Responder Systems from Viper are simply the most advanced 2-Way Security and Remote Start systems in the world! The interactive display on the Responder remote confirms all commands - virtually instantly - with easy to understand icons, plus text! It alerts users to security system triggers by beeping or vibrating when out of audible range of the siren. And of course the 791XV and 591XV will start your vehicle with the push of a button, and you'll get confirmation back that it started, from up to one-quarter mile away.
