1. The Limits of Passive CCTV Monitoring Walls
Most manufacturing plants, warehouses, hospitals, and commercial campuses already have dozens of IP cameras installed across loading bays, shop floors, and perimeters. Yet in nearly every facility, those cameras function only as passive recording devices—reviewed hours or days after an incident has already occurred because no human operator can continuously watch 32 or 64 video feeds at once.
At the same time, industrial and institutional operators are rightly reluctant to stream live internal camera feeds to external cloud servers—both because of uplink bandwidth constraints and because facility video is sensitive operational data. We built Drisva, Astrake’s dedicated industrial surveillance and anomaly detection system, to turn existing camera networks into local, proactive alerting systems.
2. Local RTSP/ONVIF Edge Inference Pipeline
Drisva connects directly to your existing NVR or IP cameras over the local facility LAN using standard RTSP and ONVIF streams—requiring no proprietary camera replacements:
- Hardware-Decoded Frame Sampling: A local Drisva edge inference node ingests multi-camera streams on-site, decoding frames in hardware and running computer-vision detection pipelines tailored to each camera’s zone and schedule.
- Zone & Schedule Rules: Each camera view can be configured with polygonal regions of interest (such as high-voltage switchgear zones, forklift aisles, or after-hours loading docks) and shift-based active rules.
- Temporal Debouncing: Rather than triggering noisy alerts on a single motion frame, Drisva verifies persistence across consecutive frames before logging an event and notifying supervisors.
3. Industrial Safety, Perimeter & Process Anomaly Detection
Drisva focuses on practical visual scenarios across industrial and commercial environments:
| Detection Category | Monitored Conditions | Supervisor Alert Output |
|---|---|---|
| Shop-Floor Safety & PPE | Hard-hat, high-visibility vest, and restricted machinery-zone entry checks | Timestamped keyframe clip, camera zone tag, and local console notification |
| Perimeter & After-Hours Security | Person or vehicle entry into gated yards, warehouses, or restricted corridors outside shift hours | Immediate alert to security desk with option to trigger zone audio warnings via Arenea |
| Process & Facility Anomalies | Conveyor blockages, aisle obstructions, or early visual smoke/spill indicators | Exception log routed to shift supervisors for rapid human verification |
4. Local Video Custody, DPDP Readiness & Human-in-the-Loop Review
Because Drisva processes video streams on on-premise edge appliances inside your facility network, raw camera footage never needs to leave your premises. Event logs are stored with configurable retention schedules and role-based access in technical alignment with India DPDP Act 2023 privacy principles, keeping every automated alert subject to human supervisor verification.
