Here is a professional and engaging English translation of your app's promotional copy. I have optimized the wording to sound natural, clear, and appealing to global users.

This is a professional video surveillance app featuring three powerful modes: Parcel Evidence, Dashcam, and Motion Capture.

Parcel Evidence Mode: The app automatically starts recording the moment it detects data sent from a barcode scanner. There is no recording time limit. When it detects the next scan, it saves the current video and immediately starts a new recording.

Dashcam Mode: The app automatically records in a continuous loop via a floating window, ensuring it won't interfere with your navigation apps.

Motion Capture Mode: The app automatically takes photos or records videos whenever it detects people or vehicles entering the frame. It is perfect for various settings, including bedrooms, construction sites, and entrances.

Privacy & Security First: To protect your privacy, all captured photos and videos are stored strictly on your local device. No background cloud uploads, no privacy leaks.
