Basic Description of HD-TVI, AHD, and IP Camera Systems 2

The first steps to buying a CCTV system can be difficult. Often times, it can be a whirlwind between HD-TVI, AHD, and IP (to name a few). While each type of camera has it’s pros and cons, its best to understand the key differences between each type.

 

 

HD-TVI

HD-TVI stands for high definition transport video interface. TVI cameras have the longest transmission without signal degradation across both RG59 and CAT5 cabling.  Coaxial cable (RG59) can reach 1600 feet where CAT5 can reach 700 feet. Video output quality is great with sharp images up to 1080p where true colors are visible. TVI allows the user to connect to any analog or HD-TVI camera, on any DVR channel, and is the only HD analog format to support IP cameras. Pricing on HD-TVI cameras is great given the outstanding picture quality. The only downside to having a TVI system is that they require a special DVR, but luckily, the DVR does support analog cameras.

AHD

AHD stands for analog high definition. These cameras can support RG59 and CAT5 cable, but the cables have a low transmission distance. Coaxial cable (RG59) can reach up to 1600 feet but CAT5 can only reach 492 feet. AHD provide good pictures but the images are not as sharp and colors are not as accurate as TVI. AHD cameras have won in the price category, where prices are almost as low as analog cameras.

 

 

IP

IP stands for internet protocol. IP cameras use network cable and provide a good solution for projects that require a large number of cameras. IP cameras have higher resolutions than standard analog cameras and provide sharp images at higher resolutions. IP cameras use Ethernet cable to transmit power, video and data. Some downsides of IP cameras is that they require a complex network infrastructure and are very pricey compared to TVI and AHD cameras.
