The Axis Communications T81B22 DC 1-Port 30W Midspan offers an easy, fast, and cost-effective solution for powering network video products, specifically PTZ (pan/tilt/zoom) dome and fixed outdoor network cameras without the need to install power outlets and electrical cabling.
Axis High Power over Ethernet (High PoE) Midspan enables the Axis network video products to receive data and power over the same Ethernet cable. This product makes it easier to install network video products in areas where power cabling and outlets are unavailable. Thus, installation costs are reduced.
The midspan conforms to IEEE 802.3at (maximum 30 W) at 12 VDC input for powering devices with high power requirements on a network. The midspan is also IEEE 802.3af compliant (maximum 15 W) at 12/24 VDC input, which means that it can be used with all Axis network video products with built-in PoE support.
