 Question by Stephen McGuffey posted 26 Jan 2006
Concerning UTP cable (Cat 5) being installed for CCTV applications, what are the inherent problems with Radio Frequency Interference for cable Runs between 3000 and 5000'. In particular I have a pending installation in a trucking yard which uses radio transmission between all trucks, the dispatch trailer and the main office. Due to the distances I am recommending fiber optic cableing to the customer however I could use additional information to justify the change.

When using cat5 at the above listed distances in CCTV applications with PTZ cameras, could joystick comand delays be noticed?

Should surge/lightning protection units be installed as required by EIA/TIA standards for data cabling? The infrastructure consists of UG conduit with the cabling terminating on cameras at ~15' on wood telephone poles.

Dear Stephen,

First, all links of category 5 are limited to 90 meters (295') I would think there are a few problems with a 3,000 to 5,000 foot run: Attenuation; splices; signal strength, data corruption.

I believe you are in need of a professional CCTV designer/engineer to overcome your situation and achieve the desired operation of the system.
