The aggregation layer and the core layer are calculated according to how many images the switch aggregates. In terms of network topology, a local area network (LAN) is usually a two- to three-layer structure. The end that connects to the camera is the access layer and a 100M switch is sufficient unless you connect many cameras to one switch. These are all explained by taking the mainstream H.264 camera as an example, and the H.265 can be halved. With a Gigabit switch, you can connect 75 sets (75×8=600M) With a 100M switch, you can connect 7 units (7×8=56M) The bitstream of a 1080P IP camera usually is 8M. With a Gigabit switch, you can connect 150 sets(150×4=600M) If a 100M switch is used, then 15 cameras can be connected (15×4=60M) The bitstream per 960p camera usually is 4M. Therefore, the available bandwidth of their ports is roughly 60Mbps or 600Mbps.Ĭheck the bitstream of a single camera according to the brand of your IP camera and then estimate how many cameras can be connected to a switch. ![]() Then, you should know the bandwidth capacity of the switch. Commonly used switches are 100M switches and Gigabit switches, whose actual bandwidth is generally only 60~70% of the theoretical value. Camera bitstreamīefore choosing a switch, the first thing you should do is to figure out how much bandwidth each image occupies. Choose according to the bitstream and quantity of the camera 1. How many IP cameras can an Ethernet switch connect to? How many Gigabit switches can be connected to 2 million network cameras? Is it possible to use a 24-port 100M switch for 24 IP cameras? Let's make an analysis on these problems! Part I.
