What are HD analog cameras and DVRs?
An HD analog camera is a special type of analog, or CCTV, security camera that can record surveillance video in 720p high definition (HD). While previously only a feature available on newer IP cameras, these HD analog cameras are ideal for surveillance systems that need HD quality for video evidence but may not need more the more advanced features of IP video. To incorporate new HD analog cameras into an existing CCTV system, you will need to use an HD DVR capable of handling the HD video files.
How HD Analog Works
Analog CCTV technology has been around for more than thirty years in the security industry, giving users to security even when they aren't at the location. While the surveillance industry is moving toward IP technology, analog systems are still a popular choice.
Traditional analog cameras measure resolution by the number of horizontal lines, called TVL. A higher the number of lines in an image means better resolution (by contrast, IP cameras measure resolution in pixels).
The new HD analog technology allows you to record megapixel resolution video using analog components, resulting in 720p HD resolution from an analog system. These analog cameras continue to use standard coax cabling, DVRs, and can be easily mixed into your existing system. Please note, however, that you will need an HD DVR.
The benefits of HD analog over HD IP cameras include:
- Lower camera costs
- Simple installation, using the same process already in place for standard analog cameras
- Easy integration into an existing CCTV system
How HD Analog Cameras Can Help You
If you want to use your surveillance video as evidence of a crime, for facial recognition, to read license plates, or to help identify objects, high definition resolution is highly recommended. HD analog cameras installed near entrances and exits at face height can help you capture clear video of everyone coming into your home or business, in case you need to identify an individual.
HD resolution is also essential in capturing clear video of any crimes, attacks, vandalism, or other questionable behavior because it allows you to see exactly what happened.
As an affordable alternative to IP technology, HD analog cameras grant you access to the newest technology in the surveillance world while staying on budget, an important factor for small businesses.
HD analog cameras come in a wide range of styles, making them easy to fit into any location. Choose from indoor and outdoor cameras, along with bullet and dome form factors. A variety of leading manufacturers have HD analog cameras, including Verix.
