that they cannot afford it, or they think the task is too overwhelming and complicated. Luckily, we’ve got some tips and tricks to help you choose the best security camera system for your business.
