Tamper Detection & Prevention
Multi-Layer Tamper Protection:
Olarm ENTRY uses five independent detection methods to ensure your sensor can't be disabled or removed without you knowing. If someone tries to tamper with the device, you'll be notified immediately - even if they cut power or remove the device.
Detection Type
Technology
Alert Method
What Happens
Wall Tamper
Breakaway tab on mounting plate
Instant alert via Olarm APP & Signal
Alert is sent if device is pried off wall and tab breaks
Lid Open / Close
Mechanical sensor inside enclosure
Instant alert via Olarm APP & Signal
Opening the lid will send an immediate alert
Impact and Movement Detection
Accelerometer-based
Instant alert via Olarm APP & Signal
Any physical impact or movement triggers tamper alert
Tamper Response:
When tampering is detected, Olarm ENTRY immediately:
Sends push notification to your Olarm APP
Logs event in device history with timestamp
Sends signal to monitoring station (if professionally monitored)
