Cat5e or Cat6? What We Run for Security Cameras and Why

Updated: Jul 31
Cable is the least interesting part of a security install and the most expensive part to redo. Cameras get swapped out every several years. The cable in your walls stays there.
What each one does
Cat5e handles gigabit speeds and carries power over ethernet without trouble. For a typical camera run it is more than enough. Cat6 has tighter construction and better noise handling, which matters on longer runs and in environments with a lot of electrical interference.
Both are rated to the same maximum distance under the standard. The difference shows up at the edges: long runs, high-bandwidth cameras, and cable pulled alongside electrical.
How we decide
Cat5e is our standard for typical camera runs. We move to Cat6 on longer runs, on higher-resolution cameras, on anything feeding a switch or access point rather than a single camera, and anywhere the cable has to share a path with line-voltage wiring.
We would rather put the better cable in on day one than explain later why one camera keeps dropping off the network.
The part that matters more than the category
Honestly, the bigger problem in the field is not Cat5e versus Cat6. It is copper-clad aluminum cable sold as ethernet. It is cheap, it looks the same in the box, and it fails at exactly the thing security cameras need most, which is carrying power reliably over distance. We run solid copper. Every time.
The other one is termination. A perfect run of Cat6 terminated badly performs worse than a clean Cat5e run. Untwisting too much pair at the jack, kinking the cable on a tight bend, or running it zip-tied to a fluorescent ballast will all cause problems that look like camera problems.
If you are building or renovating
This is the cheapest moment you will ever have to do it right. Open walls mean we can run whatever you might want later, not just what you need today. Our low voltage prewire work is built around that idea: pull more than you need now, terminate it properly, label it, and leave the property ready for whatever comes next.
