Lone worker alarm on your phone, now with support for SOS Access V4
Earlier this year, we announced that we had begun work on integrating with SOS Access V4 — an alarm transmission protocol that enables Crystal Alarm to connect to multiple alarm receiving centres. We are now pleased to announce that on Sunday 18th October, we launched the version of our cloud service that has been tested with the new protocol. Alarm receiving centres using SOS Access V4 will therefore now be available as an option for enterprise customers who wish to connect Crystal Alarm to an external alarm receiving centre.

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.
