The product boasts power and communications over POE and IPV6 technologies and processes video, audio and access control from a single station. The entry station has an LCD display that lists the tenants/employees that the visitor can call to gain access. Once the call is initiated, the receiving monitor will automatically display video of the person. If approved, the tenant can unlock the door/gate from a touch screen icon on the monitor. There is also a built in card reader and keypad for employee access control which is integrated with the Net2 Access System. So instead of piecing together two disparate systems, use one CAT 5-6 cable and the Paxton IP video intercom for a single solution backed by an industry leading 5 year warranty.
