Many municipalities are turning to mobile computing and other networked applications to improve the efficiency of their workforce, including public safety personnel and first responders. Consequently, public safety workers are increasingly being equipped with wireless laptops, handheld computers, and mobile video cameras to improve their efficiency, visibility, and ability to instantly collaborate with central command, coworkers and other agencies. Video surveillance cameras and unattended sensors are becoming important tools to extend the eyes and ears of public safety agencies.
