A long-distance remote control to ensure safety in emergencies.

In the security industry, a rapid response during emergencies is required. In particular, the remote operation of emergency buttons is a crucial factor that affects the reliability of security systems. Wired systems may face challenges due to wiring work and installation location constraints. Our 426MHz band 2-button specific low-power wireless remote control enhances the flexibility of emergency button installation locations and enables a quick response during emergencies, thanks to its long-distance communication of over 200 meters in line of sight and easy installation without the need for a license. 【Usage Scenarios】 * Emergency buttons in commercial facilities and office buildings * Communication during emergencies in parking lots and bicycle parking areas * Portable emergency buttons for security personnel 【Benefits of Implementation】 * Rapid response to emergencies * Increased flexibility in installation locations * Reduction in wiring construction costs

Applications/Examples of results

【Purpose】 Two-system ON/OFF operation to enhance safety and efficiency on site. It can be used for remote control in situations where two actions need to be individually controlled, such as opening and closing or stopping (e.g., electric shutters), or ON/OFF and alarms (e.g., equipment startup and buzzers). It helps address more advanced remote operation needs, such as complex equipment control in factories and facilities, and multifunctional safety measures at construction sites.
