Pinhole Cameras Nowadays, pinhole cameras are really hard to prevent, because there may be a camera hidden in an insignificant little thing in life. For example, when staying in a hotel or guesthouse, there may be pinhole cameras on both the remote control and the hot water kettle. There are also some inconspicuous cameras hidden on the TV or router. They pretend to be the structure of the electrical appliance itself, so as to photograph the normal life and personal privacy of some people. If some lawless elements sell these videos online, it will bring you a lot of unnecessary trouble.
Infrared scanning Therefore, before living in a strange environment, it is very necessary to check whether there is a hidden camera in the room. First of all, you can close the doors and windows after entering the room, close the curtains, then turn off all the light sources in the room to make the whole room in a dark state, and then turn on the camera of the mobile phone to scan the items in the room one by one. If you find a flashing point, you should turn on the light and focus on whether the camera is hidden in the flashing point.
Now many cameras can't find infrared scanning, and it's even harder to find it. Therefore, if you live in a strange environment, you should carefully check all the rooms before you live. In addition to cameras, mirrors are actually dangerous things, because mirrors installed in many places are double-sided. If there are double mirrors in the room, your privacy will be exposed. Therefore, whether you live in a strange place or do anything, you should pay attention to your privacy and prevent your information from being exposed.
