shopping for a security system

I performed a search using several terms and could not find anything relevant, so I am posting in this section. I'm looking for a remote start system with alarm that has the ability to monitor via the LCD remote the vehicle's interior temperature AND battery voltage (the vehicle's battery, not the one in the remote). So far, the only systems I've found are the Compustar Pro ones. There are no installers within 50 miles of me according to their website, and they are not for sale to individuals. I plan on a DIY install into an early 90's Dodge passenger car with manual transmission. I don't need a lot of bells and whistles otherwise. Is there another company that offers this set of features on the remote? I've spent a lot of time reading online install/owner manuals from several companies without any success. Thanks for any advice.

The new Responder LE models from Viper and Clifford will monitor the cabin temp and display it, but it won't display the battery voltage.  It will however, monitor the battery voltage and if it gets too low, it will automatically start the car to charge the battery.  The voltage threshold is set by the Bitwriter programmer. 

Thanks for the info, I'll look at it.
