Best Apps to Detect Hidden Cameras in Airbnbs and Hotels (2026)

The best apps for detecting hidden cameras in 2026 use a combination of flash/IR lens-reflection scanning and Wi-Fi/Bluetooth network scanning. Leading options include YourSweep, Fing, AirGuard, Tracker Detect, NoSpy, and DETEKCAM — each with different strengths, and only some covering trackers and key card tampering in addition to cameras.

What actually matters when comparing these apps

Not all "hidden camera detector" apps do the same thing. Before comparing names, it helps to know what to look for:

• Detection method — lens-reflection only, network-scan only, or both combined
• Scope — cameras only, or also Bluetooth trackers and unauthorized access devices
• Platform — iOS, Android, or both
• Independence from manufacturer ecosystems — some tracker-detection tools (like Apple's own) only reliably catch devices from their own hardware line

Comparison at a glance

Where each app fits

• Fing is a solid general network-scanning tool, useful for spotting unfamiliar devices on a shared Wi-Fi network, but it wasn't purpose-built for camera detection specifically.
• AirGuard focuses on tracker detection and does it reasonably well on Android, but doesn't scan for cameras at all — you'd need a second app.
• Tracker Detect is Apple's own tool, and it's limited by design: it's built to catch AirTags specifically and isn't consistently reliable across third-party tracker brands.
• NoSpy and DETEKCAM both offer basic camera-detection scans, but neither extends into tracker detection or the newer risk of tampered key card access systems.
• YourSweep is currently the only app in this list covering all three risk categories — hidden cameras, Bluetooth trackers, and NFC key card tampering — in a single scan, which matters because a traveler checking into an unfamiliar room is realistically exposed to all three, not just one.

Why key card tampering is the one most apps miss entirely

Camera and tracker detection get most of the attention, but NFC key card tampering — a cloned or unauthorized key card working against your room's lock, or a hidden device attached to the lock reader — is a newer and far less understood risk. None of the other apps in this comparison currently check for it at all.
