August Smart Lock replaces or supplements traditional keyed entry with a smartphone app that can extend guest access, log visits, and keep home safe from anywhere. I think this is an incredibly convenient tool to use — there is activity monitoring which tracks activity and allows the home owner to know who is coming and going at the doorstep with a 24/7 activity feed. Users also have a total control of the door, locking and unlocking using the phone. Users can also grant unlimited digital keys that are available for a specific time frame that you set. It provides smarter and safer home access!
