 How far can you run the CAT5 cable for CCTV? The basis of structured cabling is that there is a standard data cabling specification that applies to all technology. Therefore whatever the technology, it will run the same over-standardized cabling. Thus the maximum distance of 90 meters the CAT5E applies to CCTV, as well as it does for computers, Wi-Fi, telephones etc. The 90 meters allows for 5 meters patch leads at each end. However, a 100 meters direct link is also allowed, so this could apply to a direct link to a CCTV camera. Can I run HDMI over CAT5? CAT5E has the ability to transfer HDMI signals over its cable. This is done via a transmitter and receiver that plug into each end. However, it is recommended that a minimum of CAT6 and even CAT6A is used for the connection due to their additional bandwidth and speed capability.
