Abstract
The invention relates to a visual domestic safeguard system and the method for real-time monitoring and transmission. The object of the invention is that the said system is a host-slave system interconnected in wireless communication mode, which performs real-time detection on mobile objects and records them automatically. The visual domestic safeguard system includes a host M and several slaves Z, slave Z is mainly used to obtain video signals while the principal function of host M is to transmit signals to a server through communication networks. In the slave, digital video signals are processed with static/mobile image coding algorithm, encryption algorithm and video mobile object detection algorithm, and later transferred to host M after image compression; the received compressed video and audio signals are displayed directly or stored after decryptions decompression and video coding process, or sent to the server of the domestic safeguard system, and later transmitted to MMS mobile phones e-mailbox or hand-held devices. The invention could performs real-time image monitoring and transmission on several sites.
