PoE, Gigabit, and Network Switch what you need to know

Time and time the question of what are PoE, Gigabit, and Network Switch is commonly asked when dealing with surveillance cameras. So what are Network switches? The network switch also called switching hub, is networking hardware that connects devices on a network by using packet switching to receive and forward data to the destination device. It facilitates the sharing of resources by connecting together all the devices, including computers, printers, and servers, in a small business network. Thanks to the switch, these connected devices can share information and talk to each other, regardless of physical location.

Types of Switches

Modular switches:
Modular switches let you add expansion modules as needed, giving you flexibility as network requirements change. This type of switch provides you with the most flexibility, but at a higher cost.

Fixed-configuration switches:
Fixed-configuration switches provide a fixed number of ports and are typically not expandable, which makes them less expensive overall.

Forms of Fixed-configuration switches

  • unmanaged switches
  • smart switches
  • managed switches.

Unmanaged switches: are typically used to provide basic connectivity. They’re designed to be plug and play; no configuration is needed. Unmanaged switches are most effective when only basic switching and connectivity are required.

Smart switches: offer some management and segmentation, quality of service, and security capabilities, so they can be a cost-effective alternative to modular switches.

Managed switches: Among the fixed-configuration switches, the managed switches provide the highest levels of security. As a result, managed switches are usually deployed as access switches in very large networks or as core switches in smaller networks.

Features

In addition to evaluating switch categories, you should also consider network switch speeds, the number of ports, and power-over-Ethernet(PoE) features.

Switch speeds
Switches are available in different throughputs or speeds, the rate they transmit data in megabits per second (Mbps). For example, fixed-configuration switches can provide Fast Ethernet (10/100 Mbps), Gigabit Ethernet (10/100/1000 Mbps). The switch speed you choose depends on the type of throughput you need.

Number of ports
As is the case with switch speed, the number of ports available in a switch can vary. Fixed-configuration switches are usually available with 4,8, 16, 24, 48, or 52 ports.

Power over Ethernet (PoE) vs. non-PoE
PoE lets you power a device—such as an IP phone, surveillance camera, or wireless access point—over the cable that is used for data traffic. This allows you to place endpoints anywhere, even in those areas that are usually difficult to reach. Switches with PoE are more expensive, however. As you evaluate your options, think about the devices you would like to connect to determine whether PoE is required.
