Dynamic Systems developed the CheckMate Equipment Manager software to help law enforcement agencies track equipment check-outs and reduce loss of gear. The software uses barcode technology to track who checked out equipment, when it is due back, and whether it needs maintenance. It can also track inventory levels of consumables. Wilcox Industries' Mission Helmet Recordable System integrates a night and day camera recorder with an 8GB hard drive to record up to eight hours of high-resolution video and audio. The system is mounted to a helmet and all controls are located on the recorder module at the back of the helmet. Data can be easily downloaded from the system to a computer.
