Bests & Worsts Reviews from Amazon

I previously purchased the 1080P unit and now this 4pc 720P set and I couldn't be happier. I myself have 2 Nest Cam set up in my house but I had to pay $150 to have the 7day video capture package ($100 + $50 for each add'l cam per year. OUCH!). These Yi units take micro SD card up to 64GB and it's way sufficient for my use. I purchased these to keep an eye on my aging parents and if I were to start fresh, I would certainly get these over the Nest camera. The Yi UI was easy to set up. I've configured it a few times, e.g., use my mom's phone as the main source and shared it with me and my dad, I reconfigured it so I'm the main user and shared it with parents, etc., with no error whatsoever, although you do need to reset the cam with a push of a button on the back of the unit, no biggie. The 1080P version has better audio and video, but for my parents' everyday use, the 720P met their expectations. What's nice about the Yi cam is that once I set it up on my phone (with the SD cards installed on the 2 cameras), I can then share all footage with both my parents (separate phones). One of the features I love is that I could also grant them permissions to view all history and allowing them to watch videos from the microSD cards. I also set up hotspot/motion detection so whenever there's movement in certain areas, they'll get notified and could check the Alerts to view the 6sec clip, and also the full on captured video from the SD card. Again, you can do all this without paying a monthly cloud storage fee!!! The Yi app is very easy to use. One thing that's missing is a web UI, but again, the phone app is more than sufficient for our use. The app is comparable to the Nest app if not better! I bought these on sale at around $96 for 4 units. That's less than the price of 1 Nest cam. *sighs* Again, these cameras have met all my expectations and I couldn't be happier. Highly recommended.
