For easy installation and IP configuration, the camera employs Power over Ethernet (PoE) IEEE802.3af, which supplies power and transmits images through a single cable. No separate power supply is required and all one has to do is connect the cable to the PoE switch or the PoE adapter for it to work. Also, the one-touch fitting mechanism means that to install the component to the desired location, just simply align the recessed part of the main unit to the protruding part of the attached mounting bracket and rotate the main unit clockwise, ensuring the fit.
