Resolution—an indispensable parameter in the realm of digital surveillance—holds the key to performance aspects such as clarity, storage capacity, bandwidth allocation, and pricing. Striving for an optimal resolution that enhances video playback quality without inflating costs or data storage requirements is a quest that defines our pursuit of excellence.   Within the dynamic landscape of the surveillance industry, various resolutions take center stage, including QCIF (176x144), CIF (352x288), HALF D1 (704x288), and D1 (704x576). Among these contenders, CIF resolution has carved a prominent niche, embraced by a significant majority of products. CIF's ascendancy can be attributed...

The development of network video surveillance technology has gone through four stages:(1) Close-range Monitoring:In the early stage of video surveillance, video images were transmitted from the front-end monitoring points to the monitoring center through coaxial cables and displayed on the monitoring equipment. As the number of monitoring points increased, the cost and management difficulty of video display and recording equipment also increased significantly. The introduction of video matrix technology effectively addressed these issues by allowing multiple video images to be switched, displayed, and shared. However, analog video transmission was limited and did not support multi-center and...
