Bandwidth measures how much data a network can transmit per second, typically in megabits (Mbps) or gigabits (Gbps). A higher bandwidth allows more data to move through the system quickly and efficiently.
In video surveillance, bandwidth determines how smoothly video streams run. High-resolution cameras or multiple streams require more capacity. If the available bandwidth is too low, users may experience lag, image loss, or delays.
To avoid these issues, system designers calculate the required bandwidth based on the number of cameras and video quality. They often apply compression technologies like H.265 to reduce data use while maintaining clarity.
As a result, proper bandwidth planning ensures consistent video quality and stable performance, especially in larger or network-heavy environments.
