Adding cameras

Hope I'm in the right place, apologies if not, I have a ZOSI cctv system with BNC cables to the cameras, I'm looking at putting 2 cameras out the back of my house, is there any way of doing this with out having to put the bnc cables through the house, like a bnc signal sender of some kind? Thanks.

Distance between dvr and camera will be about 70 feet. With 3 walls in between.

dont do it wireless unless you will pay the price.
the cheap wireless video kits are working on 2.4ghrz

thats realy sh#tty because hole 2.4ghrz band is full with WiFi, doorbells, remote controls, microwaves and more wireless products.

be sure you get a wireless kit for 5ghrz or higher.

best way stay just a network cable to and adapter for video signal, cheaper and much better and reliable signal.
