I have invested a tonne into a great sound system lately, and I'd like a better car alarm to protect it. So features I'm looking for are the following:

Radar outside and inside
Impact
Glass breakage
Pager

Basically, everything except for remote start, and sensors for doors, hood and trunk opening (which I already have, minus the trunk, but which should be set off by the impact sensor.

One model that was recommended to me is the Alpine SEC-150R.

Alpine is very good....... but I would also look into Viper systems, but I am not sure whether any Vipers come with the paging feature? Check them out though.
