Why Use 8 Port PoE Switch for IP Surveillance?

Usually, 8 port PoE switch is used for supply power to powered devices (PD) for placing flexibility, including IP phones, IP phones and wireless access points (WAP). Some vendors like FS provide 8 port PoE switch with high resistance to electromagnetic interference and severe environment adaptability. This guarantee the smooth operation of weather-proof IP cameras and the stability of the whole IP surveillance system. Moreover, with all IP surveillance components centralized together with PoE switch, it is more convenient for management and control.

What Are the Considerations for Choosing 8 Port PoE Switch?

For an IP surveillance system with very few IP cameras, one can simply add a PoE injector (midspan) between the non-PoE Ethernet switch and IP cameras. This is a cost-effective solution for elementary IP surveillance system because an 8 port PoE switch is usually more expensive than a PoE injector. However, what about more than 4 IP connections are required? In this case, PoE switch 8 port is absolutely a better way to go. Here are some considerations one should refer to while selecting a proper 8 port PoE switch for IP surveillance.

·The Power Consumption of IP Camera

Knowing the power consumption of each IP camera helps to choose an 8 port PoE switch with corresponding per port power consumption and the total power budget. The power consumption of PoE IP cameras can reach up to 20W (PTZ IP cameras RLC-423), and be as low as 3 or 4W. Just remember that your 8 port PoE switch should be able to provide power for each IP camera and won’t exceed its total power budget.

·Max. Power Consumption of 8 Port PoE Switch

There are two PoE standards: IEEE802.3af and IEEE802.3at. IEEE802.3af PoE standard can deliver 15.4W maximum power on each port of the switch, and 12.95W power available at PDs. IEEE802.3at is a PoE+ standard with 30W per port and 25.5W available for transmission. Each PoE switch has power consumption specifications for per port and as a whole. For example, FS S1130-8T2F 8 port PoE switch complies with both IEEE802.3af and IEEE802.3at. Per port maximum power consumption is 30W and total budget of the PoE switch is 130W. For higher power budget, FS S1250-8T2F 8 port PoE switch can reach up to 250W. Make sure the maximum power supply of the whole switch is more than your IP cameras’ budget, or some of your IP cameras may won’t be provided with enough power. This is also the cause for poor performance and video loss.

·Managed or Unmanaged

Unmanaged 8 port PoE switch is a “dumb” plug-and-play one with fixed configuration, which runs in the most basic form with no management functionality. Managed one is an advanced version with superior functionality, configuration customization and remote security control. For heavy-workload networks with management requirement, managed 8 port PoE switch is obviously a future-proof way to go. It is noted that smart partly-managed PoE switch is a choice for functional and cost-efficient concerns. But for IP surveillance, choosing managed 8 port PoE switch is and will continue to be a future-proof solution.

There are other factors one may concern about, such as 1U form factor for space budget and stackable one for network expansion. Customized demand may be required for some special occasions. For instance, a fanless design is important for silent operation in libraries, classrooms and laboratories. FS S1130-8T2F 8 port PoE switch can meet the need. The best way is to list all those points you care about, then check each one for the targeted PoE switch.

How to Install 8 Port PoE Switch in IP Surveillance System?

An IP surveillance system comprises PoE switch, IP cameras, NVR and Ethernet cabling. To illustrate how to use PoE switch for IP surveillance, we’ll take FS S1130-8T2F 8 port PoE switch as example. This PoE+ switch has 8 x 10/100/1000Base-T RJ45 Ethernet ports and 2 x gigabit SFP ports, with IEEE 802.3af/at compatible, which means it supports 30W maximum power consumption.

To set up an 8 port PoE switch for IP surveillance, you can refer to the following tips. First connect all IP cameras and NVRs with RJ45 ports on PoE switch. Then connect LAN/WAN with SFP ports. It is noted that for non-PoE cameras, a splitter is required as a medium to connect PoE switch with IP camera. The following picture shows the detail information for installation.

Conclusion

PoE switch provides placement flexibility, space and cost saving, and management convenience to IP surveillance system. For buying 8 port PoE switch, one should concern about power consumption of IP cameras and PoE switch, managed one for superior functionality and other customized requirements. Generally an 8 port PoE switch can satisfy a small sized IP surveillance system. For medium and bigger sized systems, FS also provides managed PoE switch with 24 and 48 port.

How to Add PoE to Your Network?

In data centers, there are a lot of electrical devices and each one requires a power supply cable and at least one connection wire for transmission. It’s a disaster to see all those wires scattering all over the floor and tangling together. To introduce Power over Ethernet technology, we can cut down the number of wire drops and simplify the management control. So what’s the practical methods for adding PoE to your network? Read the following passage, to learn about the two solutions: adopting PoE switch or PoE injector.

Overview of PoE Implement Method

PoE requires PoE-enabled networking devices for power supply on the Ethernet cable. To realize this technology, there are two types of power sourcing equipment (PSE) for adopting: endspan (IEEE 802.3af refers to it as “endpoint”) and midspan. Endspan is an Ethernet switch that has built-in PoE data transmission circuitry. A midspan is an intermediary device between a non-PoE switch and powered devices (PD). Thereinto PoE injector is a frequently used available external midspan device.

Adding PoE by PoE Switch (Endspan)

When you need to set up a new Ethernet network with power over Ethernet technology or you want to upgrade system and replace older non- PoE switches, employing endspan is a good choice. How to add PoE to your network by PoE switch? Just connect it to other network devices, and the switch itself will figure whether they are PoE supportable devices and control power automatically. There are various types of PoE switch available, ranging from “dumb” unmanaged one, smart partly managed one and fully managed one with advanced management. It is also various from port quantity, such as 8, 16, 24 and 48 port.

It is noted that the PoE+ switch is a PoE plus switch for providing up to 30W power consumption. For example, FS S1130-8T2F 8 port PoE switch is a managed PoE+ switch with 2 SFP port, IEEE 802.3at complied and IEEE 802.3af backward compatible. It has maximum power supply of 130W and switching capacity of 20Gbps. FS S1130-8T2F supports various PoE devices and is best fit for network equipment such as wireless APs, IP phones and weather-proof IP cameras.

Adding PoE by PoE Injector (Midspan)

If you don’t want to discard your already used network switch and only PoE capability is needed to be added, you can simply adopt midspans. PoE injector is a device that can add electrical power while receiving signal from one end of the cable, and then deliver both the data signal and the power via the other end of the cable. Instead of PoE switch, midspan can also be used as an economical and functional solution where only a few PoE ports are in demand. How to add PoE to your existing LAN by PoE injector? First, power on PoE injector and non-PoE Ethernet switch respectively, next connect them via an Ethernet cable. Then connect PDs such as IP phones with PoE injector and finally the system can run as a whole.

In the case of older end devices are not PoE-ready, a splitter can be helpful for adding PoE to your network. To apply a splitter onto the end of the Ethernet cable will enable signal and power to be split into two different lines.

PoE switch vs PoE injector installation

This figure shows the installation of PoE switch vs PoE injector for adding PoE to network.

PoE Switch or PoE Injector: Which to Employ?

After diving into each respectively, we made a comparison of PoE switch vs PoE injector for concerning about adding PoE to network.

PoE Switch PoE Injector
Price Higher Cost Economical
Management and Control Easy for management (power and transmission) Requiring separate two wires for powering on switch and PoE injector
Implement Method Upgrade to PoE network by replacing the old Ethernet switch with PoE switch Install PoE injector to add PoE capability to the existing non-PoE switch
Emergency Reaction Potential chance of the whole system’s outage Only one device be affected

For most concerns about cost-efficiency and PoE capability required, you can go for PoE injector. However, for upgrading system and future-proof superior functionality concern, PoE switch is obviously a better choice.

Conclusion

Both PoE switch and PoE injector are power sourcing equipment for adding PoE to a network. PoE switch is an endspan, naturally fitting for new set-up or upgrade-needed network. PoE injector is a midspan, better fitting for existing non-PoE network without switch replacement requirement. For PoE switch purchase, FS.COM is a reliable vendor providing a wide rage of types for different demands. Any other information to know, just visit our official website and blog.

Understanding SFP Ports on SFP Switch

Catching a glance of the modern network devices, one will see different ports are built in for different connection. For instance, we got USB interfaces in cellphones and RJ45 ports in copper switch. But how about SFP port? SFP port is built-in interface in various devices including gigabit switch, SFP switch, network interface card (NIC). This article will focus on the understanding of SFP ports on SFP switch.

What Are SFP Ports on SFP Switch?

SFP port (mini-GBIC port), a small form-factor hot pluggable interface, is designed for high speed and density SFP connection. It is typically built in 10Gb switch with SFP+ uplinks. Different from RJ45 ports for copper connection only, SFP ports on SFP switch support both copper and optical links. When SFP ports on SFP switches are inserted into SFP modules with electrical ports, Ethernet copper cables (Cat5e/Cat6/Cat7) are needed for data transmission. When SFP ports are plugged by SFP optical modules with optical ports, fiber patch cables are required for data transmission. Counting to this feature, SFP ports empower SFP switches the switching function to connect various Ethernet and fiber cables through the network. For the fiber one, single mode fiber (SMF) and multimode fiber (MMF), 1GE and 10 GE speed are all compatible. Moreover, it contributes to the adaptability of either short distance transmission by deploying RJ45 SFP or long distance transmission by fiber SFP.

FS SFP switch

Figure 1: This is a demonstration of SFP ports on FS SFP switch plugged by fiber SFP modules, then connect single mode fibers for data transmission.

SFP Ports Advantages on SFP Switch

·Small Size and Hot-pluggable Feature

Compared with early GBIC module port, SFP port for SFP module has much lower volume ratio. This small-sized optimization enables 2 times the density for SFP ports configuration on the same patch panel. Thus also expands the whole data capacity. Besides, SFP port is an I/O device, which is hot-swappable. Moreover, SFP ports on SFP switches can be exchanged with different port types, such as 1000Base-SX, 1000Base-LX/LH, 1000Base-ZX and 1000BX10-DU.

·High Reliability and Security

Fiber SFP plugged into SFP port on SFP switch usually connects with a fiber cable, which delivers data in light rather than electrical signal. First, for reliability concern, it largely diminished data loss and electromagnetic interference. Second, for security concern, fiber jumpers are less likely to catch on a fire than copper cables in severe environment. Sensitive data information is also more difficult to be illegally filched.

·10 GE SFP+ Uplink for Higher Network Capacity

Gigabit switch often has built-in SFP ports and SFP+ ports. They can support the load blancing of redundant links. Even though currently you only need 1GE network, for the concern of later system upgrade and future-proof technology, 10GE SFP+ ports are necessary for SFP switch.

How to Use SFP Ports on a SFP switch?

To illustrate the usage of SFP ports on a SFP switch, taking FS S5800-48F4S 10gb switch as an example. FS S5800-48F4S 48 port gigabit SFP switch comes with 48 x 1GbE SFP ports and 4 x 10GbE SFP+ ports. It has a 176Gbps switching capacity with low latency in a cmpact of 1U form factor.

Patch Panel vs Switch: What’s the Difference?

In network setups we see everything is plugged into a switch, but before that fiber cables are also connected to another supply – patch panel. Thus one question is often confusing: patch panel vs switch: What’s the difference and what’s the significant function of them respectively?

What Is Patch Panel?

Patch panel (fiber optic patch panel, fiber optic enclosure) is a terminate unit of network ports centralized together. It is a cable management solution component used to organize fiber cables and keep everything neat for a clean wiring closet. In data centers, a mass of cable wires scattering all over and mixed together can be bothersome, in this case a patch panel is indispensable and rather helpful. It not only offers ease of management, but also protect the terminations from being knocked. Besides the fiber optic patch panel, other cable management accessories including cable ties and cable labels are also used to keep cables tidy and easy for identification.

Figure 1: This photo shows the application of patch panel by FS.COM for cable management in a data center.

What Is Switch?

Switch, commonly known as network switch, is an appliance in a data center that connects all devices (such as PCs and servers) as a whole to achieve intercommunication and data sharing between different network devices. It channels the incoming data from multiple input ports to the specific output port so as to deliver the data toward its destination. In Ethernet LAN or WAN, modern network switch usually determines which output port to use by network address.

Figure 2: This photo shows the application of network switch by FS.COM in a data center.

Patch Panel vs Switch: What’s the Difference?

Table below shows the main difference of patch panel vs switch.

Name Patch Panel Switch
Price Cheap Expensive
Role playing Cable management tool:
Centralizing cable wires together; protecting fiber cables from damage.
Functional performance: connecting all devices together to receive and transmit exact messages to the target device end.
Form feature  fiber optic patch panel  network switch
·Role in Date Center

Comparing patch panel vs switch, we can make the following conclusion. Patch panel is nothing but an essential cable management tool, which exerts no functional influence to the performance of data transmission. However, a switch is an irreplaceable functional supply in network setups.

Why Patch Panel Is Commonly Set Up in Network Installation?

As mentioned above, patch panel has no effect on the data transmission process. Can it be omitted in fiber optic cabling? Or can wires just directly plugged to a switch? The answer is yes when you just deal with several fiber cables. However, Ethernet patch panel is a must in data centers where there are a large number of Ethernet drops. No doubt you don’t want to see all the things tangled together. A patch panel in place provide ease management of classification, maintenance, repair, installation and upgrades.

Conclusion

This article gave an brief introduction to patch panel and switch respectively and then discussed the differences between them. Patch panel vs switch : what’s the difference, and why is a patch panel commonly set up in network installation whereas a switch is already used? Can you answer these questions now? Simply put, patch panel is an essential cable management tool whereas network switch is a significant functional supply in data center. Both of them play important role in their respective positions.
