Southern Technologies

Sentry System
Introduced in 1986 as the company's first detector offering. This model was available both as a hot bearing-capable unit (blue in color) and a non-hot bearing-capable unit (black in color). Common users include Conrail, Norfolk Southern, & Southern Pacific.

SmartScan NG
Built upon the proven success of the Sentry System, the SmartScan Next Generation (NG) started production in 2004. Featuring dual processors and networking capabilities to back office systems, as well as the ability to integrate with an AEI reader, it is a substantion upgrade over its predecessor.

SmartScan NG²
Introduced in 2017, the latest generation of hot bearing detector includes significantly upgraded processors and a computer sythesized voice. Its improved processing capabilities allow for trains of over 4,000 axles to be scanned, and its modular structure makes for a very simple upgrade of an existing SmartScan NG site.

A non-hot bearing-capable unit that can be utilized for dragging equipment, high & wide loads, high water detection, wind speed, ambient temperature, and much more. It can also be used as a DTMF switch or grade crossing controller, switch position monitor, or an annunciator for a WILD detector. It also features the same advanced networking capabilities to back office systems as its SmartScan brothers. The iCUBE was introduced in 2014.

Small Talk
A very basic talker unit designed to allow easy & economical replacement of older non-hot bearing capable models. Not nearly as feature-rich as the iCUBE, although it does support transducers for axle counting.
