POE (Ethernet's power) technology can be transmitted by some POE Switch, POE SWITCH, POE Injector & Poe Splitter, etc. with some POE Injector & Poe Splitter, and so on. The unused position of the POE injector is there, and it can be accessible to installing equipment in the difficulty of reaching, which has a small impact on the existing structure and budget. Want to learn more deeply about the POE injector? This article will help you find out "What is POE fuel injector?" How to use the power of the Ethernet syringe in the application and solve your problem in the final common questions.
What is a POE injector?
PoE fuel injectors, also known as medium or POE adapters, can be used to power the POOE compatible switch and POE device by power supply POE device on a single Ethernet cable.
The benefits of the POE adapter:
Easy to install: Just connect the POE injector to the POE endpoint and connect the POE syringe to the Ethernet switch to provide data and power.
Flexible network extension: POE fuel injector adds the POE function to the non -POE Ethernet switch. The switch expands the network connection distance and provides a combination of power and data on the Ethernet cable to make the device end to get a better one to get better. connect.
Minimum investment budget: Using the existing Ethernet equipment and wiring infrastructure, it will minimize related costs in the POE fuel jet solution.
How does the POE injector work work?
The Ethernet switch or other devices does not have a POE function, but you need to support PDS (POE IP camera, POE wireless access point (WAP), POE lighting, etc.). POE fuel injector can help transmit power and data to these aspects. Up to 100 meters. Generally, the POE fuel injector converts the AC current into a DC current, so it can become a power supplier of the low -voltage POE device.
POE injector type
Active and passive POE injector
POE injector follows the POE standard IEEE802.3AF, IEEE802.3AT or IEEE802.3BT -Use Active POE. 802.3AF/AT/BT is a handshake between the power supply sending and receiving the POE device. If the receiving device cannot provide appropriate confirmation, 802.3AF/AT/BT injector will not be able to power up, which means that the POE fuel injector will check the power, and if the power supply does not meet the requirements of the device that has won, this power will 'T lifts the power to ensure the security of the POE device. Generally, the voltage of 802.3 AF/AT/BT POE is always 44 to 57 volts.
However, the POE technology adopted by a passive POE injector does not meet 802.3AF, 802.3AT or 802.3BT standards. Passive POE devices are usually run on DC 18 to 48. If an error voltage is connected, it may cause permanent electrical damage to the device.
12V VS 24V VS 48V POE fuel injection
According to the output power voltage they can provide, the POE fuel injector can be divided into 12V, 24V and 48V. When buying a POE injector, you need to use the voltage standard of the POE device that needs to be powered to consider its voltage. In fact, in addition to the two categories above, the POE fuel injector can also be allocated according to the port number, such as a single port POE syringe, port POE syringe, and so on.
How to use a POE Injector?
POE injectors provide POE -based POE, POE+and POE ++ compatible devices, while providing POE, they perform well in sending data. In a practical application solution, POE injectors act as intermediaries that connect non -POOE switches and POE compatible devices. Device such as IP cameras or wireless access points will be powered by the POE fuel injector.
Taking an IP camera as an example, the power steps will be explained below. What you need is an IP camera, a POE adapter (depending on the number of power IP cameras), standard network switches and CAT5E, CAT6 or CAT6A Ethernet patch cables.
1. Test all devices to ensure the management of IP cameras, POE injectors and cameras. Before installing an IP camera, make all video and network configuration.
2. Insert the Ethernet cable into the power or POE port of the POE injector, and insert it into the POE port of the IP camera.
3. Install the IP camera in a place with enough light so that it can capture clear images on the screen.
4. Insert another Ethernet cable to connect the Ethernet or data port and Ethernet switch to the fuel injector.
5.Insert the injector electric line into the local AC power socket.
