Product information

Description

The Tellur TLL331121 Motion Detector is a wireless passive infrared (PIR) sensor designed to detect movement up to 6 metres. It connects to 2.4 GHz WiFi (IEEE 802.11b/g/n) and integrates with the Tellur Smart app to send push notifications when motion is detected or when tampering is attempted. Compact dimensions (48 × 48 × 50 mm) and white finish allow discreet installation in homes and offices. The sensor is powered by a CR123A battery and can operate for up to one year under typical conditions.

Advantages

The device provides real-time push notifications through the Tellur Smart app and supports custom smart scenarios. It detects attempts to detach the unit and uses the widely supported 2.4 GHz WiFi band for reliable connectivity. Small size enables flexible placement and simple integration into existing SmartHome setups.

Suitable for (tasks / use cases)

  • Home security monitoring in rooms, corridors and entryways
  • Office motion detection for non-working hours
  • Integration into automated smart scenarios (lighting, alarms)
  • Temporary or permanent installations where compact sensors are required

How to use

Install the CR123A battery and mount the sensor at a location with a clear view of the monitored area, typically 1.8–2.4 metres above the floor for optimal coverage. Connect the device to your 2.4 GHz WiFi network using the Tellur Smart app and follow the in-app pairing instructions. Configure notification settings and include the sensor in desired smart scenarios (for example, triggering lights or sending alerts). Test detection by walking through the coverage area and adjusting position or angle if necessary.

Usage recommendations

Place the sensor away from direct heat sources, air vents and reflective surfaces to reduce false triggers. Use indoor mounting in dry locations and replace the CR123A battery when low battery notifications appear in the app. Ensure your router supports 2.4 GHz WiFi and maintain a stable internet connection for reliable notifications.
