The VB-H41 gives you great installation flexibility as it will accept a variety of power options. Whether your situation works best with 12vDC, 24vAC or Power over Ethernet, it will accommodate your needs. The low power consumption of the VB-H41 allows the use of standard PoE (IEEE 802.3af), enabling a single LAN cable to both power the camera and transfer video and audio data. Connecting to a Power over Ethernet switch or injector eliminates the need to run AC connections to installation sites of the cameras. This can help keep installation costs to a minimum.
