Alcohol Monitoring

With optional house arrest monitoring. Continuous Alcohol Monitoring (CAM) is the most technologically advanced alcohol monitoring system in the world. Worn 24/7, automatically samples a client’s perspiration, every 30 minutes, to measure for alcohol consumption. No missed tests. No circumventing a testing schedule.
With EMS Tether, the world’s most widely used and trusted 24/7 transdermal alcohol testing system, for use with high-risk, hardcore DUI alcohol offenders. It combines 24/7 alcohol testing with optional house arrest monitoring in a single device.

Remote Breath

Introducing Remote Breath, the most flexible option in breath testing for lower-risk alcohol clients.
Remote Breath is the first and only handheld, wireless, portable breath alcohol device with Automated Facial Intelligence™.
The world’s first handheld, wireless, portable breath alcohol device with automated facial recognition and GPS with every single test. For your lower-risk offenders or those who have earned less intensive testing and monitoring.
