Featuring low cost, high performance and plug & play, the PoE switch TEG1105PD is both a PSE and a PD, designed for such surveillance networking scenarios as roads in parks/communities, medium to large factories, and colleges. Small and delicate, it can be installed in an outdoor waterproof box easily. The switch provides four 10/100/1000 Mbps PoE OUT ports (ports 1 to 4) compliant with IEEE 802.3af and one 10/100/1000 Mbps PoE IN port (port 5) compliant with IEEE 802.3af/at. The maximum PoE output power of the whole switch is 22 W. The switch can supply power and transmit data to low-power APs and IP cameras through CAT5 cables, greatly reducing the cost of the network deployment. It is an ideal choice for wired networking in monitoring scenarios of middle to long distance.
