Update your Sentinel App and PC Client Software

Posted in Uncategorized

We deployed an update to the Sentinel App and PC Client software in December 2022. Older versions of the app and PC Client software will no longer work after Monday 27th February, so please make sure you have the latest version installed.


For those who do not have auto update activated on their smart devices, the Sentinel app will need to be manually updated via Google Play or the Apple App Store.

The updated PC Client software is available to download for free here:

Please contact the helpdesk for any Sentinel queries.
