MOTION DETECTION

Post by mustang » Fri Mar 01, 2002 10:33 pm

Does anyone have information on motion detection using a comparison of video frames from an active tv camera?

A very old system is still in use today. It is comprised of a light sensor and suction cup stuck to the screen, and it measures changes in average or ambient light, and the changes when the some one moves in the picture, sets it off. They sell them or you can make them your self. I think I still have a diagram in a old book, but the part #s would be out of production.

What I am really looking for is a means of detecting motion with the x10 cameras and triggering a vcr to record with out using the x10 motion detectors. I have found that the x10 motion sensors do not have enough power when used outside of a stucco building. I would like to avoid using a pc as part of the system.

how about a PIR? Relay contacts in the unit close and they could then swicth the camera on or VCR<p>bodgy

Heres my 2 cents worth, My intel pc cam has a motion detector application built in so that when it detects motion on the pc cam, it emails pictures on the internet, and stops it when the motion stops. other then that cool thingy app , go to this web site they sell motion detecters and devices which detect motion on video signals,

There are websites that show you how to hack ... er ... modify cheap motion detector circuits that you can buy at Walmart. Just do a search for "hack motion detector"<p>Nate
