A brief analysis of the new era of analog high definition brought by AHD

Recently, AHDproducts in the high-definition field have mushroomed into the global market, attracting widespread attention from industry insiders. Our company has also recently launched AHDHD cameras andAHD DVRbackend. The following is a brief introduction to our customers what is AHD? What is unique about him?

1. Concept

In a general sense, AHD is the abbreviation of American Heritage Dictionary, which is the American Heritage Dictionary phonetic notation. To explain it from a security perspective,AHDrepresentsAnalog High Definition.

Analog High Definitionmeans analog high resolution. Regarding High Definition, to put it simply, we usually set the physical resolution to 720pThe above format is called high definition, referred to as HD. The vertical screen resolution it refers to is 1080i, 720p or 1080p. 1080i means that the resolution is 1920×1080, using interleaved scanning and rendering per second30full screen;720p means the resolution reaches 1280×720, using sequential scanning line by line, presenting 60 complete images;1080p means that the resolution is 1920×1080, using sequential scanning, rendering 60 complete screens

And AHD is based on theAHD protocol, which uses analog coaxial cables to transmit progressively scanned high-definition video.

2. Characteristics

AHDis as simple and convenient to operate as traditional equipment, and can be reached far away with ordinary75-5quasi-coaxial cable500Mi high-definition lossless transmission breaks through the transmission limits of high-definition video existing transmission technology and can achieve low-cost, long-distance, delay-free, high-efficiency, anti-interference and easy-to-implement megapixel-level high-definition video transmission.

3. Scope of application

AHD follows the approach and method of analog standard definition transmission, which can reduce the complexity of construction deployment, the cost of auxiliary materials and the complexity of maintenance, as well as the technical requirements for construction personnel. It is very suitable for upgrading old systems. It can easily upgrade standard definition to high definition without changing the original system. In addition, the high-definition quality and standard-definition price give AHD a very large space for development in both the civilian and industrial markets.

4. Development Prospects

In such an era of analog to digital high-definition surveillance, in such a period full of opportunities but also full of crises, the AHDproduct is high-definition market has injected a new vitality. This is undoubtedly another technological innovation in the high-definition market and will become a new trend in the security market.
