FAQs
Q: Does this hidden spy camera detector work for wired cameras that do not emit wireless RF signals?
A: Yes. The AK400 has infrared lens detection function. Even for wired cameras without radio frequency signals, you can turn on the infrared lens finder to spot camera lenses by their reflective glow. It combines RF scanning and lens optical detection for wider coverage.
Q: Will other common electronic devices, such as mobile phones or Wi-Fi routers, trigger false alarms?
A: Ordinary electronic devices may emit radio frequency signals and trigger alarms. When you hear the alarm sound, you should bring the detector closer to locate the exact source of the signal, or move WIFI and mobile phones away from the detection target location before conducting the detection.
Q: Does the sound alarm volume adjust to different signal strength?
A: It uses an audio alert system. As you move the infrared hidden camera detector closer to a transmitting device, the alarm will become more frequent to help you pinpoint the exact location of the hidden gadget.
Q: Does the portable camera detector work in dark rooms or low-light environments?
A: Yes. The infrared lens detection function performs well in dim or dark spaces, which helps spot reflective camera lenses when room lighting is poor.
