Can a power outage effectively prevent hotel cameras?

It will stop some of them. Nowadays, many cameras have their own batteries, which can shoot without electricity, and some can last for more than 30 hours. You should pay attention to safety outside.

Then, after turning off the power for more than 24 hours and surviving the working time supported by the battery, most pinhole cameras with their own power supply have a certain probability of being turned off. It's like killing 800 enemies and losing 1000, but it may not be completely destroyed in the end.

Turn off the lights, turn on the phone camera in the dark, and then we take pictures of the patch panel in the room. If there is infrared light, it means there is a camera inside.

There are some hardware devices on the market that can detect some pinhole cameras, but the cost performance is low. There is a sneak shot detection in the toolbox of 360 Mobile Guard.

The focus is on the position facing the bed and bathroom. Especially for 100 common pinhole camera camouflage products, such as remote controllers, sockets, smoke alarms, etc. We should examine them more carefully.

Be sure to check every corner of the room carefully, especially where there are gaps. When a suspicious hole is found, turn on the mobile phone flashlight to illuminate the hole. If there is reflection, it means there can be a pinhole camera. The room power-off method is used for some pinhole cameras that need continuous power supply without electricity. In order to avoid being photographed, you can turn off the power of the room before going to bed.
