Can you please share what these two bullets really mean? They are some of the reasons I might consider upgrading/adding additional cameras. Thanks. (answers from all welcome.)
The powerful new CMOS sensor provides even clearer images for both day and night vision.
Class-K audio power amplifier and a new audio chip that significantly reduces TDD interference and EMI.
While megapixels no longer tell the story of cameras, they are still used to explain things. “A better CMOS” means it is better in some specific manner than the previous option. Is there a measurable difference? Is there a newer chipset? What is better than v1?
What is TDD and EMI in the audio? What is Class-K? What does v2 capture that v1 garbled in audio? Distance from mic improved? Less crackling? Higher/Lower range? Other?
