The rise of hidden cameras in rental properties has become a concerning issue for travelers, with reports of secret surveillance devices making headlines worldwide. While most hosts use security cameras responsibly, the rare instances of malicious misuse have made it vital for guests to know how to protect their privacy. Whether you’re staying in an Airbnb, hotel, or house rental, taking a few proactive steps to detect hidden cameras can ensure your peace of mind. This guide will walk you through practical, easy-to-follow techniques to safeguard your personal space and privacy during your stay.
1. Start by Scanning Plugged-In Devices

Hidden cameras often rely on constant power, so your first step should be inspecting all devices plugged into outlets. Alarm clocks, smoke detectors, USB chargers, and even carbon monoxide detectors can house tiny, hidden lenses. Pay close attention to any item that seems out of place or recently added.
2. Use Your Phone’s Flashlight

A simple yet effective technique is to shine your phone’s flashlight on any suspicious items. Hidden lenses may glint or reflect light, revealing their location. Focus on small openings or holes in appliances, decor, or electronics where a camera could be concealed.
3. Check for Unusual Wi-Fi Connections

Many hidden cameras require Wi-Fi to stream footage. Use a free network scanning app to identify unusual or unknown devices connected to the property’s network. Strange device names or long strings of random characters are red flags. If you suspect a device, unplug it and check if it disappears from the list.
4. Inspect Mirrors and Picture Frames

Mirrors and picture frames are classic hiding spots for cameras. Run your fingers along their edges and check for any irregularities or small holes. In the case of two-way mirrors, you can perform the “fingernail test”: press your nail against the glass. If there’s a gap between your nail and its reflection, it’s a standard mirror. If there’s no gap, it could be a two-way mirror.
5. Examine Light Fixtures and Ceiling Areas

Cameras are often placed in high, inconspicuous spots, like light fixtures or smoke alarms. Look up and check for small holes or irregularities. You might also notice blinking lights or other unusual signs of a hidden device.
6. Look for QR Codes on Devices

Some hidden cameras come with QR codes that connect to their apps. If you find a QR code on a device that doesn’t normally have one, scan it with your phone. If it leads to a suspicious app or prompts a Wi-Fi connection, you’ve likely found a hidden camera.
7. Perform a Thermal Heat Scan

Hidden cameras emit heat, especially when actively recording. If you have access to a thermal detector, use it to identify devices that seem unusually warm. Focus on plugged-in electronics or objects that have no obvious reason to produce heat.
8. Use a Lens Detector or RF Detector

If you have access to specialized equipment, use a lens detector to locate hidden lenses by scanning for reflected light. Radio frequency (RF) detectors can also identify cameras actively transmitting signals. Keep in mind that these tools may pick up other electronics as well, so you’ll need to interpret the results carefully.
9. Scrutinize Household Items for Irregularities

Pay close attention to small household items, such as books, buttons, or even stuffed animals. Anything that looks slightly off – like a button that doesn’t match others or a teddy bear with a strange hole – deserves a closer look.
Hidden Cameras: A Growing Concern

The rise in hidden camera incidents has made travelers increasingly cautious. While the majority of hosts use cameras to protect their property or monitor outdoor areas, a small minority misuse these devices for malicious purposes. This growing issue highlights the importance of being vigilant when staying in rentals.
Privacy Laws and Platform Policies

Many rental platforms now ban indoor surveillance devices, especially in sensitive areas like bedrooms and bathrooms. However, cameras might still exist in less conspicuous spaces. Knowing the laws and rental policies can empower you to take action if you find a camera in your Airbnb.
Why Hidden Cameras Are Often Poorly Concealed

Most hidden cameras are not the sophisticated devices you see in spy movies. Instead, they’re often commercially available items purchased online. This makes them relatively easy to spot with basic observation skills and a little persistence.
What to Do If You Find a Camera

If you discover a hidden camera, do not remove or damage it. Instead, unplug or cover the device and report it immediately to the rental platform or local authorities. In sensitive cases, such as cameras found in bathrooms, consider relocating to another property to ensure your safety and comfort.
While the idea of being watched is unsettling, it’s important to remember that most rentals are safe and managed by responsible hosts. By taking a few minutes to check for hidden cameras, you can enjoy your stay with peace of mind, knowing your privacy is protected.
