As a community group we are wanting to get an internet connection to a DVR 80 meters external line of site distance. Which way should we go - cable or wireless? Have a budget of about $750. Appreciate any informed comments!
Thanks

Personally I'd go cable as the wireless may have problems, the further away from the source the lower the signal strength. Ethernet cable can easily handle 100Mtrs before problems may start.

Thanks - Black External Cat 5 be ok? Not looking for ultra performance here.

The colour doesn't mean a lot, but external cable, designed to be outside would be better/harder wearing than std cable (they come in lots of different colours)My cables that run from the house to the workshop are all in electrical conduit, buried under ground, only std cable, mainly for protection -- its a real bugger if you are digging and cut through a cable :(

Wainui: I have heard from an electrician that networking cable and electrical wires are not meant to run along side each other for straight lengths due to interference from the electrical current field, how have you overcome this issue?

No electrical wires in this duct.

Use shielded network cable

Correct. Move them or run it in a shielded tray.

Personally I'd go wifi for the link.

Something like that, but make sure you turn the broadcast power down.

No electrical wires in this duct. Thats the One :thumbs: All that are in mine are 4 Ethernet cables. The power cable was already there, someplace, under the other end of the workshop.

1 is for the main connection, another for the telephone lines, and two spares

Their gear is awesome, i helped put in a link about 1km over tidal water using their bullets and it's rock solid.

We are decking out our office with their unifi AP's that kinda look like smoke detectors, awesome centralized management software etc, for the $ you can not go wrong.

oh helpful to know, do they do a wireless repeater?
My cousin needs on to repeat his wifi network further.
Stupid router has internal aerials so gets rubbish coverage.

cables ( security, reliability, speed, less chance of data interference ) if it isn't going to be near electrical or other data cables then cat 5 utp will be fine if it is going to share a space with other data cables than cat5 or 5e stp will be the way to go ( utp = unshielded twisted pairs , stp shielded twisted pairs its all in the name. )
