|These are four motion detectors from the old security system of the OKCPRG research site I have modified for use on investigations. I wired in buzzers, LEDs, switches, took out the RF transmitters, and put 1/4" camera mounts on the them. The only problem is they go off every 35 seconds as a test. I am working on resolving that problem. I can mount these to retractable mini-tripods, like shown, or any other camera tripod.
