Wireless networks are making it simpler for police to preserve order when large crowds gather at events like Super Bowl XLII and the NASCAR Sprint Cup Series. The Glendale Police Dept. monitored activity at both using a video surveillance system from AgileMesh tied together by a wireless mesh network from Firetide. Officers can control the camera, which offers full pan and tilt and a 23x optical-zoom lens. Two levels of encryption ensure security. The mesh network makes it simple to put cameras where they're needed to monitor crowds and people in out-of-the-way areas.
