My CCTV did exactly the same thing!

It’s really annoying you know. I recently installed a few CCTV cameras at the front of the mansion to record anyone coming to the front door. I then hired a small team of maintenance workers to ensure that the cameras remained in working order and I also got a management team to draw up a best practice document and a suitable maintenance schedule. These cameras were cleaned, checked, reviewed, pampered and oiled for weeks and weeks and weeks and weeks and all I got were a few tapes of passing cats and dogs. Then someone put a brick though my window and that’s exactly when the equipment decided to fail. The tapes were blank. BLANK!! Sometimes I don’t know why I bother.
