With Owl Sentry, your traps become smart, connected devices that work for you around the clock: β€£ Get instant push notifications the moment a trap catches a pest, bait runs low, or a station requires service β€” no more driving to empty traps. β€£ Monitor all your traps in real time on an interactive map with live status indicators across every location. β€£ Attach retrofit IoT sensors to any existing trap in under 2 minutes β€” no new equipment or rewiring needed. β€£ Start, track, and complete service visits directly from the app with NFC check-in for on-site proof of work. β€£ Access full activity history for every trap β€” catches, bait consumption, pest migration patterns, and technician visits. β€£ Manage multiple locations and hundreds of traps from a single dashboard, with auditor-level access for compliance reporting. Owl Sentry sensors use long-range LoRaWAN connectivity (up to 4,500 ft) and AI-powered double verification to ensure you only respond to real events β€” eliminating false positives and unnecessary site visits. Built for the field: IP68 waterproof, 5–10 year battery life, operating from -20Β°C to +60Β°C, with a 2-year warranty on all hardware. Customers report up to 5Γ— reduction in operational costs, 70–95% fewer wasted visits, and 3Γ— higher technician productivity. Owl Sentry requires an active subscription and compatible sensors.
