●
Flexible power options. The camera supports Power over Ethernet (PoE) 802.3af, 12 VDC, or 24 VAC
power through an optional external power supply.
●
Medianet support. The camera supports the Cisco Medianet interface. When connected to a Cisco switch
that also supports Medianet, the switch recognizes the camera as a video endpoint and then uses
SmartPort macros to set the right network parameters for the video stream on the network. In addition, the
camera can be automatically discovered and configured when connected to Cisco Video Surveillance
Manager 7.0, thereby minimizing installation time and cost.
