We used to sell DEI electronics. Its a great company. They make a lot of different alarms. I have the equivalent to the viper...its their python series 2 way paging unit. Basically the same unit, not as much color in the display screen, in fact most of the wiring harnesses are compatible to each other. Mine has a few less features then the big brother Viper, but the 2 way is nice. It gets annoying if the sensitivity is to high and you live in a city or a loud place (Air Force base). Its a balancing act on setting the single stage or pre-stage warning. I loved the remote start feature the most!
