Looking at replacing 8 year old analog cameras in our CCTV network with high end IP ones and one contractor wants to also replace the Cat 5 with fibre.
The question is this.
Over about 250 metres is there any SIGNIFICANT quality difference between Cat 5 and fibre?
Just trying to figure if it is cost effective!
Thanks

well, cat5e for ethernet is specced to go 100 meters, so good on the installer for wanting to do it right.

250m is WAY outside spec for a run for cat5/cat6 without some sort of powered repeater (e.g. switch), actually, two of them. The installer is right to suggest fibre. Any installer who did not at least raise the distance as an issue for cat5/6 would be one I would avoid.

You can run analogue camera over cat5e over 250m with baluns.

You can't run Ethernet for IP camera over 250m - it's well beyond the 100m limitation of Ethernet (which you can push to 150m in a really good environment if you're lucky).

The only two options are fibre, or 2 Ethernet power boosters to use the cat5e cable.
