No Omega Excalibur ATV1000 with the Omega ECHO (two way) upgrade... As far a the windows, its just one of Omega's add on modules...
IMO if your looking for a Alarm the Excal's are the best... They have a ton of add ons, and aren't to bad to install... I maybe had 2 1/2 hours in Scott's. If you have any questions about that sorta stuff let me know...
