8 Port PoE Switch Selection Guide And Tips

POE(Power over Ethernet) is ideal for using in smart applications which makes CCTV even more effective and easier to manage. The network can be monitored, controlled, and managed from a smartphone or tablet. With a POE switch such as the Netgear ProSAFE 8 port switch, remote IP surveillance cameras can be controlled and managed no matter where they are located. Facing the selection of 8 port PoE switch, most of people would occur allodoxaphobia. For fixing this hard-decision problem, this article would put emphasis on 8 port PoE switch selection guide and tips.

8 Port PoE switch Selection Guide & Tips

—Power Requirements

Review the data sheets of the camera’s you have specified on the installation to see if any have higher power requires known as PoE+. If you have 1 or more camera’s requiring PoE+ power you will need to heavily consider this when choosing your switch. (Please note PoE+ switches will happily power standard PoE devices but a standard PoE switch cannot power any PoE+ device, regardless of the amount of wattage unused by the other connected equipment). However some switches are designed to power both PoE and PoE+ devices, please check the specification sheet of that exact switch model to see if this is possible on your selection. If this is the case you will usually find a the switch will handle half the PoE+ devices it will PoE e.g. An 8 port switch can power 8 standard PoE devices or 4 PoE+ devices.

—Cable Run Length

Make sure when planning your network you do not have cable runs longer than 90 meters. This is particularly important when using PoE due to voltage drop. PoE is particularly hard to measure voltage on so if you break the 90 meter cable rule you could be in for a world of pain if devices do not operate correctly.

—8 Port Switch Price

There are many 8 port PoE switches of major brands on the market, such as Cisco, Netgear, HP, TP-Link and etc. The 8 port switch price varies in difference brands. But they all controlled in a certain range, it’s around $40~$300. For brand selection of 8 port PoE switch, that depends on your preference. You can check the price discrepancy with major brands in the following table. Notice: All the following prices except FS.COM are from Amazon.

Brand Model Price
Cisco SF302-08P 8-Port PoE Manged Switch $153.11
NETGEAR GS108PEv3 8-Port PoE Managed Switch $79.99
FS.COM S1130-8T2F 8-Port PoE managed switch $159.00
HP 2530-8-POE+ Ethernet Switch $270.00

Conclusion

This article mainly introduce FS.COM S1130-8T2F 8 port PoE switch and provide 8 port switch selection guide and tips. How to choose a reliable supplier from so many 8 port switch manufacturers? Before buying 8 port PoE switch, the quality, power requirement, price, cable run length should be considered. As one of well-known 3rd-party optics manufacturers, FS.COM is suggested to be a good choice for 8 port PoE switch.

Getting to Know PoE Network

With the rapid development of networking, a variety of technologies have been created. In 2003, PoE (power over Ethernet) network technology has been standardized. And it is now widely used for wireless LANs (local area networks), IP cameras and VoIP (voice over Internet protocol) phones. PoE allows cables to carry both electrical power and data signal to devices. Electrical current will support the operation of devices which greatly reduces the amount of wires used for network installation. Thus, the emergence of PoE network is absolutely a good news for the development of cost-efficient networking. Next, more information about PoE network will be discussed in the following paragraphs.

Operating Principle of PoE

There are three basic components in PoE system – PSE, PD and Ethernet cable. PSE (power sourcing equipment) like PoE switch is the device used for delivering power to cable. PD (powered device) is the device used for receiving power from the cable. And cable will help transmit the electrical power and data signal. The electrical current will first go into the cable at the PSE end, and then come out at the PD end. Since it is the transmission of electric signal, PoE is only available to twisted pair Ethernet cabling. Also, the current is separated from data signal so that neither of them interferes with the other.

Advantages of PoE

Using the PoE network has many advantages:

  • Flexibility
    Because devices like IP cameras and wireless access points are not permanently attached to an electrical outlet, they can be located regardless of area restriction. Reinstallation is also easy to implement.
  • Safety
    PoE network is designed to be safe enough to protect network equipment from overload, underpowering, or incorrect installation.
  • Dependability
    PoE power comes from a central and universally compatible source instead of a collection of distributed wall adapters. And an uninterruptible power supply is backing up the PoE network for a more stable operation.
  • Scalability
    Owing to the electrical power available on PoE network, the installation and distribution of network connections are more simple and effective.
Applications of PoE

VoIP phones, WLAN, RFID (radio frequency identification), security cameras or access control devices are major applications for PoE network. Using PoE network enables the VoIP to receive uninterrupted power through the network, without the need for an AC outlet for each phone. And WLAN access point can be placed in different locations such as ceilings, hallways, lobbies without electrical outlets. Likewise, PoE allows RFID readers to be strategically situated in locations that optimize effectiveness. And it is cheaper to use PoE network for security cameras or access control devices on ceilings, hallways, lobbies, or outdoor areas.

Conclusions

To sum up, the advent of PoE has greatly improved the effectiveness of network. Equipment are able to be located at any place due to the power availability. And a large number of cost will be saved by eliminating unnecessary wires. This article only gives a brief introduction to the PoE network. There still has a lot for us to explore.
