The K98 infrared feature helps you detect hidden cameras in your hotel room. When you fall asleep, you can turn on the vibration alarm function of K98 and hang it on the door of the hotel, which can effectively give you early warning.
You can place the K98 on anything you want to protect and turn on touch detection. At this time, as long as there is any slight vibration, the device will be issued an alarm, which can effectively protect your property security.
