There are at least 3 systems:
Three cameras on the outside back wall facing the Yard and back door, connected to 2 monitors, one inside the back door and one on the ground floor by the lift, both black & white. There is a small control box on top of the monitor by the back door, no DVR or anything fancy, not know if the cameras are colour.
One camera on the wall above the stairs to the basement connected to a single monitor above the counter, dosn't seem to be a control box. Colour, good quality and a nice camera, PAL.
At least 6 small cameras on the ground floor connected to an 8 channel controller and a TV in the small office area behind the counter. There is also a multi output power supply (12V) attached to the wall in the office that powers the cameras. I've not been able to get it to do anything, needs batteries for the TV's remote.
The cameras are:
- inside the entrance lobby
- outside the entrance lobby
- a connector with no camera outside the entrance lobby
- on the wall behind the entrance lobby
- 2 on pillars on the ground floor
