Hidden camera and tracker stories can look like isolated incidents — until you line the numbers up. Together they reveal a growing, global epidemic. Here are the most striking figures from recent studies and investigations, and what they mean for your privacy.
The state of vacation rentals
- 47% — travelers who say they have discovered a camera in a rental property, per IPX1031's 2025 survey. In 2023 it was 25%; the figure nearly doubled in two years.
- 1 in 12 — vacation rentals estimated to contain a hidden camera, according to an independent 2024 study.
- 35,000+ — surveillance-device complaints Airbnb received over a decade, uncovered by CNN's 2024 investigation.
- 55% — hosts in the same 2025 survey who admit to still using indoor cameras despite the platform ban.
The tracker front
- 317% — the single-year rise in AirTag stalking cases (Cybernews).
- 100+ — tracking-device charges filed in Florida in 2025 alone; the state now treats planting a tracker as a felony punishable by up to 15 years.
- 9 months — how long a flight attendant recorded in airplane lavatories in one US case; the sentence: 18.5 years.
The global scale
A February 2026 BBC investigation found more than 180 cameras hidden in hotel rooms in China alone, livestreaming guests to Telegram subscribers — a single channel had 10,000 members. South Korea's 'molka' epidemic continues with thousands of cases a year despite stricter laws, and Türkiye's Sapanca bungalow and Pamukkale rental-flat cases showed the local dimension of the problem.
What these numbers mean for you
Two clear takeaways. First: hidden surveillance is no longer a marginal, someone-else's-problem risk — if you use short-term rentals, your odds of encountering it are statistically significant. Second: as devices get cheaper and smaller, visual checks alone fall short; 64% of travelers admit they wouldn't know how to detect a hidden camera.
The answer is layered scanning: lens-reflection checks, network and Bluetooth scans, EMF measurement and ultrasonic analysis together leave almost nowhere to hide. SenseRadar combines all of these layers on your phone — a two-minute sweep can keep these statistics from becoming your story.
