What is remote multi-point immobilisation?

You can remotely immobilise the asset/equipment by click of a button by within your portal control centre.

Remotely immobilising prevents anyone using your asset/equipment if it gets into the wrong hands until such time that you re-active the ‘Smart-Lead’, keeping you in control of your assets at all times.

Whilst the asset is immobilised it can still be tracked and traced.

Please see illustrative video here.

What is Sentry Guard?

Applying this feature sets up an early warning system from a given area you designate on the map via your personal control centre. 

Set your Sentry Guard fence on your control centre map and if the asset is moved by anyone outside of this designated area Sentry Guard will notify you via text or email that your asset has moved which allows you to then track and trace. 

What is FOTA?

FOTA capability allows automated software updates direct to your ‘smart-lead’ ensuring up-to-date security features maximise ongoing asset protection.
