Solution for NVR equipment video source to monitoring center

With the promotion of networking and high-definition trends, NVR network video recorders are widely used in the security product market. NVR is not only a network video recorder, but also has storage and switching functions. NVR recorders are equivalent to the whole picture Come. However, the NVR does not have the transmission function. If the video source of multiple NVR devices is to be monitored and managed in a unified manner, the video transmission equipment needs to be used in conjunction.
Project requirements: For example, NVR network video recorders are used in tourist attractions parks. How to transfer Beijing NVR equipment video, Shanghai NVR equipment video, and Shandong NVR equipment video to the central point of Hunan for unified management and monitoring. In other words, how to manage and monitor the video sources of NVR equipment in different regions.
Solution:
As long as the NVR video source signal is equipped with E-series/G-series video encoders of Qianshi Electronics for input, transmission and storage through the network, and then with Qianshi D300-4K HD decoder at the central point for output to the monitoring center.

G-series video encoders can encode and compress SDI or HDMI video sources into network streams. Wired/WIFI/expanded 4G network to realize long-distance high-definition video transmission/live broadcast on Internet WAN or LAN. It adopts H.264 encoding technology and supports dual-stream output. The main stream supports 1080p60Hz video encoding, and the sub-stream supports 720p 60Hz video encoding. The output resolution can be customized; in
addition to supporting general protocols such as RTSP/RTMP, It also supports other customizable protocols such as the security Onvif protocol. It comes with a MicroSD/TF card slot, supports local recording, and supports NAS network storage; so there is no problem connecting the video encoder to the NAS device. Moreover, the video encoding delay is small (≤67ms) and does not freeze; the video encoder can also provide SDK secondary development, which can be combined with the encoder for software development.
D300 4K HD video decoder is a professional hardware decoding device, without relying on a computer, it can decode multiple network video streams (such as IP-Camera, RTSP/RTMP/RTP-based unicast or multicast media streams, etc.) , Output SDI signal and HDMI signal video, support 4k resolution, and support multi-channel video stream split screen on the wall and dynamic switching.
The H.265 decoding technology adopted by the 4K HD decoder supports 4 channels of 4k video, or 16 channels of 1080p30 HD video decoding and output at the same time; supports 16 channels of video stream dynamic switching output, seamless switching without stuttering; 16 channels of video custom 1 /2/4/6/8/9/16 split display; decoding delay <200ms.
