Officer safety
Help arrives where it's needed, fast.
- Duress button sends the officer's name and exact location
- Alerts when people enter areas they shouldn't or groups gather
- Live location of every officer and person in custody
Modernize corrections supervision
Protect your officers. Counter contraband. Free up the shift.
Every person in custody wears a tamper-detecting iLink tag. Every officer carries a duress device. Sensors across the facility feed one live dashboard, so staff know where everyone is, who they were with, and who needs help.

The problem
Fewer officers, more contraband, and rising risk for everyone inside.
Agencies are asked to do more with fewer people, while the dangers to officers and to people in custody keep growing.
Staffing
23%
fewer correctional officers employed by state governments in 2023 than in 2012, leaving fewer eyes on the floor.

Workload
And the work itself hasn't changed. Counts, searches for people, and handwritten logs still take hours every shift, hours that should go to supervision.
What iLink does
One platform for officer safety, contraband, workforce efficiency, and wellbeing.
Each person in custody wears a secure, tamper-detecting iLink tag, and officers carry a safety device that can be belt-worn or worn as a lanyard. Staff see everything in a browser, and training takes under an hour.
Contraband control
See how contraband moves, and who moves it.
- A record of who was near whom, and where, for every incident
- Location history that helps trace contraband to the people behind it
- Alerts when known rival gang members are together
Workforce efficiency
Hours of manual work, handled automatically.
- Continuous automated headcounts that cut count time by 50% or more
- Meals, medication, programming, and movement logged
- Records ready for investigations, audits, and records requests
Wellbeing in custody
Safer, healthier days for people in custody.
- Proximity records support keep-separates and PREA investigations
- Fewer stand-up counts and unit searches
- Liveness and vital-sign alerts for possible overdose or illness
How it works
Four parts, one live picture of your facility.
DIG installs and maintains everything. Your staff only need a browser.
-
01
A tag on every person in custody
Secure, waterproof, and tamper-detecting. Worn on the ankle.
-
02
Sensors across the facility
Placed throughout buildings and grounds by DIG, on a network separate from yours.
-
03
DetectCenter in any browser
Counts, locations, alerts, and reports update on their own, and central office can see every facility.
-
04
An alert to the right officer
Alerts reach the staff who need to act, and every officer carries a duress device, worn on the belt or as a lanyard.
Capabilities
Everything in one tag.
Each iLink tag takes the place of a stack of manual checks, paper records, and ID cards.
-
Automated headcount
Continuous roll calls, without interrupting activities, that name anyone not accounted for.
Efficiency -
Investigations support
Names everyone near an event, to match against video and trace contraband.
Contraband -
Location tracking
Near real-time location by unit, with alerts for restricted areas and gatherings.
Safety -
Officer duress
A button on the officer's belt or lanyard sends their name and location to responders.
Safety -
Pharmacy records
Medication receipt recorded against each person, through your pharmacy system.
Wellbeing -
Commissary ID
The tag serves as each person's ID for commissary purchases, through your commissary vendor.
Efficiency -
Electronic ID and access
Each person's tag is their ID at meal lines, doors, and checkpoints. It stops double servings and ID swapping, and gives people a reason to keep the tag on.
Efficiency -
Liveness and biometrics
Heart rate and body temperature confirm the wearer is alive and flag distress.
Wellbeing
What your staff see
The whole facility, live, in one browser tab.
Counts, alarms, and locations update on their own. Staff act on what needs attention instead of collecting it by hand.

Results
Like having more officers on every shift, without new hires.
When counts run on their own, the hours officers spent counting go back to supervision.
At a 2,000-bed facility
Automating half of the daily headcounts frees about 120 officer-hours a day. That's the equivalent of:
+21more full-time officers on your roster
+5more officers on duty on every shift, around the clock
−$1Ma year saved in base wages you would otherwise spend to hire them
Based on 6 daily counts (3 automated), 20 staff-hours saved per count per 1,000 beds, 2,080 hours per position, and $23 an hour base pay.
In the field
Results from real facilities.
An alert that known gang members had entered an area they didn't belong let an officer break up the group before violence occurred. They were carrying weapons.

An officer used iLink location data to identify the people making alcohol inside the facility.
Contraband
See how contraband moves, and who moves it.
Location history and proximity records show who was where, and with whom. Investigators can trace contraband to the people behind it, and staff are alerted when people gather or enter areas they shouldn't.

Wellbeing in custody
Safer, healthier days for people in custody.
The tag that counts and locates also helps keep people apart who shouldn't be together, keeps an accurate record of each person's day, and watches for medical distress.
Safety
Protection from violence
Alerts when groups gather or someone enters an area they shouldn't, and a record of who was near whom supports keep-separates and PREA investigations.
Fairness
An accurate record of every day
Out-of-cell time, meals, medication, and programming are logged automatically, so the record holds up to standards reviews and grievances.
Less disruption
Fewer stand-up counts and searches
Automated counts can replace some manual counts, and staff can find a person without searching the unit.
Health
Early warning on medical distress
Liveness and vital-sign monitoring flags possible overdose or illness, so staff can respond sooner.

- Officers are trained
- Tags go on, and you go live
Modernization
Digitizing paperwork isn't modernizing.
Many modernization projects put the same manual work on a tablet. The records move online, but officers still walk the count, search for people, and fill in the logs. iLink changes the work itself.
The usual approach
Digitized paperwork
Same manual work, now on a screen.
- HeadcountsOfficers walk the unit and enter the count on a tablet
- Finding a personRadio calls and searches
- Officer in troubleA radio call, if the officer can make one
- Activity recordsTyped or scanned by staff
- WellnessScheduled checks, logged after the fact
Real modernization
With iLink Automated
The work happens on its own.
- HeadcountsThe count runs continuously, and anyone missing is flagged by name
- Finding a personLive location, with an alert when someone is out of place
- Officer in troubleA duress button that sends the officer's name and exact location
- Activity recordsMovement, meals, medication, and programming logged automatically
- WellnessAlerts on missed liveness or abnormal heart rate as they happen
Track record
Built by the team that created GPS offender tracking.
The people behind DIG fielded the first GPS tracking system designed for offenders in 1995, then grew that company, Pro Tech Monitoring, into the market leader before its acquisition by 3M. iLink brings that experience inside the facility.

Privacy and oversight
Clear answers on data, access, and oversight.
Agencies, oversight bodies, and families ask good questions about what iLink records. Here are the short answers.
What does iLink record?
Each tag reports its location and its status, including tamper alerts. The system also logs alarms, meal and medication events, and the vital-sign readings used for liveness and wellness alerts. It does not record audio or video, and it does not capture the content of calls or messages.
Who owns the data?
The agency does. DIG hosts it in Microsoft Azure, encrypted, and iLink runs on its own network, separate from the facility's.
Who can see it?
Only staff the agency authorizes. Access is role-based, so each person sees what their job requires.
How long is it kept?
Retention follows the agency's own records schedule.
Does iLink replace officers?
No. It takes counting, searching, and paperwork off officers' plates so they can spend that time supervising people and responding when someone needs help.
