Hey, guys, I bought a cctv camera from a security system company (
http://cspalarms.ca/cctvsecuritycameras/ ). In the middle of the night, I heard a bang from outside but I didn't give it much thought then. When I checked the recording the next day I couldn't see the recording clearly. There were a lot of snowy bars on the screen. What do I do to fix this problem? Any thoughts on this would be great.
