You may have a hidden camera at home or in your office.

You may have a hidden camera at home or in your office.

Hidden cameras and bugs are needed to see if there’s something valuable in your suitcase and where you can hide your money and documents. In addition, the resolution of modern cameras will allow you to view the password from your smartphone or safe.

Theoretically, with cameras, owners can see if you broke their bed or broke a mirror. But you can’t show videos from hidden cameras in court. On the contrary, it’s the owner’s own fault.

Like a violation of privacy.

It can be a miniature lens and a pair of wires that go into the wall. There are crumbs that can be disguised as a screw or the eye of a small souvenir doll.

Cameras and eavesdropping devices are sold alone or integrated into other appliances or interior items. It can be anything from an outlet to a child’s toy, from a TV to a furniture pen.

Funny electronic device. Sports bottle for water. It’s like a forgotten fitness tracker. An extra remote from the TV that doesn’t work. An old camera that’s here for the entourage. Kettle, coffee maker, alarm clock, USB-switch, smart light bulb are just the most popular examples.

Recording can be done around the clock, starting as soon as the sensor detects movement or sound.

Other option: recording starts if you call the gadget. Such devices must have a GSM module and a slot for a SIM card.


  • Upper corners of the room. That’s where the best view for the camera comes from.
  • Sockets. If you can’t figure out which device this or that wire is leading to, unplug it. Although, of course, spy devices are more likely to run on batteries or hidden wiring.
  • Kids toys and souvenirs. Especially with eyes and set above your growth level.
  • Picture frames, wall clock. Spy gadgets can be attached to their back surface.
  • Technician who somehow doesn’t work – from sconces and desk lamps to handsets.
  • Ventilation grids and hoods. Behind the grid can hide the camera’s peephole.
  • Any strange devices and sensors. Take a picture of them and look for photos on the Internet. Maybe you shouldn’t be worried.

Say directly: the chances that your apartment, hotel room or apartment is under surveillance are objectively low. But you really do buckle up in the car, although the risk of accident is also low? It’s better to get out of here.

How to look for wiretaps and cameras in the room


1. Break up the room into sectors. If you are not alone / not alone, divide the sectors between them, and then double-check each other.

2. Search from top to bottom. Cameras are more often placed at the top of the room: this way they are less visible, but the view is better.

3. Check each item, even if it is a normal switch or shelf with books. Cameras are placed exactly where you are unlikely to look.

4. Where do people usually take their clothes off or take apart their suitcases? Take a look at places where you can get a good view of these areas.

5. Examine the doors. The door frame will definitely fit a small camera.

6. Are there any double objects in the room: clocks, kettles, staff communication devices? Perhaps one gadget is real, and the other is a disguised spy.

7. Are there any homogeneous objects that are different from the others? For example, all sockets may be gray and one may be white. Maybe they just didn’t bother when repairing. Maybe on AliExpress it was impossible to choose the color of the socket with built-in camera…

8. On balconies, in armchairs and sofas, under tables and cabinets are often placed microphones. Feel free to take a look around, especially if you are here on business and have important negotiations ahead.
9. Look at the ceiling. Cameras can be next to chandeliers and built-in spotlights. If the ceiling is made of tiles, check to see if they are the same colour, if one of the tiles has any recent installation marks.

10. Check the mirror in your bathroom. Sometimes instead of the usual mirrors you put the so-called Gesells mirrors, transparent on one side. They can be used to peek at you from the next room.

How to understand that you’re being watched through mirrors


Touch the mirror with your finger: it should be about 5 mm from the mirror to the reflection. This is the average thickness of glass.

If the distance is shorter, try to see what’s behind the mirror and shine a smartphone flashlight into it. You may see a room or a hidden camera behind the mirror.

Hang a towel on the mirror and sleep quietly.

Sometimes at gas stations and in bars you use thin metal films instead of mirrors. This is done so that shards of broken mirrors do not hurt customers.

The film looks almost like a mirror Gezella: your finger will touch your reflection. But the film is thinner and usually installed without a frame.

How to Check Room with Smartphone


Step one: turn off the light. See if the LEDs are flashing somewhere. They can be of any color. Mostly white, red, blue. In daylight, the LEDs are not so visible.

Step two: turn on the flashlight. If you notice a glare somewhere, it’s quite possible that it’s the glass of the camera lens.

Even if you are not sure if it is a camera, take a closer look, try to take a picture of the place and enlarge it. If you are paranoid, glue a suspicious “window” near the LED with a plaster or a damp piece of paper and sleep quietly. Technique (both spy and ordinary) you will not spoil it, you will not have to compensate for damages.

If you have a thermal camera for your smartphone, you can use it too.
Look through the heat chamber walls, wardrobes, bed headboard, doors, bath walls. You may find some suspicious warm spots.

How to find cameras with remote control from TV


If your room has a TV or air conditioning, you will need a remote control. Hidden night vision cameras use infrared backlighting. The human eye can’t see it: it detects waves in the range of 390-700 nm, while infrared waves are longer: 740-2 million nm.

A smartphone’s main camera may be insensitive to infrared light, especially on older models. But the sensors on the front panel probably have such a possibility – for example, to unlock the smartphone in the face.

Xiaomi Mi 8 and Pocophone F1, as well as other smartphones in recent years, even have an infrared projector built in – it lights up your face so that the front camera can recognize it better, although you can’t see it.

So, to find the cameras, take the remote and run the Camera application. Point the remote in different directions, press any buttons and look at the smartphone screen. The light reflected by the camera will be visible in the photo.

Whiche apps can help you find spyware


Hidden Camera Detector search will find the original application and its analogues, also free or paid. Hidden Camera Detector directly analyzes magnetic activity and light pattern in the room.

If the application finds suspicious magnetic wave sources, it reports it. The invisible to the eye light it marks in the picture on the screen with a white circle.

If your smartphone doesn’t have a magnetic sensor, you can only look for hidden cameras.
The developers have warned about possible false triggers of the application near refrigerators, microwave ovens and other electronics. Disconnect them so that the results are more accurate.

By the way, in Google Pixel 4 found a pre-installed application HedgeCam 2, which activates the IR camera on your smartphone. It lets you see hidden cameras. It’s a shame it doesn’t exist for an iPhone.

How else do spy devices give themselves away


Often cameras and listening devices transmit data over Wi-Fi or Bluetooth. It’s easier this way: there’s no need to build in a tiny “spy” memory module, which will save a few hours of FullHD-video.

Turn on Wi-Fi and Bluetooth on your smartphone and see which devices are around you. If the room is large enough, you can even walk around changing the signal strength (the number of “sticks”) to see where the gadget is.

If the name of the camera on the network left by default, its name may be something like 720r, 1080r (indicate resolution) or IP, cam, etc. If you have found such a device, you can directly ask the administration or apartment owners why it is needed and what it does. Usually by the reaction you can understand what is happening.

In the news section “oh, what a funny thing” my colleague who thought: strange that in his bedroom, rented through AirBnB, there is the only motion detector – and voila, it’s an IP camera connected to the network.

It’s quite possible that it’s a camera in the hallway that’s really needed for security. Everything else is a reason to write in support of AirBnB, Booking or other services through which you have rented your accommodation.

If you have a router in your room, you can try unplugging it and see if the connected devices are missing from the list. Use the Internet while you are awake and you can do without it at night.

If you have a computer or other device on Linux, you can run script by developer Julian Oliver.
The script scans the Wi-Fi network, finds devices similar to DropCam and Withings cameras, and disables them.

For cameras from these manufacturers, Mac addresses start at 30:8C:FB and 00:24:E4 respectively. You can add other masks to the script (32 line), and then the corresponding devices will be disconnected from the system.

Sometimes such cameras can act as baby monitors. But more often they are used just in advanced video surveillance systems.


The first means is a radio signal detector or field indicator. A device similar to a radio emits a squeak as it approaches the source of the signal. For example, a camera or listening device that transmits data via radio waves: Wi-Fi, Bluetooth, traditional FM or AM.

Security professionals examine rooms with these detectors before negotiations or important meetings. They “paint” walls and furniture: pass the detector first from top to bottom, then “paint” a strip from bottom to top. If there is a bug nearby, the device will beep, and the closer to the detector, the stronger.

Typically, the wiretap will operate in the 10 MHz to 8 GHz range. The detectors cover a wider range (10 Hz up to 24 GHz or more) for sure.

The detector costs an average of $100. You can find it cheaper on Aliexpress:

The second tool is the camera lens detector. It can detect a glare from the lens: it illuminates it and highlights it more strongly on the screen.

There are universal options. They track both the radio signal and the highlights of potential cameras. They cost more, from $150-200.

Cheap field detectors like the popular BugHunter have a serious disadvantage: they scan the situation in real time. If a spy gadget accumulates data and transmits every few minutes, you may not even notice the moment of transmission.

More expensive models can operate in tracking mode. They scan the space continuously and will detect the bug as soon as it starts transmitting information.

Tip: Before using the detectors, turn off your smartphone, laptop, router and other devices that may be emitting a radio signal. This will speed up the search and eliminate false alarms.

Sometimes thermal imaging cameras are also used. They are more accurate than thermal cameras for smartphones and allow you to see even small spy devices, hidden behind furniture or in equipment.

How to protect against spy devices


First of all, close / turn everything that seems suspicious to you to the wall. And also turn off the router in your room for the night, unplug the equipment you do not need right now.

One of the easiest ways to fight a wiretap is to turn on music or white noise loudly, put the headset on and talk through it. Your microphone will be able to perceive your speech and cut off any extraneous noise, while the wiretap microphone will record something unintelligible.

Professionals use generators of acoustic, ultrasonic and electromagnetic interference that disable voice recorders. In theory, mobile phones and expensive voice recorders like “Dwarf” are shielded from such interference. But suppressors “Buben-Ultra” and other profile options are effective even in this case.

Finally, create whole “quiet rooms” in which suppress the transmission of any signals and sounds. In large companies and intelligence agencies have their own “quiet room. This is a rule of good tone, as is regular scanning of offices for wiretapping.

“Call the police if you find something suspicious

In st. 137 of the Criminal Code of the Russian Federation clearly spells out liability for illegal collection of information that constitutes personal or family secret. The punishment for this for an individual is a fine of up to 200 thousand rubles, up to 2 years in prison, etc. If a person used his official position to wiretap or record video, the fine will be from 100 to 300 thousand rubles, up to 4 years in prison, etc. The penalty for this is a fine of up to 2 years in prison.

If you find cameras or wiretaps in your room, do not touch them. There are several options for solving the problem.

First of all, you can talk to the hotel administration or the owners of apartments and possibly get a room of the highest category and other “buns” if you’re ready to turn a blind eye to espionage. Just take a picture of everything you found on the video.

If you rented through, AirBnB and similar services, write to their support. You will most likely receive a refund for your services, and an unscrupulous landlord will be punished by at least removing it from the platform.

Your rights are violated and it is perfectly normal to defend them. True, it can take a while, you won’t get much sleep and so on. Be prepared for that.
