Whether it's a hotel or vacation rental, you may wonder about hidden cameras. Follow this guide to learn how to find hidden cameras and help protect your privacy.
Imagine spending the money on a relaxing holiday only to discover you've been watched the entire time.
While this may sound like the plot of a new horror movie, it has unfortunately become a reality for many travellers.
For perspective, more than one in 10 guests have discovered a hidden camera in their vacation rentals.
And it doesn't stop there, as people have discovered hidden cameras in public restrooms, hotel rooms, dressing rooms, and more.
Even though hidden cameras are sometimes used outside the house for home security, some perpetrators may use them for nefarious purposes, such as snooping on your personal life and invading your privacy.
Because of this, knowing how to detect hidden cameras has never been more important to protect your personal privacy. To help you in your search, we’ve pared down 10 different hidden camera detection methods:
Follow this guide to learn more about how to find hidden cameras, their common hiding spots, what they look like, and what to do if you find one.
Let’s get started.
1. Look for suspicious objects
If you think you may be in an area that has hidden cameras, a good starting point is completing a thorough physical search of your surroundings. While scanning the room, keep an eye out for any objects that look out of the ordinary. If it’s an area you've been in before, check and see if anything looks as if it has been moved or rearranged.
During your search, be sure to pay close attention to objects that are commonly used as hidden cameras or as ways to disguise them, including clocks, smoke detectors, wall decor, and USB charging blocks.
If you find anything that appears suspicious, be sure to cover the camera and unplug it if you can. In some cases, hidden cameras may have built-in batteries that allow them to run even after they’re unplugged.
2. Check for lights
Another helpful way to quickly locate a hidden camera is to check for lights. To do this, be sure to get the room as dark as possible. You can do this by waiting until nighttime, closing all your blinds, and shutting off or unplugging any trusted light sources.
Then, look around the room for any objects that emit light. While this isn’t true for all devices, some hidden cameras may have a small LED light that will blink or shine in the darkness.
3. Use a torch
In some cases, you may be able to check for hidden cameras by using a torch. Like the last detection method, you’ll want to get the room as dark as possible. Then, shine the torch around the room and check carefully for any tiny reflections.
These reflections may be blue or purple and could be coming from a small camera lens. Once you see a reflection, make sure you give the object a close inspection to determine if it’s a hidden camera.
4. Check any mirrors
Some clever creeps even go as far as hiding cameras behind a two-way mirror. Fortunately, there is a simple way you can check and see if the mirrors in your area are safe or if they’re two-way mirrors in disguise.
To test your mirror, start by placing the tip of your finger on the surface of the mirror. After doing so, look at the gap between your fingertip and its reflection. If there is a visible gap between the two, it’s a real mirror. If it appears as if your fingertip and its reflection are touching tip to tip, it may be a two-way mirror and could have a camera behind it.
You can also detect a two-way mirror by knocking on it. Knocking on a two-way mirror will result in a hollow sound compared to a real mirror.
5. Use your smartphone camera
Many types of hidden cameras emit infrared light while in use. While you won’t be able to see this yourself, your smartphone might be able to help. To test if your smartphone camera can detect infrared light, you can use an infrared remote control such as a TV remote.
First, try pointing your phone camera at the end of the remote. If your smartphone screen shows a burst of purple or white light, that’s a sign that your camera is picking up the infrared light. In most cases, it will be your device’s front-facing camera that works, as many rear-facing cameras have infrared filters.
If your smartphone passes the remote test, you’ll want to get your room as dark as you can. Then, use your phone camera to scan the room to detect and examine any sources of infrared light.
6. Scan your Wi-Fi network
Some hidden cameras may connect to the internet so they can be monitored remotely. If a hidden camera uses Wi-Fi and is connected to the same network as you, you may have a chance of detecting the camera via a scan of your wireless network.
To scan your Wi-Fi network to detect hidden cameras, you’ll first need to download a network scanning application. To do so, open your smartphone's native app store and search “network scanner.” Once you find an application you like, install it and follow the instructions.
For a network scanner to work, you’ll need to be connected to the Wi-Fi router you’re looking to scan. While looking at the app’s results, keep an eye out for any device names that you don’t recognise or seem suspicious, like “IPcamera,” for example.
7. Check for signal interference
In addition to infrared light, many surveillance cameras also emit radio waves that can disrupt nearby phone calls. For example, you may experience annoying buzzing or crackling during a phone call if you’re close to a hidden camera.
To use this detection method, call a family member or friend and ask them to stay on the line. During your call, slowly walk around the area and listen closely for any interference. If you notice a decrease in call quality in certain areas, you may be close to a hidden camera. If so, check the area thoroughly for anything suspicious.
Keep in mind that this method isn’t a guarantee, as not all cameras will interfere with a phone call. On the flip side, your phone could be interfering with other signals or have bad reception unrelated to a hidden camera.
8. Use a hidden camera detector app
Another way you can use your smartphone to help find hidden cameras is to download a hidden camera detector app. When searching for a hidden camera detector app, be sure to stick to your device’s native app store, as third-party app stores may contain malware.
This method is a solid option for detecting hidden cameras because many of the apps combine multiple techniques, including Wi-Fi scanning, Bluetooth scanning, and infrared detection. Once you’ve downloaded the app, be sure to carefully follow the instructions to ensure you’re taking the best steps to find a hidden camera.
9. Use a hidden camera detector
As an alternative method to smartphone apps, you can purchase a specialised device to find hidden cameras. These spy camera detectors work by scanning for radio frequency (RF) signals, which are electromagnetic waves used by hidden cameras and other electronics to transmit information through the air. These devices can be found online at websites such as Amazon, with prices ranging from $20 to hundreds of pounds.
If you go this route, be sure to carefully follow the instructions that come with your device. Common household items such as kitchen appliances, Wi-Fi routers, and TVs may interfere with your detection device, so unplugging them is the safest bet. When in doubt, refer to the manual that came with your device to best perform your hidden camera search.
While this is a more expensive method in comparison to the others, these devices are specifically designed for locating hidden cameras. If the other detection methods are unsuccessful and you’re still suspicious that there is a camera in your area, purchasing a hidden camera detector may be worth the investment.
Please note that certain hidden cameras can use multiple frequencies that alternate rapidly and may be undetectable to some hidden camera detectors. Fortunately, surveillance cameras with such capabilities are much more expensive and are less likely to be used.
10. Hire a professional
Whether the other detection methods come up short or you’d rather sit back and let the pros do the work for you, hiring an expert can be a reliable way to ensure the area is free of any privacy threats.
By hiring a specialist, you can benefit from their expertise and specialized equipment without having to purchase any equipment yourself. When looking for a qualified professional in your area, be sure to do your research and read any available reviews before making your decision.
Most common places to spot hidden cameras
No matter which detection method you use, there are common objects and places that frequently house hidden cameras. Some hidden cameras can even be as small as a screw, making them difficult to find with a quick glance. Because of this, it’s important that you pay extra close attention to these common objects and hiding spots, including: ·
