How to detect hidden camera with mobile phone app

Last year, we had a customer in our law offices who thought that someone was spying on him.

As there are no professional countersurveillance services offered in our country (Kosovo), we decided to buy some equipment and I also made myself familiar with the issue.

,There are several different ways a spy camera can be detected:,First of all, you can use a so-called camera lens detector.

All these lens finders work with the same principle: a red (often flashing) LED light is directed at the suspected location and if theres indeed a camera lens there, you are able to see the reflection of the LED light on the lens through a filter.

,A camera lens finder.

This one is integrated into an RF-Detector.

These lens finders are inexpensive (USD 10 to 50), but on the downside, you need to shine the light directly at the camera lens to get a reflection.

This can be difficult sometimes, for example, if the camera is hidden under the ceiling.

Chances are good that youu2019ll miss a camera lens.

,Another way to detect a hidden camera is through its radiofrequency (RF) signal.

Most spy cameras on the market operate with a 2.

4 GHZ Wifi signal to transmit the images to a monitor.

This signal can be caught with a so-called RF-detector.

What you do is you switch off your own home wifi and look if thereu2019s still a strong signal around.

RF-detectors arenu2019t awfully expensive: I bought a very good one for USD 200.

The problem is that when the camera doesnt transmit, theres no signal that you can detect.

,One of my RF-Detectors.

You can find any electronic circuit, operating or not, with a so-called Nonlinear Junction Detector (NLJD).

This is a device that looks like a metal detector and can locate even a small SIM card.

The downside: this device will alert you, not only to a hidden camera but also to all other kinds of electronic devices.

In addition to this, NLJDs were originally used by the aircraft industry to find corrosion under the paint of aircraft and even a rusty nail can set them off.

They are also expensive; the cheapest ones go for USD 10,000.

,Last but not least, a thorough manual search, without any electronic detection devices, may be enough to find a hidden camera.

As with all other search methods, you should be systematic and thorough.

Free app to detect hidden cameras and microphones

I read some time ago about cameras in hotel rooms.

The suggestion was to download a program that would detect the existence of nearby transmitters.

The theory was that a camera or microphone would need access to the www and would therefore leave a heat signature (sort of).

,I got Fing.

I cannot remember if it was recommended in the article, but it must have been.

Otherwise I would not know of it.

,Fing is free (with ads).

,Fing simply tells you the surrounding devices it detects which are leaving signatures.

Here in my home, it is detecting 11 devices u2014 WiFi, tvu2019s, ipads, Nest cameras, etc.

,If that were suddenly 12, something would be up.

,In a hotel room, if you have strange devices detected, that might be a signal to look around closer.

,Its not a lot, but it is more than zero.

,Good luck, Sir.

I too trust my gut.

Listen to yours.
