I've been trying to research some low voltage motion sensors for a project i'm designing and coming up with few options. I'd like the fixtures to turn on independently. Also I'd like to mount these on the back of some stone walls within the landscape directed towards the lawn areas instead of around the eaves of the house. There will be approximately 7 fixtures around the perimeter of the house. The house sits in the middle of farmland with no other houses around. Any tips from experience would be greatly appreciated. I like this setup and it could be used with a Unique 24v transformer. http://www.wattstopper.com/products/details.html?id=108 And the ABT but there is little information on these as far as size and installation http://abtwireless.com/motion_control.html Are there any newer options?
