The ComNet FVR4C4B Video and Contact Closure Receiver unit supports four independent channels of video and four independent dry contact closures over four separate optical fibers. The FVT1C1B-M video mini-transmitter supports transmission of a fixed video and a contact closure signal using an 8-bit digitally encoded signal on one multimode or single mode fiber optic cable. State-of-the-art 8-bit digital decoding is utilized for the four video channels. The contact closure channels may be used with triggered-event CCTV camera systems, or other applications such as access controlled gates, doors, or other equipment requiring remote actuation and control.
