Review on 🔁 OREI HDMI Multi-Viewer 4x1 Seamless HDMI Switch - 4 Ports, IR Remote, Up to 1080p Support, Security Camera, 4 in 1 HDMI Switch by Ayush Bonuccelli

I bought this box (HD-201P) because I wanted to see my front door security camera (via HDMI player) while still watching TV. This block works absolutely perfectly for that. I'm glad I did NOT get a 4-sided multi-view version for this purpose, although it had more inputs and isn't more expensive - it's just not the same as PiP. Pros: - PiP has several handy layout options including screen angle and 3 different size options. Also supports side-by-side modes and weird stretch modes, but you won't be using them. IR and RS232 support simplifies automation. No framerate drop.
