What is AHD?
AHD (Analog High Definition Technology)
AHD technology can realize reliable transmission of ultra-long-distance (500 m) high-definition video signals on
analog transmission lines; it adopts advanced Y/C signal separation and analog filtering technology, which can
effectively reduce color noise in high frequency region and image reduction. better. Compared with the traditional
CVI signal, AHD's surveillance image quality has a qualitative leap and improvement, and the resolution can be equal
to the HD 1080P level.
At first AHD 1.0 technology allowed the use of 720P HD(high definition) Resolution cameras. The new AHD 2.0 version
introduced 1080P FHD(Full High Definition) resolution using traditional coaxial cable (RG59) at distances of up to 500m.
AHD VS other Cameras:
We usually call the video high definition with the physical resolution more than 720p, referred to as HD:
720p AHD/CVI/TVI=700TVL analog cameras (1280x720)
960P AHD/CVI/TVI =720p(1.0MP) Network cameras (1280*960)
1080P AHD/CVI/TVI=960P-1080P(1.3MP-2MP) Network cameras (1920x1080)
Traditional CVBS Analog NTSC Camera: 0.34 Mega Pixels (720×480)
Traditional CVBS Analog PAL Camera: 0.4 Mega Pixels (720×576)
Traditional CVBS Analog SECAM Camera: 0.4 Mega Pixels (720x576)
