How to Use a PoE Injector to Install an IP Camera?

Are you looking for a solution to easily power your IP cameras? It’s no doubt to use a PoE injector or Gigabit PoE switch to complete the installation. Once your system is established, you can view your home circumstance from your computer or smartphone from anywhere. Here focus on how to use a PoE injector to install an IP camera.

What Does a PoE Injector Do?

Power over Ethernet is commonly regarded as PoE for short. It’s a technology that can transfer both power and data over twisted pair Ethernet cables such as Cat5e, Cat6, etc. A Poe injector is a device that is commonly known as the “midspan”. It supplies power to a camera by delivering power into the Ethernet cable. Usually, a power over Ethernet injector converts the alternating current into direct current so it can be the power supplier for low voltage IP camera.

What Does an IP Camera Do?

Unlike the traditional cameras, IP cameras can send and receive data over a LAN or the Internet. It’s a separated unit with its own IP address that needs nothing but a network connection like WiFi or PoE injector switch. IP cameras capture images just like a digital camera, and compress the files for transmission over the network. So these images can be viewed anywhere in the world. Also, this camera can be controlled remotely.

TL-SG1008PE VS S1130-8T2F 8 Port PoE Switch

Both the two switches are 8-port poe switches. They have the port priority function which will help protect the system if the system power becomes overloaded. There are some differences between them, as one is managed switch and the other is unmanaged .

The key difference between a managed and unmanaged switch is the capability to configure the switch and to prioritize LAN traffic to ensure that the most important information gets through.

Managed switches present you more management over your LAN traffic and offer advanced features to control that traffic.

An unmanaged switch simply allows Ethernet devices to “talk to” one another, such as a PC or network printer, and those are typically what we call “plug and play.” They are shipped with a fixed configuration and do not allow any changes to this configuration.

Managed switches contain all the features of an unmanaged switch and provide the ability to configure, manage, and monitor your LAN. And this gives you greater control over how data travels over the network and who has access to it.

Conclusion

When it comes to long cable runs and cameras installed far away from the data source, nothing is more disappointing than losing the signal transmission. FS.COM power-over-Ethernet switches are designed to make installations simple, powerful, and effective. Come and contact us.

Comparison of Four 48 Port PoE Switch Price and Function

The four 48 port PoE switches that we’re going to discuss are UniFi US-48-500W, TP-Link T1600G-52PS, D-Link DGS-1210-52MP/ME and FS S1600-48T4S. They are inexpensive compared with most enterprise class 48 port PoE switches. Let’s have a look at these switches.

Difference Between the Four 48 Port PoE Switches

The table below gives some basic parameters of these four switches, including the port type, supported data rate, the maximum PoE power consumption, switching capacity and forwarding rate.

Switch Model UniFi US-48-500W TP-Link T1600G-52PS D-Link DGS-1210-52MP/ME FS S1600-48T4S
10/100/1000Mbps RJ45 Ports 48 48 48 48
Gigabit SFP Ports 2 4 4 0

Forwarding Rate 104.16 Mpps 77.4 Mpps 77.4 Mpps 130.94 Mpps
Price US$760.00 to US$1,230.90 US$481.99 to US$725.99 US$988.06 to US$1,028.01 US$689.00

The UniFi US-48-500W is a 48-port Layer 2 access switch. In addition to 48 Gigabit RJ45 ports, it has 2 fibre ports of Gigabit SFP and 2 fibre ports of 10G SFP+. It has a non-blocking throughout of 70 Gbps, which is sufficient for typical home use and most small business use. But compared with the other three 48-port PoE switches, it lacks some Layer 3 features. The other three are Layer 2+ switches that support static routing and access resolution protocol (ARP) inspecting, which are simple but efficient approaches in segmenting and securing the network.

Outwardly, the TP-Link T1600G-52PS and D-Link DGS-1210-52MP/ME are similar in many aspects. They both have 4 Gigabit SFP ports and their switch fabric capacity and forwarding rate are identical. However, the 48 RJ45 ports of T1600G-52PS are all IEEE 802.3at/af-compliant PoE+ ports, while the 48 RJ45 ports of DGS-1210-52MP/ME are not. Only ports 1-8 are PoE+ and the ports 9-48 are PoE. The price of T1600G-52PS is much lower than DGS-1210-52PS but the former one is released in 2015 while the latter one is 2017’s new model. Both T1600G-52PS and DGS-121052MP/ME has no 10G ability.

Obviously, the switching capacity (or backplane bandwidth) and forwarding rate of the FS S1600-48T4S are the highest among these four switches. It has four 10G uplink ports, which allows large traffic from the access switch to the core switch and ensures high speed and precise transmission and recording without delay. Meanwhile, it supports the largest power to the device, which is suitable for connecting more PoE network devices. This 48 port PoE switch price is lower than two of the other switches.

Common Benefits and Features of the Four 48-Port PoE Switches

These four 48 port PoE switch price are much lower than that of high-end PoE switches. They are all managed PoE switches equipped with 48 10/100/1000Mbps Rj45 ports of auto-sensing IEEE 802.3af (PoE), which provides a maximum per PoE port output power to each device of 15.4 W. They also support IEEE 802.3at (PoE+), which enhanced the max. per port power consumption to 30 W. All of them have been equipped with fibre uplink ports.

Another common feature is that these four 48 port PoE switches all support easy management. And the managing function is not limited to only one type. They all have an RJ45 console port or a serial port for managing through web-based graphical user interface (GUI, IPv4/IPv6) or command line interface (CLI).

Summary

This post has compared the 48 port PoE switch price and function. They are generally inexpensive and suitable for both home use and business use. The managing functions are simplified compared with high-end switches, in order to help better management of the network. If you want 10G uplink, UniFi US-48-500W or FS S1600-48T4S are recommended. Before purchasing a 48 port PoE switch, be sure to check the power requirement for your total PoE devices, the standard it complies to and the overall PoE budget of your installation.

Selection Guide on PoE Switch

Currently IP cameras are widely used for video surveillance due to the high requirements for security. Typically, the IP cameras are with PoE functions, then PoE switch is needed for the connection. But some users feel confused about the PoE switch and don’t know how to choose a suitable PoE switch. This article is going to introduce you some guides on PoE switch selection.

What Is PoE and PoE Switch?

PoE is short for power over Ethernet. With PoE technology, data and power can be transmitted over a single Cat5e cable. A PoE switch is a device that contains multiple Ethernet ports to provide power and network communications to IP cameras. PoE switch is an economical and reliable solution for small business networks to deploy wireless access points and IP surveillance cameras.

Considerations for PoE Switch Selection
Numbers of Ports

The most important is to check whether the numbers of ports on PoE switch are enough to connect all your devices. Fiberstore offers PoE switches including 8 ports, 24 ports, and 48 ports. PoE ports are flexible to connect with Cat5e cable without additional settings. All of our PoE switches have 2 Gigabit uplink SFP ports or 4 SFP+ ports. Uplink ports allow long distance data transmission between switches. With these ports, you can easily expand your networks. (Check news about PoE switch from FS.COM: Build and Expand Your Network with FS.COM New Introduced PoE Switches) So if you need to link multiple switches, you need to select switches with enough Gigabit ports.

Power Supplies for Powered Device

PoE switch applies two standards: IEEE802.3af and 802.3at. Each one can offer power for IP cameras. Due to the different standards, the output power of PoE switch is also different. IEEE802.3af can provide 15.4watts DC power on each port. As some power dissipates in the cable, only 12.95watts power at most can be supplied to powered devices. This standard is enough to power VoIP phones, wireless access points and some cameras over standard Ethernet cabling. While, IEEE802.3at is updated PoE standard known as PoE+. It can provide up to 25.5watts power available for powered device which is nearly twice as many as that 802.3af supplies. The updated standard can support more devices with high-power functionality such as door controllers, cameras with zoom capacity, or wireless access points supporting 802.11n.

Total Power

PoE switch has a total power. As described before, under IEEE802.3af standard, each port on the PoE switch can get 15.4watts power. Thus, the total power of a 24-port switch must reach 370watts so that it can make sure each port get sufficient power. And make sure there is additional power beyond that required for PoE for its switching functions. As to the IEE802.3at standard, each port supports 30watts. Under this condition, the PoE switch with total power of 370watts can only provide power supply to 12 ports.

Cable Requirements

The DC power of IEEE 802.3af standard is 15.4watts. It can support 10BASE-T and 100BASE-T. Two of four twisted pairs of Cat3 cable or higher can support the power and data transmission. The PoE+ standard delivers power up to 30watts and supports 1000BASE-T. Cat5e or Cat6 cable is able to support the power transmission. Connecting PoE switch to the router or cameras with Cat5e or Cat6 cable, the maximum transmission length is up to 100 meters.

When buying Ethernet cables, find a reliable vendor who provides standard network cable meeting the strict requirement. PoE power supply must use oxygen-free copper material—standard network cable. Non-standard cable utilizes other materials such as copper clad steel, copper clad aluminum, copper coated iron, etc. These cables are not suitable for PoE power supply because of the big resistance.

Conclusion

PoE switch is a cost-effective solution to increase the reliability and security of networks by providing centralized backup power to all connected IP surveillance devices.
