Its powerful battery means the device remains active for several weeks, while software updates ensure it is always up to date. “Our Spexor mobile alarm device is certain to give users peace of mind – whether they’re at home or out and about,” says Dr. Marko Häckel, the head of sales and alliance management for Spexor. He co-developed and brought Spexor to market with Tobias Riedel, the head of product management and engineering. Setting up the device is incredibly simple: just download the app, scan the QR code, and configure Spexor with the app. 

Spexor is the size of a coffee cup and houses several sensors that detect motion, sound, and changes to air pressure in a radius of approximately five metres around the device. “What sets Bosch’s compact security guard apart are the high precision and intelligent combination of its sensors, enabling Spexor to reliably detect break-ins,” says co-developer Riedel.

If, for instance, the device is placed in garden shed and a football bounces against the window, the sound and pressure sensors detect the change. However, this alone does not set off the alarm. Only when Spexor detects movement inside the shed does the sensitive security device trigger the alarm and send a warning to the user’s smartphone. Depending on the individual settings, the device also sounds an alarm and the built-in LEDs flash red as a direct deterrent to burglars.

The new device incorporates a rechargeable battery, enabling it to be placed almost anywhere that security is important. A Wifi connection or cellular network is all Spexor needs to do its job when a break-in occurs.  Applications include protecting motorhomes when parked or looking after expensive equipment, tools, or winter tyres stored in a garden shed, for example. Spexor can operate and be stored at ambient temperatures of –10 to +60 degrees Celsius. Data privacy was also a top priority in the development of the alarm device: Spexor has no camera and does not analyse or store any voice data. 

It took just 15 months for the alarm device to make the journey from initial product idea to mass production thanks to Bosch’s in-house startup platform, Grow.
