I used the Lamson/Ge pir and the Cannon af set up on my deer cam. It bench tests great, but when l put it in the field it will take several pics and then it is like the relay won't release in the pir. I can unplug my camera from the pir and I can take a pic with the camera and I can plug it back in and everything is fine. I don't have to turn my camera off or anything it is not going to sleep. It is like the relay in the pir still had the camera activated, but when I unplug the camera the pir releases and resets. Anybody have any ideas as to what might be causing it?
