📺 DualZ Stream Player

📱 What is DualZ Stream Player?

DualZ Stream Player is a specialized video streaming application designed to view HLS video streams with support for multi-camera mosaic grids. The app allows you to view a 2×2 camera grid and switch between individual camera views or view all cameras simultaneously.

2. Deep Links

Click or tap on a dualz:// link from:

• Email, Messages, WhatsApp
• Safari or any browser
• Any app that supports custom URL schemes

Example: dualz://MzQuMjQxLjYuMTM3OjQ=

3. Universal Links

Click on an https://dualz.com/s/ or https://dualz.com/stream/ link:

• More professional appearance
• Works from web browsers
• Shows fallback page if app not installed
