Insights on AI video analytics and smart security
Person Re-Identification
Person re-identification (Re-ID) is the computer vision task of recognizing the same individual across different cameras, camera angles, and times — based on full-body appearance rather than facial features. It enables following a subject of interest across an entire camera network without requiring full face recognition.
Hybrid Deployment
Hybrid deployment in video analytics refers to architectures that combine edge and cloud components — running some AI modules directly on cameras or local servers while sending other workloads to the cloud. It is the dominant architecture for large production deployments because neither pure edge nor pure cloud is optimal for every workload.
H.265 HEVC
H.265, also known as HEVC (High Efficiency Video Coding), is the successor to H.264. It delivers approximately the same video quality at roughly half the bandwidth — a major advantage for IP camera deployments with many streams or high resolution (4K and above).
H.264 Codec
H.264, also known as AVC (Advanced Video Coding) or MPEG-4 Part 10, is a widely deployed video compression standard that has been the default codec for IP cameras and video surveillance for over a decade. It balances compression efficiency, computational cost, and broad ecosystem support.
Fare Evasion Detection
Fare evasion detection is an AI video analytics capability that identifies when a passenger enters a paid-access zone — transit turnstile, platform gate, validation point — without paying the fare, and generates a real-time alert or evidence record for enforcement.
Dwell Time Analysis
Dwell time analysis is an AI video analytics capability that measures how long individuals remain in a defined zone — a store aisle, a service desk, a platform, an intersection — and aggregates that data into actionable insights about attention, engagement, or congestion.
Cloud Video Analytics
Cloud video analytics is the deployment model where AI analytics run on centralized cloud servers — rather than on the camera (edge) or an on-premise server — with camera streams ingested over the internet and results delivered back to operators via web or mobile clients.
Camera Frame Rate
Camera frame rate — measured in frames per second (FPS) — is the number of images a camera captures and transmits each second. It is one of the most important trade-offs in any surveillance deployment, balancing smoothness, bandwidth, storage, and analytics accuracy.
Video Intrusion Detection
Video intrusion detection is an AI video analytics capability that identifies unauthorized people or vehicles entering protected zones and triggers alerts in real time. Unlike traditional motion sensors that fire on any pixel change, video intrusion detection classifies what's moving and enforces zone-based rules.
