The term HD in 2010 went into the field of security monitoring. Faced with the previous video, the surveillance personnel had their eyes widened and they did not see the monitor. Now it has been well resolved!
The high-definition camcorder technology core high-definition camera surpasses the traditionally used analog camera in terms of intention. The high-definition surveillance cameras generally advertised on the market are generally megapixels. Generally, a monitor HD camera is judged based on the following points:
First, the camera's frame rate Second, color fidelity three, video aspect ratio and interlaced or progressive users in the purchase of surveillance cameras with high-definition, we must see the three key technologies on the specification. In terms of intent, high-definition cameras do not have a certain definition. Generally, image quality is not only defined as resolution. For example, a common 1280X720 30 frames per second surveillance camera can shoot 720P and 1920X1080 24 to 60 frames per second. 1080P. The higher the shooting frame rate of the surveillance camera, the faster the camera's operation speed.
Another important factor is the full-frame-rate video stream in order to capture fast-moving object activity in the field and to easily see and capture physical objects. For a high-definition camera, fidelity means sharpness.
Comprehensive development of HD security technology With the development of high-definition Puqing, more and more monitoring viewpoints can be delivered to surveillance storage devices through transmission devices. The front-end and back-end of the surveillance front-end in the face of high-definition Can we keep up with the demand for HD? The answer is yes: yes.
In the network monitoring of high-definition video data transmission, the limitations mainly come from the network bandwidth. Nowadays, many enterprises have adopted optical fiber as the transmission medium, thus breaking through the previous 100M bandwidth and can only carry about 5 high-definition images at the same time. When the visitor accesses the video in the video surveillance storage at the same time, the current situation of the network is very worry. Therefore, in the face of high-definition video surveillance images, only with fiber optic transmission can ensure smoothness.
For devices that store high-definition data sources, two methods are generally used: distributed local storage and storage arrays.
Usually, the local distributed storage means that the video images of each monitoring point are stored in the storage device respectively. For example, points A and B are divided. To see point A, the stored video needs to go to the A machine, and the B point to watch. It will go to B machine. Although inconvenient, it solved the HD transmission problem in a large program. For storage arrays, unified video management platforms are required to achieve unified storage and storage, and it is very convenient to perform storage access on a fiber-optic network.
Editor's note:
The current high-definition camera technology is getting mature, from the video conferencing, plant monitoring and security to the community are inseparable from its presence. For home security monitoring, it also occupies a very important position. It is believed that in the near future, high-definition will surely replace the analog surveillance camera as the leader of video surveillance.
