LCD Mobile phone detector - SH-055UAxx series


There are many wireless products nowadays, and the air is full of radio waves of various frequencies, especially WiFi everywhere. Most of the so-called full-featured detector responds to all kinds of radio waves but fail to indicate the signal type that general consumers will panic about too many alerts.

We develop SH-055UA especially to detect the 2G-3G-4G-5G radio waves of mobile phones. It does not interfere with the radio waves of other frequency bands than mobile phones.  It has a clear screen display and simple & easy operation. Both professionals and ordinary users can smoothly check whether someone is using a mobile phone.


SH-055UA has the following features:

1. DETECT 5G sub 6 FREQUENCY BAND: It has good detection capability for 5G sub 6 3300 ~ 3650 MHz. 



2. THREE SENSITIVITY BENCHMARKS: SH-055UA has Low-Medium-High three benchmarks, user can set the sensitivity benchmark according to the range to be detected.

For example, to detect a big room or a high ceiling room, set the benchmark at High can get a detection distance up to 20 meters radius.

To detect a small area, such as a prison cell, set the benchmark at Low can get a detection distance up to 5 ~ 6 meters radius. Then it is not easy to detect the radio waves from the next room.


3. TEN SENSITIVITY LEVELS: Each of the three benchmarks has ten sensitivity levels for users fine-tuning the detection distance. When detected mobile phone signals, lower the sensitivity gradually to get closer to the signal source.


4. CLEAR DISPLAY: When detected mobile phone radio wave, the LCD screen will display the frequency band, the signal strength (dB value), and bars of signal strength. Both ordinary users and professionals can
know the result immediately.


5. FOUR WARNING MODES: It has Beep, Vibration, Beep + Vibration, and Silent for selection. If set warning mode to Silent, plug in the earphone to detect by listening.

SH-055UEMR+ Enhanced All-in-one hidden camera detector

SH-055U8LN+ and SH-055U8LNW+ have TWO major upgrades

1. SH-055U8LN+ & SH-055U8LNW+ apply with new IC to enhance the display
   of digital signal. It can detect 1mW 2.4G WiFi IP camera in 2 meters
   with very clear LED indication.

   SH-055U8LN+ & SH-055U8LNW+ also greatly improve the detection distance
   of other digital signals, such as 30% longer for 2.4G WiFi and 130%
   longer for 4G 1800.

2. Added charging LED display to show the charging status.

SH-055UOF Power off phone DETECTOR nice for entry inspection



Everyone knows that mobile phones now are used not only for phone calls,
but most for many jobs through internet. 4G and 5G provide
higher and higher transmission speeds, sending large amounts of data in a second.

Protection for valuable information, commercial and industrial secrets
of government, military, factories and enterprises become major
security issues. Therefore, mobile phones are not allowed in many

SH-055UOF can detect mobile phones that have been turned off, removed
battery, removed SIM card or set in airplane mode. It is the best
HANDHELD tool for security guard to check if the entry person is
