Choosing the best security camera system can be based on many factors. When it comes to the individual security cameras, the quality of images and video captured is largely dependent on the image sensor.
The image sensor (also known as the “eye”) determines the imaging capability and performance of your security camera. Their duty is to convert an optical image into an electrical signal, and is either a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) active pixel sensor.
To better understand which type of image sensor will work best for your security camera needs, we will take a look at the differences between CCD and CMOS.
What Is A CCD Image Sensor?
CCD’s receive light and convert it to electrons, then carry the electrons to a specific area across the chip to be processed. The conversion of analog light signals into digital pixels takes place in the chip without distortion. The special manufacturing process of CCD’s produces high-quality sensors in terms of fidelity and light sensitivity.
What Is A CMOS Image Sensor?
The CMOS sensor came from the MOS active pixel image sensor which emerged in the 1960s. Since then, its design and function has greatly improved, containing integrated circuitry and arrays of pixel sensors. Unlike the CCD, CMOS sensors process the elections at the same place that it receives the light, thus making it faster and smaller. The CMOS is able to do so because it has multiple transistors at each pixel, offering flexibility because each pixel is treated individually.
CCD vs. CMOS
Now that we have covered the basics, we can compare the strengths and weaknesses of CCD and CMOS cameras.
In these common applications, one camera outshines the other.

There’s something to be said about low-light security cameras. Because lighting conditions in different environments are not always ideal for surveillance, low-light security cameras enable us to capture respectable footage in these situations. And with new technology, the quality of low-light camera images has vastly improved.
But before you invest in low-light security cameras for your home or business, here are some important facts and tips to know to make the most of your security systems.
Here’s some important information in order to make the most of your security systems.
First and foremost, you should know the related terms you may come across:
All of these terms refer to the same classification of surveillance cameras. And while some of these terms are trademarked by manufacturers, the most commonly used terms for these cameras are “low-light” and “day/night.”
How It Works
Despite the sometimes confusing terminology, the basic components remain the same for all low-light cameras: a lens and sensor and some level of image processing. And to be clear, low-light cameras are different than thermal cameras (which track heat rather than motion or images) or cameras with IR illuminators.
A majority of low-light cameras use an IR cut filter, which is a mechanical filter that sits between the lens and the sensor (CMOS chip). The name is derived from its ability to “cut out” or filter out IR illumination during the day to improve color quality. At night, as available light diminishes, it slides out of the way to allow more light to get the sensor, thus improving low-light video quality. In order to help the video quality, it is also captured in black and white. In most cameras the filter is mechanically driven by an algorithm, however, some cameras allow manual control.
Because nearly all the cameras contain IR cut filters, it comes down to the lens and the processing to set these items apart from one another. The lens transmits light to the sensor and then the data on the sensor is processed by a processor. The variance among cameras is often in the optics. You want to be sure that both the lens and the sensor are of great quality, otherwise the potential for stellar images will be wasted.
Aside from the optics, processing is an important factor in determining the best low-light camera for you. Most manufacturers employ the same OEM processor yet make their own adjustments to them. The ability to control the tuning of an image is crucial as the tuning of an image during daylight will likely not hold up at night or in complete darkness.
Pay close attention to image toning, noise suppression, and the ability to maintain color and contrast in low light as these often differentiate one camera from another.
Typical IR cameras will capture images between 1 lux and 0.1 lux, however, the latest technologies can allow .01 lux to 0.00001 lux. This means that what would have been a completely black image a few years ago now looks like a near-daytime picture thanks to new low- and ultralow-light sensors.
While this achievement is impressive, in reality, there will rarely be any situations where there is complete darkness. Some ambient light will likely be present, whether it is from street lamps, the moon, or even the stars.
Spec Sheets Vs. Live Demo
As discussed, the impressive low-light sensitivity and lux will likely be included in the spec sheets, along with other important features. However, these spec sheets often represent technical specifications as opposed to actual performance.
Instead of simply relying on spec sheets, try to find a manufacturer or company that will provide you with a live demo and comparisons. This will give you a better idea of the low-light camera’s performance and whether or not it lives up to your requirements. In addition, third party reviews can give you more insight as well.
Just because a camera boasts a high megapixel count does not necessarily mean it will produce a better low-light image. With higher resolution and higher megapixels, each pixel becomes a smaller percentage of that sensor. For example, image the sensor has a fixed size, yet the resolution is doubled. The pixels are smaller, thus, the sensor for each pixel is also smaller, increasing the amount of sensitivity needed to maintain the same level of quality.
The speed of the lens is important and investing in a fast lens and better optics is crucial. The lens determines what information reaches the sensor, and, because of this, you get what you pay for when it comes to lenses and optics.
Positioning & Distance
Proper positioning of your security cameras is critical. Focus on what you want to capture and the level of detail you need when choosing the location of your cameras.
Position surveillance cameras so that the common range of motion is moving across the field of view rather than having common movement coming toward the camera. Also, avoid bright light pointing directly at the lens – this can cause flare or “fog” on the image.
Consider the field of view in terms of distance. The level of detail from the camera is highly dictated by how close the camera is and how much it’s zoomed in.
And when it comes to distance, you want the right combination of lens and camera that factors in the distance from the area you are trying to monitor. If you need to detect motion from long distances, your best bet would be to switch to thermal cameras. Activity will be detected, however, it will be harder to determine whether it is a person or an animal.

For the best home or business security, it’s important to choose the right CCTV security cameras. With the wide selection of security cameras to choose from, the task can seem daunting. To help ease some of the stress, here are a few things you should focus on when shopping for the perfect CCTV security system.
You always want to invest in good quality, but sometimes the ideal option falls a little bit out of your price range. That doesn’t mean you should just go the cheap route as this can end up costing you more in the long run. Remember, more often than not, you get what you pay for. Look for reputable security companies that offer a range of options from solid brand names (ex. Hikvision, Dahua, Axis) and pay attention to warranty offerings (reputable brands usually offer up to 3 years).
Consider what you need to record in order to narrow down which specific camera functions you require. From fixed position to a range of angles, and up to 360-degree range, there’s a security camera for that. Also consider the location of your camera and the environment as there are a variety of cameras that can accommodate as well.
Don’t understand the lens size of wide angle degree for CCTV cameras? We’ve got you covered. The rule of thumb is that for each millimeter of lens size that is how far away in meters the camera will be able to view its subject (focal length). The degree of the wide angle lens will determine the field of vision and shorten the focal length as the angle gets wider.
For example, let’s say you have a camera with 60-degree wide angle, 4mm lens. This camera will be able to effectively identify a human target at up to 4 meters, but will not have enough range to view a neighbor’s property to the left or right.
When it comes to storage and data, it will depend on the security camera and how long you will need to store your footage. IP cameras can connect to your network and enable real-time notifications as well as send data to your provider’s control center.
HD security cameras require better bandwidth and internet connection and may consume lots of data when accessed via mobile devices. They also require higher levels of storage to maintain their high resolution and quality.
The quality of images you need from your security cameras will often determine the type you choose. Analog cameras offer low-resolution images, and thus, decreased storage demands. HD cameras can record higher resolution images and are suitable for identifying numbers and characters. They also retain quality when digitally zoomed in. While basic analog cameras may be more affordable, if you’re looking for higher quality footage, you may want to opt for high definition or IP cameras instead.
If you have the best security cameras in poor locations and positions, what good are they really? Think about your property overall and begin by covering the perimeter. By securing the perimeter, you can get an early warning of any suspicious activity, allowing you to act accordingly and in a timely fashion. Also, having your security cameras in plain view but out of reach can be an effective deterrent.
Typically, CCTV surveillance cameras can record color during the day and revert to black and white recording at night. You can supplement your day and night cameras with motion sensor lights, which will allow for sufficient lighting for better images when motion is detected. Low light cameras are another option and may not need supplemental lighting.
When shopping for a CCTV system, you are not just buying cameras. Keep in mind the cost of other necessary items such as recorders, cables, connectors, an uninterrupted power supply, as well as the cost of labor, installation, and possible service provider fees.

As the New Year approaches, you may resolve to invest in a better business security camera system. Increasing your security measures can provide numerous benefits and will likely pay off in the long run. Here are a few ways a security system can help improve your business.
The presence of security cameras not only helps to deter burglars from targeting your business, but it can also bring peace of mind to your customers and employees.
There have been instances where employees fake an injury to claim worker’s comp, as well as customers who may make false claims against the business or employees. Security cameras can prevent these instances or provide evidence to refute these claims.
Security cameras and surveillance can positively influence behavior, resulting in employees complying with company policies.
You not only want to secure the inside of your business, but protecting the perimeter is just as important. Loitering may send the wrong message to your customers, and may negatively affect your business.
Aside from loitering, litter scattered around your business can damage the business reputation. You want to maintain an appealing look for your customers, and excessive litter can be detrimental.
Rather than having a security guard on the grounds, you can actively monitor your premises from within or remotely.
Keeping track of your business traffic can improve your business success. You can identify the busiest hours and adjust your staffing accordingly. It may also give you insight to the most efficient business hours for your location.
If you have more than one location to monitor, an advanced security system will allow you to connect the different security systems. That way, you may be able to remotely monitor all sites from one app or system.

Unfortunately, for many businesses, physical security is often overlooked. Some may have budget concerns while others may simply be too busy running their business. Sometimes it takes an actual incident for businesses to consider installing a security system.
Whatever the excuse, security should never be dismissed; it should be considered from the very beginning. As much as we would like to believe our chances of being targeted are slim, the truth is it happens more than we would like to admit. And thanks to advanced technology and increased demand, there are a variety of security solutions to suit different budgets and needs.
Here are some of the ways your business can benefit from a solid security system.
Deter Criminal Activity
This is obviously one of the most important reasons businesses look into security solutions. The presence of security cameras tends to discourage criminals for fear of being caught. In turn, they much prefer businesses which do not have proper surveillance systems in place.
In addition, security systems enable businesses to act quickly in notifying authorities when incidents do occur, helping to de-escalate the situation faster.
Protect Your Business Assets
Regardless of your company’s insurance policy, the loss of certain assets can still be devastating. For example, if your customers’ data is stolen, the repercussions could be extremely damaging and irreversible. Security systems come into play to secure assets which cannot be accounted for via insurance payouts.
Enhance Employee Safety
Employee safety is important, and security systems can help to protect and reassure your workers. For those who work late shifts, odd hours, or are often alone on the premises, security cameras can offer peace of mind. Should an accident or dangerous incident occur during this time, an advanced security system would be able to send out an alert and provide evidence as needed.
You will want to extend your security camera system to the employee parking lot as well, monitoring employees and they arrive and leave work, walking to and from their cars. Employees will also feel safer knowing their vehicles are under a watchful eye.
While you may think the costs are too high, security solutions can save you money in the long run. First, many insurance companies offer discounted premiums to companies that utilize security systems to deter criminal activity. Some insurance companies even go as far as helping small businesses by defraying the costs. Also, surveillance footage helps to speed up the claims process.
The surveillance footage may even be used to defend your company in the case of frivolous lawsuits. For example, if a customer spends time on your property then falsely claims they were injured, without security cameras, it is their word against yours. Video surveillance could prove who is liable and potentially save you from expensive lawsuits.
Enjoy Greater Peace Of Mind
Aside from the benefits outlined above, there is an intangible feeling of peace knowing that your business is secure. Most advanced systems now offer remote access around the clock, allowing you to check in from wherever you may be.
The next, very important step is to choose the right security system for you. There are numerous security solutions that offer different features and functions, so you should take the time to evaluate your needs and research different systems.

From simple cameras that captured video of the area in front of them to advanced cameras that offer exceptional features, our security camera systems have come a long way. The security industry has embraced the high-tech boom, offering sophisticated solutions and attracting more interest from consumers, thus driving home security system sales up over the years. We can only expect this to continue thanks to these security camera innovations, as well as those yet to come.
Video quality was once the defining factor of how advanced your camera was. Since high-definition and improved resolutions have taken care of that aspect, focus has now turned to the range and extent of camera views. Currently, most cameras can offer about 130-degree views, but 360-degree views are already being offered by newer security cameras.
This type of biometric technology enables your security cameras to distinguish strangers from members of the household. By doing so, home owners can be alerted to when members arrive home, as well as when unwelcome guests try to enter.
What was once a special feature has now become a standard function for security cameras. Night vision cameras can see almost as well as they can during the day and are often built to withstand extreme weather conditions, making them ideal for both indoor and outdoor use.
The security room, dedicated to numerous monitors and feeds, is becoming obsolete. Modern technology is now allowing security cameras to be integrated with smart phones, sending the live feed directly to these devices. Users are even able to change the angle of the camera from their device to investigate the area in question further.
Solar Power Integration
Solar-powered camera systems are much more energy efficient and can cut out the complications and vulnerabilities of hard-wired camera systems. A broader range of businesses are able to access security solutions thanks to solar-powered security cameras paired with wireless systems.
This feature is especially convenient for parents and pet owners to check in on their loved ones. Users are able to communicate through the camera to check in with kids or scold unruly pets. This feature can also be used to scare off intruders remotely, avoiding any immediate danger.
Voice commands and voice control has become a staple in our everyday lives, so bringing it into the security realm only makes sense. With voice control technology, you are able to manage your security systems completely hands-free. For example, you can turn on a camera, lock the house, or close the garage by simply activating voice command.

According to recent research, the video analytics market is expected to continue its growth in the coming years.
Here are some of the many benefits we can expect from video analytics software.
With video analytics software, security cameras can do much more. Modern IP network cameras often provide high quality video as well as embedded analytics. With smart business intelligence capabilities, which include queue monitoring and heat mapping, users gain valuable insights for personal safety, marketing, business management, and more. Other helpful analytics tools include people counting, motion detection, facial recognition and license plate readers.
Thanks to advancing technology, the processing power of security cameras and servers has greatly increased and continues to grow. As if that isn’t enough, prices are seemingly on the decline, making it easier for more users to reap the benefits. We can expect to see a market full of highly functional solutions at affordable prices in the near future.
Improved Decision -Making
As video surveillance use continues to soar, video analytics will help operators make informed decisions by delivering reliable information. As a result, the effectiveness and response time for video surveillance will improve.
You should know that most video analytics software for security cameras are either installed on the camera, the NVR, or offered as a third party software. While each will vary slightly, they will follow the same basic operation mode and will produce a beneficial end result.
How do you think video analytics will improve your business security solutions? If you are already using video analytics software, how has it helped? Share with us on Facebook, Google+, Twitter, LinkedIn, and Pinterest.

Video surveillance has often proven helpful in producing evidence after a crime has been committed, and plays a role in deterring some incidents. But unfortunately, it seems video surveillance is no longer enough. Threats of violence and attacks have become more prevalent, forcing us to increase our security measures.
Containing and preventing violence has become rather costly over the years. In fact, the economic costs for prevention and recovery reached a peak high at $52.9 billion in 2014. This cost is far greater than the cost of carrying out the acts.
A real time solution is necessary. This can start with technology that has the ability to detect weapons while assessing the level of threat in the process. While this advanced technology could save lives, it could also save us billions of dollars by stopping these incidents before they happen.
For example, the fiscal impact of the September 11th attacks was found to have cost $55 billion in physical damage, $123 billion in economic damage, along with other expenses such as developing the Homeland Security Department and funding the war. The tragedy of lives lost and money spent to repair damages shows us that a more proactive approach, rather than reactive measures, would prove to be more effective.
It is estimated that the United States spends about $100 billion a year on counter-terrorism measures. With proactive efforts, these reactive expenses could possibly go toward other areas that need attention and improvement.
Aside from anti-terrorism, surveillance technologies can benefit many industries. For example, big retailers are investing more into their security. Wal-Mart, for instance, is in the process of deploying drones to monitor warehouse inventory. It is advances like this that get us one step closer to embracing futuristic machines.

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.
