When it comes to VAN CRIME and vehicle security, adding more LOCKS has for a long time been seen as the go to solution, However the evidence now shows that LOCKS - DO NOT STOP - VAN CRIME … LOCKS BUY YOU TIME This means it takes Thieves a LONGER TIME to break-in. However, A Thief has ALL THE TIME HE NEEDS to operate around a van Because he is UNDETECTED ! and that’s why we made VANGUARDIAN. Firstly A VISIBLE deterrent so a thief can see the vehicle is protected and a POWERFUL, UNIMPEADED, PRE-EMPTIVE ALARM awaits that activates immediately upon sensing CONTACT to draw instant attention to criminal activity … BEFORE DAMAGE IS DONE To eliminate the TIME, the FREE TIME a thief could otherwise operate around a van UNDETECTED, A simple and yet Highley effective solution, removing a thief’s main asset of ANONYIMITY immediately puts a thief on the back foot, changing the dynamic in to a fight or flight situation, Knowing they are now exposed & compromised a thief would rather flee the scene and avoid confrontation. The VANGUARDIAN sensor ALERTS & APP provide an important SECOND LINE of defense & notification by ALERTING the vehicle owner by TEXT ALERT when they are out of range of the audible capacity of the VANGUARDIAN ALARM. The GPS text message ALERT reacts immediately if the vehicle is compromised in a timely manner so that the vehicle owner / driver can respond BEFORE damage or theft.
