The invention relates to security equipment and a system of a container, which comprise a monitoring and calculating platform and a monitoring system, wherein the monitoring and calculating platform is installed in the container, and the monitoring system is arranged at a detection unit of the container and is based on a PC. The monitoring and calculating platform comprises a mainframe box of thecalculating platform, a power controller, an external battery, a camera, a visible light sensor, a box door switch sensor and a GPS antenna, wherein the mainframe box of the calculating platform is provided with an electronic circuit board and a mass memory; and the monitoring system based on the PC comprises a high-speed PC, a standard external bus interface, a character processing module and animage processing module, wherein the high-speed PC can directly drive at least two displays. In the invention, the monitoring and calculating platform is part of a container body, the cost proportionoccupied by the monitoring and calculating platform is very low, the transportation cost can not be increased after the monitoring and calculating platform is distributed in a multi-time transportation process, and the monitoring system based on the PC takes the automatic operation as a main part, only can increase the clearance efficiency and does not need to increase the manpower allocation.
