What is POE technology?
Power Over Ethernet
Powering and powering network closed-circuit equipment is one of the challenges ahead when installing and commissioning an under-grid system. Especially when you have to equip a place with a high number of CCTV cameras. Because in this case, the simultaneous wiring of electricity and network of these equipment is also more complicated and costly. That’s why POE technology can be so cost-effective, in terms of cabling, installation.
In fact, POE technology in network cables provides the possibility that electrical current can also pass through these cables while transmitting data on the network cable. So cameras and other equipment are both powered and transmitted through this channel.
According to the IEEE 802.3at standard, from which POE technology originated, the power of each port is equal to 15.4 watts in the act of transmitting power, which is used for various devices. Well, these values are theoretical and in practice this number comes to 12.95 watts. This is because the resistance and energy dissipation along the cable are not considered.
How much power or power should the POE have?
The wattage of a POE device is one of the factors to consider when buying and selecting. Also, depending on the number of cameras and the size of the project, other specifications such as the number of output ports, the total power of the device and the power consumption of the devices connected to it should be considered.
Applications of POE Technology
wireless scaffolding cameras, wireless phones, network routers, WIFI modems, faxes, printers, sensors, controllers, etc.
Benefits of POE Technology in CCTV
Saving on bedding costs
Ease of installation and flexibility
More and better efficiency
