What is AHD?

AHD is short for Analog High Definition, so AHD camera is analog high-definition camera, transmission signal is the high-definition analog signal. Talking about high definition, in short, we usually call the video high definition with the physical resolution more than 720p, referred to as HD.


AHD technology can achieve the reliable transmission of ultra long distance (500 meters) high-definition video signal on the existing analog transmission line. It adopts advanced Y/C signal separation and simulation filtering technology, which can effectively reduce the color noise in high frequency area, image reducibility is better. Compared with the traditional high definition products, AHD camera image quality has a qualitative leap and upgrade, the highest clarity can be equivalent to the full network HD 1080 level.


AHD has 3 formats:

AHD08: Image definition between 960H and 720P, max to 800TVL

AHD10: Image definition of AHD is equals to 720P IP camera

AHD20: Image definition up to 1080P



AHD cameras advantages:

1. High resolution: Advanced signal filtering, 3D noise reduction, higher image resolution, better image reproduction.

2. Long range transmission distance: max. 500 meters over traditional 75-3 coaxial cable.

3. No video latency: Uncompressed video, real time transmitting

4. Better compatibility: Compatible with D1/960H products.

5. Easy to install: Support OSD menu, easy to operate and install

6. Low cost: Same price like traditional analog camera, but high definition image quality.

7. Open standard: AHD chip-set from third-party provider - Nextchip. Its standard is open for every security manufacturers.



AHD camera follows the method of simulating standard definition transmission, which can reduce the complexity of construction and deployment, reduce the cost of auxiliary materials and maintain complexity as well as technical requirements of construction personnel. It is extremely suitable for upgrading the old system, you can easily upgrade from standard definition to high definition without change the original system . In addition, high definition quality with standard defintion price, make the AHD camera has a very large development space both in the civilian and industrial market ( such as AHD car camera ).
