Zone Entry

An event generated when a tracked tag enters a defined geofence zone. Triggers alerts, logs events, or initiates automated actions based on configured rules. Common use cases include access control, process verification, and safety monitoring.

Zone entry in industrial RTLS is a specific type of zone detection event that triggers when a tracked asset or person transitions from outside to inside a defined geographical zone boundary.

Technical considerations for reliable zone entry detection include: positioning accuracy determining minimum reliable zone size (UWB's 30cm accuracy enables zones under 2 meters, BLE's 3-5m accuracy requires zones 10+ meters), update rate affecting entry detection latency (1 Hz updates detect entries within 1 second, 10 Hz within 0.1 seconds), boundary buffers preventing false entries from positioning uncertainty (boundary placed 1-2× positioning accuracy inside actual physical boundary), and entry confirmation logic requiring sustained presence vs. momentary detection preventing false triggers from positioning jitter. Zone entry analytics provide operational insights: entry frequency measuring how often zones accessed (high-traffic vs. low-traffic areas), entry patterns revealing when zones typically accessed (hourly, shift, or daily rhythms), entry authorization compliance tracking percentage of entries by authorized vs. unauthorized personnel, entry-exit matching verifying all entries have corresponding exits (detecting incomplete workflows or security issues), and entry timing distributions showing typical arrival times supporting capacity planning. Best practices for zone entry configuration include: zone sizing appropriate for positioning technology (3-5× positioning accuracy minimum), entry confirmation thresholds requiring 2-3 consecutive position updates inside boundary before confirming entry, boundary placement accounting for positioning uncertainty (margins around actual boundaries), temporal filtering requiring minimum dwell time (5-30 seconds) before confirming intentional entry vs. brief incursion, and alert prioritization distinguishing critical entries (safety violations) from informational entries (workflow tracking).
