AHD Cameras

AHD CCTV cameras, also known as Analog HD CCTV cameras, have an availability to capturing high definition video surveillance at 720p and 1080p resolutions. AHD security cameras must be used with a AHD compatible DVR. CCTV Camera Pros supplies hybrid AHD / CCTV DVRs that work with both AHD and traditional analog CCTV cameras so that users can mix and match a combinations of both camera types.
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 big edge 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 RG59 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.

AHD vs 960H Video Resolution
The below images compare a video surveillance photo capture by a 960H CCTV camera with 720p and 1080p AHD CCTV cameras. The first two cameras where connected to an iDVR-E8 DVR to capture the images. The 1080p camera was connected to an iDVR-PRO AHD / HD-TVI / analog CCTV hybrid DVR. When we first wrote this article, 1080p AHD cameras were not yet available. iDVR-PRO recorders work with analog, 720p and 1080p cameras (AHD and HD-TVI).
The analog and 720p AHD camera were both displayed full screen at 720p resolution when the image was captured. The 1080p AHD camera was displayed at 1080p resolution. Please click on the images to see a full size view.

Analog 960h vs 720p AHD
Watch this video to see a comparison of analog CCTV standard definition vs HD video surveillance footage. This first video compares 960h analog CCTV resolution to a 720p AHD camera. Adjust the YouTube video player to 720p resolution and full screen to really compare and see the difference.

Analog 960h vs 1080p AHD Camera
This next video compares a 1080p AHD CCTV camera to an analog CCTV camera. Both cameras are connected to the same AHD DVR (it supports analog cameras too). The resolution of the analog camera is 960 x 480. Watch to see what a difference the higher resolution makes when it comes to digitally zooming in for facial recognition.
