MOST alarms are made by the same company...DEI
they make viper & clifford
Directed Electronics - Security & Remote Start
i have the sst5900, 2way paging/confirmation (so if i send a
"command" via the LCD remote i get confirmation that the the
command was recv'd and the truck is started or shutdown)
the remote range is 1mile (line of sight)....the truck will
also periodically communicate w/ the remote to alert you if
there have been "zone" violations (door open, hit/bumped or
broken window)
the alarm also has starter interupt (if the alarm is tripped the
truck can not be started).
i like the remote start (turn the heat on before i shut the truck off
and ill have heat when i start it in the morning...air condition same way)
i have it programed for 15min of "remote start/run" time and 3min. of
"cool down" time.
1 year ago (feb 07) I paid 450 <including installation> for the
viper sst5900...ymmv, the alarm cost a dealer about 250 bucks.
