Wi-Fi Hidden Camera Checker
Give the checker the list of devices on your rental's Wi-Fi. It shows which devices a camera maker made, so you know where to look first.
Get the device list
- Join the rental's Wi-Fi network.
- Open the free Fing app and scan the network.
- In Fing, tap Share, then CSV. Save the file, then tap Open a file below.
- No file? Type the maker names that Fing shows, one on each line, and tap Check devices.
Only have a screenshot of Fing? On an iPhone, press and hold the text in the photo to copy it (Live Text). On Android, use Google Lens. Then paste the text below.
Have the router password? The router's connected-devices page can show devices that Fing cannot see, for example on a separate guest network. Copy the list and paste it below.
Your list stays on this device. The check runs in your browser and sends no device data to any server.
Honest limits
- A camera that is not on the network you scanned does not show up. Some cameras only record to an SD card, or use a mobile network.
- A camera on a different or hidden network does not show up. Many rentals have a separate network for the host's devices.
- "Maker not on our camera list" is not proof that a device is not a camera.
- A private (random) address is unknown, not safe.
- A device with no name and no hardware address is unknown, not safe.
Use this check with a physical search. The 5-minute room sweep checklist walks you through one.
How the check works
Every network device has a hardware address (a MAC address). The first part of the address shows the company that registered it. The checker compares each address with the public registries of the IEEE Registration Authority, and keeps only the companies that make cameras or the chips that cheap cameras use. The list was downloaded on October 18, 2026.
The checker also reads device and maker names, such as "Wyze" or "IPCAM". When the address and the name give different results, the stronger result wins.
Phones, tablets and laptops often use a private address that changes. That address shows no maker, so the checker marks it as unknown. A device that the list shows with no name, maker or hardware address is unknown too.
