Key Takeaways

  • Hidden camera technology is easily accessible, inexpensive, and can be placed inconspicuously in almost any object, posing a threat to privacy.
  • Hidden cameras are often placed in popular objects like wall clocks, power banks, picture frames, and decorations, making them difficult to detect.
  • There are different methods to find hidden cameras, including visual inspection, RF detectors, camera lens detectors, thermal imaging cameras, smartphones, and Wi-Fi scanners. Being cautious and familiarizing oneself with the law is important to protect privacy.

People rightly value their privacy, but advancing technology makes it easier than ever for someone to spy on you.

A subtle decoration in your hotel room or outlet at work may be a hidden camera. These sneaky disguises make it easy for someone to place an inconspicuous spying device anywhere. Worse of all, hidden camera tech is inexpensive and disturbingly simple to obtain through any online shop, no questions asked.

Luckily, there are plenty of ways to find hidden cameras before people have the chance to spy on you. Understanding where people place hidden cameras and how to detect them gives you peace of mind and more control over your privacy.

Are Hidden Cameras Illegal?

While it is perfectly legal to purchase hidden cameras, there are many state and federal regulations to consider. Hidden cameras fall in a legal gray zone depending on the location you record and the area you live.

Typically, hidden security cameras on your private property, like a home or garden, are not an issue. But if you then go on to rent out your property, whether for a long-term rental or Airbnb-type holiday let, failing to disclose the cameras becomes a problem, especially if they are hidden (rather than a proper surveillance camera installed without an attempt to hide its functionality and disclosed beforehand). Generally, if you are renting out a location, it is illegal to record guests without their consent.

By extension, this legality carries over to places like hostels, hotels, Airbnb rentals, and other places where you might stay yourself. In general, in scenarios where you have a reasonable expectation of privacy, recording with a hidden device (or any camera, for that matter) is illegal.

It gets complicated when the recorded subjects are employees rather than guests. Workplaces may sometimes have grounds to record you without permission, depending on the state you reside in. However, depending on your state, the company may have to inform its employees that they will be recorded.

Just because something is illegal does not mean everyone follows the rules, though. There are countless cases regarding guests who stumble upon hidden cameras in areas where they expect some level of privacy, which is why performing a hidden camera sweep may save you a lot of grief later.

Where Do People Put Hidden Cameras?

The whole point of a hidden camera is to remain hidden to catch subjects off guard. Hidden camera designers use several techniques to blend them into their surroundings expertly. While a hidden camera may be hidden in virtually anything, vendors mass-produce popular models and objects, which makes it a little easier to keep in mind during your hidden camera sweep.

  • Wall outlets
  • Screws/nails
  • Wall clocks/alarm clocks
  • USB drives
  • Power banks
  • Pens
  • Picture frames/paintings/artwork
  • Vents
  • Mirrors
  • Decorations (figurines, stuffed animals, vases, etc.)

Wall clocks and alarm clocks are particularly popular due to their size, which makes obscuring a camera and the hardware required to transmit data easier.

How to Detect Hidden Cameras

With so many potential hiding places for hidden cameras, starting your search may seem overwhelming. Luckily, there are a few different techniques used to find hidden cameras. Many of these don't involve any fancy equipment.

1. Visual Inspection

Observing your surroundings is the easiest way to spot cameras. When you know what to look for, hidden cameras may not stay hidden for long. There are some telltale visual clues to let you know that an object is a hidden camera.

Looking for out-of-place items or something that looks different on a regular object is a great start. Many people notice an awkward dot on an outlet or a sudden shiny bump on a vase are actually hidden cameras. If something seems out of place in your hotel or Airbnb suite, check it out!

It's also wise to make sure all the items in your room are what they claim to be. Check to make sure all outlets actually work and allow you to plug into them. Check to make sure mirrors are not two-way by conducting a reflection test. If you push your finger up against a "true mirror," the reflection of your fingertip should not touch your actual finger. If no gap exists, it may be a two-way mirror used for spying.

2. Radio Frequency (RF) Detectors

Purchasing an RF detector is an effective way to detect things you can't see with your naked eye. They work by sensing radio waves often emitted from spying devices. The idea is that most hidden cameras transmit their feed to another device.

Most commercial devices transmit radio waves at a frequency of 500MHz to 6GHz. Most standard RF detectors scan beyond this range. Be sure to shut down any devices you have that may set off the RF detector before you scare yourself into thinking you found a camera. Such items include things like cellular devices, laptops, and anything that uses Bluetooth.

3. Camera Lens Detectors

Although most hidden cameras transmit their feed, someone may have cameras that use local storage, like an SD card. These devices do not need radio signals and won't alert an RF detector of their presence. This lack of radio emission does not mean they'll remain invisible from any sensor.

As the name suggests, a camera lens detector senses camera lenses. They search surfaces for light reflection characteristic of a recording camera lens. If the sensor goes off, investigate the suspicious areas for any hidden cameras.

4. Thermal Imaging Cameras

Another invisible sign is a hidden camera gives off thermal energy. Electronics give off some heat when they're running—think about how your laptop or phone heats up after you use it for too long. Thermal cameras may uncover hidden "hot spots" that indicate an electronic device. While some items will naturally give off heat, you may want to investigate suspicious alerts like an overheating teddy bear or vase.

5. Smartphones

Smartphones are one of your best weapons against hidden cameras. Namely, they offer a much more affordable combination of a camera lens and an RF detector. There is a wide selection of apps that help uncover hidden cameras. They also have some valuable features that don't require any additional software or attachments.

Cameras require some illumination to record in complete darkness. The sensible solution most manufacturers use is infrared (IR) technology. The IR spectrum is not visible to the human eye. We need additional devices to uncover them. While it is entirely dark, use your front-facing camera (which does not have an IR filter) to look around your room. If you see any specks of light that you can't see without your camera, this may be a spying device.

6. Wi-Fi Scanner

Your smartphone isn't just equipped with a camera lens; you can use your smartphone to detect Wi-Fi networks and reveal the devices connected to them. You can also buy dedicated, handheld Wi-Fi and network scanners, though these are more niche.

However, given most folks have a smartphone, it's the easier and cheaper option.

Should You Worry About Hidden Cameras?

While you should not live in fear of everyone spying on you, it is reasonable to be cautious about potential hidden cameras. It only takes a minute or two to check a new room or building when you arrive, and it will help preserve your privacy and keep you protected; better safe than sorry! Familiarize yourself with the law so you know what your rights are.
