เซ็นเซอร์ตรวจจับความเคลื่อนไหวเสริม

Setup was a breeze since they just wire right into the existing system, and the range on these is plenty for a hallway or garage. I’ve had zero false alarms from pets, which is exactly what I hoped for when adding a few extra zones.

The PIR sensor picks up heat signatures just as described, so I don't get false alarms from my cat wandering past. Setup was straightforward since it's wired, and it's been rock-solid for a week now. Exactly the simple, video-free coverage I wanted for the back porch.
