LED Lamp Beads: The combined size of LED infrared scanning lamp beads makes the light stronger and the scanning distance longer.Highly sensitive chip: increase scanning range, widen scanning frequency, can detect wireless devices between 1MHZ-6.5GHZ frequency.Filter lens: In combination with the filter lens, you can quickly find the candid camera device to help you solve potential safety risks.Several detection methods: SET UP2: When a suspicious signal appears, the indicator pin oscillates in the green zone and alarms. SET UP3: The closer the signal gets to the suspect object, the more the pointer jumps to the yellow danger signal area.Automatic detection: it can identify, classify and record dangerous signals automatically. Prevent eavesdropping, candid photos and personal information leaks.Size: 138 * 60 * 28mmBattery capacity: 3500mAWorking current: 30mAFrequency: 1MHZ-6.5GHZContinuous work: 24-35 hoursCharging time: 1-2 hoursStandby time: 25 days
