Purchased a C510W 3 months ago , perfect for what I required until out of the blue I find that it cant have the Motion Tracking on without the Motion Detection. As I had it set up to detect and track people only this facility is now redundant the camera now detects everything that passes in front of it. I cant enable Motion Tracking without the following advice.." TURNING ON MOTION TRACKING WILL AUTOMATICALLY ENABLE THE MOTION DETECTION FEATURE" I don't want this for what i use the camera for. The camera worked perfectly well for 3 months until some fool decided to come up with this stupid update. I would like a full refund !!
