How to Reduce Security Camera Electricity Usage

Security camera electricity usage is a common concern—but the truth is, modern surveillance systems are among the most energy-efficient devices in your home or business. Unlike appliances like refrigerators or air conditioners, security cameras run 24/7 while drawing minimal power. On average, a single camera uses 2 to 30 watts, with most setups costing just $1 to $9 per month to operate. That’s less than a gaming console, far below your AC bill, and often cheaper than your daily coffee.

Despite running around the clock, security cameras consume surprisingly little electricity. A full 4-camera system with a recorder typically uses less power than a single incandescent lightbulb or desktop computer. This article breaks down exactly how much energy different cameras use, what drives up consumption, and how you can optimize your system to save power—and money. You’ll learn how to calculate your own system’s monthly cost, compare camera types, and make smarter choices that keep your property secure without increasing your electric bill.

How Much Power Do Different Security Cameras Use?

Not all cameras are created equal when it comes to energy use. The wattage varies widely based on type, features, and power source.

Basic Indoor Wired Cameras (2–5W)

These are the most energy-efficient models, ideal for low-traffic indoor areas like hallways or garages. With simple circuitry and no night vision, they draw only 2–5 watts. The Reolink E1, for example, operates at the lower end of this range and is perfect for basic monitoring where high resolution isn’t critical.

Outdoor Cameras with Night Vision (5–10W)

Designed for exterior use, these cameras typically use 5–10 watts. The jump in power comes from infrared (IR) LEDs that activate at night, often doubling energy use after dark. Weatherproofing and built-in heaters in cold climates also contribute to higher draw. Models like the Amcrest Turret and Tapo 2K wireless camera fall into this category.

High-Definition IP Cameras (7–20W)

IP cameras offer 4K video, AI detection, and continuous streaming—but at a higher energy cost. These models consume 7–20 watts due to advanced processing and network transmission. The Reolink RLC-810A, for instance, stays under 12W while supporting person detection and Power over Ethernet (PoE).

Analog CCTV Cameras (2–15W)

Older analog systems are surprisingly efficient, using 2–15 watts. Without Wi-Fi or smart features, they rely on simpler electronics. While they lack the resolution of modern IP cameras, they remain a cost-effective option for basic surveillance.

Plugged-In Wireless Cameras (5–10W)

Despite the “wireless” label, many of these cameras plug into an outlet and use 5–10 watts due to constant Wi-Fi connectivity. Brands like Nest, Ring, and Tapo maintain live streaming and cloud alerts, increasing power draw compared to battery-powered alternatives.

Battery-Powered Cameras (0.5–2W average)

These ultra-efficient models use 0.5–2 watts on average, thanks to sleep modes and motion-triggered recording. When idle, power consumption drops nearly to zero. However, frequent activity or poor signal strength can shorten battery life, increasing recharge frequency and indirect grid usage.

Solar-Powered Cameras (1–3W)

Solar models like the eufy SoloCam S220 or Reolink Go Plus consume 1–3 watts while relying on sunlight for charging. With just 3–6 hours of daily sun, they operate off-grid—eliminating electricity costs. Ideal for remote or eco-conscious installations, they deliver strong performance without draining your power.

PTZ (Pan-Tilt-Zoom) Cameras (15–30+ W)

The most power-hungry cameras, PTZ models draw 15–30+ watts. Motors, optical zoom, and auxiliary heaters (for de-icing) require significant energy, especially during movement. The Axis Q6155-E, for example, peaks at 30W when active—best suited for commercial use where coverage outweighs efficiency.

Doorbell and 360-Degree Cameras

Wired doorbells use 5–10 watts, driven by constant connectivity, LED rings, and chime mechanisms. 360-degree cameras consume 8–15 watts due to multi-lens processing and panoramic stitching. While slightly above average, neither will drastically impact your energy bill.

Power Consumption of Recorders and Accessories

Cameras aren’t the only components using electricity. Supporting hardware adds to your total energy draw.

NVR and DVR Power Draw

Network Video Recorders (NVRs) typically use 10–25 watts, mostly from hard drive operation (~5W) and video processing. Digital Video Recorders (DVRs) can draw more—up to 40–60 watts depending on brand and capacity. A Hikvision DVR may pull 40W, while a Dahua model reaches 60W. This means the recorder alone can add $1.50–$5.00 to your monthly bill.

PoE Switches and Injectors

Power over Ethernet (PoE) delivers data and power through one cable, improving efficiency. Common standards include:

PoE (802.3af): Up to 15.4W per port—ideal for fixed cameras
PoE+ (802.3at): Up to 30W—required for PTZ or heated models
PoE++ (802.3bt): Up to 100W—future-proof for high-demand systems

A well-sized PoE switch reduces clutter and energy loss from multiple wall adapters.

Additional System Components

Other devices contribute to total draw:

Wi-Fi extenders: 5–10W each
External hard drives: 5–10W if not built into the NVR
Integrated security lighting: 10–100W when triggered

While small individually, these accessories can collectively increase system usage—especially in complex setups.

Real-World System Power Examples

See how actual configurations translate into energy costs.

4-Camera Home System (Wired + NVR)

4 × Outdoor IR cameras @ 7W = 28W
NVR with HDD = 25W
Total: 53W
Monthly energy: 53W × 24h × 30d = 38.2 kWh
Cost at $0.13/kWh: $4.97/month

This setup uses less power than a gaming console.

8-Camera Business System (4K IP + PoE+)

8 × 4K IP cameras @ 10W = 80W
NVR with dual drives = 30W
PoE+ switch = 10W
Total: 120W
Monthly energy: 86.4 kWh
Cost: $11.23/month

Even this high-end system costs less than running a refrigerator.

4-Camera Solar Setup (Off-Grid)

4 × Solar-powered cameras = 4W total average
Solar panels handle all charging
Grid usage: Near zero
Ongoing cost: $0

After the initial investment, solar systems eliminate electricity costs.

What Increases Security Camera Power Use?

Several factors can spike your system’s energy draw.

Video Resolution and Frame Rate

Higher resolution (e.g., 4K) increases processing by 2–5W. A 30 fps frame rate uses more power than 10 fps. For most homes, 1080p or 2K at 15 fps offers excellent quality with lower energy demand.

Night Vision Activation

Infrared LEDs can double a camera’s power draw at night. A 5W daytime unit may jump to 10W after dark. Color night vision uses even more.

Smart Detection and AI Features

Cameras with person or vehicle recognition add 2–4W due to onboard processing. While useful, this increases monthly cost by $0.30–$0.60 per camera.

Recording Mode: Continuous vs. Motion-Triggered

Continuous recording: Keeps NVR writing 24/7
Motion-activated: Reduces NVR activity by up to 50%

While the camera stays on either way, motion-triggered recording cuts NVR power significantly.

Environmental Conditions

Extreme cold activates built-in heaters, increasing draw by 10–20W. In hot climates, cooling fans may engage, temporarily spiking consumption.

Connectivity Type

Wired (PoE or DC): Most efficient
Wi-Fi (wireless): Constant signal transmission uses more power
Battery + Wi-Fi: Efficient at rest, but uploads consume bursts of energy

Camera Movement (PTZ Functions)

PTZ cameras idle at ~15W but peak at 30W when panning or zooming. Limit automated tours unless necessary.

How to Calculate Your Energy Cost

Estimate your system’s cost in five steps:

Add camera wattage (e.g., 4 × 7W = 28W)
Include recorder and accessories (NVR: +25W, PoE switch: +10W → Total: 63W)
Daily kWh: 63W × 24h ÷ 1,000 = 1.512 kWh/day
Monthly cost: 1.512 × 30 × $0.13 = $5.90/month
Apply 20–30% safety margin for peak loads

Use this to size your power supply correctly.

How to Reduce Power Consumption

Optimize your system with these tips:

Use motion-activated recording to cut NVR energy by up to 50%
Choose low-power models (<5W) for fixed views
Install solar-powered cameras for off-grid savings
Lower resolution/frame rate and disable AI on non-essential cameras
Use PoE switches instead of multiple wall adapters
Clean lenses and solar panels to prevent overheating
Remove redundant cameras to reduce draw and simplify management

Energy Comparison: Security Cameras vs. Household Devices

Device	Avg. Power	Monthly Cost
Security camera (avg.)	5–10W	$0.60–$2.00
LED light bulb	8–10W	$0.70–$1.20
Refrigerator	100–200W	$10–$20
Gaming console	50–100W	$5–$15
Air conditioner	1,000–3,000W	$50–$150

Bottom line: A full security system uses less power than a single refrigerator.

Frequently Asked Questions
