Just spent 4 hours on a single motion sensor in a 1920s house
Had a job in an old neighborhood, place was built in the 20s. The client wanted a motion sensor in the main hallway, which has these crazy high, ornate ceilings. I mounted the sensor, but it kept giving false alarms every time the old radiator kicked on across the room. I figured it was picking up the heat plume. Spent forever adjusting the angle and the sensitivity settings on the DSC unit, but nothing worked. Finally, after like 3 hours of messing with it, I realized the vibration from the pipes was shaking the whole mounting bracket ever so slightly. I pulled it down, added a thin foam pad behind the bracket to isolate it, and remounted. Problem solved instantly. Has anyone else run into vibration issues in old houses messing with gear like that?
