Why and How to Use PoE Switch for IP Camera Systems

Posted on By FS.COM

A PoE switch provides power supply and data connection to PoE IP camera systems via network cables like Cat5, Cat5e and Cat6. In today’s business and daily life, whatever the industry or location, using PoE switch for IP camera to ensure the safety of people and business is a very common and even popular behavior. Usually, for different IP camera systems, PoE switches with different ports are deployed. This article will explore these situations in details.

Why Use PoE Switch for IP Camera Systems?

When it comes to adopting PoE technology, some users may think it’s unnecessary to buy a PoE switch with a relatively high price. A PoE injector also can power IP cameras and save more space. However, what if there are many devices, say ten IP cameras, needing to be connected together? Under this condition, a PoE switch is the optimal choice. Besides, PoE switches also provide the following benefits for PoE IP camera systems.

PoE Switch for IP Camera

Easy to management and low cost

Nowadays managed PoE switches are becoming the new trend. The more advanced, managed PoE switches allow the operating power of each camera to be controlled remotely from any point in the IP camera systems. That enables administrators to reboot any non-responding PoE IP camera without going to the camera’s location, saving cost and labor.

Long runs

Connected with a PoE switch, IP cameras can be installed anywhere, even to reach and remote locations. With a single Cat5e cable, the distance of running PoE IP camera can be up to 100m. If longer runs are required, PoE repeaters may be needed.

Resilience to power failure

Usually all IP cameras are powered from one single source (the PoE switch). Therefore attaching a central UPS (Uninterruptable Power Supply) to the PoE switch can ensure continued surveillance in the event of a power cut.

How to Use PoE Switch for IP Camera Systems

Some users are under the assumption the IP systems are too complex. Here we take FS.COM 8-port PoE gigabit managed switch as an example to illustrate how to connect the PoE switch with IP cameras.

In this picture, different types of IP cameras, router and NVR (Network Video Recorder) are connected to the 8-port PoE switch.

Here are the steps.

Connect the router to the LAN port on the 8-port PoE switch using an Ethernet cable (cat5e or cat6);

Connect the power cable to the PoE switch and to a power outlet or surge protector.

Connect IP cameras to port 1~8 on the PoE switch using the Ethernet extension cables.

Add the cameras to the NVR to view the cameras and enable recording. If long distances are required, connect the router to the Internet.

Deploying PoE Switch for IP Camera Systems

In modern society, no matter at home, business network, or public areas, IP camera security systems are playing, and will continue to play an important role in protecting the safety of people. The combination of PoE and IP cameras can offer an ideal solution for this process.

PoE Switch for Home IP Camera System

Many consumers find the need to get a PoE IP camera system for their home, or property, deploying IP cameras may be the best choices. Cameras linked with PoE switches are convenient for users to install and eliminate unnecessary cables. With the development of IP camera systems, more intelligent IP cameras will be used in home IP security systems.

PoE Switch for Business IP Camera System

It’s no doubt that security is imperative for any business in modern society. IP camera security system offers an optimal solution to protect most businesses. Both a mid-sized company and a large company need more than one IP cameras for their IP camera security system. In this condition, the port number of PoE switches is a good solution. 24-port PoE switch may be suitable for mid-sized network, 48-port PoE managed switches can meet requirements of large businesses like international hotel or companies.


PoE switch offers simple and cost-effective wiring to power different IP camera systems. And for some IP camera security systems, using PoE switches can expand the system to the maximum number of cameras. FS.COM provides managed PoE switches with 8-port, 24-port and 48-port for different IP camera security systems. For more details, please read this article: Extend Your Network With PoE Switch
