Warning: A job in a big old house in Savannah made me rethink my whole approach to motion sensors

I was installing a system in this huge, three story historic home last month, and the client kept getting false alarms from the main hall. Turns out, the afternoon sun coming through a stained glass window was hitting a vase just right, making the sensor think something was moving. We spent two days trying to fix it before I just moved the sensor to a different wall. Now I'm torn: do you guys always stick to the standard placement for motion detectors, or do you scout the room at different times of day first? I used to think the book was always right, but that job cost me a lot of extra time.

So @davidh88, how many jobs did it take before you ditched the book completely?

That sun through old windows is a real pain. Had a similar thing with a ceiling fan casting weird shadows at dusk. Makes you wonder if the standard spots are just a starting point, right?
