When you walk in day or night time from the side it’s no problem. The problem is movements in front of the camera. When you walk straight to the camera there is no detection. I hope they can fix it in a software update.
The video quality is great.
My recommendation for the night: why they use the visible red dot ultraviolet nightvision? It’s looks a little cheap and I think because you noted the camera you steel it or break it.
Tip: check first with nightshot off, maybe there is enough light. When it’s possible get a light because without the camera is 50%. better.
