Product Overview
The Mine Image Surveillance System provides comprehensive image capture, transmission, and display capabilities for both underground and surface coal mine environments. Maintaining the original integrity and real-time nature of video information, the system supports multiple recording modes and retrieval functions, serving as the core industrial television monitoring platform for modern mining operations.
Product Description
Visual surveillance is a fundamental requirement for safe and efficient mine operations. The Mine Image Surveillance System is engineered to deliver reliable, high-quality video monitoring across the full spectrum of underground and surface mining facilities — from extraction faces and transport roadways to ventilation shafts and surface processing plants. The system preserves the original integrity and real-time characteristics of all captured video, ensuring that operators see exactly what is happening at every monitored location without degradation or delay.
The platform supports four recording modes — manual, scheduled, alarm-triggered, and motion-detection — giving operators the flexibility to configure surveillance strategies that match each zone's specific requirements. Advanced playback capabilities include time-based search, event-based search, fast forward and rewind, variable-speed playback, and frame-by-frame advancement, enabling rapid review and analysis of recorded footage. The recording equipment features full-duplex record-and-playback functionality, meaning that recording continues without frame loss even under maximum load — a critical capability for post-incident investigation.
Network connectivity is achieved through TCP/IP interfaces, supporting network-based playback and remote query capabilities. The system includes video-loss alarm functionality and alarm-linked response with a reaction time of no more than 5 seconds, ensuring that incidents are promptly detected and surfaced to operators. A two-way intercom feature with audio loudness of no less than 85 dB(A) enables real-time voice communication between the control center and field locations.
Transmission flexibility is a hallmark of the system, supporting cable, fiber optic, Ethernet, and wireless transmission methods. This multi-mode capability allows the system to be deployed across diverse underground topologies where no single transmission medium is universally practical. The system is compatible with mainstream video equipment, including intrinsically safe cameras with H.264/H.265 compression and 10/100 Mbps transmission rates, intrinsically safe PTZ dome cameras with 360° continuous rotation and dual-stream technology, and flameproof network cameras operating at 127 V AC with Webservice support and dynamic IP addressing.
