The Viper 791XV is a good alarm. Has the 2 way remote so that when the alarm goes off, it pages you, as long as you are close enough. Leave the siren unhooked, flashing lights unhooked, and buy yourself a gun [img]smile.gif[/img]
I just finished the initial install of a compustar 2wss-as in my 9C1. Very nice unit for $299 on ebay . This is the spread spectrum 2-way paging alarm with an advertised range of 1-1/4 mile.
At first I struggled but it was simply a matter of getting a good ground.
I finished late last night, left the car in the office garage in a concrete building with a standard commercial garage door and a steel rolling door (double doors). I could query the vehicle from 4 1/2 blocks away in my apartment, wow. I am very impressed with range.
Quality of the unit appears good, instructions lack hand-holding. But quite simple to figure out. Tough part is finding the correct vehicle connections. The FSM is a charm for that.
apparently lojak uses radio frequency tracking or triangulation, not as good as cellular and gps tracking. when i was digging around for my first car alarm purchase I found the mobile guardian to have superior functions at a very good price. It can notify you via email, cell phone, pager that your car is on the move. Then you can query the exact location on the web.
I'm in no way connected to the company or product, but I'm interested in getting a dealer license for my brothers company. Who wouldnt want to track their kids, their wives/husbands and keep a tab on their collector car.
