What could a camera detector pick up as a "potential camera"?

POSSIBLY a camera in your apt or a neighbor's apt or a security camara outside that's broadcasting wifi.  Unless you're doing crimes, you're probably not work spying on.  I know that I'm not. 

Sorry I'm so late 'coming to the party', but I've just received this article in my inbox.

It's entitled "5 Ways to Find Hidden Cameras in Any Room"

Hopefully, it will contain some information that you MAY find useful.

Firstly, there is no such thing as a functional, universal, "Camera detector".

A mobile phone can not receive anything other than WiFi or cellular frequencies, and those only with the correct data formats.

Unless someone is daft enough to use a WiFi connected camera - which could be picked up by anything with WiFi - a phone is useless as a bug or camera detector.

Adding apps/software cannot change the physical capabilities of the phone.

You can buy specialist "bug detectors", effectively a wide band spectrum analyzer, that can pick up radio signals from wireless bugs. One of those would also pick up a wireless video bug.

However, any "detector" can only pick up a radio signal, so a bug or camera that recorded internally (eg. to an SD card) would not be detected.

The chances of anyone bugging someone else house are next to zero.

Unless they had regular access to be able to swap batteries every day or two, a video bug would also need to be mains powered - it could only be fitted in to something that has a permanent power connection, so it did not need regular battery changes.

If you really want to check things, those are what to look at - by eye, no scam apps which will tell you nothing useful.

I don't think any app can detect a spy camera

True spy cameras use frequencies and formats no phone can pick up.

Buy a REAL spy cam detector like the K18 available on Amazon for under $30
