I had my sytem professionally installed so, no it was working fine from the start. Forgive me for being obvious but have you goy your recorder to multi camera screen mode, you can do this by double clicking on the working camera image.

Mate the cables are all separate one dvr and camara on same run 18 m you only need two power sockets to run the whole system brill set up hope this helps cheers

No I don't think you can . Wired camaras are better anyway . I had a wireless before picture not that good a lot off interference.

The view can only be changed by use of the mouse.
