Can detect wireless lenses through the wireless frequency detection function It is difficult to detect various lenses with the naked eye by scanning the red highlight light The detection frequency range can reach 1MHz-6.5GHz Can effectively detect wireless and wired cameras Wireless detection multiple prompt functions: sound prompt, vibration prompt, LED indicator light prompt Headphones can be connected to detect in a more stealthy way Wireless signal strength indicator, quickly locate the signal source Detection sensitivity can be adjusted Built-in rechargeable lithium battery. Can be used continuously for 5 hours Very small size, very convenient to carry around Applications: Detect whether your car has been installed GPS tracking eavesdropper, GPS location tracker. Visible scanning CCD and CMOS lenses include wired and wireless, including mobile phone lenses, digital cameras, cameras and other imaging equipment, and also have high-sensitivity detection functions for long-distance monitoring voice equipment based on GSM signals; Simple operation, green environmental protection equipment, no negative impact on people and things Exquisite appearance, aluminum alloy shell, small size, light weight, easy to carry There is a small compass under the front of the product, with a blue light background, which is convenient for indicating the direction and is suitable for professionals; Built-in rechargeable lithium battery. Can be used continuously for about 5 hours Small size and light weight: 1) There is no remote signal; refer to the instructions for its application. 2) There is a signal from a distant place; Judgment method: pull out all the antennas, move the handheld detector, and there will be vibration, light or sound prompts, please adjust the length of the antenna until there is only one antenna left (detection sensitivity is related to the distance from the source and the length of the antenna) related), if there is the same prompt at two or more places in the space with a distance of more than 3 meters, and the closer to the window, the more obvious the vibration, it can be confirmed that it is a signal from a distant place. In such an environment, the application method of V120 is as follows: 1) Take back all the antennas. At this time, the prompts of the detector are limited to the prompts within 50 cm of the emission source, and the interference of distant signals will be automatically eliminated. Please retract the antenna and hold the detector. The camera and camera that are most easily hidden in the space The position of the earphone is close to the motion detection to ensure safety. 2) In this kind of space with external signal distribution, to beware of outsiders and objects, please switch to the vibration gear, put it in your pocket, walk by the outsider or approach the object, and you can use the vibration perception. 3) Strict distinction between mobile phone signal and other signals is the biggest feature of this machine. When the user is using the mobile phone to prevent bad applications, there is no need to move, as long as the detector is turned on, there will be a light (vibration file) or light + sound prompt. One situation is that users arrive at non-recurring and uncertain places and spaces, such as hotel rooms, karaoke or massage rooms, consumption places, tea bar talks and other places. Since there is no opportunity to do background detection, users should use it correctly according to their needs. 1) If you are concerned that the content of the conversation is leaked through the mobile phone terminal, please turn on the antenna of the device and it only needs one length. If there is no light flashing, it means that there is no mobile phone in working condition, or there is no environmental monitoring device based on GSM network technology. 2) If guest rooms or massage rooms have time and space to complete the use of fixed places, please follow the method of using fixed places. 3) If there is no space and time precautions, please walk around the interviewers and tables for a week without using the antenna (the antenna is fully retracted). If there is a vibration prompt, it means that there is a wireless or listening device working. To ensure safety , please pull out a section of the antenna, repeat the above method again, if prompted, please change the meeting place
