Security Camera AI Detection: Person, Vehicle, Package, and Animal Recognition

AI object detection transforms a security camera from a motion sensor that triggers on any movement into a sentinel that alerts only on relevant events — a person approaching the door, a vehicle in the driveway, a package delivered and later removed. The classification accuracy, the range at which objects are reliably identified, and whether the AI runs on-device or in the cloud determine whether the camera's notifications are useful or ignored.

Person detection is the most mature AI category and the most critical. Modern cameras achieve >95% accuracy for person detection at ranges up to 10–15 meters in daylight, dropping to 80–90% at night under IR illumination where the lack of color and reduced contrast make human form classification more difficult. The Eufy SoloCam S340 uses on-device AI that processes person detection locally, eliminating the cloud dependency and latency of cloud-based detection. False positives for person detection typically involve objects with human-like proportions — a coat rack visible through a window, a shadow cast at a specific angle, or a large dog standing on its hind legs. The practical mitigation is to adjust the detection sensitivity and mask regions of the frame that contain persistent false-trigger objects.

Vehicle and package detection are newer AI categories with lower accuracy than person detection — typically 85–95% in daylight, 70–85% at night. Vehicle detection is useful for driveway monitoring: alert only when a vehicle enters the driveway, not when a person walks past on the sidewalk. Package detection, popularized by Ring and adopted by most competitors, identifies the presence of a box-shaped object in a user-defined zone (typically the front porch) and alerts on delivery and, more importantly, on removal — the "package stolen" event that is the primary use case. Animal detection is the least reliable category because animal shapes, sizes, and movement patterns vary enormously. A deer and a large raccoon both trigger "animal" classification, but the user likely wants to know about the raccoon investigating the trash cans and not the deer crossing the lawn. On-device AI that allows per-category notification toggling — alert on person and vehicle, ignore animal — is the practical interface for managing notification relevance.
