I am in the market for a new alarm for my car that was recently stolen.I had a dei product in it but it failed so im looking into these does anyone have experience with these?and if so what kind of options can be put into it ::EX..external perrimiter::

 

First I would be willing to bet the failure of the DEI was due to install rather then the alarm.

The Compustar alarms remote starts and their alarm/remote start combo unit's are very good, [we are both a DEI (Viper) and a Compustar dealer]... http://www.compustar.com/ they come with a dual stage impact and have an extra dual stage input.

Also have the best 2way range of anything I have seen. 94
