The HOC-LOC™ Container Security System provides security for containers whether they are being used for shipping or for stationary storage. The HOC-LOC™ Container Lock can be purchased as a stand-alone unit with Power Keypad or can be packaged with the optional GPS Tracking & Control Unit. With the HOC-LOC™ exclusive, Powered Keypad, no internal power source is required. In combination with the GPS Tacking & Control Unit, operation, programming, and event reporting is possible from remote locations with password access from a desktop computer. As with other HOC-LOC™ products, security is enhanced by entry codes generated specifically for each unit.
