Network bandwidth refers to the amount of data that can move through a network connection in a given period, usually measured in megabits per second (Mbps) or gigabits per second (Gbps).
In surveillance systems, higher bandwidth allows multiple video streams to transfer smoothly without delays. For example, streaming high-definition footage from several cameras requires more bandwidth than a single low-resolution feed.
If bandwidth is too low, users may experience lag, image distortion, or dropped frames. To avoid these problems, many systems use compression technologies like H.265 to reduce data usage while maintaining video quality.
Proper bandwidth planning ensures stable video transmission, especially in large or network-intensive environments. As a result, operators can monitor systems reliably in real time.
