The advantage of AHD Camera

2023-03-23

AHD is Analog High Definition, which means analog high definition. Regarding High Definition, in simple terms, we usually call the format with a physical resolution above 720p as high definition, or HD for short. It refers to the vertical resolution of the picture is 1080i, 720p or 1080p.

1080i means that the resolution is 1920×1080, using interlaced scanning, and presents 30 complete pictures per second; 720p means that the resolution reaches 1280×720, adopts sequential progressive scanning, and presents 60 complete pictures per second; 1080p refers to the analysis The resolution is up to 1920×1080, using sequential scanning, presenting 60 complete pictures per second. AHD is based on the AHD protocol, using analog coaxial cables to transmit progressively scanned high-definition video.

AHD technology can realize 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 analog filtering technology, which can effectively reduce the color noise in the high frequency area, Image reproduction is better. Compared with traditional analog high-definition products, the monitoring image quality of AHD has a qualitative leap and improvement, and the highest definition can be equivalent to the full high-definition level of network high-definition 1080P.




The advantage of AHD Camera:

① Higher resolution: Advanced bright color separation, signal filtering, 3D noise reduction technology, higher image definition and better image restoration.

② Transmission distance: the coaxial transmission with ordinary 75-5 line can reach 500 meters.

③ Zero delay: the front-end data is not encoded and compressed to the back-end, full real-time, high-fidelity.

④ Good compatibility: Compatible with ordinary D1/960H, compatible with analog peripherals (including distributors, matrices, etc.).

⑤ Easy operation: Support OSD menu design, set your needs as you want.

⑥ High quality and low price: the price of ordinary simulation, high-definition quality products.

⑦ High integration: AHD front-end chip price, high-definition quality products.
