How Many Watts Does an IP Camera Use with IR?
If you’re setting up a home security system or upgrading your business surveillance, one of the first questions you might ask is: “How many watts does an IP camera use with IR?” It sounds simple, but the answer isn’t one-size-fits-all. The wattage depends on several factors—resolution, infrared range, power delivery method, and whether the camera is actively using night vision. Understanding this can help you make smarter decisions about installation, wiring, and long-term energy costs.
Let’s break it down. An IP camera with IR (infrared) lighting is a type of network camera that can record in full color during the day and switch to black-and-white night vision using built-in IR LEDs. These LEDs illuminate dark areas so the camera can still capture clear footage after sunset. But turning those LEDs on increases power consumption. So yes—using IR does add to the total wattage draw. But how much exactly? Let’s explore.
Understanding IP Cameras and Infrared Technology
What Is an IP Camera with IR?
An IP camera, short for Internet Protocol camera, is a digital video camera that sends data over a network. Unlike analog cameras, which require coaxial cables and DVRs, IP cameras connect via Ethernet or Wi-Fi. They offer higher resolution, remote access, and advanced features like motion detection and two-way audio.

Most IP cameras come equipped with IR LEDs (light-emitting diodes). These emit invisible infrared light, bouncing off objects in the dark and allowing the camera sensor to “see” in complete darkness. When there’s enough visible light, the IR LEDs turn off, and the camera records in color. At night, they switch on automatically, increasing power usage.
Why Does IR Increase Power Usage?
Infrared LEDs are efficient, but they do require electricity. Each LED draws a small amount of current, and modern cameras often have dozens or even hundreds of them. For example, a camera with a 30-meter IR range may use 150+ LEDs. While each one uses just a few milliwatts, together they can add 3 to 6 watts to the total load.
This means that during daylight hours, a typical IP camera might use only 3–5 watts. But at night, when the IR LEDs are active, consumption can jump to 7–12 watts—sometimes more for high-end models.
Typical Wattage Range for IP Cameras with IR
Average Power Consumption
The average IP camera with IR uses between 3 and 12 watts under normal operating conditions. Here’s a rough breakdown:
- Low-power models (1080p, basic IR): 3–5 watts
- Mid-range models (2MP–4MP, improved IR): 5–8 watts
- High-resolution models (4K, long-range IR): 8–12 watts
These numbers include both the camera’s processing unit and the IR LEDs. Some budget models might dip below 3 watts, while professional-grade systems can exceed 12 watts, especially if they include PTZ (pan-tilt-zoom) motors or heaters.
Factors That Influence Wattage
1. Resolution
Higher resolution means more pixels to process. A 4K camera captures four times as many pixels as a 1080p model, requiring more power for image processing and storage. This adds 1–3 extra watts compared to lower-res models.
2. Infrared Range
The farther the IR reaches, the more LEDs are needed. A camera with a 50-foot IR range uses fewer LEDs than one with a 100-foot range. Long-range models often consume 2–4 watts more due to additional lighting.
3. Power Delivery Method
Cameras powered by PoE (Power over Ethernet) draw all their power from the network cable. A standard PoE injector provides 15.4 watts (IEEE 802.3af), which is usually enough for most IP cameras with IR. However, some high-power models require PoE+ (802.3at), delivering up to 30 watts.
4. Motion Detection and Smart Features
Advanced features like AI analytics, two-way audio, or scheduled recording can increase idle power consumption. Even when not using IR, these functions keep the processor active, adding 0.5–2 watts.
5. Ambient Temperature
Cold weather can cause cameras to use extra power for internal heating. Some outdoor models include built-in heaters that can add 1–3 watts during winter months.
PoE vs. DC Power: Which Uses Less Energy?
Power over Ethernet (PoE)
PoE is one of the most popular ways to power IP cameras. It delivers both data and electricity through a single Ethernet cable. A standard PoE switch or injector supplies up to 15.4 watts (802.3af) or 30 watts (802.3at).
Advantages of PoE:
- Simplifies wiring—no need for separate power cables
- Supports remote power cycling (useful for troubleshooting)
- Centralized power management via network switches
However, PoE efficiency depends on cable length and quality. Longer runs (over 100 meters) can lose 10–20% of power. Also, PoE doesn’t work over Wi-Fi—only wired Ethernet.
DC Power Adapters
Many IP cameras also come with a 12V or 24V DC adapter plugged into a wall outlet. These are common in older or budget systems.
Pros:
- Widely compatible with existing wiring
- No dependency on network switches
Cons:
- Requires more cabling and outlets
- Harder to manage across large installations
- Slower to troubleshoot power issues
In terms of energy use, both methods deliver the same wattage to the camera. The difference is in convenience and infrastructure, not efficiency.

How to Reduce Power Consumption
Choose Energy-Efficient Models
Look for cameras labeled ENERGY STAR or with low-wattage specifications. Brands like Dahua, Reolink, and Amcrest offer models optimized for power savings without sacrificing image quality.
Use Motion-Activated Recording
Instead of recording 24/7, enable motion detection. This reduces CPU load and keeps IR LEDs off when no activity is detected. You’ll save 30–50% on energy costs.
Optimize IR Settings
Some cameras let you adjust IR intensity or set a cutoff temperature (e.g., IR turns on only below 10°C or 50°F). This prevents unnecessary nighttime lighting in mild climates.
Upgrade to Smart Lighting
Combine your camera with smart outdoor lights. Turn on lights only when motion is detected, reducing reliance on IR and improving visibility.
Monitor and Manage Usage
Use a smart plug or energy monitor (like Kill A Watt) to track real-time wattage. You might discover a camera drawing far more power than expected—possibly due to a faulty component or outdated firmware.
Cost Implications of Camera Power Usage
Daily and Monthly Energy Costs
Let’s do a quick calculation. Suppose your camera uses 8 watts at night and 5 watts during the day. Over 24 hours:
- Total daily watt-hours = (8 × 6) + (5 × 18) = 48 + 90 = 138 Wh
- At $0.12 per kWh = 0.138 kWh × $0.12 = $0.0166 per day
- Monthly cost = $0.0166 × 30 = $0.50
That’s less than a penny a day! Even with 10 cameras, monthly cost stays under $5. So while wattage matters for efficiency, it rarely impacts your electricity bill significantly.
Long-Term Considerations
Over a year, 10 cameras drawing 8 watts each could cost around $60 in electricity. But consider the bigger picture:
- PoE reduces labor costs (one cable vs. two)
- Remote management saves technician visits
- Reliable power delivery improves uptime
In commercial settings, even small power savings add up. Plus, energy-efficient cameras often last longer and perform better under stress.
