When it comes to signal detectors, one can't help but think of hidden cameras, secret cameras and monitors, etc. These cameras, whose locations are unknown, might be secretly photographed while staying in a hotel or changing clothes in a fitting room, making it hard to guard against them. Now, let's analyze the working principle of the wireless signal detector for everyone to understand.
First, communication signal detection
The wireless signal detector is first capable of detecting communication signals from all frequency bands of 2/3/4/5G operators, including China Mobile, China Unicom, China Telecom and China Broadcasting Network. It utilizes the built-in spectrum analysis technology to scan and analyze commonly used communication frequency bands such as 315-433M, 800M, 1.2G, 1.4G, 2.4G, 5.2G, and 5.8G. By capturing effective signals in real time and supporting external antennas to enhance detection accuracy, wireless signal detectors can quickly locate communication signal sources within the area.
Second, WIFI scanning and positioning
For WIFI signals, the wireless signal detector can cover domestic 2.4G/5.8G wireless access points and wireless terminal devices. It supports multiple WIFI protocols such as 802.11a/b/g/n/ac/ax, and is capable of scanning WIFI hotspot information (including hidden WIFI hotspots) and WIFI terminal information (including terminals with and without connected aps). By collecting this information, the wireless signal detector can precisely locate the designated WIFI access point or terminal target.
Fourth, wireless spectrum detection
The wireless spectrum detection function of the wireless signal detector covers a wide frequency band range of 1Mhz to 12G, and is capable of detecting signals within most communication frequency bands at home and abroad. It supports demodulation of specified suspected FM/AM signals to restore sound playback, and can clearly display wireless spectrum images through an 8-inch high-definition all-in-one touch screen. In addition, the wireless signal detector also supports the recording, comparison and positioning functions of wireless spectrum signals, providing users with rich spectrum analysis methods.
Fifth, Comprehensive application and early warning search
Wireless signal detectors perform well in comprehensive applications. It can not only capture and locate communication signals, WIFI signals and Bluetooth signals in real time, but also issue early warnings and search for potential security hazards such as suspected GPS trackers, WiFi/FM eavesdroppers, Bluetooth trackers and WiFi pinhole cameras within the area. These functions make wireless signal detectors have extensive application value in scenarios where there are potential security risks in the wireless environment, such as military industry, government, banking and finance, business travel hotels, private residences, and special vehicles.
In summary, the working principle of a wireless signal detector is to conduct comprehensive detection and analysis of communication signals, WIFI signals, Bluetooth signals, and wireless spectra through multiple built-in detection technologies and functional modules, thereby achieving early warning, detection, and precise location of potential safety hazards.
