Horizontal Cabling for Video Surveillance Guide
There are a few options when it comes to professionally installing horizontal cabling for video surveillance networks. The three options examined here are:
- 'Direct Attached', where the first terminates the field cabling with an RJ45 modular plug, and connects it directly to the camera.
- 'Jack & Patch', where the cables are first terminated to a jack or patch panel, and then connected to security devices by patch cord.
- 'MPTL', Modular Plug Terminated Link is a hybrid of the two methods above with a female jack / patch panel at the head end and an RJ45 modular plug on the far end connecting directly to the camera.
Inside this report, we explain the options, tradeoffs, and elaborate on the pros and cons of each method.
