Exclusion and inclusion zones are the backbone of most monitoring conditions — but how they're set up, and what happens in the seconds after a boundary is crossed, is often misunderstood. Here's how it actually works.
Exclusion zones vs. inclusion zones
An exclusion zone is an area a participant is not allowed to enter — a victim's neighborhood, a school, a specific address. An inclusion zone is the opposite: an area a participant must stay within, such as during house arrest. Most cases use a mix of both.
How a zone is set up
Officers draw a zone directly on a map in the Officer Dashboard — a radius around a point, or a custom shape for an irregular boundary. Each zone can carry its own rule: a hard alert on entry, a grace period before an alert fires, or a scheduled window when the rule doesn't apply.
What happens in the seconds after a crossing
- Detection — the device reports a position inside (or outside) the zone boundary in real time.
- Confirmation — the system checks the reading against GPS accuracy to rule out a false positive near a zone edge.
- Alert — a confirmed violation reaches the monitoring center and the assigned officer, typically in under 60 seconds.
- Record — the event, its exact time, and the participant's location are logged permanently to the compliance record.
"The grace-period setting alone cut our false-alarm callbacks by more than half. It's a small feature that changes how much you trust the system." — Compliance Officer, county probation department
Setting this up for your program
Zone rules are configured per participant, so a single program can mix hard-alert exclusion zones with more flexible inclusion windows depending on the case. Our team can help set up your first zone templates during onboarding.
