Halo: detector cámara oculta

About this app

New hotel or Airbnb? Get your peace of mind back before letting your guard down.

Halo helps you scan a room for hidden cameras by combining three signals, all analyzed on your own mobile device. Nothing leaves your device: no servers, no account, and no location requests.

HOW IT HELPS
• Magnetic field: detects hidden electronics by their magnetic anomalies, comparing them to a calibrated baseline for the room (that's why it doesn't trigger with every plug).

• IR lenses: uses the camera to reveal infrared LEDs and lens reflections invisible to the naked eye.

• Local network: scans Wi-Fi for IP cameras with open ports (without requesting location permission).

• Guided sweep: a step-by-step checklist to ensure you don't miss any hotspots (smoke detectors, clocks, chargers, picture frames).

• PDF report: export and share the results as evidence.

WHY HALO IS DIFFERENT
• Fewer false positives: we measure deviations from a baseline, not absolute values.
• Real privacy: 100% on-device, no account required, no location permission needed.

• Honesty: We tell you what a mobile phone can and CANNOT detect.

• One-time payment, no subscription or surprise charges.

IMPORTANT: Halo is a support indicator, not a guarantee. No app replaces a careful physical inspection or a professional counter-surveillance officer. Cameras that are turned off, wired, or recording to an SD card may not be detectable from a phone.

Travel with peace of mind. Scan in one minute.
