According to Charlie Quong, Director of Product Development for
Security and Remote Start, "The results have been phenomenal so far.
All test units in the field have achieved or exceeded the range
target of one mile. Responder SST with Spread Spectrum Technology is
on track to ship in August, just in time for remote start season."
Remote start, a technology that allows consumers to start their
engines and warm up their vehicles by remote control, continues to
grow in awareness and popularity, particularly in the cold weather
regions (though it can also be used to pre-cool vehicles during hot
weather). Range from the keychain remote control is important. For
the product to be effective it must be able to remote start the
vehicle when it is parked down the street, or at the far end of a
snowy parking lot.
Award-winning 2-Way Responder systems from Directed, marketed
under the Viper, Python and Clifford brands, have been best-sellers
for several years, allowing users to stay in touch with their
vehicles from up to one-quarter mile away. A true 2-Way transceiver,
the Responder remote allows the user to send a command to the
vehicle (i.e. arming the security system or starting the engine) and
then receive confirmation back. The remote also acts like a pager,
notifying the user by beeping or vibrating when the security system
siren is sounding.
However, the latest generation Responder SST products, which
recently achieved formal FCC approval, use Spread Spectrum
Technology to achieve range of up to or exceeding one mile,
employing digital frequency hopping and multiple frequency
transmission to assure that, if a frequency is blocked, the signal
still goes through. Responder SST also uses dual error correction
systems to combat signal data corruption and minimize signal
According to Jim Minarik, Directed Electronics President and CEO,
"Digital Spread Spectrum Technology in all its configurations
represents Directed's ongoing commitment to our customers to
continuously improve our industry leading products and services. We
are truly Driven to Excel."
