How It Works

A magnetic contact on the door, a probe on the frame side, 0.4m of cable between them — the moment the magnet leaves, the state flips to OPEN.

Physical Security for Racks

Every door opening becomes a timestamped event — unauthorized access alarms in real time, and an audit trail for the openings that were authorized.

Door Contact or Light Sensor?

For remote edge shelters and MDF/IDF sites, the light sensor detects presence inside the room — and is harder to defeat than a contact on the door.

Where to Install

Front and rear rack doors, colo cabinets and server room doors — including the rear door that most monitoring plans forget.

Alerting & Integration

OPEN/CLOSE state with immediate alerts via email, SNMP traps & optional SMS — straight into your BMS over Modbus TCP, BACnet IP or Modbus RTU.
