The VB-C500VD supports IEEE 802.3af compliant Power over Ethernet (PoE) technology, which allows the use of a single LAN cable to both power the camera and transfer video and audio data when connected to a PoE switch. Because a power cable is not required, the camera can be installed at sites without readily accessible AC outlets. And because PoE eliminates the cost of running expensive power cabling to the device, installation costs are kept to a minimum. There is no need for additional electrical constructions once you connect the camera to a PoE switch.
In addition, the VB-C500VD can be powered using an external power supply (AC24V / DC12V) using the optional AC adapter (PA-V17) and power interface cable (WP500-VB).
