Choosing the right video surveillance system can be tough. With various technologies to consider, as well as your own personal requirements, there’s a lot to consider. For your convenience, here are some common terms and technologies to help you choose the right video surveillance system for you.
Because of our smart, HD televisions, we are all likely familiar with resolution as well as the units used to measure it (pixels). From its beginnings at 720 pixels to 1080p, we are now up to 4K and 5K resolution, with further advancements on the horizon.
The goal for resolution is to produce the clearest image for usability. This is defined by detection, recognition and identification and generally requires 80p around the face. Previously, pan, tilt, and zoom (PTZ) technology was employed to get a usable image. Now that camera resolution has greatly improved, less features and cameras are necessary to create high quality video surveillance.
Another term you are likely familiar with is frame rate. The minimum requirement for the HDTV standard is 30 frames per second (fps). A higher frame rate is ideal, as it will produce a smooth, clearer video, however, it may not be practical. A higher frame rate also requires more bandwidth and storage space as these tend to be larger files. In this case, you should evaluate and prioritize your needs to determine the frame rate for you.
Networks & Storage
Security cameras are a small percentage of the overall cost of a surveillance system (the cost for cables and storage quickly accumulates). With that in mind, you should figure out what you intend to do with the footage so you can make the best decision for networks and storage. For example, ask yourself if you would like to store the footage for later review, actively monitor your feed, or would you like to do both.
Once you determine your goals and how long you need to retain footage (if at all), you can figure out how much space is necessary before your data gets overwritten. Depending on your system and needs, you may be able to refine these details per camera/location as necessary.
Since higher frame rates lead to larger files and more required storage, video compression technology works to counter that. As it advances, it promises to reduce bandwidth and storage to provide more affordable and convenient options for consumers. Currently, H.264 and H.265 are the standard, depending on the cameras you choose.
As you may know, extreme light levels can interfere with a security camera’s ability to capture useful images. However, low light technologies have improved and can produce images in little to no light environments. For example, ‘lightfinder’ technology enables cameras to produce color video down to below one lux (one lux is a dark room, zero lux is an absence of light).
There’s also wide dynamic range, which allows cameras to capture usable images in varying lighting conditions. This feature adjusts and filters light to prevent washed out images, and is useful for hallways and doorways that can open into bright lights.
While most systems come equipped with software (which should be updated and patched regularly and as necessary), you can find and install software applications that deliver specialized features and functions that you desire. Just remember that the higher the cost of the system means more features, which can translate into more training required to learn how to use it.

It may be hard to believe, but the video camera has been around for more than 100 years (Fun fact: Thomas Edison helped develop it). A while after its inception, a handheld version was created, making cameras small enough to be out of sight. This technological advancement then spurred the beginning of video surveillance.
Before there were internet-connected cameras, there was Closed Circuit Television (CCTV). For a long time, CCTV was the security camera. CCTV security cameras were installed and directly connected to monitors. Then, you could either pay someone to monitor your camera feed or review recordings after the fact. Neither of these options was ideal – the former was costly, while the latter was not helpful in preventing incidents.
Luckily, improvements in technology have made it easier and more affordable to employ surveillance systems. We can now access live feeds from our security cameras remotely, which would not be possible without the advent of wireless security cameras and IP cameras. Here are some of the more prominent milestones of security cameras.
Streaming vs. Recording Cameras
As mentioned, most wireless security cameras these days are streaming live footage rather than using CCTV. It was about 20 years ago when IP cameras entered the market and changed the security industry. At this time, the video quality and technology were not yet up to par, but over time that changed. Continuing advancements brought forth IP cameras with high quality video along with the ability to stream online and control cameras remotely.
Video Content Analytics were first introduced about 10 years ago. The integration with security cameras enables multiple functions:
One of the challenges with security cameras was poor footage with dark, unfocused recordings. Fortunately, laser focusing was introduced and provides better picture and recording in limited lighting environments. Security cameras that have laser focusing deliver improved zoom and picture quality as this feature enables nearly immediate focusing via laser. Infrared technology also improves visibility in dark conditions (much like night-vision goggles).

We have seen smart technology take over many aspects of our lives. From smart phones to smart watches, smart technology continues to improve our day to day living and is spreading to our homes. A smart home incorporates smart technology into your house for added convenience and security among other benefits. Find out how you can start turning your house into a smart home this year.
This is the most common way that people ease into smart home technology. Smart lighting allows you to set a timer for your lights and control them through an app or possibly link them to your own voice assistant. But smart lighting is more than just convenience. Adjusting lighting when you are away from home helps to deter burglars by making it appear as if someone is home.
Security cameras also act as a deterrent, ensuring that your property is monitored and informing potential trespassers that they are being watched and recorded. Should they proceed anyway, you are equipped with video evidence of the burglary.
Smart surveillance cameras, often equipped with high definition technology, can be installed anywhere in or around your home. When motion is detected, these security cameras can automatically begin recording and send you an alert via smart phone or device when this happens. Some smart cameras even employ facial recognition to inform you when certain people have arrived home or an unknown visitor is present.
You also want to protect your home from damage, which is why smart leak detectors are growing in popularity. These alert you when water is detected where it shouldn’t be, preventing costly water damage and enabling you to address broken appliances or burst pipes immediately. Considering the cost of damages that you may be preventing, investing in these leak detectors is a smart choice.
While not necessary, smart fridges offer a range of innovative and convenient features:
Much like a smart camera, a smart doorbell allows you to see who is at your door via your smart phone, with additional security features:
