The G638 is a highly sensitive, digitally controlled device for detecting wireless signals between 300-2700 MHz. Compact and easy to use, it features audible and vibration alarms, and a 10-level LED sensitivity indicator to accurately identify signal strength. Capable of detecting 2G, 3G, 4G signals, wireless cameras (1.2G/2.4G & 5.8G), GPS trackers, bugs, and hidden cameras, the G638 effectively locates concealed spy equipment in rooms, cars, hotels, conference rooms, and other private areas. Its infrared camera detector quickly identifies hidden lenses via optical reflections.
