8 high-brightness infrared LEDs: Using LED infrared physical laser scanning technology, the detector emits infrared rays, and through the dual effects of refraction of the camera glass mirror and filtering of complex light by the color filter, the hidden camera is scanned Narrowband filter: 625NM narrowband filter can effectively enhance the naked eye inspection effect, enhance the reflection effect of the camera lens, and allow you to quickly check the hidden camera Small and portable: Small size and lightweight, easy to put in your pocket or luggage for travel Ultra-long battery life: Ultra-low power consumption, standby for 70 days, can be used continuously for 20 hours Function: Press the button for 2 seconds to turn on the device. After turning on, it will enter the "wireless signal detection" mode by default. When there is no signal, the red light will be on; when a signal is detected, a beeping alarm will sound Press the button again, a "beep" sound will be heard, and it will enter the "infrared scanning detection" mode. The 8 red lights on the back will flash, and the lens will look for the bright spot of the lens reflection through the lens to detect the camera Press the button again, "beep" twice, and it will enter the vibration anti-theft mode. After detecting vibration, an audible and visual alarm will be sounded Press the button for 2 seconds to turn off the device Specifications: LED lamp beads: 8 high-brightness infrared fill lights Lens material: 625 narrow-band infrared filter lens Charging interface: Type-C Continuous use time: 20 hours Battery capacity: 140mAh Charging time: 1 hour
