Five Requirements for Installing HD Network Cameras

With the continuous development of the network camera market, it has become a mainstream product in the surveillance industry. Many security monitoring projects use network HD cameras. Whether it is from the long-term development, or from the convenience of the application, network HD cameras are It has already laid a very good impression on people's hearts. However, there are still many customers who do not necessarily install, so that improper installation will greatly reduce the effectiveness of their network monitoring. So, in the installation of millions of HD network cameras, we must pay attention to those aspects?

Network camera location requirements

For surveillance cameras, the location of the camera is directly related to the imaging effect of the device. Therefore, many users regard the monitoring effect as the primary reference for monitoring camera installation locations. However, they have overlooked a very important point: the surveillance camera is not a panacea, and it also has its own requirements for the choice of installation location.

The first step is to achieve a better camera and survival effect in order to enable the network camera to avoid interference from the surrounding environment. When installing the indoor environment, we must ensure that the height of the equipment is not less than 2.5 meters. In the outdoor environment, we also need to place the monitoring equipment at a height of more than 3 meters from the ground. Otherwise, whether it is from the camera self-protection, or equipment monitoring point of view, will have a lot of negative effects. Only after taking into account these most basic issues, the angle is what we consider.

Network camera cabling requirements

For a network camera, its line layout is obviously more abundant than traditional analog devices. However, no matter what kind of transmission method is adopted, interference is one of the problems that we must pay attention to. Especially for wired transmission of video signals, the transmission of signal lines and high-power wires in the same direction is undoubtedly a taboo in the line-up process, and it is even more difficult to place the two in the same transmission line tube for the convenience of construction. Even if it is limited by the environment and it is impossible to separate the two, it is also necessary to ensure a separation distance of at least half a meter. Only such planning can better avoid the influence of strong magnetic interference on video transmission.

For devices using wireless signal transmission, there are fewer restrictions on the line. However, the camera must also avoid the strong magnetic interference sources around it. At the same time ensure the isolation of millions of HD network cameras from the ground. In addition, we must also pay attention to avoiding the impact and impediments to the work of the PTZ.

Lighting environment needs

When using a network surveillance camera at night, in order to avoid reflections and shadows, lighting equipment is usually required, and infrared light can be used instead of an ordinary light bulb. However, users must use black and white surveillance cameras and networks with infrared lighting to monitor the image server. Because black and white surveillance cameras are sensitive to infrared light, many cameras have begun to use wide dynamic capabilities to enhance their backlight environment. Under imaging capabilities. However, this does not mean that the camera can continue to work in a bright light environment. Because the strong light shines, direct light may cause the camera to be difficult to correctly position an accurate image, eventually causing permanent color decoloration of the color filter on the sensor wafer, so that the camera appears streaks in the monitoring image. Therefore, if possible, we will put the camera in a "smooth" mode as much as possible, but in any case, we must avoid the direct stimulation of the camera lens with strong light for a long time.

High-performance terminals are indispensable

All along, the limitation of bandwidth is one of the important reasons why network monitoring is difficult to expand. It is precisely because of this factor that the network users have long been divided by two levels - strong use of self-built networks, and the lack of power users either can only tolerate slow transmission, or to find another way out. However, with the continuous improvement of compression technology, as well as the optimization of the network environment. The living environment of millions of high-definition network cameras is also getting better.

However, if you want to achieve better public network users to complete network monitoring, an advanced processing terminal is obviously indispensable. In terms of system performance, we should try to use the most advanced processing systems such as linux or win7, and have advanced CPUs, relatively large-capacity memory and graphics cards, etc., in order to enable millions of high-definition network cameras to use their imaging effects. More comprehensive and clear.

In addition, if there are other auxiliary alarm facilities in our system, pay attention to their compatibility with the system, pay attention to the stability of the equipment itself in the current environment, and we also need to focus on and debug when setting up the equipment.

Network Camera Accessories Installation

In addition to the above-mentioned complete aspects, some network camera's auxiliary equipment installation specification is also a part of network engineering that must not be neglected during construction. For example, if the installation positions of the camera heads and racks are to meet the design requirements, the installation should be stable and firm and easy to operate and maintain. The distance between the back and side of the rack from the wall must meet the maintenance requirements; if necessary, we must install a protective cover or temperature control device on the network camera. For links with complex lines, we should also indicate the usefulness and characteristics of each line for future maintenance and grooming.
