This works exactly like it should. Initially I was concerned about it being battery powered but it has been great. It records 99.9% of all comings and goings - bearing in mind it is not meant to be a full-blown security camera. And it has survived some pretty wild weather given that is in an exposed location. I have used it to answer the door as well and two-way communications worked - albeit with a minor lag. All in all I'm very happy.
