Security video multiplexer?

A colleague wants to install some additional cameras to an existing security system that has a long single coax run already in place. He wants to know if there is a "video multiplexer" that can be connected at both ends to run multiple video feeds on the existing coax.

Any pointers? My limited searching hasn't turned up anything useful yet.

Wireless might not be an option due to obstacles and distance, so wants to explore using the exiting coax first before considering that or a new cable run.

Thanks Dave.

Use video modulators on different channels for each camera, if you need them all at the same time, or put a remote selector at the existing camera to select one at a time.

There is but not terribly successful . is physically possible running a multicore cable like some runs of cat5E with baluns would be more stable

how many more cams as the hardware cost makes it very expensive due to running mixed modulators for differing in and out frequency's..
