This equipment allow the user to send multiple video signals over a single coax cable. Perfect solution to applications where additional cameras are needed, but only a single coax cable is available. Simply attach each camera to a unique single channel injector, then use a combiner to send them all together. Additional injectors may be added and combined anywhere along the cable to add additional cameras. The video extractors are available in 4, 8, & 16 channels, and may also be placed anywhere along the coax run to selectively extract the desired cameras at that location. The out of box signal strength allows for runs up to 1000 ft. and beyond. Amplifiers are available if greater distances are required.
