[ Huaqiang Security Network News ] A complete POE system includes two parts: power supply equipment (PSE, PowerSourcing Equipment) and power receiving equipment (PD, PowerDevice). Therefore, the POE module is mainly composed of a POE power supply end and a POE power receiving end.
The POE power supply module, that is, the PSE power supply terminal, outputs a small voltage on the Ethernet RJ45 port until it detects that the cable terminal is connected to a power receiving device that supports the IEEE802.3af standard, and outputs a corresponding voltage according to the power receiving device. When multiple POE power supply modules are integrated into one power supply module box, it constitutes a POE power supply box, and the POE switch (integrated with multiple PSE power supply end devices) also has the function of a POE power supply box.
The POE power receiving module integrates the detection interface loop (IEEE802.3afinterface) and DC/DCConverter required for the power receiving device (PD) of the Ethernet power supply (POE) into a single package module, and supports the power identification circuit (classification, Ag8000/ 8100), allowing the central office power supply to deliver the appropriate power requirements to improve the overall system power consumption performance. As a POE power receiving module, it can provide power of no more than 13W for ordinary security products. Similarly, POE power-receiving modules can be integrated into general security products (such as network cameras) to form a stand-alone product POE network camera.
The POE network camera uses the POE module (including the POE power receiving module and the POE power supply module) to implement the power supply of the Ethernet. It has the function of the POE power receiving module, and uses the DC power provided by the power supply terminal device (PSE) to transmit through the twisted pair cable. To the POE network camera.
According to the video surveillance site environment, we can flexibly choose the power supply mode of the network camera: when the power is convenient and the cost is reasonable, the power cable can be directly installed. Instead, we can power the front-end network camera through the Ethernet twisted pair through the POE module. The POE power receiving module can be isolated independently or integrated into the network camera to form a POE network camera. The same POE power supply module can supply power to the front-end device separately. When the current end needs more power supply devices, the module can be inserted into the module box to form a POE power supply box to pass the Ethernet. The twisted pair is concentrated for power supply. The entire application reflects the advantages of POE modularity.
POE Modular Product Advantages: In addition to providing universal power support for connected devices from Ethernet cables, POE modules reduce investment costs, thereby reducing the total deployment cost of integrating power-on devices into a unified IP infrastructure. The POE module eliminates the need to install wall power connections for end devices, thereby reducing the cost of power outlets associated with supporting end devices. It also provides greater flexibility by installing network attached devices in locations where local AC power is more difficult to deploy. Because the POE power receiving module has the function of supporting the power identification circuit, when we use the UPS to supply power, the advantages of energy saving are more obvious.
The use of POE modules in life is still very common. The development of POE modules requires the development of various aspects of security manufacturers.
