If it detects motion, it'll tack the contents of that buffer onto the start of your alert clip, so you get a fuller picture of what's happened outside your house. One big, er, plus to the Plus variant of the Video Doorbell 3 is its pre-roll functionality, which captures a four-second loop of lower-resolution black and white video using a second sensor. Angling the doorbell can be useful to point the camera or even just the motion detector away from a busy road, say the wide-angle lens means you'll see who's at the door, though. Given that, it's important to note that the Video Doorbell 3 includes two wedge mounts (one for angling horizontally, one for angling vertically), but you'll need to buy wedges separately if you want to angle the Gen 2, though they're not too expensive. You could juggle those teensy variations around in your mind based on where the doorbell is going to be positioned, but the difference is so minor that an angled mounting bracket is likely to make a much bigger difference to what you can see. If you're thinking of picking one of these video doorbells simply on the basis of its viewing angle, don't.
