Networking and PoE
The latest Intercoms, Surveillance Cameras and Gate Controls use WiFi, 4G or Network Cable to connect to each other rather than conventional analogue cabling and are powered either with 12V from a Power adaptor or if using a Network Cable, power can be injected into the network cable using Power over Ethernet (PoE) technology, which is handy because it saves having to run data and power cable to devices and one power adaptor can be used to power a number of devices.
