Accuracy depends on the method and environment. Detector apps are most useful for organizing clues, not issuing a final verdict.
Important: No consumer app or inspection method can guarantee that a space is camera-free. Use multiple checks and contact a qualified professional for high-risk situations.
Network accuracy
Strong for identifying visible devices on a trusted local network, weak against isolation, offline storage, and cellular cameras.
Magnetic sensor accuracy
Useful near powered electronics but highly prone to metal and electrical false positives.
Lens and infrared accuracy
Useful when a lens or infrared LED is visible from the correct angle, but both methods miss concealed or inactive devices.
Improve your result
- Use more than one method.
- Verify every result against a physical object.
- Repeat scans from different locations.
- Escalate high-risk cases to a professional.
