Infra Red Beam (gate) Sensors - (don't be devided by their appearance they are about 40-50cm long). Beam Sensor Manual - PDF (0.79mb) These are the type of sensors that you find in shops and when a customer walks through the door a chime sounds. They can be used for different purposes such as boundary protection to alert you when someone enters your boundary or by the pool fence to let you know a child has entered the pool area. They use 433mhz to connect to Keriu systems, although you do need to supply external power to these which is a little annoying given they are outdoors and a distance away from my nearest 240v. As far as operation goes you just set them on their own group and set that group to either doorbell or welcome setting so when someone passes through W1 will make the 'Welcome' or 'Doorbell' noise which you can then check your driveway for activity.
