How do people prevent this? I have yet to find a device or tool that would discover such hidden cameras.

A lot of spy cameras have an IR light that will be visible if viewed through your phone camera, so turning out the lights and doing a quick phone camera sweep can help.

I'm guessing this won't apply to all cameras though.

Phone cameras typically have IR filters that filter out that light. You need to modify the camera (or have an exceptionally cheap one?) to not have it filtered.

		It used to be that the front/selfie camera would not have a filter.

it needs to draw power, so the ultimate way is to look for anything generating radio waves. there a few inductive methods to "listen" to electrical pulses near by, but you have to sweep every part of the room, take apart every source of EM. e.g.: light fixtures drawing power while turned off. same with wall sockets.

Explode a paint bomb in the center of the room that applies an even coat to everything. It’s the only way to be sure.

		It’s a joke inspired by Mr Bean: https://youtu.be/EiZoSuNej5U?si=wpOzf7C-X2NvhRDd. It would take care of any cameras but I doubt the owners would be too pleased!

I saw an documentation about this some time ago, unfortunatley there is no reliable consumer method hat detects a well hidden non IR based camera.

The popular in Korea anti-spy cameras/reflecting optical devices that find even pinhole camera lens. Something like this: https://www.amazon.com/dp/B0CQM298P6 But buy from somewhere other than Amazon. ;)
