For the G3/AFs, you feed the wire into the mount, which is tight especially if you're not aiming straight ahead (which I assume few people are doing). The Flex gives you more leeway, but because the cameras are inexpensive, the wall mounts for them are reflective of the cost savings, which means "not great". The motion sensing is quite sensitive and there's no machine learning behind the analysis like there is with Nest. I prefer the Unifi Video's motion sensing set up over that of Zoneminder which I was using before. I find myself creating less-sensitive motion sensing zones where I know there are plants/trees that are going to blow plus where they might cast shadows. The "before" and "after" settings for motion detection are pretty important if you think your footage is getting cut off at the beginning or the end of the clip. I use a setting of 5 seconds. Since I came from crappy wifi IP cams, I've been very happy with my setup. I'm currently using an inexpensive NUC as my Unifi Controller and NVR. I have four cameras recording on motion sensing (the others are for monitoring only). The only time I have issues is when I run Duplicati in the background to backup the video files to a NAS. Duplicati is a bit of a pig, but I'm not a Linux expert, and Duplicati was familiar and easy to set up. From everything I've seen and heard, Nest is great, but I find the subscription fees to be excessive, but ymmv based on your own needs.
