How an Israeli Technology Became a Game-Changer in Search and Rescue

Developed by Camero-Tech in Israel, the Xaver™ radar family has rapidly become one of the most influential technologies in global search-and-rescue. Its ability to detect human presence, movement, breathing patterns and micro-vital signs behind solid walls and collapsed structures gives rescue teams a decisive advantage during the critical “golden hour.” From major earthquakes to missile strikes, this innovation is redefining the way lifesaving missions are planned and executed.

The morning after the devastating earthquake in Thailand in March 2025, international rescue teams faced a familiar and terrifying uncertainty: were there survivors trapped under the collapsed buildings? Amid the dust and noise, a rescuer approached a shattered wall, placed a compact black device against it, and instantly detected signs of life.

The device was a system developed by Camero-Tech, part of the SK Group. Its breakthrough lies in transforming solid concrete, brick, and debris into “transparent” materials. Using ultra-wideband (UWB) radio waves and proprietary algorithms, the Xaver™ systems interpret returning signals to isolate human movement, even subtle breathing — behind obstructions.

Traditional acoustic sensors often fail in chaotic environments. In contrast, the Xaver™ technology provides a clear, real-time view of what lies beyond the wall, offering rescuers reliable information before making life-risking decisions.

Equally important is its simplicity: operators place the system against a surface, press a single button, and immediately receive intuitive visual data. Advanced models like the Xaver™ 1000 even offer AI-driven 3D visualization of a person’s posture, location, and height, a level of clarity once considered impossible in disaster scenarios.

Today, Camero-Tech systems are deployed worldwide in earthquakes, building collapses, missile impact sites, and urban disaster zones. With tools like XaverNet™, multiple devices can be monitored remotely, improving coordination and safety during critical missions.

This capability to rapidly detect life beneath rubble or behind walls has become essential for overcoming the “golden hour,” where every minute determines survival.
