Network Eye AHD Concept
In general, AHD is the abbreviation of AmericanHeritageDictionary, which is the American traditional dictionary phonetic symbol. This interpretation is used more. From the perspective of security, AHD stands for AnalogHighDefinition.
AnalogHighDefinition means to simulate high resolution. Regarding HighDefinition, in simple terms, we usually refer to a format with a physical resolution of 720p or higher as HD, 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, interlaced scanning, 30 complete pictures per second; 720p means resolution is 1280×720, sequential progressive scanning, 60 complete pictures per second; 1080p means analysis Up to 1920×1080, it scans sequentially and presents 60 complete images per second.
AHD is based on the AHD protocol, which uses analog coaxial cable to transmit progressive video HD video.
Characteristics of network eye AHD
AHD is as simple and convenient to operate as traditional equipment. It can transmit up to 500 meters of high-definition lossless transmission with ordinary 75-3 coaxial lines, breaking the transmission limit of HD video transmission technology, enabling low cost, long distance and no Time-delayed, high-efficiency, anti-jamming and easy-to-implement megapixel HD video transmission.
Network eye AHD application range
AHD follows the approach and method of simulating SD transmission, which can reduce the complexity of construction deployment, reduce the cost of auxiliary materials and maintenance complexity, and the technical requirements for construction personnel. It is very suitable for the upgrade of the old system, and can easily upgrade the standard definition to high definition without changing the original system. In addition, the high-definition quality standard price, AHD has a very large development space in the civil and industrial markets.
