How to Add Camera Monitoring to a Retail SaaS Platform

Description and use

A retail SaaS platform implemented camera monitoring with store‑scoped live video, case‑scoped playback, strict ACLs, and performance rules to avoid browser freezes.

Problem

Retail SaaS platforms need camera monitoring but starting with a large mosaic of live feeds leads to performance issues and unclear access control.

Outcome

The platform now serves live and playback video per store with proper ACLs, reducing performance bottlenecks and improving user experience.

Workflow

• 1. Define store, region, and camera tables with roles and zones.
• 2. Implement assertStoreAccess to enforce store‑level ACLs.
• 3. Register zone metadata as enums and optional register_id per case.
• 4. Add store page with a single live player per camera, destroying it on cleanup.
• 5. Create playback endpoint that validates case ownership and camera capabilities.
• 6. Enforce performance rules: limit concurrent live sessions, pause on visibilitychange, serve HD only to focused player.
• 7. Write access‑control tests for regional users, store managers, and associate roles.
• 8. Use ShrinkCase payload for playback requests, rejecting invalid bodies.

Evidence

Performance problems in retail dashboards are almost always “too many live players” plus “forgot to destroy the last one.”
