What are you using for BI alarms?[/QUOTE
For the most part, I use BI to figure out motion. The two exceptions in my system are for the 1831C-PIR and the 5442TM-AS-LED... those cameras are set to trigger their own alerts and BI watches for them (via PullPointSubscription).
The 1831C-PIR has a built-in PIR sensor that's had extremely few false alerts . I wasn't sure how the 5442 would do on accuracy but since it's one of those new "AI" models I figured I'd give it a shot. It too has extremely few false alerts, so I've let it continue doing its own motion detection.
