STACKRACK offers Cloud12, a ruggedized mission critical panel computer, which can be integrated with different types of sensors: High resolution Wide-angle video camera, Forward and Rear looking infrared camera, Crosswind sensor…etc. Despite camera and video distribution system running from day to night, 24hrs, Cloud12 is able to handle with heavy data transmission under high temperature environment while maintaining high-computing performance. For Intel® Xeon E3-1505L V5 processor, it can run full speed without throttling up to 40oC. Also, we adopt NVIDIA Geforce GTX1050 graphic card that performs remarkable image processing and visual displays. To simultaneously connect, receive, and process information efficiently, a computer with CPUGPU structure is needed. Cloud12 can be applied in both land vehicles and naval vessels. It supports soldiers and operators to take immediate and accurate action in every mission, meeting the requirement of situational awareness in real time.
