An HD analog camera is a special type of analog, or CCTV, security camera that can record surveillance video in 720p high definition (HD).
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.
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
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.
