Allthough, AHD Camera is not our key products line, we still want to tell what AHD CCTV is?
AHD CCTV is an?analog high definition closed-circuit television video surveillance standard that?uses coax cable to transmit HD video from security cameras to?DVRs. AHD supports 720p and 1080p HD video resolutions. You can find different styles of?AHD CCTV cameras here.
AHD CCTV cameras are connected to DVRs using the same type of coaxial cable as traditional analog CCTV cameras , typically RG59 or RG6 coax cable. One of the advantages of AHD over?HD-SDI cameras?(another HD over coax security camera standard), is that RG59 coax cable can be run long distances without video loss. So far in our experience, installers can reliably use RG69 coax cable up to a max distance of 800 feet for AHD cameras. ?AHD cameras can also use UTP cable with video baluns?to run cable up to?320 Meters / 960 feet with CAT5 cable.
At this moment, some similar HD Analog cameras appear in the market. Such as HD TVI solution and CVI solution. Also hybrid hd cctv camera, such as 4 in 1 and 5 in 1 security camera or digital video recorder.
