ESO® (Electronic StakeOut®)

Provides Law Enforcement With Tracking Technology to Stop Crimes

While tasked with solving more and more crimes, Law Enforcement agencies are facing issues of lower budgets and fewer officers. To expand on agencies’ capabilities, Electronic StakeOut® (ESO®) offers a device to increase efficiency in tracking and apprehending criminals committing pattern crimes. The newly updated 4G ESO® combines various location-based technologies (GNSS, WiFi, Cellular, and RF) in a single reusable tracking device designed to be easily hidden within frequently stolen items. Officer safety enhances by providing an improved awareness of the situation when the crime occurs.

A highly effective system allowing law enforcement officers to arrest felons within minutes after a crime is committed, this apprehension tool is a must-have for crime prevention units.

Successful ESO operations have helped solve crimes including:

  • Package theft from front porches;
  • Laptops stolen from cars;
  • Bicycles stolen in cities and on college campuses;
  • Copper wire taken from building sites and abandoned buildings;
  • Truck tire theft from parked rigs;
  • Controlled substance narcotics taken in pharmacy robberies;
  • And many more!
