Power on Self-test Wireless Signal Detector with Strong Signal Warning




Power-on self-test, intelligent display of all working status, including charging and alarm status and signal CAM/BUG/LTE

Distinguished from the Wifi signal. A reliable default benchmark for sensitivity. 8 LED signal strength. Two alarm modes and a strong signal red light alarm. Automatically indicates the signal category. Professional 3G testing. The detection of the mobile phone in the standby state effectively recognizes the WIFI hidden camera and supports the charging treasure. With LENS finder - detection for wired cameras. With the directional antenna, according to the reduction of the detection range, the range of the range of the antenna detection is gradually reduced. Although it is mainly aimed at sneak shots, it also has a good effect on the 2g3g4g bugs of mobile phones.



  1. Power-On Self-Tes

Every time this device is switched on, this device will do power-on self-test of all functions and all the LEDs of this device will be lit up.

Then the 8 signal strength indication LEDs will be put out one-by-one, from 8 7 6 … to 0. The 7-segement LED also shows 8 7 6 … to 0 synchronously.

1 Power Switch on
2 Vibration Vibration warning mode (manual shift)
3 Beep Beep sound warning mode (Default)
4 Hi Signal Warning of strong signal in around
5 CAM / Bug / LTE

Analog / Spread spectrum signal of

Camera, bug and cellphone

6 WiFi Digital signal of WiFi and IP camera
7 Battery low Battery power running down
8 Charging Status of battery charging



After this device finished its self test, the sensitivity will stay at factory default benchmark of “Level 8” and the digit display shows 8, this is default sensitivity benchmark.

The default benchmark is one of our core technology, can fit for different environments all over the world. If this device beeps or vibrates and some of the LED light up, it means that there should be some wireless signals or environment noises around.


The 8-LED bar will light up according to the signal strength from low to high, green à yellow à red, higher signal, more LED.


Vibration/Beep (Default)

  1. Strong signal warning (Hi Signal)
If there is strong signal around, user needs to lower the sensitivity in the 2nd stage, the Hi Signal warning will light up in red to alert the user.

This device will indicate detected signal automatically.

CAM / BUG / LTE : Analog and Spread spectrum signals of wireless camera, wireless bug, signal jammer and 2G / 3G / 4G cell phones, etc..

WiFi: Digital signals of WiFi, IP camera, wireless digital camera, etc.

1)Battery&Charging Status

Battery Low : Warning of battery power running down.

2)Charging: Indicate the status of battery charging. When starts charging, indication lights up in red as quick charging, when charging to about 70%, it will change to slow charging, the indication shift to green.


This device applies advanced technology of digital sensitivity adjustment. Press once the "- (minus) button", located at the left side of front view, can lower sensitivity one level, the detecting distance will become shorter, This function is nice for finding the location of signal source.

  1. This device applies unique technology of 2 stages digital sensitivity adjustment to catch weak and strong signal no matter in quiet and noisy place.
  2. Usually, high sensitivity device will detect strong signal in longer distance away, but could not approach to find the signal source. Or just be interfered with the strong environment noise, so as TV station, cell phone tower, cell phone signal booster, etc. will emit strong signals, common detectors will be affected by those strong noise and become blind.
  3. And most detectors in market just with low sensitivity can detect small signal, so as 3G 2100, in only few inches or even no response.
  4. In the first stage, the super high sensitivity of this device can detect 10mW 2.4GHz wireless signal or 3G 2100 signal (both are weak signal) up to 7 meters (21 feet). The sensitivity has 9 levels, from 9 to 1, suitable for normal environment.
  5. The second stage of this device has big tolerance to eliminate the interference and to find the strong signal source. This device can approach two watt (2W) transmitter in about 2 feet (0.6 meter), none can compare with.


3G 2100 is the most popular cell network, including voice and data communication. In many countries, cellphone will shift to 3G 2100 automatically when signal of 4G network is poor.

This device has an individual 3G 2100 detector module which has excellent detecting ability, none can compare with.


This device can detect and locate new bug (active transmitting hidden microphone) and active transmitting spy camera remote controlled by cellphone.
