It seems that over the summer (hot) months, I get false alarms on hard-wired motion detectors (DSC BV-500). When looking at when they happen, it's always when I've dialed the air conditioning back to about 80 degrees and it's warmer than the AC setpoint outside, so the house actually heats up to this point. For that reason, I'm thinking that it's heat-related...
The PIRs are in high-traffic areas (hallways, etc), and don't have direct view of windows or heating/cooling vents. False alarms only seem to happen a few times in the summer months when it's hot, and that's how I've come to this conclusion that it's heat-related.
After digging into this and reading, it looks like there's a few options:
1.) Purchase dual tech motion detectors
2.) Set the BV-500 detection jumper from the factory default of "FAST" to "SLOW"
3.) Cross zone the PIRs
Any thoughts on what is the best approach from a security / reliability standpoint?
If it's option #1, what's the best dual-tech wired motion detector at this point?
Thanks!
