This paper presents a smart ZigBee indoor security system based on the small-scale fading effect of RF signals. The received signal strength in a wireless network stays stable with low variances in a closed indoor environment. The movement of objects will induce a small-scale fading effect, resulting in dramatic changes of the signal strength. The main idea is to deploy a ZigBee network in the detection...
A multi-server video monitor system based on streaming media communication technology is proposed. Large-scale, long-distance monitoring requirements have been met. The video monitor software is researched, which has the function of video restoration, proprietary protocol is used to realize video transmitting smoothly. In the part of the software programming, multi-threaded mechanism and double buffering...
