ONE WAY RELAY CONTROL OVER IP VIDEO
The IP4x4T/R is a remote relay control system that puts one-way contact relay controls onto any IP video cable without affecting the IP video. Use this to install an access control system or an emergency button out at the camera when the cost of running additional wires is prohibitive. If you need to dig a trench, break holes in walls or tear up concrete, this unit can get you the remote control you need without the heavy labor and expense. Send relay control signals over the same network cable used for your IP Video. The IP4x4T/R set can be used on any twisted pair wire and does not require an IP signal to work. Say you want to have a push button at a gate to announce someone at the gate or control the gate access with as many as 4 different controls in one direction. That is a total of 4 relay controls on the same network cable that brings you the IP video signal. The units work by using the direct copper connection between the transmitter and receiver with no switches or other equipment in between them.
The units have LED indicators for both the input switch signals and the relay output signals to monitor the status of all incoming and outgoing signals. The relay outputs can be set for normally open or normally closed contacts to work with any external equipment requirements. The transmitter and receiver units are powered by 24 Volts AC or DC and can use the same power supply as the camera. This unit is also available in a 12 VDC version at no additional cost, use part number IP4x4T/R-12 at time of order.
For added security the system has a “system alarm” relay and LED to indicate loss of communication between the transmitter and receiver units caused by a signal disconnect or a cable failure. You get both transmitter and receiver units with power supplies all included when you order the IP4x4T/R, and you can order this unit with supervised alarm contacts for even more security at no additional cost. When ordering a supervised system, specify the loop resistance and order part number IP4x4T/R-S. The units will pass “P.O.E. on the 4-5, 7-8 wires”.
