I'm looking to install several CCTV cameras outdoors, in a garden, each approximately 20-100 meters away from the main building. I've looked at some youtube videos on installing POE cables underground and it seems that some people also feed the cable through conduit. Conduit over a long distance seems to be a little expensive, so ideally I would just like to go for the best quality burial cable. If the cable is strong enough, then surely conduit wouldn't be necessary? Has anyone here installed direct burial POE ethernet cables?
