40 ft. cable run for RS-485, need to be shielded or not?

[serbokl 0]

For purposes of accessing the camera's OSD I would like to run a RS-485 pair about 40 ft. What is the simplest, easiest to find cable type that I could expect to work for this application (non-shielded OK or not)? Is there no readily available cable that has Video, Power, and RS-485, all in one jacket? If so, is it safe to assume that a separate cable is normally used?

Just about any single pair will do - Cat5e, station wire, 18/2... doesn't need to be shielded or overly large-gauge.

 

As for readily-available all-in-one cable: you can use Cat3/5/5e/6 UTP: video on one pair (with baluns), RS-485 on one pair, power on the other two pairs.

Thank you very much for sharing your knowledge/experience. From my reading on the Internet there apparently are some RS-485 applications (not neccessarily CCTV) where people were claiming shielding was important - it had me confused.

Can't think of a one where it would make a difference at only 40', unless it has to pass through the core of a kilovolt transformer or something.
