Signal Detector Infrared Camera GPS Checker MultiFunction for Bathroom Hotel Office Item Type: Signal Detector Material: Aluminium alloy Uses: Washroom, office, hotel, motel, conference room or home use Radiofrequency Frequency Detection Range: 10 - 3000MHz RF Signal Detection Distance: (Depending on the signal strength of the source) GSM: Approx. 50 - 300cm/1.6 - 9.8ft 3G and 4G: Approx. 20 - 100cm/0.7 - 3.3ft WIFI: Approx. 10 - 100cm/0.3 - 3.3ft Infrared Detection Frequency Range: 750 - 1000nm Infrared Detection Range: Approx. 1 - 10m3.3 - /32.8ft (depending on signal intensity of light source) Laser Indicator Power: Class 11 1mw Observation Eyepiece Magnification: 5 Optical magnification Battery: 3.7V lithium battery 500 mAh (battery included)Charging Port: Type-C Charging Voltage: DC 5V 1A Built-in Battery Life: More than 12 hours Instructions: Boot up Turn the knob on the top of the detector clockwise to turn it on, and the product is in electromagnetic wave detection mode by default when it is turned on. 1. Electromagnetic wave detection mode The detector comes with a radio frequency (RF) detection antenna. When the electromagnetic wave signal emitted by the target device is detected, the signal strength indicator on the device panel will indicate the signal strength, and the built-in buzzer will give a sound prompt. The radio frequency signal detection sensitivity of the detector can be adjusted through the knob on the top. The default sensitivity is the lowest when it is turned on. Continue to turn clockwise to increase the sensitivity. When the first signal light of the radio frequency level indicator is on, the sensitivity is at the highest state, and the detection locator/ Generally, a medium sensitivity is sufficient for a wiretap, and a higher sensitivity is required to detect a WIFI camera. 2. Optical lens detection mode First turn on the power of the detector, and then press the panel to press the 5 key. The beam transmitter of the detector will emit a beam of special wavelength and frequency. The user holds the detector and the eye is close to the eyepiece for observation. When the beam emitted by the transmitter is irradiated When it comes to the optical lens of the detected camera, since the first piece of the camera's optical lens objective is basically a convex lens, the convex lens will focus and reflect the incident light emitted by the detector, and the reflected light will be reflected to the light source at a 180 degree angle. In the observation eyepiece installed behind the launch point, the light enters the 5x optical magnification through the objective lens, and finally is projected on the observer's eyes through the eyepiece lens to form an image. The observer can clearly see the lens of the detected camera through the eyepiece. The light spot with a frequency of 1.6 Hz flickers, and then you can further investigate whether there is a miniature camera installed at the flicker of the light spot. 3. Infrared detection mode Short press the panel button speaker on/off key to turn on and off the detection alarm sound, long press the button for two seconds to switch the device from detecting radio frequency mode to detecting infrared mode. When the device is in infrared detection mode, the laser pointer on the front panel of the detector is turned on, and the infrared detection sensor on the front of the panel is in the receiving state. The user holds the detector to detect and scan the environment. When the infrared detector detects that the environment exceeds the setting When the intensity value is infrared, the detector will send out an audible and visual alarm, and the laser pointer will indicate the specific installation location of the infrared emission source, so that the user can easily find the target device to be detected.
