This device (#Versatile RF Signal Detector #WiFi IP Camera Detector #Cellphone Detector #Anti-Camera Solution #Counter Surveillance #GSM GPS tracker DETECTOR #RF Bug Sweeper) is a VERSATILE RF signal detector which can detect most of GSM phone, 3G/4G smartphone, WiFi, GSM GPS tracker, Wireless and other wireless device during 50 MHz ~ 6.0 GHz.

1. Wide Detect Frequency Range: 50 MHz ~ 6.0 GHz, including 2G_4G_5G smartphone, WiFi, wireless bug (hidden microphone), wireless  analog cameras, digital cameras, IP camera and other wireless device  during 50 MHz ~ 6.0 GHz.

2. SEMI DIRECTIONAL ANTENNA: This feature is very helpful in locating  the signal source. When reducing the sensitivity to approach the  signal source, the scan angle is also changing from wide to narrow.

3. Foolproof indication : 8 levels signal strength indication

4. Digital signal amplifier

5. Earphone for silent detection

6. Sensitivity tuner for distance adjustment and environment noise   elimination.

7. Standby / Idle phone registration detection

8. SH-055NV is also good in detecting SMS (Short Message Service) signal from GPS tracking devices. But, SH-055NV does not have the special filter as SH-055SDV, so it will beep or vibrate with all kinds of analog & digital signals. User is not easy to identify the SMS signal of GPS tracker.

• Standby / Idle Phone Registration Detection

If a smartphone is in standby mode, this device may trigger intermittently. This happens as mobile phones stay connected to the base station, receiving signals for automatic re-registration with base station. The registration interval and frequency vary among networks and cell phones.

If the smartphone is in airplane mode or powered off, it remains inactive, and the SH-055NV stays silent.
