Design of high - Reliability and HD video remote surveillance system

<p>Remote video monitoring has become increasingly important for monitoring the security of purpose locations. Most of the surveillance system needs high-definition (HD) video. Multi-channel HD video data real-time transmission and data transmission security are two of the factors restricting the development of remote monitoring system. To solve this problem, this paper presents a new high-definition video surveillance system program, high-definition camera video by video relay input to high-definition video encoder, high-definition video encoder for data compression, compressed data input HD video decoder after long-distance transmission by Gigabit Ethernet, high-definition video decoder to decode the compressed data, then the video data input DVR after decompression, the video data may be stored and can be displayed in real time. A balanced algorithm is used to adapt transmission bandwidth and a iterative algorithm is used to smooth out random packets loss rate. After testing, the system can transmits five hundred compressed video data and have excellent expansibility; data transmission is very secure because of independent Ethernet and encryption algorithm. &copy; 2018 SPIE.
