The W Alert, which has surpassed a cumulative total of 10,000 units, now adds an AI camera as an optional product! With AI person detection and 360° tag detection, it addresses contact accident prevention!
"W Alert Plus AI" is a contact accident prevention system that adds AI cameras to the worker proximity detection system "W Alert," allowing for the detection of individuals without IC tags. The AI camera located at the rear of the vehicle identifies people and issues an alarm when they approach. By combining 360° detection through magnetic fields and radio waves from IC tags with the AI camera's person detection, it reduces the risk of contact accidents between people and vehicles. It contributes to enhanced safety management in environments such as factories, logistics warehouses, and construction sites where many people come and go. *This product is an optional item for W Alert. The W Alert detection device is required for use. ◇Addressing these issues Measures against contact accidents between forklifts and pedestrians Reduction of near-miss incidents due to blind spots of heavy machinery Safety measures for individuals without tags Setting alarm range according to the site ◇Features ■Detection of individuals without tags The AI camera identifies people and issues an alarm when they approach. ■Detection of people in blind spots Additional camera detection covers areas that are difficult to detect with tags alone. ■Responds only to people, reducing false alarms The AI distinguishes between people and objects, triggering alarms only for individuals. ■Stable detection in dark or backlit conditions Capable of detecting in environments with poor visibility, such as outdoors or inside tunnels. ■Expandable option that can be retrofitted Enhances safety measures simply by adding to existing W Alert systems.
