The Mobotix Dual Lens Dome D15 camera is perfect for capturing a wide angle view of the entire lot and docks.  This camera is mounted on a light pole in the yard and transmits video signal via a wireless antenna mounted on the pole to an antenna mounted on the building.  This solution eliminates the need to trench cable under driveways and is a very cost effective way to position the camera in the location it will be most useful.
