Typical Application Scenarios

Industrial Security Surveillance: 4K60 Ultra-HD Video and Compliant GB28181 Access

In surveillance upgrades for industrial plants, industrial parks and electric power facilities, the core requirements are seeing details clearly in the video and connecting the video stream to the upper-level platform in a compliant way. The IDM-NVD8100/4K 4K60 HD network audio and video codec captures 4K@60fps video over HDMI2.0, encodes it into an H.265 stream and transmits it to the surveillance platform over GB28181, so the platform side can bring it under centralized management without an extra transcoding gateway; H.265 Main Profile Level 5.0 encoding uses less bandwidth at the same picture quality, making it easy to add ultra-HD sites onto an existing industrial ring network. ROI and SmartP smart encoding can concentrate the bit rate on areas of interest such as people and equipment, balancing picture clarity and link margin. For industrial security projects that need product showcase, this codec can intuitively present ultra-HD picture details; in government private network optical fiber communication solutions, optical multiplexers and video optical multiplexers can serve as link supplements,while working with an experienced optical multiplexer manufacturer and brands such as Raytrans helps the overall solution land reliably.

Unattended Sites: 7×24 Operation with Direct AC220V Supply and Power <10W

For unattended pumping stations, substations, communication base stations and remote equipment rooms, power supply conditions and maintenance frequency determine equipment selection. The IDM-NVD8100/4K uses a direct AC 220V supply, with overall power consumption below 10W, an operating temperature range of 0~70°C and dimensions of 440×190×34mm, making it easy to install in a standard cabinet and suitable for deployment with long-term online operation and sparse maintenance. The device can continuously encode and upload on-site HDMI video, and supports streaming files on a FAT32-format USB drive as a live stream, so that even without a capture source it can output content such as safety prompts and inspection notes on schedule, keeping the video link of unattended sites online. In smart mining communication solutions, this kind of low-power device is equally suited to long-term operation at underground and remote sites; where a military emergency communications vehicle solution is involved, its compact dimensions and wide-temperature design also meet the deployment requirements of a vehicle-mounted cabinet.

Remote Command and Dispatch: Multi-Protocol Interconnection with SRT and ONVIF

Remote command and dispatch requires low-latency backhaul of front-end video, clear delivery of back-end instructions, and front-end devices that can be viewed on platforms from different vendors. The IDM-NVD8100/4K 4K60 HD network audio and video codec supports GB28181 transmission, ONVIF transmission and reception and SRT at the same time; it can carry out SRT protocol audio and video transmission of video from HDMI cameras or conference terminals, achieving better packet loss resistance on public network or private network links; a decoding capability of 4K60×1 means that the same device can both upload front-end video and restore the network stream sent down by the command center to an HDMI signal for on-screen display, enabling two-way video consultation and video retrieval. For command and dispatch system manufacturers, this device can be incorporated into the overall solution as a front-end encoding and decoding node; in government private network optical fiber communication solutions and military emergency communications vehicle solutions, together with optical multiplexers, video optical multiplexers and products from a reliable optical multiplexer manufacturer (such as Raytrans),a complete link from transmission to encoding and decoding can be built.
