Don't know if anyone can advise but I need some kind of device that I can install across the entrance to my driveway that can detect when someone comes up the drive and sounds some kind of buzzer in the house.
Needs to ideally be some kind of wireless device as the end of the drive is about 400m from the house.
Anyone used such a device or have an idea of where I could source such a thing?
