What you get with SnapKey Sensors

Door open/close detection

IoT sensors precisely record when a door is opened or closed — both for authorized unlocks and unauthorized attempts.

Linked with lock data

Sensor information is combined with SnapKey’s log of lock/unlock events, so you always know why and how the door was opened.

Open-door alerts

Get instant alerts if a door is left open too long — reducing risks of intrusion or downtime.

Intrusion detection

When unauthorized openings are detected, the system can trigger alarms and log the event for investigation.

Full documentation & compliance

SnapKey Sensors make it easy to meet CER and NIS2 by documenting all access events with time, date and cause.
