What’s New? SecuriDab® LT

SecuriDab® LT

Our newest product, SecuriDab® LT (SD LT), offers a universal, innovative and flexible system for markets without specific banknote degradation requirements. Based on the highly-successful SecuriDab product, the lid-based LT version offers reliable staining performance at an economical price. SD LT can detect a variety of types of attacks including unauthorized opening, pull out, break-in and drilling or cutting. After detecting and verifying the attack, SD LT stains the notes rendering them worthless to the criminals.

Cash Protection Products

Cash protection products

Scorpion®, SecuriDab NG™, SecuriDab® LT and SecuriSafe ATM™ are all sophisticated systems that have proven to protect cash stored inside ATM cassettes and similar cash machines during physical attacks. Scorpion and SecuriDab NG are robust cash-staining systems offering very consistent and reliable performance and are successfully protecting thousands of cassettes around the world in homologated markets and outside. SecuriDab LT (or SD LT) is a lid-based system designed as an economical alternative for non-homologated countries. SecuriSafe ATM™ detects an attack and releases large amounts of red smoke, which both obscures the criminal’s ability to continue with the theft and draws unwanted attention to the ATM attack.

Explosive gas attacks against ATMs have become commonplace. To counter these threats, 3SI offers AGN® or Autonomous Gas Neutralization. This advanced system detects the presence of explosive gas and releases deterrent substances to mitigate any explosion and render the explosive gas completely ineffective.

Tracking Products

Tracking products

For over 10 years, 3SI’s GPS Tracking systems have recovered stolen cash and products, and have helped apprehend thousands of dangerous criminals. Using a patented design comprising three technologies (GPS, Cellular and RF), products like our Cash Tracker™ and ATM Tracker™ track stolen property and report to our secure website. Security companies and police receive detailed tracking information to pinpoint and catch the criminals. With over 70,000 trackers installed worldwide, 3SI has the experience to protect your cash and valuable assets.
