GSM listening device in smoke detector

GSM listening device in smoke detector housing – inconspicuous audio surveillance for up to 70 days

Maximum camouflage in an everyday object: This GSM listening device is integrated into an inconspicuous smoke detector housing and is suitable for long-term acoustic surveillance tasks indoors. You can access the room acoustics live via the mobile network, regardless of the distance.

Operation is uncomplicated: You call the inserted SIM card and listen directly to the surroundings of the device. With activated voice activation the device can automatically call back as soon as noise activity is detected. The integrated 6,000 mAh lithium battery enables a standby time of up to 70 days and is therefore also suitable for long-term use without permanent power supply.

Your advantages in discreet long-term deployments:

• Inconspicuous design – integriert in ein alltägliches Rauchmeldergehäuse
• Long-term operation – bis zu 70 Tage Standby-Zeit
• voice activation – automatischer Rückruf bei erkannter Geräuschaktivität
• Worldwide audio access – über das Mobilfunknetz unabhängig von der Entfernung erreichbar
• Sensitive microphone – akustische Erfassung im Bereich von ca. 10 Metern
• Discreet operation – keine akustischen oder optischen Hinweise auf das integrierte GSM-Modul

Our technical assessment

The special strength of this model lies in the combination of discreet placement and comparatively high battery capacity. A smoke detector is typically located at an elevated position in the room. This can be acoustically advantageous because the microphone is not immediately shielded by furniture or other objects, and sound can spread relatively freely from different directions.

With 6,000 mAh, this model offers significantly more energy reserve than typical mini-GSM devices. At the same time, it remains independent of a permanent mains power supply. This makes it particularly suitable for applications where a fixed power outlet or a visible power supply is not available, but the device should still remain operational over a longer period.

For extremely long unattended operations, our POWER and EXTREMPOWER models with significantly larger batteries are the better choice. However, if uncompromising continuous operation without charging cycles can be achieved, mains-powered solutions such as GSM wall sockets or power strips offer advantages. The GSM smoke detector is therefore particularly interesting when discrete room placement, good acoustic position, and long battery autonomy are to be combined.

Typical application scenarios:

• Long-term acoustic monitoring of offices or meeting rooms
• Discrete applications in apartments, vacation homes, or other indoor spaces
• Rooms where elevated and discreet placement is sensible
• Applications without permanent mains power supply
• Acoustic room monitoring with automatic notification of noise activity
