I wondered. I hear how the MS-20 and even RS-PIR have a sensing range beyond the max 32 feet of the OWL PF which seems to be the camera of choice due to the flash power. If a relay is a switch could I wire a small but powerful xenon bulb flashlight to the switch to supplement the flash and light up even farther? I know there must be a reason this wont work. Does someone know why?
