Viper 791XV 2 Way Alarm System w/ Remote Start
the standard in low-cost but GOOD security systems
This 791 is very similar to the more common and less expensive 350 and 426 models, you are mainly paying a lot more for the 2-way remote and extra bells and whistles like remote start.  Better to spend your money on adding say a battery backup accessory or a motion detector, IMO.<br /><br />Unless you own a Porsche or some other high-profile target for thieves, be aware that the most realistic function of a car alarm is the deterrent effect of the flashing light on the dash.<br /><br />Most car crooks are kids, homeless, junkies, and other amateurs who'll gladly move on to an easier, un-alarmed car; a determined pro will most likely still have his way with your car regardless.  So the top priority for most people in buying a car alarm is really just reliability, which Viper does very well.<br /><br />If you're looking for high-end, look at the Clifford alarms, they are now owned by the same parent company as Viper but they do offer more user-programming options. The hardware is of comparable quality, the Cliffords just offer more features.<br /><br />I have the Clifford in my sedan and the Viper in my truck. The Viper actually has a louder siren, but unlike the Clifford if I want to adjust the sensitivity of the glass breakage detector I have to take it back to the dealer whereas with the Clifford I can just do it through the remote.<br /><br />A tip: make sure that whoever installs your Viper puts it on \\"active arming\\" mode instead of \\"passive arming\\" which will drive you crazy because it will automatically arm the alarm every time you close all the vehicle doors.<br /><br />These are still way better than the no-name cheapo alarms coming out now at Best Buy and other places.  And please don't cut corners on the install, it involves cutting into your car's electrical system so you want somebody who knows what they're doing.
