Feature: 1. HIGH PERFORMANCE: The signal detector has high sensitivity, radio waves, faster search signal, strong anti interference, more accurate unlocking azimuth distance detection. 2. WIDE DETECTION RANGE: The high sensitivity chip increases the exploration range and broadens the exploration frequency, the detection range can reach 10 meters without interference. 3. WIDE APPLICATION: This machine can detect 2G, 3G, 4G and WiFi devices, and can also detect 1.2G, 2.4G, 5.8G wireless cameras, with a wide range of applications. 4. ALUMINUM ALLOY: The aluminum alloy casing is used to effectively dissipate heat and cool down, ensuring long term operation, and the casing can shield the clutter from the chip. 5. MULTIPLE USAGES: Can detect listening devices, illegal devices, etc., effectively protect individual secrecy and confidentiality, and is widely used in conference rooms, hotels and cars, etc. Specification: Item Type: Camera Detector Frequency Range: 1-8000MHz Detection Dynamic Range: >73db Indication Method: 9 level LED indication, pitch change indicator Power Supply: Built in 3.7V 1500mah 803450 polymer lithium battery Working Current: 60mA Continuous Work: 10-15 hours Detection Sensitivity: <0.03mw Detection Range: 2.4G: 15m² (standard 10MW) 1.2G: 10m² (standard 10MW) Mobile Phone Signal 2G 3G 4G: 10m² Material: ABS, Aluminum Alloy.
