I am looking for a camera or 2 for the house to record whats going on in the back garden and keep an eye on the cars at the front.

I don't really want to run cables all over the house so wireless preferred, also I don't really want to make holes in walls and mount them outside so internal pointing out of windows would be best I don't have a ladder any more to climb up the side of the house.

Any suggestions on cameras, I would be recording to a windows PC so software solutions as well would be good, motion detection or 24/7 recording I'm not too bothered as its a pretty busy street and with motion detection would probably record most of the time anyway.
