I took a very short video of the lights in the main garage in Wake Green Park.
A sensor notices when someone/a car is in the area, and full lighting comes on. Clever!
Obviously this saves energy when the garages are not in use, thus keep the 'green' in Wake Green Park! :)
PS. There's some quite nice birdsong in the background of the video! We have several bird boxes around the park. I'll blog about them soon.
