PoE Video Doorbell Explained: Best PoE Options, Wired & Battery Alternatives

A video doorbell lets you see who's at your door from anywhere, but not all models are built the same. A PoE video doorbell, short for Power over Ethernet, connects through a single Ethernet cable that supplies both power and internet, offering stable performance without the need for Wi-Fi or batteries. It’s a reliable option for homes that want consistent video quality and fewer interruptions.

This guide explains what a PoE video doorbell is, how it works, and how it compares to traditional wired and battery models. You’ll also find a side-by-side comparison chart and a look at top-rated options across all types to help you choose the best fit for your home.

What Is a PoE Video Doorbell and How Does It Work?

A PoE video doorbell is a type of smart doorbell camera that uses Power over Ethernet (PoE) technology to combine power delivery and data transmission through a single Ethernet cable, typically Cat5e or Cat6. PoE doorbells eliminate the need for separate power adapters or frequent battery changes, offering a more reliable and consistent setup compared to wireless alternatives.

The operation is fairly straightforward. The doorbell connects via Ethernet to a PoE switch, PoE injector, or compatible router. This single cable supplies low-voltage power (in accordance with IEEE 802.3af or 802.3at standards) while simultaneously transmitting video, audio, and motion alerts to your smartphone app or connected security system.

When someone approaches your door or presses the bell, the camera activates instantly and sends real-time notifications. More advanced models also offer person detection, which can reduce false alerts triggered by pets, passing vehicles, or shadows. Most PoE models also include high-resolution cameras, night vision, and compatibility with smart home platforms such as Amazon Alexa or Google Assistant.

Pros and Cons of Using a PoE Video Doorbell

If you want to know whether a PoE video doorbell is right for your security needs, it’s important to weigh both its benefits and limitations. Below is a clear breakdown of the advantages and drawbacks.

Pros:

• Ethernet provides a stable, interference-free connection, unlike Wi-Fi signals that can weaken due to walls or network congestion.
• A PoE video doorbell requires no batteries to recharge or replace, enabling true 24/7 operation and continuous recording.
• Support high-definition video, advanced motion detection, and seamless integration with NVR systems for professional-grade surveillance.
• Once installed, PoE doorbells require minimal ongoing maintenance compared to battery-powered models.
• Support speeds of up to 1 Gbps, allowing smoother live streaming and faster alert delivery.

Cons:

• A PoE video doorbell requires Ethernet cabling, which may need drilling, wall routing, or professional installation.
• The installation locations are restricted to areas where Ethernet cables can reach.
• PoE video doorbells and supporting equipment (such as PoE switches) typically range from £100-£300, excluding installation fees.
• Standard Ethernet cable runs are limited to approximately 330 feet before signal performance degrades.
• The PoE video doorbell market is smaller compared to Wi-Fi or battery-powered alternatives, with fewer options available.

FAQs

Is there a PoE doorbell camera?

Yes, PoE doorbell cameras are designed to deliver power and data through a single Ethernet cable. This wired connection ensures stable performance without relying on Wi-Fi signals or batteries.

PoE doorbells are commonly used in homes that already have Ethernet wiring or in professional security setups where reliability is critical.

Popular PoE doorbell options include models from brands like Ring and Reolink, which are available in the UK and support high-resolution video and advanced motion detection.

Are PoE doorbells better?

PoE doorbells can be better for users who want maximum reliability and uninterrupted performance. Because they use a wired Ethernet connection, which can avoid Wi-Fi interference and provide constant power for consistent monitoring.

This makes PoE doorbells well-suited for larger homes, busy networks, or areas with weak wireless coverage.

However, they require more complex installation, so for many homes, traditional wired or battery doorbells may offer a more practical balance of convenience and performance.

Is there a PoE Ring doorbell?

Yes, Ring offers a PoE-compatible option with the Wired Doorbell Pro (3rd Gen). This model supports PoE Plus for stable power delivery and dependable connectivity.

It features high-resolution video, advanced motion detection, and seamless integration with Amazon Alexa for smart home control.

Is PoE video doorbell better than WiFi?

A PoE video doorbell is often more reliable than a Wi-Fi model because it uses a direct Ethernet connection. This eliminates signal drops, reduces latency, and allows faster, more consistent data transmission.

PoE doorbells are ideal for environments where Wi-Fi coverage is unreliable or heavily congested.

That said, Wi-Fi doorbells are easier to install and offer greater placement flexibility, making them a better choice for renters or homes without Ethernet wiring.
