If you use a 24 ports switch with 100 Mbps transmission per port, that means you will use only 2.5% of the capacity of each port per video stream.<\/p>\n<p><span><\/span><span>Gigabit ports:<\/span> In most cases the switches need to have ports with only 100 Mbps to connect the cameras, however, for the connection between two switches or with the server you can use the Gigabit port that allows to sum up the traffic of the 24 ports in a single port.<\/p>\n<p><span><\/span><span><\/span><span>Bandwidth: <\/span>Usually<span><\/span>&nbsp;there are switches with&nbsp;24 100 Mbps ports and 4 1000 Mbps ports with total bandwidth of <span>12.8 Gbps<\/span>, this means that we could use the maximum capacity of all ports without problems, but we already know that we don&#8217;t need that much&nbsp;for cameras.<\/p>\n<p><span><\/span><span><\/span><span><\/span><span>Fiber Optic:<\/span> Some switch models have fiber optic module inputs to allow connections over long distances.<\/p>\n<p><span><\/span><span><\/span><span><\/span><span><\/span><span>Redundancy<\/span>: If you need to use redundancy in your project,&nbsp;the switch has the ability to work with standard STP and RTSP protocols that guarantee high speed redundancy.<\/p>\n<p><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span>Virtual LAN (VLAN):<\/span> In projects that need to isolate broadcast traffic and implement security, VLANs are very useful, most switches allow you to manage a minimum of 256 VLANs with the 802.1Q protocoal standard.<\/p>\n<p><strong>==&gt;<\/strong> I recommend you to read the article <a href=\"https:\/\/learncctv.com\/the-use-of-vlans-in-cctv\/\" target=\"_blank\" style=\"outline: none;\" rel=\"noopener noreferrer\">How to setup VLANs for CCTV<\/a> to learn more about VLANs (it&#8217;s really important).<\/p>\n<p><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span>Multicast: <\/span>When it is necessary to work with multicast streaming the switch must allow the use of specific protocoIs such as IGMP snooping v1, v2 or v3 or IGMP querier.<\/p>\n<p><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span>COS and QoS:<\/span> In a network with different devices, sometimes it is necessary to prioritize some of them, in which case the use of COS (Cost of Service) and Quality of Service (QoS) technology must be available on the switch.<\/p>\n<p><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span><\/span><span>Security:<\/span> To implement security it is recommended to have some features such as 802.1X, Radius and TACACs, so only the cameras and monitoring\/recording servers can connect to the network.
