Security cameras are no longer a luxury; they’ve become a must-have for keeping homes and businesses safe. While traditional CCTV systems still hold their place and Wi-Fi cameras are popping up everywhere, there’s another option gaining ground: PoE cameras.
So, what is PoE camera, exactly? Well, PoE stands for Power over Ethernet, a method that delivers both power and data through a single cable. This drastically simplifies installation and increases reliability. In this guide, we’ll break down what you need to know about PoE cameras and why they might be the smarter choice for your security setup.
What Is a PoE Camera?
So, what is a PoE security camera, exactly?
A PoE (Power over Ethernet) camera is a type of IP (Internet Protocol) camera that uses a single Ethernet cable to both power the device and transmit video data to a central recording system, such as a Network Video Recorder (NVR). This drastically reduces wiring complexity and improves installation flexibility.
Unlike traditional analogue CCTV cameras than need separate power supply and coaxial data cables, PoE cameras streamline everything into one connection, ideal for both home and business surveillance systems.
Now, what is a PoE camera system? In most cases, a complete setup consists of:
- One or more PoE cameras
- Cat5e or Cat6 Ethernet cables
- A Network Video Recorder (NVR)
- PoE switches (optional)
- A router
- A monitor or mobile app for live viewing, recorded playback, and system controls
Types of PoE Cameras
When learning what is a PoE IP camera, it’s important to know that there are several types available, each designed to serve different environments and use cases. Let’s take a look:
Bullet PoE Cameras
Long and cylindrical, bullet PoE cameras are designed to be highly visible deterrents. Their shape allows them to focus on specific areas like driveways or entrances, and they often come with weatherproof housings for outdoor use.
Dome PoE Cameras
Compact and dome-shaped, these sit neatly on ceilings or walls and make it harder for anyone to see which way the lens is pointing. They’re often chosen for indoor spaces or areas where a discreet look is preferred.
Turret PoE cameras
Also known as “eyeball” cameras, these offer the same discreet appearance as domes but with a flexible ball-and-socket design for easy angle adjustment.
PTZ PoE Cameras
Short for Pan-Tilt-Zoom, these motorised camera units can rotate and tilt to scan large areas and zoom in for detailed views, making them ideal for covering expansive spaces with fewer devices.
Multi-Imager PoE Cameras
These house multiple lenses or sensors in a single unit to capture wide panoramic or 360° views. By stitching images from each lens together, they can monitor larger areas without leaving blind spots, perfect for open-plan spaces or car parks.
PoE power levels also vary:
- Standard PoE (802.3af) provides up to ~15W for basic fixed cameras.
- PoE+ (802.3at) delivers up to ~30W for more advanced devices with motorised lenses or heaters.
- PoE++ / Hi-PoE (802.3bt) supports ~60–90W for high-powered PTZ and multi-imager models.
Benefits of PoE Security Cameras
PoE cameras bring a host of practical advantages that make them stand out from traditional CCTV and Wi-Fi systems:
- One-cable setup: Power and data travel over a single Ethernet cable, making installation faster and tidier.
- Lower installation costs: There’s no need for additional electrical wiring or outlets near each camera, which reduces labour and materials.
- Longer cable runs: Ethernet supports distances up to 100 metres without signal loss, far beyond the reach of standard low-voltage adapters.
- Centralised power control: A PoE switch allows you to back up your entire camera system with a single UPS, reboot devices remotely, and monitor power usage from one place.
- Stable and secure connections: Unlike Wi-Fi cameras, PoE devices are immune to wireless interference and provide consistent video quality.
- Scalable and future-proof: Adding more cameras is as simple as plugging into another port on the PoE switch or NVR.
What’s the Difference Between PoE and Wireless IP cameras?
When comparing PoE cameras and wireless IP cameras, the biggest differences come down to how they’re powered, connected, and how reliably they perform in different environments.
Both options have their place, but understanding these distinctions will help you choose the right solution for your needs.
Power and Cabling
PoE cameras use a single Ethernet cable to deliver both power and data, connecting directly to a PoE-enabled switch or recorder. This eliminates the need for separate power supplies at each camera location.
In contrast, wireless IP cameras still require a power source—either via mains adapters or batteries, sometimes with added solar panels—since only their data travels over Wi-Fi.
Connectivity and Reliability
A hardwired PoE connection provides a stable and interference-free link, unaffected by Wi-Fi congestion or weak signals.
Wireless IP cameras depend on your home or office Wi-Fi network, which can suffer from dropouts if the signal is obstructed by walls, appliances, or other devices competing for bandwidth.
Bandwidth and Image Quality
PoE systems run on gigabit Ethernet, allowing them to handle high-resolution streams, including 4K video, without buffering. Wireless cameras often compress footage or limit resolution to maintain performance over the network.
Looking for a reliable PoE system that can actually harness all that bandwidth to your advantage? the eufy PoE NVR Security System S4 Max is worth considering. Pairing eufy 16MP PoE Cam S4 units and the NVR S4, this Amazon best-selling nvr cctv camera system boasts:

Recording Capability
Most PoE cameras are designed for continuous 24/7 recording, storing weeks or months of footage on an NVR. This makes them ideal for monitoring high-traffic areas or critical sites where gaps in coverage aren’t acceptable.
Wireless IP cameras, on the other hand, often record only when motion is detected to conserve bandwidth and power, ideal for home security setups.
Installation Effort
PoE requires Ethernet cabling, which can take more time to install but results in a permanent, professional setup.
Wireless cameras are quicker and easier to mount and configure by yourself, making them suitable for temporary setups or areas where running cables isn’t practical.
For smaller homes, rental properties, or areas where cabling isn’t practical, wireless cameras provide fast and flexible installation. eufy’s solar-powered outdoor cameras are excellent examples:

Perfect Use Cases for PoE Security Cameras
PoE cameras are designed for flexibility and performance, making them ideal for a wide range of environments. Here’s where they stand out the most:
- Larger or more complex homes: PoE cameras are ideal for detached houses with multiple entry points, long driveways, or expansive gardens, as well as multi-storey properties where Wi-Fi signals often struggle between floors.
- Apartment blocks and office buildings: In high-density areas where Wi-Fi is crowded with dozens of networks, PoE delivers consistent video streams without buffering or dropouts.
- Large warehouses and industrial sites: In expansive spaces filled with machinery or metal racking, Wi-Fi signals often struggle to reach every corner. PoE ensures stable, high-bandwidth connections for monitoring large floor areas without interruption.
- Multi-site businesses: For offices, retail chains, or campuses, PoE allows all cameras to be powered and managed centrally. A single UPS can provide backup power, and IT teams can monitor feeds across multiple locations from one system.
- Car parks and building perimeters: PoE enables long cable runs to outdoor poles or walls without worrying about power sockets. This makes it easier to monitor entrances, exits, and vehicle lanes effectively.
- Critical 24/7 operations: Banks, data centres, and other facilities that can’t afford downtime benefit from PoE’s ability to run 24/7.
Conclusion
PoE cameras are changing the way we think about security, offering reliable performance without the headaches of complex wiring or flaky Wi-Fi connections. Now that you know what a PoE camera is and how it stacks up against other options, you’re in a strong position to decide if it’s the right fit for your needs.
