Hardwired vs wireless motion detectors - found out the hard way

I swapped out a bunch of old hardwired motion detectors for wireless ones on a job in Austin last month, thinking it would save time on running cable. But the wireless units kept triggering false alarms from a neighbor's garage door opener, and I spent three days troubleshooting before switching back to hardwired. Has anyone else had trouble with RF interference messing up their installs in dense neighborhoods?

Holy crap, a neighbor's garage door opener caused all that?

Totally misread that @johnson.jesse and thought my key fob was haunted.

@johnson.jesse yep, dead serious. those 900 MHz units are super common in residential areas and they can bleed all over the same frequencies. I had one install in a condo complex where a kid's RC car would trigger the whole system every afternoon. Hardwired is a pain to run but at least it doesn't pick up random radio noise from down the street.
