03 · Alarms & Access
An alarm that talks to your cameras
A UniFi intruder alarm — siren, gateway and wireless sensors — plus smart door access, all managed from the same app as your WiFi and CCTV.
Part of the same system
The alarm lives in UniFi Protect alongside your cameras — one app to arm, disarm and review what happened, not a separate keypad ecosystem.
Wireless sensors, tidy install
Motion, door, leak and environmental sensors connect wirelessly through a gateway in the rack — no sensor cabling chased into walls.
A siren that means it
A PoE-powered siren with strobe, mounted where it counts. Triggered by sensors, cameras or both.
Smarter triggers
Pair detections — a person on camera plus motion inside — to cut false alarms, and have cameras start recording the moment a sensor trips.
Alerts to your phone
Instant notifications with a snapshot of what triggered them, wherever you are.
Doors, handled too
Smart readers and door hubs let family, staff or guests unlock with a fob, card or phone — and you can grant or remove access from anywhere.
