Turn the power off.
Because the pinhole camera power consumption is very large, candid camera may use the room power. We can turn off the main power of the room so that the pinhole camera doesn't work properly.
Reduce the illumination.
Turn off the lights in the room, reduce the illumination, ordinary wireless pinhole camera cannot record a clear picture, which is one of the easiest ways.
Avoid unidentified people entering the room.
When bathing, you should pay attention to whether the doors and windows are closed. In public places, such as hotels, public locker rooms or public toilet, you should pay attention to whether there are any suspicious people or inappropriate goods around them.
Using professional probes.
You can buy a better detection device, so that you can detect any pinholes or eavesdropping devices, and take precautions against them.
