The role of PoE technology in intelligent video surveillance system
Speaking of the intelligent video surveillance system, we can imagine, such as monitoring the picture more clear and smooth, more effective monitoring, can quickly retrieve the needed video and so on, these are the traditional video monitoring incomparable. Intelligent monitoring system is a very important equipment - transmission equipment, it is very important, it is not the lack of intelligent monitoring system, and its quality directly determines the quality of the entire monitoring system.
Normally, a network camera that works properly needs to connect a cable and a wire, and the following will cause the network monitoring camera to be unable to install:
1, the camera location without power supply.
2, the location of the camera installed power supply, but it is the lighting power supply can not provide all-weather.
The above network camera can not be installed, all occurred in the network camera power supply problems. In order for the network camera to be installed correctly, it is necessary to solve the power supply problem of the network camera. As we all know, in addition to the general network of video cameras need to transmit video signals through the network, but also must provide sufficient power to the weather. In the actual construction, often because of the inability to provide a stable power supply, and had to re design the location of the camera installation. Since it is not normal to provide electricity, you should consider using the cable to supply power to the camera, thus the PoE switch is generated, you can transmit data and power through the network cable at the same time.
The introduction of PoE network camera function greatly flexible power supply demand network camera, which can take place of electricity, can also through the network cable to take power, restricting the layout of the time from the traditional power line power point, can move and change the camera, in many areas have great advantage. With the rich and other PoE product manufacturers to invest heavily in the development of PoE technology, cultivate the market, PoE products in the performance of the gradual escalation of the gradual civilian in the price, the amount of PoE network camera multiplied. Security industry has gradually entered the era of no PoE HD Ethernet power supply PoE era".
The application of PoE technology makes the network camera has many advantages compared with the analog camera, such as eliminating the time and money to configure the power line, so that the cost of the whole system is obviously reduced. PoE does not need to change the Ethernet cable structure can operation, so the PoE system can save the cost of wiring installation is easy but also has the ability of remote power on and off, which solves the problem of power supply network camera required, will play a very important role in the development of future security monitoring in the field.
