Your selection of networking hardware, including hubs, switches and routers is also important when installing an IP security solution. These devices are all used to connect computers together on a network, but each device has different capabilities.
A hub is a device with multiple ports which has several cameras or computers connected to it. People often get hubs and switches confused. Hubs are the original switch, so to speak. There are some limitations with hubs. They have no real built-in intelligence for moving data between two devices more efficiently. Hubs also share total network bandwidth, so if you have a 100 megabit hub, and you have 8 items plugged into that hub, they have a maximum bandwidth of 100 megabits that they can share between them.
Switches generally have some intelligence built into them. We call them smart switches. It really increases efficiency of data transmissions. What’s nice about a switch, and what separates it from a hub is you have a maximum bandwidth per channel, so if you have a gigabit switch, you have a gigabit per channel that you can push data through. This makes a switch a lot better than a hub.
Hubs and switches are fairly similar in price, but since switches allow for greater bandwidth per channel and more efficient data transmission, a smart switch can be a better choice than a hub.
A router is a much more intelligent device than a network hub or switch. Network routers serve as an intermediate destination for network traffic to ‘route’ data. The devices are designed to join multiple LANs and allow you to speak to different networks within a building, or even around the world.
