What is an external BLE SOS button?


Our External BLE SOS buttons are waterproof, thin & light (weight less than 10gr!) devices with a CR2032 battery that can be easily replaced when needed (Guard having the SOS button connected with the QR-Patrol app on his phone gets informed with a simple message within the app)! They can be easily attached for example to keys or clothes, or can be worn as IDs around the Guard’s neck.

They are based on Bluetooth low energy (BLE) (Guard’s mobile device has to support BLE technology).

Note: BLE technology is supported by Android OS version 4.4 and above and iOS version 8.0 and above.
