The Power Behind Your Surveillance: Why Choosing the Right PoE Switch for UniFi Cameras Matters
Imagine this: you’ve invested in a sleek, high-resolution UniFi camera system to monitor your home, business, or property. You’ve carefully placed each camera for optimal coverage, downloaded the UniFi Protect app, and are ready to enjoy peace of mind—only to find that your cameras keep dropping offline, rebooting, or failing to power on at all. The culprit? A mismatched or underpowered Power over Ethernet (PoE) switch. While it’s easy to focus on the cameras themselves, the backbone of any reliable UniFi surveillance network is the PoE switch that powers and connects them. In 2024, with UniFi releasing new camera models with higher power demands and advanced features like AI detection and 4K streaming, selecting the right PoE switch is more critical than ever.
Power over Ethernet (PoE) technology simplifies network deployment by delivering both data and electrical power over a single Ethernet cable. This eliminates the need for separate power adapters and outlets, making installations cleaner, faster, and more scalable. However, not all PoE switches are created equal. Some support only older PoE standards (like 802.3af), while others deliver higher power (802.3at and 802.3bt) required by modern UniFi cameras such as the G4 Pro, G5 Flex, or AI-powered models. Choosing the wrong switch can lead to underpowered cameras, network instability, or even hardware damage. This guide will walk you through everything you need to know to select the best PoE switch for UniFi cameras in 2024, ensuring your security system runs smoothly, efficiently, and without interruption.
Understanding PoE Standards and UniFi Camera Power Requirements
PoE Basics: 802.3af, 802.3at, and 802.3bt Explained
Before diving into specific switch models, it’s essential to understand the different PoE standards and how they align with UniFi camera power needs. There are three main IEEE standards that govern PoE delivery:

- 802.3af (PoE): Delivers up to 15.4W per port, with 12.95W available to the device after power loss. Suitable for basic cameras like the UniFi G3 series.
- 802.3at (PoE+): Provides up to 30W per port (25.5W usable). Ideal for mid-range models such as the G4 Dome and G4 Bullet.
- 802.3bt (PoE++): Offers up to 60W (Type 3) or 100W (Type 4) per port. Required for high-performance cameras like the G4 Pro, G5 PTZ, and AI-powered variants.
For example, the UniFi G4 Pro draws up to 24W under normal conditions and can peak at 30W during IR night mode or PTZ movement—exceeding the 802.3af limit. Using an 802.3af switch here risks underpowering, leading to reboots or shutdowns.
UniFi Camera Power Consumption Breakdown
Different UniFi camera models have varying power demands. Here’s a quick reference for popular 2023–2024 models:
- UniFi G4 Dome: 12.5W (PoE+ recommended)
- UniFi G4 Bullet: 13W (PoE+)
- UniFi G4 Pro: Up to 30W (PoE++ Type 3 required)
- UniFi G5 Flex: 12W (PoE+)
- UniFi G5 PTZ: Up to 40W (PoE++ Type 3)
- UniFi AI Bullet (G5 AI): 15–20W (PoE+ with headroom)
Pro Tip: Always check the official Ubiquiti support page for the latest power specifications. Some cameras may have firmware updates that alter power draw.
Why Power Budget Matters
Every PoE switch has a total power budget—the sum of power it can deliver across all ports. For instance, a 24-port switch with a 150W budget can’t power 24 G4 Pro cameras (each needing 30W), since that would require 720W. You must calculate your total power needs and ensure the switch can handle peak loads (e.g., all cameras using IR simultaneously).
Top PoE Switches for UniFi Cameras in 2024: A Detailed Comparison
Ubiquiti UniFi Dream Machine Pro (UDM Pro) with Built-in Switch
The UDM Pro is a hybrid device combining a network gateway, router, and 8-port PoE switch. It supports:
- 8x Gigabit PoE+ ports (up to 150W total)
- 2x SFP+ ports for fiber uplinks
- UniFi OS integration with native Protect app support
Best For: Small to medium deployments (up to 8 cameras). Ideal for homes or offices where you want a unified UniFi ecosystem. The UDM Pro powers G4 Dome/Bullet cameras effortlessly but cannot support G4 Pro or G5 PTZ due to PoE++ limitations.
Example Use Case: A homeowner installing 6 G4 Dome cameras and 2 G5 Flex units. The UDM Pro handles all with 120W used (leaving 30W buffer).
UniFi Switch Pro 24 PoE (USW-Pro-24-POE)
This 24-port managed switch is a powerhouse for larger setups:
- 24x Gigabit PoE+ ports (802.3at)
- 4x 10G SFP+ uplinks
- 500W total PoE budget
- Layer 3 routing and VLAN support
Best For: Businesses, multi-dwelling units, or homes with 10–20 cameras. The 500W budget allows powering 16 G4 Pro cameras (16 x 30W = 480W). However, it lacks PoE++ ports, so it’s not suitable for G5 PTZ (40W) or future 60W+ models.
Tip: Use the Port Isolation feature to segment camera traffic and improve security.
UniFi Switch Pro 48 PoE (USW-Pro-48-POE)
Scaling up further, this 48-port model is perfect for enterprise-level deployments:
- 48x Gigabit PoE+ ports
- 8x 10G SFP+ uplinks
- 950W PoE budget
- Redundant power supply option
Best For: Large properties, campuses, or retail stores with 20+ cameras. It can power 31 G4 Pro cameras (31 x 30W = 930W), leaving room for future expansion.
Real-World Example: A 50-camera warehouse uses two USW-Pro-48-POE switches. Each powers 25 G4 Bullet and Dome cameras, with 10G uplinks to a core switch for video analytics.
UniFi Switch Enterprise 24 PoE (USW-Enterprise-24-POE)
The first PoE++ switch in the UniFi lineup (2023 release), this 24-port model is a game-changer:
- 24x Gigabit PoE++ ports (802.3bt Type 3)
- 4x 2.5G/10G SFP+ uplinks
- 720W PoE budget
- Advanced QoS and storm control
Best For: High-density, high-power camera networks. It can power 18 G5 PTZ cameras (18 x 40W = 720W) or mix G4 Pro, G5 AI, and PTZ models. The 2.5G uplinks reduce bottlenecks for 4K video streams.
Why It’s 2024’s Top Pick: Future-proofed for upcoming 60W+ cameras and supports AI workloads without throttling.
Key Features to Look for in a PoE Switch for UniFi Cameras
PoE Port Count and Power Budget
Match the number of ports to your camera count, but always plan for 20–30% overhead for future expansion. For example:
- 10 cameras → 16-port switch
- 25 cameras → 32-port switch
- 50+ cameras → Stackable switches (e.g., two 24-port units)
Calculate your total power budget by summing each camera’s max draw and adding 20% for surges (e.g., 10 x 30W G4 Pro = 360W required; choose a 450W+ switch).
Managed vs. Unmanaged Switches
Unmanaged switches are plug-and-play but lack features like VLANs or traffic monitoring. Managed switches (like all UniFi Pro models) offer:
- Remote configuration via UniFi Network app
- VLAN segmentation to isolate camera traffic
- Port prioritization (QoS) for smooth video streaming
- PoE scheduling (e.g., turn off cameras at night)
Example: A retail store uses VLANs to separate POS systems from cameras, preventing bandwidth competition.
Uplink Speed and Backplane Capacity
Cameras generate massive data—especially 4K models. Ensure:
- Uplink ports: 10G SFP+ for core switches (e.g., USW-Pro-24-POE)
- Backplane capacity: ≥ 1 Tbps for 48-port switches to avoid bottlenecks
A 24-camera system streaming 4K video can generate 200+ Mbps per camera. A 1G uplink would saturate, causing lag. A 10G uplink handles it easily.
Redundancy and Reliability
For mission-critical systems, look for:
- Dual power supplies (e.g., USW-Pro-48-POE with optional PSU)
- Hot-swappable fans for continuous operation
- LLDP-MED for automatic device detection and power negotiation
Tip: Use a UPS (Uninterruptible Power Supply) to keep switches running during outages.
Installation and Configuration Tips for Optimal Performance
Proper Cable Selection and Distance
PoE performance degrades over long cable runs. Follow these rules:
- Use Cat 6 or Cat 6a cables for 100m max runs
- Avoid daisy-chaining PoE extenders
- Keep cables away from electrical wiring to reduce EMI
Example: A 90m run with Cat 6 delivers full PoE power, but a 110m run with Cat 5e may drop voltage below 44V (the minimum for PoE+).
UniFi Network App Configuration
After connecting your switch:
- Log in to the UniFi Network app or web console
- Assign a static IP to the switch
- Create a VLAN for cameras (e.g., VLAN 10)
- Enable PoE Priority (High for critical cameras)
- Set Port Isolation to prevent camera-to-camera attacks
Pro Tip: Use the Port Scheduling feature to power down outdoor cameras during business hours (reducing energy use by 30%).
Monitoring and Maintenance
Use the UniFi app to:
- Monitor real-time PoE usage per port
- Set alerts for over-temperature or power overload
- Check camera connectivity and uptime
Schedule monthly checks for:
- Dust buildup (clean fans and vents)
- Cable integrity (replace frayed cables)
- Firmware updates (ensure latest switch and camera firmware)
