Our dedicated LED provides training and ongoing support to police agencies relating to the installation of our tracking solutions within local jurisdictions. Comprised of active and retired law enforcement officers, this division along with our 24/7 Tracking Support Center makes our tracking solution second to none. Over 7,000 Law Enforcement agencies utilize 3SI technology to protect their communities against crime. These police partnerships are key to helping reduce crime and catch criminals. The law-enforcement community is enthusiastic about 3SI Tracking, and as more law enforcement professionals are made aware of it and are trained in its use, our System’s applications continue to grow. Law Enforcement agencies themselves are increasingly becoming 3SI customers, integrating the Tracking Solution for tactical use in property crime situations with our Electronic Stake Out Solution.
