I had a neighbor that I thought was vandalizing my yard, so I installed these in the front windows, using inexpensive TV/VCRs from the pawn shop for recording. Just taped the cameras to the glass and turned on the recorder when I was leaving the house.I caught my intruder--but it turned out to be another neighbor's dog, who was getting out and having a romp in my yard. I also got to see birds, squirrels, and cats wandering across the field of view.The main drawback of this camera is that it has a narrow field of view. Even the wide angle model (a little more expensive) won't possibly cover an entire front yard. I had to install two, and even then, there was an enormous "dead zone" where someone could sneak past the cameras.The price is excellent, and the longer cord helps run it from the window to where your recorder is sitting.Not a bad product and did the job I needed.
