Title: Optimizing Real-Time Surveillance: A Technical Analysis of ViewerFrame Mode Refresh Mechanisms
Abstract In the domain of digital video surveillance and closed-circuit television (CCTV) systems, the efficiency of the client-side rendering loop is paramount to operational integrity. This paper explores the "ViewerFrame Mode," a conceptual framework for video display, and analyzes the best practices for its refresh mechanisms. By distinguishing between passive (timer-based) and active (event-driven) refresh models, we identify the superior methodologies for ensuring low latency, high frame rate consistency, and optimal resource utilization. The analysis concludes that a Double-Buffered, Event-Driven Refresh Model utilizing Vertical Synchronization (V-Sync) represents the "Best" standard for modern surveillance applications. viewerframe mode refresh best
Best Practices for ViewerFrame Refresh
✅ 7. Adaptive Refresh Based on Visibility
Use the Page Visibility API to pause refreshes when the frame is in a background tab: Best Practices for ViewerFrame Refresh ✅ 7
document.addEventListener('visibilitychange', () =>
if (document.hidden) pauseRefreshes();
else resumeRefreshes();
);
✅ 4. Provide Visual Feedback
- Show a subtle loading indicator inside the frame (not blocking entire UI).
- Use skeleton screens instead of spinners for partial refresh.
- Avoid full-page spinners for frame updates.
