Our PoE (Power-over-Ethernet) SMART Switch integrates power and data over a single cable providing an easier installation for IP cameras. Simply connect any network cable between the switch and the IP camera (or any IP device) and the switch will automatically detect the settings of most devices and adjust itself accordingly. It will detect a system power overload and disable the PoE function of lower priority PoE ports to maintain the power to higher priority PoE ports. The cost-effective PoE SMART-SWITCH provides an ideal solution to most kinds of local area network congestion problems.
