More than half of Americans said they were concerned about hidden cameras in the home.

According to a survey by the real estate investment company, 9% of vacation home renters found a hidden camera.

Spy cameras have been around for a long time. More than 30,000 cases of filming with hidden cameras were reported to the police in South Korea.

Kenneth Bombace, CEO of Global Threat Solutions, said that the number of hidden spy camera reports has increased due to the increasing accessibility and inexpensiveness of such cameras.

Hidden spy cameras can be found in hotels and rental properties.

The majority of covert cameras are hidden in household devices.

He said to look and see if it looks different than the norm.

Bombace said that spy cameras are usually connected to an electrical source.

He said the first thing he does in a bedroom is put the clock radios in a drawer.

The CEO of Advanced Operational Concepts said he does that as well.

The reflective glass from the camera's lens can be found even in well-hidden cameras.

If you shine the flashlight on something you think could be used to hide the camera, you will see a reflection in it, which is a good way of detecting if there is a camera.

It is necessary to locate hidden lens.

Many people will attempt to do amateur lens detection. You can miss a lot if you don't have a good search method.

Bombace said that a hidden camera needs to be connected to a local wi-fi network.

Hidden cameras must be connected to a local Wi-Fi network to be viewed remotely, said Global Threat Solutions CEO Kenneth Bombace.

The Fing app can identify cameras on the network.

Those who hide cameras can use a separate network to stream live video footage, but they can also use a scanning app to see how many networks are in the house.

Kody Kinzie, a security researcher at Varonis, warned that network scans may not catch everything.

He said to look for devices that broadcast their own network name.

Kinzie said to use an app like wiGLE to find devices that are broadcasting a network name.

spy camera detectors can detect hidden cameras. You can easily buy these online.

If the hidden camera is sending data, this method will work.

Many of them now haveSD cards that hold data to be retrieved after someone leaves. These are harder to detect.

Bombace said that the cheaper ones are probably not that good.

Bombace said that if it's $30, it's not that good. Better ones are going to cost a lot more.

Kinzie said that after locating a camera, immediately disconnected it without damaging it because the camera's firmware may contain identifying information.

Disconnect hidden cameras but don’t damage them, said Varonis security researcher Kody Kinzie.

Hidden cameras should be reported to the front desk, according to O'Rourke. He told them to move to another hotel.

He wouldn't trust any other room in the hotel if he found a camera in a room.

If litigation or criminal charges are to follow, Bombace recommends reporting hidden cameras to the police.

He said that you could give the report toAirbnb to prevent this person from doing it again.

Bombace said he wouldn't avoid renting a home because of spy cameras.

Common sense steps would be taken to protect yourself. He told them that they were not in their own home.
