Mitsubishi Electric Develops Multihop Wireless Network for Surveillance Cameras

Instant implementation simply by adding wireless cameras to WLAN using visualization software

TOKYO, January 28, 2015 - Mitsubishi Electric Corporation (TOKYO: 6503) 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.

Surveillance cameras with wireless LAN function capability are commercially available, they require an AC power supply. A wired LAN and routing equipment are also required to network multiple cameras.

Mitsubishi Electric's new system, however, 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.

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. Even non-technical persons can build and operate a network.

The demand is rising for surveillance camera networks, including for one-time events such as marathons or outdoor concerts, to ensure safety and security. Mitsubishi Electric's new wireless surveillance camera network is expected to help meet this demand by reducing installation costs and labor. The system can also be used to complement existing wired LAN-based surveillance camera networks.
