We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from Roger, who is just about tired of hearing "ADT." If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"I'm moving into a new place, and I need a good wireless home security and fire system. But here's the thing -- I only have a broadband internet connection and a cellphone. I can't use one of those traditional ADT systems that require a landline, and moreover, the $40+ per month they charge is outrageous. I need a DIY option that monitors both security and fire, and I'm fine paying up to $25 or $30 a month for UL-certified off-site monitoring. SimpliSafe and Lifeshield seem decent, but the former doesn't monitor fire yet. Support for live feeds and alerts on my smartphone would be a huge plus. Thanks!"

Looks like SimpliSafe will be the perfect solution when it adds fire support in 2012, but Roger needs help in the here and now. Any paranoid homeowners out there have any other awesome suggestions? Drop 'em in comments below!
