Eliminate wasted trap checks and take full control of your pest operations with Owl Sentry — built by a team that spent years in the field and knows the pain of checking empty traps. With Owl Sentry, your traps become smart, connected devices that work for you around the clock: ‣ Get instant push notifications the moment a trap catches a pest, bait runs low, or a station requires service — no more driving to empty traps. ‣ Monitor all your traps in real time on an interactive map with live status indicators across every location. ‣ Attach retrofit IoT sensors to any existing trap in under 2 minutes — no new equipment or rewiring needed. ‣ Start, track, and complete service visits directly from the app with NFC check-in for on-site proof of work. ‣ Access full activity history for every trap — catches, bait consumption, pest migration patterns, and technician visits. ‣ 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 — eliminating false positives and unnecessary site visits. Built for the field: IP68 waterproof, 5–10 year battery life, operating from -20°C to +60°C, with a 2-year warranty on all hardware. Customers report up to 5× reduction in operational costs, 70–95% fewer wasted visits, and 3× higher technician productivity. Owl Sentry requires an active subscription and compatible sensors. Starter kits and custom orders available at owlsentry.com.
