Function:This product adopts the method of passive wireless frequency scanning; which can accurately find out: eavesdropping device phone eavesdropping; digital eavesdropping; tracking device; car eavesdropping; wireless pinhole camera; wired camera; electrical radiation source; etc. It can effectively prevent eavesdropping; take pictures; cheat; and protect personal privacy and information confidentiality. &nbsp;Feature:1. Anti-Spy; Anti-eavesdropping; Anti-Tracking Detector Pen&nbsp;2. Small Portable Size&nbsp;3. with automatic detection function; portable host to easy carry. When there is eavesdropping device; pinhole camera; casino fraud; the detector will automatically alert you of the danger.&nbsp;4. With 6 signal strength indicating light; can adjust the sensitivity of the device; quickly find the source of the signal.&nbsp;5. The sensitivity can be adjusted by adjusting the potentiometer. (increase the sensitivity to expand the detection range or decrease the sensitivity to shorten the detection range to find the source of the wave faster)&nbsp;6. Multiple detection mode: 1. Laser detection; 2. Vibration (silent) detection; 3. Beeping detection; 4.LED signal display detection. 5. Headset: connect to the headset to realize silent detection.&nbsp;7. Wifi detect: detect wireless hidden camera; Radio wave (wireless camera/bug); Full-band Full band detection;&nbsp;8. low voltage prompt function; built-in rechargeable battery.&nbsp;Parameter:Product Size: 16*103mmProduct Weight: about 30gCharging Interface: Type-CAntenna: SMA interface AntennaAntenna Gain: -14dbPower Supply: DC5V/1ABattery: 3.7V/350mA Polymer lithium batterySensitivity: 5 levelsReceiving frequency range: 1MHz-6.5GHzSignal Detection range: 5 cm~10 meterOptical lens: Special filtersLaser detection range: 10 cm~15 Meter &nbsp;Package Include:1 x Detector1 x USB cable1 x User Manual (English) &nbsp;<img data-srcid="-" src="https://image.doba.com/dgd1-VcvWzNOGTPqL/wt09-2020-new-rf-wireless-signal-detector-pen.jpg" alt="dropship WT09 2020 New RF Wireless Signal Detector Pen" /><img data-srcid="-" src="https://image.doba.com/dgd1-VRqDydpSTcvL/wt09-2020-new-rf-wireless-signal-detector-pen.jpg" alt="dropship WT09 2020 New RF Wireless Signal Detector Pen" /><img data-srcid="-" src="https://image.doba.com/dgd1-vuVYylOcaoqs/wt09-2020-new-rf-wireless-signal-detector-pen.jpg" alt="dropship WT09 2020 New RF Wireless Signal Detector Pen" /><img data-srcid="-" src="https://image.doba.com/dgd1-VgqPydOGTJbw/wt09-2020-new-rf-wireless-signal-detector-pen.jpg" alt="dropship WT09 2020 New RF Wireless Signal Detector Pen" /><img data-srcid="-" src="https://image.doba.com/dgd1-VTbdiSuKtYDs/wt09-2020-new-rf-wireless-signal-detector-pen.jpg" alt="dropship WT09 2020 New RF Wireless Signal Detector Pen" />
