Abstract - Real-time monitoring systems, especially those based on wireless infrastructure, are often plagued by issues of packet loss, jitter, and latency due to network unreliability. This paper introduces a backward error correction (BEC) technique specifically designed to improve media quality and reliability in real-time video/audio streaming over wireless IP networks. By leveraging selective retransmission of lost Real-Time Protocol (RTP) packets through an intelligent feedback mechanism based on sequence gaps, the technique balances efficiency and recovery in low-latency environments. We explore its system architecture, implementation mechanics, and performance outcomes. The proposed method is validated against existing techniques and demonstrated to be especially suited for wire-free surveillance systems such as smart security cameras.

Key Words—Real-time monitoring, backward error correction, RTP, RTCP, packet loss recovery, wireless surveillance, sequence gap detection.
