Network bandwidth considerations when using IP cameras.
It is important to understand the amount of network traffic on a system and the impact of exceeding hardware capacity. To get an idea of the amount of traffic currently on the network connection, the Windows Resource Monitor can be used.
A camera feed open in a web browser and open in a video recording program will both use network resources. The amount of resources used depends on how the video feed is accessed and the amount of compression.
The following examples highlight the impact of viewing a video stream in a web browser vs. using Noldus Media Recorder. All cameras were set with a frame rate of 30fps and resolution of 1920x1080. The switch tested is a GS116PP Gigabit switch. If using a 100Mbps maximum switch, the network bandwidth will max out around 90Mbps. If the switch capacity is exceeded, the video stream will be intermittent, and the video feed may appear frozen, slow, or cut in and out.
Examples of Network Resources used with different combinations of cameras configured in Media Recorder and open in web browser.
