The ComNet series video transmitters and receivers support the transmission of one, two, or four independent short-haul quality 10-bit digital video signals and one, two, or four contact closures in the direction of the video over multimode or single mode optical fibers. This module is universally compatible with major CCTV camera manufacturers. The receivers are compatible with the FVT10C1(M,S)1[/M] series or FVT1(M,S)1/M* single channel transmitters. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.

The ComNet™ FVT/FVR40D2I1C4E environmentally hardened units provide transmission of four independent video channels and two bi-directional data channels. They also provide transmission of one Aiphone™ intercom channel and four contact closure channels with tamper supervision in addition to one 10/100Mbps Ethernet channel. The FVT/FVR40D2I1C4E has dual SFP optical ports to provide a redundant point-to-point fail safe topology in the event of loss of one fiber or one optical module. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.

The ComNetTM FVT412M1 and FVR412M1 transmit four (4) channels of video utilizing state of the art digital encoding and decoding for high-quality video transmission, along with two (2) channels of bi-directional data over one multimode optical fiber. This equipment is environmentally hardened and suitable for use in unconditioned roadside or out-of plant installations. The FVT/FVR412 is compatible with NTSC, PAL and SECAM video transmission protocols and supports bi-directional RS232, 422 and RS485 (2 & 4 Wire) data. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are required.

The ComNet FVT/FVR412 Series transmits four channels of video utilizing state of the art digital encoding and decoding for high-quality video transmission, along with two channels of bi-directional data and one bi-directional contact closure over one single mode or multimode optical fiber. This equipment is environmentally hardened and suitable for use in unconditioned roadside or out-of plant installations. The FVT/FVR412 is compatible with NTSC, PAL and SECAM video transmission protocols and supports bi-directional RS232, 422 and 485-2/4W data.
