Innovation That Protects
3SI Security Systems introduced ESP®, Electronic Satellite Pursuit, in 2003. ESP remains the leading GPS tracking and apprehension tool for customers protecting cash and high-value assets from robbery and burglary in financial and retail establishments.
3SI offers further cutting-edge GPS tracking tools (Electronic Stake Out® and SNT Tracker®) exclusively to Law Enforcement professionals. These technologies apprehend criminals within minutes after a crime is committed. ESO®, Electronic Stake Out, is easily concealed in bait items enabling police to target and track offenders committing pattern crimes. SNT Tracker’s robust and durable housing is capable of withstanding harsh conditions for tracking vehicles or other large assets for extended periods of time. Learn more about 3SI Security Systems.
