3-in-1 multi-purpose RF detector and anti-surveillance tool provide 3 functions to search and find devices: RF signal detection to search for wireless monitoring signals,magnetic field detection to locate magnetic GPS trackers,and hidden camera lens finder to discover hidden wired or wireless camera. •It can detect radio waves and magnetic fields •It can detect hidden wired or wireless cameras •Can detect 2G/3G/4G mobile phone SIM card,GPS locator •Can detect 1.2GHz/2.4GHz/5.8GHz wireless hidden cameras,pinhole cameras,spy cameras,webcams,webcams,monitors,microphones,eavesdropping equipment,surveillance equipment •It is also equipped with a magnetic field probe,which can be used to detect backup magnetic GPS locators,GPS trackers,and hidden audio or video devices that are magnetically installed in hidden parts of the vehicle •It can also detect electromagnetic radiation leakage from microwaves •Stylish design. A sensitivity knob and 2 buttons make it easy to use •Adjustable sensitivity. You can adjust the sensitivity up or down according to the detection range required by the environment. When the sensitivity is high,the detection range will be wider and it can capture long-distance radio frequency signals. At low sensitivity,the detection range will be shorter to accurately locate the location of the RF source. You can manually and easily reduce the sensitivity to the narrow detection field where the RF source needs to be locked during the RF detection process •Light alarm function. The color LED indicates the strength of the detection signal,which is divided into 10 levels,green (level 1 to 4),yellow (level 5 to 7) and red (level 8 to 10),respectively representing green for low signal strength and yellow for medium signal Strength,red is the highest signal strength (lock signal source). The closer you are to the signal source,the higher the signal strength displayed on the indicator •Sound and vibration alert. When the signal strength reaches level 7,it will automatically beep or vibrate,and eventually become an uninterrupted alarm when the radio frequency source is locked. The audible alarm is loud enough. When you need to detect carefully without attracting the attention of others,the vibrating alarm is your better choice •Lithium polymer rechargeable battery. Excellent battery life: continuous work for 5-8 hours,standby mode can last for several months. No need to worry about frequent battery replacement or battery charging •Small in size and light in weight,it can be carried in a briefcase,travel bag or suitcase Specification: •Product size: 10.2*5.5*2.1 cm •Weight: 95g •Antenna: Booster antenna •Antenna gain: -14db •Power plug: DC 5V/1A •Battery: Built-in 1000mAh polymer battery •Frequency range: 1MHz-6.5GHz •Signal detection range: 2.4G: 10m²/1.2G: 15m² (mobile phone signal) •Optical lens: Special dedicated filters •Laser detection distance: 10cm-15m •Material: PC Package included: •1 x RF Detector •1 x RF Antenna •1 x GS Probe for Magnetic Field Detection •1 x US Plug Charger •1 x English User Manual
