Mitsubishi Electric Corp. said it has developed a wireless network system for surveillance cameras that uses multihop technology, allowing users to set up a network by connecting the wireless cameras using visualization software without the need for power cords or a wired LAN.
Surveillance cameras with wireless LAN function capability are commercially available that 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, negating the need for a wired LAN or routing equipment, according to a press release. In addition, the cameras are battery-powered for more flexible installation. Reliability is enhanced by monitoring the wireless channels’ status to control data volume and thereby reduce possible interruptions, the company stated.
Mitsubishi Electric’s visualization software provides a 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.
The demand is rising for surveillance camera networks, including for one-time events such as marathons or outdoor concerts to ensure safety and security, the press release states. The company expects its new wireless surveillance camera network will 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.
