Nest Hello uses HDR, which helps lighten shadowy areas while not blowing out bright areas. Sometimes the video looks a little artificial as a result, but the point is that you get a good look at everything in the frame, which is just what you'd want from a doorbell camera. When you're looking at the live view on your smartphone or tablet, you can pan and zoom using your fingers right on the image. The lens is fixed, so it's just digital panning and up to 8x of digital zoom. This is nice to have just in case you need it, but the default wide view was detailed enough for me. Two way audio lets you talk to someone at the doorway with about a second of lag.

Also, you would have another problem of making sure that the batteries were always charged and in working condition. It would really funny if power actually did go out and then your back up battery system conked out because they were not charged. Also consider your level of technical expertise and mechanical ability. If you are someone who likes working with their hands and enjoys putting something together, then you may have more options than someone like me. Personally, I am not mechanically inclined so I never really intended to build or put together my makeshift system at all. On the other hand, you may be surprised to find out just how simple and easy to install some of these modern cameras really are. I have put in at least 20 different types of cameras all on my own. Some were a bit difficult, but most were surprisingly easy and simple. Usually the instructions were very clear. The times when it became difficult, I was able to jump online and check out some plans, instructions or even videos to guide me through the difficult parts. My point here is that you may actually surprise yourself with what you can do when you put your mind to it.
