Ordered into monitoring?

Here's what to expect.

If a court, probation officer, or pretrial services program has ordered you into alcohol or GPS monitoring, we know the process can feel confusing or stressful. Our job is to make it straightforward: we come to you to fit your equipment, walk you through exactly how it works, and keep you in compliance so you can focus on everything else in front of you.

You don't need to find your way to an office. We install at your home, or at the jail if you're being released directly into monitoring, any time of day — including evenings and weekends. We coordinate with your supervising officer or court so your compliance reporting happens automatically in the background.

What you'll need to get set up

✓A copy of your court order or monitoring conditions
✓Your supervising officer's contact information
✓A valid ID and a way to reach you (phone or email)

Our services

Monitoring equipment for every requirement

We fit and support each of the following, matched to whatever your court order or supervising officer requires.

GPS location monitoring

A lightweight, waterproof ankle device that provides continuous location tracking around the clock, so your compliance with curfews, exclusion zones, or travel restrictions is documented automatically.

Worn 24/7 Waterproof Real-time alerts

Continuous alcohol monitoring

A discreet ankle bracelet that samples perspiration through your skin to detect alcohol consumption automatically, with no need for scheduled testing. Results report directly to your case file.

24/7 sampling No scheduled tests Tamper detection

Portable breath testing

A handheld breathalyzer unit for scheduled check-ins, with photo confirmation to verify it's really you testing. Ideal when your order calls for set-time testing rather than continuous monitoring.

Scheduled check-ins Photo confirmation Portable

Home curfew monitoring

A body-worn device paired with a home base unit to confirm you're where you're required to be during curfew hours, with automatic notification if you leave the covered area.

Equipment details

What each device actually does

All of our equipment is professional-grade, built for continuous wear and real-world conditions — here's what's actually inside each one.

GPS location monitoring

Worn on the ankle, this device combines cellular, Wi-Fi, and RF signals so your location keeps reporting even in areas where GPS alone struggles — meaning fewer gaps and fewer false "lost signal" alerts.

CoverageDual-SIM cellular + Wi-Fi + RF for continuous signal

BatteryMulti-day life with wireless on-body charging

BuildWaterproof, tamper-resistant strap with breach alerts

ComfortLightweight design rated for long-term daily wear

Continuous alcohol monitoring

This ankle-worn device reads alcohol consumption through the skin automatically, all day and night, so there's no schedule to keep track of and no test to remember. Readings are compared against ambient conditions to rule out false positives from things like hand sanitizer or cleaning products.

SamplingContinuous transdermal readings, 24/7

AccuracyCompensates for ambient/atmospheric alcohol exposure

SizeOne of the smallest combined alcohol + GPS devices available

MaintenanceMinimal upkeep, wireless on-body charging

Portable breath testing

A handheld unit for scheduled check-ins rather than continuous wear. It confirms your identity with a photo at the moment of testing, so results can't be disputed or faked, and results transmit immediately rather than waiting on a manual report.

Identity checkPhoto confirmation with every test

Battery48+ hours between charges

CommunicationTwo-way voice and text built in

PortabilityHandheld, no home base station required

Home curfew monitoring

A small body-worn tag communicates with a base station installed in your home to confirm you're present during your required curfew hours. If you leave the covered area during curfew, or the base station loses contact with the tag, it's flagged immediately rather than discovered later.

Tag batteryMulti-year rechargeable battery life

Backup power48-hour battery backup in the home base station

DetectionMotion and tamper sensing on both pieces

SetupSimple plug-in installation, no landline required

For courts, agents & attorneys

Real-time visibility into every case

Every client on our program is tracked through a live case management platform, so you're never waiting on a phone call for a status update. You can see strap-on confirmation, device battery level, and last-check-in time for each person on your caseload, organized by county, updated in real time.

If a violation or tamper alert happens, it's flagged instantly rather than surfacing in a weekly report. That means faster response when it matters.
