A Wi-Fi scan can reveal devices visible on the same local network. It is useful evidence, but it cannot see every camera.
Join only an authorized network
Scan networks you own or have permission to use. Avoid entering credentials into unfamiliar tools.
Create a list of known devices
- Identify your phone, router, TV, speaker, lock, and streaming boxes.
- Note device names, IP addresses, and manufacturers.
- Switch known devices off one at a time when practical.
Investigate unknown results
Search the manufacturer or MAC vendor and match the result to a physical object. Unknown means unidentified, not dangerous.
Know what a scan misses
Guest isolation, separate networks, local storage, powered-off devices, and cellular connections can all hide cameras from a network scan.
Frequently asked questions
Can hotel Wi-Fi show every camera?
No. Hotels commonly isolate guest devices, and surveillance systems may use separate networks.
What device names suggest a camera?
Names or manufacturers associated with IP cameras deserve review, but names can be changed or absent.
Should I disconnect an unknown device?
Do not interfere with equipment you do not own. Document credible concerns and contact the property or authorities.
