Abstract The wavelet transform is ideal for image coding due to its capability for multi-resolution representation. This paper presents a remote surveillance system based on the wavelet image coding. The system contains two subsystems, the local monitor and the remote control. The local monitor consists of the image capture module, the wavelet coding module which has two blocks of 2-D wavelet transform and the zerotree coding, and the transmit module. The hardware structure of each module is designed, and the Verilog HDL modules of the local monitor are programmed and simulated. The hardware is then synthesized to FPGA. The receiver program for the remote control is designed, and the remote surveillance system is implemented successfully.
