The San Mateo County (Calif.) Sheriff's Department has deployed an outdoor wireless network-based video surveillance system in preparation for the Scott Peterson trial that started June 1. The project is a team effort between Tropos Networks, a supplier of equipment used to build metro-scale Wi-Fi networks, On-Net Surveillance Systems, a developer of network-based digital video surveillance solutions, and Sony Electronics, which provides video surveillance cameras. The system will provide real-time video surveillance and recording of public areas at the San Mateo County Center for the duration of the trial.
