V prípade, že je miniatúrna kamera s pinhole objektívom správne ukrytá, je takmer nemožné ju odhaliť. A ak je vyriešené napájanie, môže byť v záujmovom priestore aj niekoľko mesiacov, alebo rokov. Klasické rádiové detektory odhalia len bezdrôtové kamery. Ale čo v prípade, že bude použitá káblová kamera, alebo bude zapnutie a vypnutie bezdrôtovej kamery ovládané na diaľku? Detektor kamerových objektívov odhaľuje objektívy, tzn. je jedno či je kamera aktívna, alebo neaktívna.

Professional Handheld Simple Spectrum Analyzer 35MHz ~ 4400MHz Big LCD Screen Wireless Signal Detector for Radio / WiFi / GSM / Walkie-Talkie and Camera Search Full-Range RF Detector Communications Parts

Product Description:

Professional Spectrum Analyzer used by e-exterminators for quick seach many kinds of audio bug, car tracker, wireless pinhole camera, mobile phone, or any another hidden wirelles equipments. Product is easy to use, trustworthy and quickly ready to use, meet surveillance standards.
AirBnB accommodation, hotel rooms, fitness locker room, swiming pool locker room, shopping mall fit room, and many another places should be check by yourself before use. Your car you should check routinely once a week.

Note

On display you can see max. 350 MHz wide span ( cannot see full range from 35MHz to 4400MHz at same time).
For exsample you can set 350MHz wide span as :
35 MHz ~ 385MHz – mostly used by VHF walkie-talkie
385 MHz ~ 735 MHz – mostly used by UHF walkie-talkie, remote control 433MHz, and 4G network
735 MHz ~ 1085 MHz – mostly used by 2G GSM and remote control 868MHz
1085 MHz ~ 1435 MHz – mostly used by 1.2 GHz wireless cameras
1435 MHz ~ 1785 MHz – mostly used by GPS Jammer 1575 MHz
1785 MHz ~ 2135 MHz – mostly used by 2G GSM and 3G
2135 MHz ~ 2485 MHz – mostly used by WiFi equipments (camera, router, signal extender, printer, … etc.)
2485 MHz ~ 2835 MHz – mostly used by 4G network
2835 MHz ~ 3185 MHz
3185 MHz ~ 3535 MHz
3535 MHz ~ 3885 MHz
3885 MHz ~ 4235 MHz
4235 MHz ~ 4400 MHzWith narrow span you can measure more precise and don’t miss any signal.( sure, you can set your own frequency 350 MHz wide span )

Note:

1. This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high accuracy VCO source, the heterodyne signal frequency can be measured very accurately. Since the scanning range is very large (35MHz-4400MHz), because there is no special detection circuit for the external measurement signal due to cost and other factors, the measurement amplitude may have errors. Therefore, the product increases the magnification and displacement parameters, and the user can adjust the display waveform by himself. The amplitude display is adjusted and calibrated.

2. Internally integrated lithium battery charging circuit, due to logistics safety reasons, this product is shipped without battery. By default, USB is used to supply power. Customers can add lithium batteries by themselves.This product (pictures and text) is from Aliexpress iCareStore store (910322024), if you see this mesage in another shop, it mean they copy us without thinking, and even withoutreading.
