We have a gate 100 meters from our house and want to know when someone is entering our property (when we open the gate leave open) or if they are standing at the gate and need to be let in (if we want). So it alerts us and we can look at the camera to see what's going on. We already have one and it works great. So we bought this new one for the store so we can hear when a delivery arrives or a guest arrives or whatever is in the store.
