Jointech's intelligent container monitoring device JT705A is used for ISO containers, reefer container, and van truck applications. It has real-time tracking, online or near-field offline unsealing, cargo surrounding environment detection, unlocking status monitoring, and other functions. This Jointech device can be integrated to the GpsGate platform to send an alarm when the position of the container door or the temperature inside the container changes, detect door opening and cargo leaving the container, and control illegal door opening and cargo theft.
