What is AHD onboard monitor? Yuhong pioneered the AHD HD car monitor, which can directly AHD million HD camera signal, enter a new high-definition mode, color, clarity into a new stage, Yu Hong more secure, has been imitated never been exceeded. 
First, concept
In a general sense, AHD is the abbreviation of American Heritage Dictionary, which is the American traditional dictionary phonetic symbol. This definition is used more often. From the perspective of security, AHD represents the Analog High Definition.
Analog High Definition means analog high resolution. With regard to the High Definition, simply speaking, we usually refer to a format with a physical resolution of 720p or more as HD, or HD for short. The vertical resolution of the screen refers to 1080i, 720p, or 1080p. 1080i refers to a resolution of 1920×1080, adopts interlaced scanning and presents 30 full frames per second; 720p refers to a resolution of 1280×720, adopts sequential progressive scanning, and presents 60 full frames per second; 1080p refers to resolution. Achieves 1920×1080, adopts sequential scanning and presents 60 full frames per second.
The AHD is based on the AHD protocol and uses analog coaxial cable to transmit progressively scanned high-definition video.
Second, characteristics
AHD technology can realize reliable transmission of high-definition video signals over distances (up to 500 meters) over existing analog transmission lines; it adopts advanced Y/C signal separation and analog filtering technologies, which can effectively reduce high-frequency areas. Color noise, better image reproduction. Compared with traditional analog HD products, AHD's surveillance image quality has a qualitative leap and improvement. The highest definition can be equal to the full HD level of network HD 1080P.
AHD breaks through the transmission limits of existing transmission technologies for high-definition video, enabling low-cost, long-distance, no-delay, high-efficiency, anti-jamming, and easy-to-implement megapixel HD video transmission.
Third, the scope of application
AHD follows the methods and methods of analog 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. It can easily upgrade SD to HD without changing the original system. In addition, the high-definition standard definition price makes AHD have a very large space for development in both the civilian and industrial markets.
Fourth, AHD application in the car
The continuous increase in the number of cars in recent years has led to a large demand for automotive electronics. On-vehicle monitoring and on-board video imaging have been widely used as vehicles for solving visual blind spots and job storage, and have become a necessity for car owners. After nearly a decade The development of ordinary analog video display has been unable to meet the needs of some high-end users, thus the need for updated car HD.
Fifth, the birth of AHD-board display and application <br> <br> Yu Hong Electronics has been focused on automotive electronics industry, through years of research and market a number of products in the industry's first, has been imitated, never surpassed, Research, take the lead in the industry, the first to develop the AHD on-board display for vehicles, to break the industry gap, AHD on-board monitor can be directly connected to AHD million high-definition camera (realize the vehicle in-car monitor can not directly million HD camera defects), Realize the real car HD display. AHD's image quality has a qualitative leap and increase.
