How Do PoE Security Cameras Work: Is It Right for You?

When it comes to talking about security cameras, PoE is one of the most famous options. It’s a great way to save time and effort to get everything sorted and on the road again!

What’s more beneficial is that PoE cameras use a single Ethernet cable to directly connect to the network. That lets it create a stable and faster connection for quick data transmission. Besides, making it easy to install, and line up for maintenance.

That’s said today we’ll walk you through an extensive informative guide on how do PoE security cameras work. We’ll find out if it’s the right fit for you or not.

So let’s dig down into that!

What Does PoE Means?

PoE stands for Power over Ethernet. So cameras that support Ethernet cables for connecting to the network are called PoE cameras. You can use them for home, or academic area surveillance whatsoever!

Unlike other security solutions, the installation procedure isn’t much of a hassle. You can have it directly connected to the home network through the Ethernet cord. So that makes the entire setup process faster, and stable easily enough!

How Do PoE Cameras Work

The system Power-over-Ethernet uses Cat-5, Cat-5e, or Cat-6 cables for networking. So by a single cord, you can simply connect to the internet and power outlet as well. If you haven’t set a PoE power switch line in your IP camera, there won’t be any power but the network.

Sometimes IP cameras might lose the signal strength depending on the nature of the surrounding. However, if that’s connected through Ethernet, it’ll always maintain a stable network connection. That’s why PoE is really essential if you’re not sure about the router is sending a strong single or not.

Moreover, wireless data transmission isn’t faster than wired connections. So the Ethernet cable will transmit the data faster and save it to the storage.

For the most part, it’s easy to setup a Power over Ethernet cable to your existing security camera. This will give you the full advantages of a splitter converting separate lines. Also, if you’ve multiple cameras, use a PoE switch to accommodate the extra number of ports.

You can always adopt an additional adapter to create a bridge of power. The adapter switch will have the connection of electric power and from the router. Later on, you’ll just follow up with a single Ethernet cable to connect to the camera.

Just ensure the type of camera you have and define the components and type of PoE you’ll need. That’s said, here’s the 2 different types explained really well!

Types of PoE Networks

There’re two main types either standard or PoE+.

Standard PoE

This type is generally found on most IP cameras. It’s specified as IEEE 802.3af that’s based on 48 volts. It’s configured through a 4 or 8-wired twisted pair connection. And you’ll be able to send electricity power up to 15-watt.

While this is good for basic IP cameras, a PTZ camera requires a more powerful connection over the Ethernet cable. Or, if you have a higher-end camera using outdoor, standard PoE might not be able to send the right electricity power to cool off the heaters.


It’s specified as IEEE 802.3at and the connection will suit higher-end cameras requiring more power to operate properly. You’ll get up to 30-watt electric power. However, it’ll require setup a more functional switch than what’s used in the standard wiring.

Cat 5 vs. Cat 6: What’s the Difference?

Both are some of the most used PoE cables to setup the network between camera and router. Hence, Cat means Category and the number indicates its power of data transmission. You can use either Cat 5 or Cat 6 depending on the distance of data transmission.

They support various bandwidth control and speed. All of them can be used within the same network. So you can use them for most IP cameras.

However, Cat 6 will provide you a more reliable and faster connection. It’s more durable and recommended for better performance.


That’s it about how do poe cameras work! We’ve tried to explain everything in-depth as we possibly could. And we highly expect most of you to feel a little more confident setting up a PoE for your security solutions.

The installation process is very easy with just one single, YET right cable for the camera. So you can easily avoid messing up with lots of wires and have fun! If you wind up with any questions, don’t hesitate to leave us a comment below. We’ll try to get back with an answer AS SOON AS POSSIBLE
