Mobile video surveillance with low-bandwidth low-latency video streaming
Giovanni Gualdi, Andrea Prati, Rita Cucchiara · 2007
This paper presents a system for remote live video surveil-lance. Videos are acquired from a fixed camera at 10 fps and QVGA resolution, compressed at 5 or 20 kbit/s with H.264, and streamed to a remote site, where they get processed by an automatic video surveillance system. The target surveil-lance application performs moving object segmentation and tracking. Both ends (video acquisition and processing) could be connected through a wireless network, specifically GPRS. The whole system is studied and optimized to maintain low latency. The reported experiments demonstrate that the proposed system is able to send up to four video streams over GPRS or E-GPRS network, without significantly af-fecting the performance of the automatic video surveillance system. Comparative tests have been performed with other existing streaming solutions.
