It is excellent with motion detection, video quality and two way speaker. One real advantage you have buying the corded version is that you can also put a battery in it for in case of power failure or if you want to tuck it away in a spot temporarily while some contractors are doing work or what have you you can do it. All you have to do is buy the battery separately. When plugged in it charges the internal battery as well you don’t have to do it separately. They don’t tell you this!
