At present, security monitoring equipment is widely used in our life. Both units and individuals, after the great convenience brought by the security monitoring system, have also moved the idea of installing surveillance cameras. Therefore, video surveillance equipment has gradually become a frequent visitor around us.

Among the current devices, network surveillance cameras are undoubtedly the most popular among users. Whether from the long-term development or from the convenience of application, network monitoring equipment has laid a very good impression in people's hearts. However, installation is a technical activity, and many users have greatly reduced their monitoring effect due to improper installation. So, what should we pay attention to in the installation of webcam?

Camera location requirements
For the surveillance camera, the position is directly related to the imaging effect of the equipment. Therefore, many users regard the monitoring effect as the primary reference for the installation position of the monitoring camera. However, they ignore a very important point: the surveillance camera is not omnipotent. It also has its own requirements in the selection of installation position.

First, in the installation position, in order to avoid the interference of the surrounding environment and achieve better photographing and storage effects. When installing in the indoor environment, we should try our best to 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 3.5 meters from the ground. Otherwise, whether from the perspective of camera self-protection or equipment monitoring, it will produce many negative effects. Only after considering these most basic problems, the angle is the aspect we consider.

Installation of network surveillance camera: wiring and lighting requirements
Camera wiring requirements
For the network camera, its line erection mode is obviously richer than the traditional analog equipment. However, no matter which transmission mode is adopted, interference is one of the problems we have to pay attention to. Especially for the video signal transmitted by wire, the same direction transmission of signal line and high-power line is undoubtedly a big taboo in the stringing process, and they cannot be placed in the same transmission line pipe for the convenience of construction. Even if the two cannot be separated due to environmental constraints, it is necessary to ensure an interval of at least half a meter. Only such a plan can better avoid the impact of strong magnetic interference on video transmission.

For the equipment using wireless signal transmission, although there are fewer restrictions on the line. However, the camera itself should also avoid the surrounding strong magnetic interference sources. At the same time, ensure the insulation and isolation between the camera and the ground.

In addition, we should also pay attention to avoid the influence and obstruction of the line to the PTZ work.

Requirements for lighting environment
When using a surveillance camera, in order to avoid reflection and shadow, lighting equipment is usually required. Infrared lighting can be used instead of ordinary bulbs. However, users must use black-and-white surveillance cameras and network surveillance image servers with infrared lighting devices, because black-and-white surveillance cameras are sensitive to infrared, while color surveillance cameras cannot play the infrared function.

Nowadays, many cameras have begun to adopt wide dynamic function to improve their imaging ability in backlight environment. However, this does not mean that the camera can continue to complete its work in a strong light environment. Because under the illumination of strong light, the direct strong light is easy to make it difficult for the camera to locate the accurate image normally, and finally cause the permanent decolorization of the color filter on the sensor chip, resulting in stripes in the monitoring image of the camera. Therefore, if possible, we should try our best to make the camera in a "smooth" mode, but in any case, we should avoid the direct stimulation of strong light to the camera lens for a long time.

Installation of network surveillance camera: terminal performance and accessories
High performance terminals are indispensable

For a long time, 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 network users have been divided into two levels for a long time. Those with strength adopt self built networks, while those without strength can only endure slow transmission or find another way out. However, with the continuous improvement of compression technology and the optimization of network environment. The living environment of network monitoring is also getting better day by day.

However, if you want to realize that ordinary public network users can better 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 CPU, relatively large capacity memory and graphics card, so that our equipment can give full play to the imaging effect.

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

High quality network monitoring is inseparable from advanced terminals

In addition to some complete aspects mentioned above, the installation specifications for auxiliary equipment of some cameras are also links that we should not ignore in construction. For example, the installation position of camera pan tilt, rack and other equipment shall meet the design requirements, and the installation shall be stable and firm, easy for operation and maintenance. The distance from the back and side of the rack to the wall shall meet the maintenance requirements; When necessary, we need to install a protective cover or temperature control device for the camera. For links connected by complex lines, we should also indicate the use and characteristics of each line for future maintenance and sorting.

The above mentioned is the key link we need to pay attention to when setting up a simple network monitoring system. Compared with some complex large-scale monitoring systems, these aspects are obviously more simple and intuitive. However, from a critical point of view, these can be said to be the lifeblood links affecting the quality of camera work, which can never be ignored. Only when we grasp these important but easily overlooked elements mentioned above can we enjoy more efficient and convenient network monitoring effect.

Many factors should be considered in the process of network camera installation. The selection of location is the primary factor. It is at least three and a half meters away from the ground to avoid too many monitoring dead corners. We should also pay attention to many points in wiring and lighting. Only by fully considering these factors can the surveillance camera give full play to the monitoring effect.
