Broadband Field Strength Meter RF Field Intensity Anti-GPS Positioning Detector
Description:
This detector is suitable for detecting radio waves of 20MHz-6.5GHz. Sensitivity is very high, and it is adjustable. It can detect weak signals of mw level (General household wireless routers, wireless AP WIFI signal power is about 35mw) and detect suspicious radio wave signal. According to TV reports, some criminals have installed wiretapping or video recording equipment in hotels, and personal information is transmitted to them via wireless signals. So we can use this to detect if there is a suspicious signal in a room when we check into a hotel. Test method: Adjust the sensitivity to a suitable position, for example, when the needle is in the middle position, hold the detector and walk around the room to see the movement of the needle. If the hand of the watch suddenly swings a lot when you go to a certain place, it means that there may be a wireless transmitting device this time, and you can find the position of the transmitting source closer here (the closer to the transmitting source, the greater the swing of the hands).
The same method can detect whether your living environment, meeting room, or even a more confidential place is installed with a detectophone, or wireless camera equipment.
If your phone is wiretapped or even installed with wiretap software, or even your phone camera will be turned on automatically, so your secrets will not be kept. However, the information obtained above must be transmitted wirelessly, so you can use this detector to detect whether your mobile phone is transmitting signals, and thus you can determine whether there are illegal signals. Test method: Place the detector close to your mobile phone and observe the detector quietly. If the mobile phone does not receive any text messages or calls, and when the mobile phone’s wireless data network and wireless WIFI are turned off, it transmits signals outside for no reason, indicating that there is a problem with the mobile phone. (Of course, mobile phone will occasionally contact the base station for wireless data communication, this is a normal situation. The premise is that this happens occasionally. For static and small moving distances, it will take a long time for the mobile phone to contact the base station).
When you buy a second-hand car, if the car has been mortgaged, or the car has been installed with a GPS locator, then you need to use this detector to check. Test method: Adjust the sensitivity of the detector, for example, adjust the needle to the middle position, put the detector on the dashboard in the cab, and observe the movement of the needle quietly. If the hand of the watch suddenly swings sharply several times every few minutes, it means that the car has been installed with a wireless GPS locator. If you want to further find the installation location of the locator, you need to move detector to see where the swing amplitude is the largest, which means that the GPS locator is at that place. The premise is to keep the mobile phone away from the detector to avoid interference detection. Some GPS locators transmit position signals about once every 1-2 minutes, and some may only transmit position signals once every 5 minutes.
For different signals, the detector has different detection distances, which are mainly related to the transmission power of the transmitter. For general home wireless routers, WIFI signals, and wireless AP signals, the detection distance is about 1-2m/3.3-6.6ft. For GSM mobile phone signals, the detection distance is about 1-2m/3.3-6.6ft (mainly based on the distance between the mobile phone and the base station. If your mobile phone is far away from the base station, then the transmission power of the mobile phone will be large, and the detection distance will be far, and vice versa). For CDMA mobile phone signals including CDMA wireless GPS locator, the detection distance is about 10-30cm/3.9-11.8 inch.
Designed with built-in 9V laminated battery (square battery) (non-rechargeable).
The above is just a brief description of its uses. More flexible uses are waiting for you to explore.
