[Employee of bestbuy] Great product. Ties into the doorbell to allow access easier to unlock the door. This one has the had reader and a key pad. There is another with the doorbell and a camera as well in the same unit. I have a doorbell with the two cameras so it was not needed. Battery is proprietary to the unit and rechargeable. There is a smaller backup battery built into the cover panel on the lock side. Guess this is for when the main battery dies you can still open the door with the keypad? Battery seems to be lasting a good amount of time. 5 weeks and still at 90% Had one hiccup. The reader would not activate when hovering my hand over the reader. Typed in my passcode and it worked. Once inside, I pulled the cover and power cycled the device by pulling the battery. Has worked evey since.

Amazing!! Vein detection works great. Install was simple. Took about 3-5 minutes with a friend. Battery last long, and has additional back up battery option. Love this !! The app is stunning as well !!! I get lots of compliments. It self locks on a timer as well if your hands are full. Just close the door. It will deadbolt automatically :)

This device works very well as a standalone unit that doesn't require a home base. While the home base does provide faster access, I specifically chose this model so my kids can see outside on the screen without opening the door or checking. Two areas for improvement are clear: with a faster connection, loading times can occasionally be longer, and there isn’t a way to hide the door’s frame. Overall, it performs even better with a home base. I also purchased an extra battery to ensure there’s no downtime when the battery runs low.
