Technology Overview

WebSocket technology enables persistent, bidirectional communication between Sunell IP cameras, NVRs, and web-based management platforms. By maintaining a continuous connection, WebSocket ensures low-latency data delivery for real-time video status, event notifications, and device interaction.



Core Functions

Real-Time Data Transmission

Sunell devices leverage WebSocket to push live device states, alarm events, and system messages instantly to browsers and centralized platforms without repeated polling.


Event & Alarm Synchronization

AI events, perimeter alarms, thermal warnings, and system notifications are delivered through WebSocket channels, enabling immediate response and visualization on monitoring dashboards.


Interactive Device Control

WebSocket supports responsive user interactions such as PTZ control feedback, device configuration updates, and session-based communication with Sunell cameras and recorders.



Architecture Benefits

Compared to traditional HTTP request-response models, WebSocket reduces bandwidth overhead and server load, making it suitable for large-scale CCTV deployments with frequent event updates.



Applications in CCTV Systems

WebSocket is widely used in Sunell web clients, VMS platforms, and cloud-based systems to support real-time alarm pop-ups, device health updates, live analytics results, and multi-device status synchronization.



Key Advantages

  • Persistent low-latency communication

  • Real-time event and alarm delivery

  • Reduced network and server overhead
