We appreciate the integration possibilities in the command center that helps us to cross reference GPS and our own backend knowledge of the staff and their missions.

Simple integration with external alarm buttons and the ability to work standalone without any additional hardware. Simple and intuitive graphical user interface.

Not really part of the application but more into OS integration where sometimes new security features in the android OS interfere with the application. The supplier is always fast to alert us to this and thankfully there is a test function that we require our users to use periodically.

easy to use as long as it is installed as an app in the phone and that you alarm by the side button on the phone

we have had several types of alarms and they have not been so "easily usable". By having it as an app in the mobile phone, it has made it easier for staff working in the field.

Battery demanding, and you have to keep an eye on the external box so that it has contact with the mobile at all times

Very easy to use and user friendly too, it also support multiple functionality. I am impressed with timer alarm functionality most.

I am satisfied with features; I found nothing bad.

- Behaviour - Exceptional accessibility - Flexibility - Solution-oriented

At the time of our cooperation, Crystal Alarm did not have a robust solution for indoor positioning underground. Maybe it exists today.

- Once set up, it is very easy to use. You activate the alarm by the push of a button on the phone, but there is also the option of using an external button. - The administrative portal is really user friendly. You do not need to spend a lot of time looking through user guides, everything is pretty straight-forward.

- It can be a little stressful to receive an alarm notification. The Crystal Alarm app plays a loud alarm sound and you get two notifications, one from the app and one as a text message containing a link to the alarm information. Both notifications takes you to the same information so you just need to use one of them but for some people it can feel like there is a lot of things happening at once.
