In this comprehensive guide, we will provide you with a thorough understanding of what PoE IP cameras are and how they can revolutionize your security experience. You will find what you want here whether you are new to the PoE camera or a pro.

What Are PoE Cameras

A PoE camera is a type of IP-based security camera that uses Power over Ethernet (PoE) technology to transmit both power and data via a single cable, such as CAT5, CAT5E, CAT6, etc.

These types of Ethernet cables are specifically designed to support the requirements of Power over Ethernet technology, which is governed by the IEEE 802.3 standards. Only these cables are capable of carrying both power and data and allow for distances up to 100 meters (328 feet).

PoE cameras streamline the installation process and reduce the need for multiple cables, making them a popular choice for modern security systems. And due to their easy-to-setup feature, PoE security cameras are often called plug-and-play cameras.

PoE cameras come with a variety of features, depending on the model, such as motion detection, night vision capabilities, digital noise reduction, wide dynamic range imaging, and more. Additionally, some models are equipped with two-way audio so users can communicate with people captured by the camera.

Thanks to their extraordinary features and reliable performance, PoE security cameras have become an increasingly attractive option for residential and commercial security applications.

For example, PoE technology has combined with 16MP resolution. Reolink has launched its first 16-megapixel dual-lens security camera, the Duo 3 PoE. Designed to elevate surveillance solutions professionally, this camera promises some exciting surprises.

How Do PoE Security Cameras Work

Many beginners expect a PoE camera to work by simply connecting it to their home router with an Ethernet cable. That’s correct only when they use a CAT5 or higher-category Ethernet cable and the router support PoE.

In cases when your router doesn’t support PoE or you want to manage multiple PoE cameras, you need to utilize other devices such as a PoE injector or PoE switch.

A PoE injector can add Power over Ethernet (PoE) capabilities to a non-PoE network switch or router. Similarly, a PoE switch has built-in PoE capabilities and can provide both power and data transmission to PoE cameras. Their main difference is that a PoE switch comes with multiple ports to support several PoE devices simultaneously, while a PoE injector can only support one PoE camera.

Best PoE Cameras: How to Choose

Choosing the best PoE security camera for your security and surveillance needs involves evaluating various factors and features. Here are some key considerations to help you select the ideal PoE camera:

1. PoE Standard

The PoE standard determines the power output that the camera can receive and ensures compatibility with your existing PoE equipment. There are two common PoE standards: IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards. The IEEE 802.3af standard provides up to 15.4 watts of power per port, while the IEEE 802.3at standard offers up to 25.5 watts.

The 802.3at as a newer PoE standard is backward compatible with the 802.3af standard, which means that devices supporting the 802.3at standard can also supply power to devices designed for the 802.3af standard. To avoid compatibility issues, it's essential to choose a PoE camera that matches the PoE standard of your existing equipment, such as PoE switches or injectors.

2. Image Quality

Consider the resolution of the PoE camera, as it directly impacts the clarity and detail of the footage. Common resolutions include 1080p (2MP), 3MP, 4MP, 5MP, and 4K (8MP). Higher resolutions like 4K provide better image quality but may require more storage space and bandwidth.

3. Field of View

The field of view (FOV) determines the area the camera can cover. Wider FOVs enable monitoring of larger areas, while narrower FOVs are suitable for focusing on specific points or entryways. If you want to monitor a large area, choose a wide-angle PoE camera.

4. Night Vision

Evaluate the camera's night vision capabilities, as it is crucial for capturing clear footage in low-light conditions and providing 24/7 home security. Look for cameras with infrared (IR) LEDs and check their effective range to ensure adequate coverage in the dark. In this way, you won’t miss anything both day and night.

5. Remote Access & Compatibility

Ensure the PoE camera is compatible with your existing security system or NVR and offers remote access through a user-friendly app or web interface. This is necessary for you to view live feeds and manage settings from anywhere.

6. Weather Resistance

If you plan to install the camera outdoors, make sure it has a suitable IP (Ingress Protection) rating to withstand harsh weather conditions, such as rain, snow, or dust. An IP66 rating or higher is recommended for outdoor cameras.

7. Budget

Determine your budget for the PoE camera and compare the features and performance of various models within your price range. Keep in mind that a higher initial cost may be offset by long-term savings from simplified installation and centralized power management.

How to Set up Best PoE Security Cameras & Systems

There are 3 simple solutions for you to get your PoE security camera to work in whatever situation. To make things easy to understand, we’ll take Reolink PoE cameras for example.

Solution 1: Plug and play when your home router supports PoE

Technically, you only need to connect your PoE security cameras to the router that supports PoE with an Ethernet cable, and then your PoE camera will start to work. This is a plug-and-play solution even for beginners.

If you need larger storage with a PoE home security camera system, just add an NVR to your router.

Solution 2: Use a PoE injector/PoE switch for IP cameras when the router doesn’t support PoE

Things will be a little more complicated when your router is not PoE featured, or the monitoring areas are out of the reach of existing camera wires. In either case, a PoE injector or PoE switch for IP Cameras will help you get PoE for IP cameras.

Here’s how you can use them to set up a PoE camera system:

With a PoE IP camera injector, you will need to plug the Ethernet cable of the PoE camera into the injector, connect the injector to your router, and then power the injector. And the work is done.

Note: Mind that the PoE injector normally provides only one PoE camera, as mentioned above. So if you have multiple PoE cameras, add a network switch to the system, or just turn to a PoE switch instead.

With a PoE camera switch, you only need to plug the Ethernet cable of all the cameras into the switch, connect the PoE switch to the router, and then power the system up.

Solution 3: Add an NVR to the PoE camera system

You may also add an NVR to your PoE camera system for local video storage.

Actually, if you get a complete PoE IP camera system set, which means both PoE security cameras and NVR are provided by one manufacturer, you can simply connect all cameras with the NVR directly via the 8, 16, or even 32 PoE ports on it.

You can also connect the NVR to a router if you want remote viewing or push notifications from the PoE cameras on your phone.

PoE VS Non-PoE Cameras

When considering security cameras for your surveillance system, you may come across PoE and non-PoE cameras. Here, we'll compare the key differences between them to help you make an informed decision.

Wiring and installation cost

PoE cameras receive power and transmit data through a single Ethernet cable. This eliminates the need for extra wiring and has made the installation of PoE cameras less complex, faster, and more cost-effective than ever before.

Non-PoE cameras, on the other hand, require both a power source and an Ethernet connection for data transmission. This leads to more complicated wiring requirements as well as higher installation costs due to the additional cabling needed.

Centralized power management

PoE cameras can be connected to a PoE switch, allowing centralized control and monitoring of the entire surveillance system. This includes remotely rebooting devices, adjusting power allocation, and implementing power backup solutions.

On the other hand, non-PoE cameras often lack centralized power management, making it more challenging to control and monitor the entire surveillance system.

But this is not a big deal as both PoE and non-PoE cameras can be connected to an NVR for easy management.

Maximum cable length

PoE cameras can be installed at distances up to 100 meters (328 feet) from the PoE switch or injector without signal degradation or the need for additional power sources.

However, non-PoE cameras may have shorter maximum cable lengths compared to PoE cameras, which can limit camera placement options and necessitate additional signal repeaters or power sources.

Transmission speed

The transmission speed of both PoE and non-PoE cameras depends on the type of Ethernet cable and network switch used, rather than the cameras themselves.

But some non-PoE cameras, such as WiFi cameras, need to be in the range of the router and their transmission speed tends to be influenced by various factors. Even though non-PoE CCTV cameras send continuous analog signals over coaxial cables with minimal latency, they support the low resolution and might suffer from signal loss over long cable runs.

In general, PoE cameras always ensure stable and fast data transmission even over longer distances (up to 100m). So if you want a security camera system with a reliable connection, PoE cameras are the best choice.

Compatibility and flexibility

Non-PoE cameras can be a better choice for compatibility with existing non-PoE network switches or routers. In cases where upgrading the entire network infrastructure to support PoE is not feasible, non-PoE cameras can be used with separate power sources.

Besides, some non-PoE cameras are wireless, relying on Wi-Fi or a 4G network for data transmission instead of Ethernet cables. This can simplify installation in areas where running cables is difficult or impractical.

While non-PoE cameras may have certain advantages in specific situations, PoE cameras generally provide a more convenient and cost-effective solution for most surveillance applications. But choosing between a PoE or non-PoE camera system will finally depend on individual needs and preferences.

Hot PoE CCTV Camera Q&As

Besides the PoE IP camera installation, there are some other questions that we’ve been frequently asked about as listed below.

What’s the max distance for PoE cameras to work?

It's suggested to use the PoE IP camera under 300 feet (100 meters) to avoid unstable signal issues or possible power attenuation problems. However, you may extend the distance with the help of a PoE switch or PoE injector.

If you are not sure about the max distance your PoE IP camera can go, check that with the camera provider to ensure your plan works well to your requirements.

Can PoE cameras work without the Internet?

Yes, PoE cameras can work without an internet connection. PoE cameras can receive power and transmit data through an Ethernet cable connected to a PoE switch or injector, which is separate from the internet.

Even without Internet access, PoE cameras can record footage locally to an SD card, NVR, or DVR. And you can still view the live feed from your PoE cameras on a local monitor connected to the NVR or DVR. If your PoE cameras are equipped with on-device motion detection features, they will continue to detect movement and trigger alerts.

But it's important to note that while PoE cameras can function without an internet connection, you lose the ability to remotely monitor and control the cameras, receive notifications, and access cloud storage (if available). If these features matter to you, ensure you have a reliable internet connection for your security camera system.
