Monitor and Protect Trailers

The Cargo Defender DoorSecure security system is designed to monitor and protect trailers from cargo theft and unauthorized access to the trailer. The security system is compatible for 12/24v power supply making it ideal for vans, rigid trucks and trailers. The security system has a built in backup up power supply meaning it can remain active when the trailer is disconnected from the tractor unit or the power is cut.

When an alert is activated the system sets off an extremely high decibel audio alarm to deter the intruder along with alerting programmed contacts by email or sms. The systems on line security platform allows your fleet manager to monitor and control the system from any computer or smart phone with internet access. The platform displays the location of the truck/trailer and instantly displays any alarm events. The user can remotely arm disarm the security system through the platform.
