DEI (Directed Electronics, http://www.directed.com/ )is the company that makes Viper alarms as well as a good number of other brands. They have been around for MANY years and have pretty much beaten everyone else out of the race when it comes to car alarms. Viper, Python, Sidewinder, Hornet and the list goes on, all made by DEI and all are pretty much the same. They acquired Clifford Alarms a while back, not sure if they now manufacture those alarms or not but I would stick with one of their top brand names (listed above). One important thing to consider is to NOT display the VIPER ALARM decal on your window, all this does is tell a thief what kind of alarm you have, making it a little easier on them. Also keep in mind that an alarm is simply a deterrent, anyone with some common sense can bypass an alarm (good thing most thieves are stupid thugs lol). As for false alarms, any brand can do this, if you have the sensitivity of the shock sensor set high then it will go off every five minutes....there needs to be a balance between how sensitive you want it and how sensitive it needs to be.
