I have had lots of problems with my backstreet cameras. Two had the night vision go out and one was just faulty, but they said that it was just hot spots. When I replaced it with a new camera, the hot spots miraculously disappeared. Also their installer was pretty clueless about how to run the software, although he did a good job of installation. Also their system is so complicated that they assume that you know how to do simple things like copy a small portion of your video, or change your password.
