Is your hotel room, Airbnb or dressing room really private? Hidden Camera Detector helps you check any room in under 60 seconds. Scan the Wi-Fi network for IP cameras, catch hidden lens reflections with your flashlight, reveal invisible infrared night-vision cameras, and trace Bluetooth spy devices — all from your phone. 4 SCANNERS IN ONE APP 1. WI-FI & IP CAMERA SCAN - See every device sharing your Wi-Fi network. - Detect open video streams: RTSP (554), ONVIF (80/8080/8899/5000) and HTTP snapshots. - Match MAC addresses against known security-camera brands such as Hikvision, Dahua, Ezviz, Xiaomi, Tuya and Yoosee. 2. LENS GLINT FINDER - Uses your flash and a high-contrast optical filter to make hidden lenses visible. - Reveals the tiny reflective glint of a pinhole camera behind clocks, power outlets, smoke detectors, teddy bears and picture frames. 3.
