Mitsubishi Electric Develops Multihop Wireless Network for Surveillance Cameras
Mitsubishi Electric has developed a wireless network system for surveillance cameras that uses multihop technology to enable users to set up a network simply by connecting the wireless cameras using visualization software, without any need for power cords or a wired LAN. Commercially available surveillance cameras with wireless LAN function capability require an AC power supply. A wired LAN and routing equipment is also required to network multiple cameras. Mitsubishi Electric’s visualization software is a simple user interface for monitoring the wireless channels. It instantly visualizes signal conditions and possible breakdown locations to enable users to find the best locations for installing cameras.
Mitsubishi Electric’s new system uses multihop technology to transmit the video images via a bucket relay system, eliminating the need for a wired LAN or routing equipment. In addition, the cameras are battery-powered for easy, flexible installation. Reliability is enhanced by monitoring the wireless channels’ status to control data volume and thereby reduce possible interruptions. Even non-technical persons can build and operate a network.
