Safety for school staff
A new survey commissioned by SVT shows that reports of violence in schools have doubled over the past five years. The threat exists both against teachers and students, sometimes very young ones.
At Crystal Alarm, we believe that teachers and students have the right to feel safe in the environment they spend their days in. We don't think an app alone can solve these problems, but with the Crystal Alarm app on your phone and a personal alarm button in your pocket, we can not only help school management comply with workplace safety regulations but also give school staff greater peace of mind.
We are also developing several new features tailored to the school environment, which we hope will make a real difference to the level of preparedness and security that staff experience every day.
Beacon Tuner for Android Devices
Crystal Alarm launches Beacon Tuner for Android, an app that simplifies the installation and maintenance of iBeacons for indoor positioning. The app displays all active beacons sorted by proximity, battery level per device, and enables colour coding to, for example, identify floor levels. Battery levels are automatically synced to the Self-Service Portal. Launch is planned for April.

Crystal Alarm announces that their new personal alarm, the Crystal Button CB20, has received a strong reception since launch — with nearly 5,000 units delivered and not a single return. The button has been designed for demanding environments such as industrial, healthcare, and logistics settings, offering a range of up to 400 metres, a five-year battery life, and an IP67 rating. The CB20 uses a proprietary communication protocol for greater reliability than standard Bluetooth, and can be integrated with the Crystal Alarm App, Wi-Fi positioning, and Cisco infrastructure.
