I've been using the Yi Home camera for many years. But they are starting to have connection issue and won't recognize human and kept asking me to subscribe. Wasn't giving too much home to the to but since it said wifi 6 I figured why not? Worst case I'll return. I use tp link deco to build my home wifi mesh system, so tp is not unknown. It's also a big Chinese company like Yi (So if you have issue with China surveillance you then skip it). To my surprise it has even wider lens, and the low light performance is superb. I especially love the AI feature of human and pet recognition. All for free. The magnet mount comes in handy when you have metal cabinet or anything metal nearby. My only regret is I only bought 2 when it's on sale. Need 1 or 2 more.

Its great and meets my needs.

Is it 2.4G. 5G for both?

Compared to a Wyze camera, this device feels like junk. For the price, there is no color night vision, and it really doesn't perform well in low light. When viewing it at night, the image flickers, making it an unreliable camera. Overall, it seems like a cheap $10 camera.
