Ordered these two and plugged them into my existing system as an additional couple of cameras. My initial system was up and running so these were just plug and play. The lead was long enough but it's not as long as the leads that come with the outdoor cameras.

Mounting them is easy enough, drill a few holes and screw them tight. Getting a level picture is a bit trickier as there's no bottom dead centre marked on the round body of the camera. I tried to level them but my wife doesn't know her left from right. I've accepted the odd viewing angle, even though it makes my house look like the Joker's lair from 60's Batman.

The picture is very clear and will identify a face and the system allows zooming in. The system keeps about 2 weeks of information 24hrs a day from 6 cameras. Whilst it's not an easy 2 second drag and drop, getting the footage onto a thumb drive is a 5 minute job and it can be saved as a windows media file.

Not the cheapest system, but so far these seem quite good.
