In current devices, network surveillance cameras are undoubtedly the most popular. Whether in the long-term development or from the convenience of application, network monitoring equipment has already made a very good impression in people's minds. However, it may not be installed, and many users will have their own monitoring effects greatly reduced due to improper installation. So, what elements should we pay attention to when installing a network camera?
For surveillance cameras, the location is directly related to the imaging effect of the device. Therefore, many users regard the monitoring effect as the primary reference for monitoring the installation position of the camera. However, they ignore the very important point: surveillance cameras are not omnipotent, and they also have their own requirements in the choice of installation location.
The first is in the installation position, in order to enable the camera to avoid interference from the surrounding environment, to achieve a better picture and survival. When installing indoors, we should ensure that the height of the equipment is not less than 2.5 meters, and in the outdoor environment, we should also place the monitoring equipment at a height of more than 3 meters from the ground. Otherwise, whether it is from the perspective of camera self-protection or equipment monitoring, there will be many negative effects. Only after considering these most basic issues, the angle is the aspect we consider.
For network cameras, its line erection is obviously more abundant than traditional analog devices. However, no matter which transmission method is used, interference is one of the problems we have to pay attention to. Especially for the video signal transmitted by cable, the same direction transmission of the signal line and the high-power wire is undoubtedly a taboo in the wiring process, and it is not allowed to put the two in the same transmission line tube for the convenience of construction. Even if you are unable to separate the two even if you are restricted by the environment, you must ensure a separation distance of at least half a meter. Only such a plan can better avoid the impact of strong magnetic interference on video transmission.
For devices that use wireless signal transmission, there are fewer restrictions on the line. However, the camera itself must also avoid the surrounding sources of strong magnetic interference. At the same time, the camera is insulated from the ground.
In addition, we must also pay attention to avoiding the influence and obstacles of the line on the work of the gimbal.
In order to avoid reflections and shadows when using surveillance cameras at night, lighting equipment is usually required, and infrared lamps can be used instead of ordinary light bulbs. However, users must use black and white surveillance cameras and network surveillance video servers with infrared lighting because black and white surveillance cameras are more sensitive to infrared light, while color surveillance cameras are not capable of infrared.
Nowadays, many cameras have begun to adopt wide dynamic functions to enhance their imaging capabilities in backlighting environments. However, this does not mean that the camera can continue to work in a strong light environment. Because under the glare of the strong light, the direct glare easily causes the camera to locate the accurate image normally, which eventually causes the color filter on the sensor wafer to be permanently discolored, causing the camera to appear streak in the monitoring image. Therefore, if possible, we should make the camera in a "smooth" mode as much as possible, but in any case, we must avoid direct stimulation of the camera lens by glare for a long time.
Bandwidth limitations have long been one of the important reasons why network monitoring is difficult to scale. It is precisely because of this factor that the network users have long been divided into two levels - the ability to use self-built networks, and users without strength can only endure slow transmission, or find another way out. However, with the continuous improvement of compression technology and the optimization of the network environment. The living environment of network monitoring is also getting better and better.
However, if you want to achieve better network monitoring for general public network users, an advanced processing terminal is obviously indispensable. In terms of system performance, we should try to use the most advanced processing system such as linux or win7, and have advanced CPU, relatively large-capacity memory and graphics card, etc., so that our equipment can make the imaging effect more comprehensive. .
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 need to focus on and debug when setting up the equipment.
