Hi All,

I have a job that requires me to put 2 IP cameras in two different building which are 100 metres apart. Ideally I would like to link them up using CAT5 cable. However the recommended limitation of CAT5 is 100 metres. It is a bit risky to try it out as we would need to dig up the ground to lay the cable.

There are 2 alternative,

1) Thin Ethernet base 2 - that is using RG58 and have converter at both ends.

2) Ethernet to Fibre - using fibre and have converter at both ends.

What do you think? Have any of you guys tried any of the above methods? If so, what are the pros and cons.

Thanks in advance.

Best regards,

Edward

hi Edward,

tbh, for the cost of the fiber optic cable against if you will have to dig up the road again i'd run it anyway, anjust get the pre-ended legnths to order. it's the transponders and termination which cost's the big money.

if the roads got to come up anyway, why not just ask for a bigger bore conduit to cater for any later requirements? then if they don't do it, they can't look to you for not suggesting it can they (so they pay not you).

No it isnt 100m for cat5, maybe it is for when using it for networks, but certainly not for cameras, it will easily run to 300m with passive baluns.

He said IP cameras, which presumably means on a network .......................

there is only one answer that is correct: fibre

Once again, I find myself agreeing 100% with the man from coldshire :!:

Why not try setting the camera's up in a workshop with a 120m coil of cat5e in between and see if it works

I was told by one of my suppliers that cat5e was no longer restricted to 100m those parameters were dropped a while ago even on networks but i will check that again as my fluke dsp will fail test results over 100m.

Or you could use a wireless lan link with patch antenna.

Would probably be cheaper than digging the road up and the cable required.

just gona say use a switch

Ive had IP cams working over 100m, I had one at 132m that needed a switch adding partway though.

We have used cat 5 up to 150m with standard baluns and all was ok.

The one we fitted with a 250m run would not work. We had to fit video amd and ground loop isolators as it was also on another phase.
