I recently noticed this keypad on our front porch. As far as I can tell, it's not connected to anything. Does anyone know what it was for? A security system perhaps? Garage door?
My guess is that it is a security keypad. The DNS on the cover could be from D.N. Security Services, Inc. a company from Northern California that was acquired by Universal Services of America in 2009: http://www.universalpro.com/news2.html.
