Purchased this product based on other customer feedback. Unfortunately, I ended up returning this product through my own fault - I did not realize that the camera required easy access to an outdoor outlet and the wire with each camera is only 6 feet in length. I did get in touch with the vendor's customer service department, who responded immediately. One option would have been to mount the camera to the inside of a window frame if the window had clear glass. In my case, the clearance was too narrow to allow this. I can tell you that the equipment appeared to be extremely well made and the customer service department is extremely responsive.
