Things just got more complicated...
My wife has a thing about visible wires. Given that it is impossible to install this kit without at least some wires being visible, coming out of the house, down the wall and into the garden, I'm going to have to investigate wireless options.
Any suggestions? Is wireless more expensive?
Actually I can probably manage mostly wired cameras, by mounting on the house rather than the garage. But I would need to go wireless for the gate camera.
