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.

The wayback machine only has the first letter of their logo, but it looks like it matches: web.archive.org/web/20030909151808/http://… (their web page from 2003). I believe this is the right answer. – gregmac Dec 2 '10 at 2:06
Logo seems different here crunchbase.com/company/d-n-security-services – Saxtus Dec 2 '10 at 5:53
@Saxtus: that's why I went back to the Wayback machine, it looks like they changed their logo a few years ago, before they were acquired by Universal Services. – gregmac Dec 2 '10 at 15:26

Looks like a wireless garage door keypad.

You could try taking it down and seeing if you could put new batteries in it... – Chris Jaynes Dec 2 '10 at 14:13
