720p AHD camera

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. 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 balloons to run cable up to 320 Meters / 960 feet with CAT5 cable.

Analog HD-over-coaxial technologies are cheaper and able to deliver so-called “720p / 1080p” HD video, but IP camera system is future proof. Unless you want to upgrade existing analog system because coaxial cables are not easy to replace, HD-over-coaxial products can be good choices. So, 720p AHD/CVI/TVI vs. 720p IP camera, which is better?  The answer is 720p IP camera is better. From end-user’s report, the 720p AHD image resolution is poorer than 720p IP camera, but 960P (1.3 megapixel resolution) image quality is equal to 720p images from IP cameras.

AHD CCTV stands for analog high definition it is a new video standard for CCTV cameras and DVRs. This article compares 960H CCTV vs 720p AHD CCTV camera
