How Many Watts Does a CCTV Camera Use?
ZacharyWilliamSecurity Camera Power Guide
A practical wattage, energy-cost, and backup-runtime guide for CCTV cameras, PoE cameras, NVRs, DVRs, routers, and small security systems.
Last updated: May 28, 2026
Most CCTV or IP security cameras use about 4 to 12 watts each during normal use. A basic indoor camera may use only 2 to 5 watts, a typical PoE outdoor camera with night vision often lands around 6 to 12 watts, and a PTZ camera can use 15 to 30 watts or more when motors, infrared LEDs, heaters, or wipers are active.
For a real security setup, do not size power from the camera alone. Add the NVR or DVR, hard drive, PoE switch or injector, modem/router, and any monitor you plan to keep on. A simple 4-camera PoE system often runs around 45 to 70 watts total. An 8-camera system often falls around 80 to 130 watts, depending on camera model, night vision, recording settings, and network gear.
Typical CCTV Camera Wattage by Camera Type
The safest rule is to check your camera label or datasheet first. If you do not have it, use the table below for planning. These ranges reflect common security-camera categories, but exact wattage changes with resolution, infrared night vision, AI processing, pan-tilt motors, outdoor heating, and whether the camera is powered by 12V DC or PoE.
| Camera type | Typical running watts | When it may draw more | Best planning number | Source / reference |
|---|---|---|---|---|
| Basic indoor Wi-Fi or wired camera | 2–5W | Two-way audio, motion spotlight, poor Wi-Fi signal, continuous upload | 5W per camera | Security camera wattage overview |
| Standard 1080p / 2MP PoE camera | 4–8W | IR LEDs on at night, high frame rate, onboard analytics | 8W per camera | Reolink PoE power table |
| 4MP / 4K outdoor dome or bullet camera with IR | 6–12W | Long-range night vision, spotlight mode, AI detection, colder weather | 10–12W per camera | Hikvision 4MP dome datasheet |
| Dual-lens, color-night-vision, or AI camera | 10–15W | Dual sensors, onboard AI, spotlights, siren, active deterrence | 15W per camera | Reolink model power ranges |
| PTZ camera | 15–30W | Pan/tilt movement, zoom, long IR, heater, wiper, de-icing features | 25–30W for common PTZ; more for heated PTZ | Hanwha PTZ power specs |
| Doorbell camera | 5–10W | Chime, recording, two-way talk, poor Wi-Fi, cold weather | 10W per camera | Doorbell camera range |
The real answer changes at night
A camera that looks like a 5W device in the daytime can draw closer to 8–12W after sunset because infrared LEDs, spotlights, or color night vision turn on. For backup planning, size the system for the night load, not the sunny daytime number.
Camera-Only Watts vs Complete Security-System Watts
Many articles answer only the camera wattage question. That is useful, but it is not enough if you want to keep your security system running during a power outage. The NVR, DVR, router, modem, PoE switch, and hard drive can use more power than one or two cameras.
| Setup | Camera load | Recorder / network load | Estimated total watts | Practical note |
|---|---|---|---|---|
| 1 standalone indoor camera | 3–5W | Router may add 8–15W if cloud access is needed | 5–20W | Good fit for small DC backup, but keep the Wi-Fi router powered too. |
| 1 outdoor PoE camera + injector | 6–12W | Injector or switch loss adds overhead | 10–18W | Measure at the wall if the injector has its own AC adapter. |
| 4-camera PoE home system | 24–48W | NVR + HDD + router often add 20–30W | 45–70W | Common whole-home security size for outages. |
| 8-camera PoE system | 48–96W | NVR + HDD + router often add 25–35W | 80–130W | Use a larger battery if you need overnight runtime. |
| 16-camera small-business system | 96–192W | NVR + multiple HDDs + network gear can add 35–60W | 140–250W | Camera model mix matters more than channel count alone. |
| PTZ-heavy perimeter system | Varies widely | PoE+ or PoE++ power budget may be required | Plan from datasheets | Do not estimate; PTZ motors, heaters, and IR can change the design. |
For recorder power, an 8-channel NVR can be under 10–15W without hard drives and PoE output, while larger NVRs can be 30–50W or more without counting the cameras. If the NVR includes built-in PoE, the camera power may be counted through the NVR power adapter instead of separately at a switch.
How to Calculate CCTV Camera Power Use
You only need three simple formulas. Use watts for instant load, watt-hours for battery runtime, and kilowatt-hours for electricity cost.
Watts = Volts × AmpsDaily kWh = Total watts × 24 ÷ 1000Backup runtime hours = Battery Wh × 0.90 ÷ Total watts
Example 1: a 12V CCTV camera label says 0.5A
12 volts × 0.5 amps = 6 watts. If it runs 24 hours a day, it uses 6W × 24 ÷ 1000 = 0.144 kWh per day.
Example 2: four 8W PoE cameras plus an NVR
Four cameras at 8W each = 32W. Add a 15W NVR, a 5W hard drive estimate, and a 10W router. Total estimated load is about 62W. This is the number you use for backup runtime, not just the camera total.
Why this article uses 90% battery efficiency
When a portable power station powers AC adapters, NVRs, PoE injectors, or routers, some energy is lost in conversion. For UDPOWER runtime examples in this article, usable energy is calculated at 90% of rated capacity for practical planning.
How Much Does It Cost to Run CCTV Cameras 24/7?
Security cameras are low-watt devices, but they run all day. The monthly cost is still usually modest for small systems. The table below uses an example electricity rate of $0.18 per kWh, close to recent U.S. residential average pricing. Your actual bill may be higher or lower depending on your state and utility plan.
| Setup | Total watts | Daily energy | 30-day energy | Estimated monthly cost at $0.18/kWh |
|---|---|---|---|---|
| Single 6W camera | 6W | 0.14 kWh | 4.32 kWh | $0.78 |
| Single camera + Wi-Fi router | 18W | 0.43 kWh | 12.96 kWh | $2.33 |
| 4-camera system + NVR | 50W | 1.20 kWh | 36.00 kWh | $6.48 |
| 8-camera system + NVR + router | 100W | 2.40 kWh | 72.00 kWh | $12.96 |
| 16-camera system + larger recorder | 175W | 4.20 kWh | 126.00 kWh | $22.68 |
To make the number more accurate, replace $0.18 with the price listed on your electric bill. The U.S. Energy Information Administration publishes state-level and sector-level electricity price data, but local utility rates can vary sharply.
How Long Can a Portable Power Station Run CCTV Cameras?
For outage planning, start with the total system load. Include the cameras, NVR or DVR, router, modem, PoE switch, and any required AC power adapters. Then divide usable battery energy by total watts.
Runtime = Power station capacity × 0.90 ÷ total system watts| Security load | Estimated total watts | UDPOWER C600 596Wh | UDPOWER S1200 1,190Wh | UDPOWER S2400 2,083Wh |
|---|---|---|---|---|
| One 6W camera only | 6W | About 89 hours | About 179 hours | About 312 hours |
| Camera + router | 18W | About 30 hours | About 60 hours | About 104 hours |
| 4-camera system + NVR | 50W | About 11 hours | About 21 hours | About 37 hours |
| 4-camera PoE system + router | 65W | About 8 hours | About 16 hours | About 29 hours |
| 8-camera system + NVR + router | 100W | About 5 hours | About 11 hours | About 19 hours |
| 16-camera system + larger recorder | 175W | About 3 hours | About 6 hours | About 11 hours |
Before you size backup power, check these five things
- Night load: IR, spotlights, and color night vision can raise watts after sunset.
- PoE source: A PoE NVR, PoE switch, or injector may add conversion loss.
- Network gear: Remote viewing needs a modem/router, not just the cameras.
- Monitor: A monitor can add 20–40W if left on continuously.
- Low-load behavior: Very small loads may trigger energy-saving shutoff on some battery systems; use the correct output mode for continuous security devices.

Solar note for security backup
If your cameras are used in an off-grid cabin, barn, jobsite, RV, or remote gate location, pair the power station with solar panels based on the daily watt-hour load. For example, a 50W security setup uses about 1.2 kWh per day. Solar can help extend runtime, but actual recharge depends on panel size, sun hours, shade, weather, and panel angle.

PoE can be confusing because the wattage printed on a switch port is not always the camera’s actual power draw. A camera may draw 6 to 10 watts in normal use, while the PoE port reserves a higher power class to guarantee stable operation.
| PoE type | Common standard | Power available at port | Typical CCTV use | Planning advice |
|---|---|---|---|---|
| PoE | IEEE 802.3af | Up to 15.4W per port | Most fixed dome, turret, and bullet cameras | Check that total switch PoE budget covers all cameras. |
| PoE+ | IEEE 802.3at | Up to 30W per port | PTZ cameras, stronger IR, some AI or multi-sensor cameras | Use PoE+ when the datasheet asks for it, even if average watts look lower. |
| PoE++ | IEEE 802.3bt | Higher-power Type 3 / Type 4 classes | High-power PTZ, heaters, long-range IR, specialty cameras | Do not guess. Match the camera datasheet and injector/switch class. |
A common mistake is buying an 8-port PoE switch because each port looks strong enough, then missing the total PoE budget. For example, eight cameras drawing 10W each need at least 80W of camera power before switch losses. If the switch has only a 60W PoE budget, some cameras may reboot at night when IR turns on.
How to Reduce CCTV Power Use Without Weakening Security
The goal is not to starve the camera of power. The goal is to cut waste while keeping the areas that matter covered.
- Use the right night-vision mode. Infrared is usually more efficient than keeping bright white spotlights on all night.
- Lower frame rate where it makes sense. A driveway or hallway may not need the same frame rate as a cash register or loading dock.
- Use motion alerts without disabling recording that matters. Event-based recording can reduce storage and sometimes processing load, but critical areas may still need continuous recording.
- Turn off the monitor when not in use. The display can use more power than several cameras.
- Use efficient network gear. A small router and a right-sized PoE switch are usually better for backup than a large always-on networking stack.
- Keep cables and connectors in good condition. Poor cable runs can cause voltage drop, unstable PoE negotiation, and camera reboots.
- Separate essential and nonessential loads. During an outage, keep cameras, recorder, and router online first; leave screens and extra lights off unless needed.
UDPOWER low-load tip
Very low-power devices can sometimes fall below a portable power station’s auto-shutoff threshold. For continuous camera, router, or sensor loads, use the output mode recommended for long-running low-power devices. UDPOWER’s low-power auto-shutoff guide explains why Normal Mode is often better for continuous small loads than ECO Mode.

Use these scenarios as starting points, then adjust based on your exact camera labels and recorder specs.
| Use case | Likely load | Recommended direction | Why |
|---|---|---|---|
| Single Wi-Fi camera watching a porch | 5–20W including router | C600 or larger | Small load, long runtime, easy indoor placement. |
| Home 4-camera PoE system | 45–70W | S1200 | Better all-night backup margin for NVR, cameras, and router. |
| 8-camera system with NVR and remote viewing | 80–130W | S2400 | More capacity for overnight runtime and network gear. |
| Off-grid cabin with cameras, router, and Starlink Mini | Often 70–150W depending on network load | S2400 + solar | Security cameras rarely work alone in remote setups; internet gear changes the power budget. |
| Small business with many cameras | 140W+ | Measure actual load, then size above it | Recorder, HDD count, PoE switch, PTZ cameras, and monitor habits vary too much to guess. |
FAQ: CCTV Camera Watts and Backup Power
How many watts does one CCTV camera use?
Most CCTV or IP security cameras use about 4 to 12 watts. Basic indoor cameras may use 2 to 5 watts, while outdoor PoE cameras with infrared night vision often use 6 to 12 watts. PTZ cameras can use much more.
Does a CCTV camera use a lot of electricity?
No. One 6W camera running 24/7 uses about 4.32 kWh per month. At $0.18 per kWh, that is about $0.78 per month. A complete multi-camera system costs more because the NVR, router, and PoE equipment also run 24/7.
How many watts does a 4-camera CCTV system use?
A typical 4-camera PoE system often uses about 45 to 70 watts total after adding the NVR, hard drive, router, and PoE overhead. If the cameras have strong night vision or spotlights, plan closer to the high end.
How many watts does an 8-camera CCTV system use?
An 8-camera system commonly falls around 80 to 130 watts with an NVR and router included. PTZ cameras, multiple hard drives, and always-on monitors can raise the total.
Do PoE cameras use more power than 12V cameras?
Not automatically. PoE is a power delivery method, not a guarantee of higher consumption. A PoE camera may draw only 6 to 10 watts, but the switch or injector must still have enough per-port and total PoE budget to support it, especially when infrared turns on.
Why does my camera system use more power at night?
Night vision is the main reason. Infrared LEDs, spotlights, color night vision, heaters, and PTZ movement can increase load after dark. For backup planning, use the nighttime wattage or the datasheet’s maximum power value.
Can a portable power station run CCTV cameras?
Yes. A portable power station can run cameras, NVRs, routers, and PoE injectors as long as total wattage is within the output rating and the battery capacity matches your desired runtime. For example, a 50W small NVR system can run about 21 hours on a UDPOWER S1200 using a 90% efficiency estimate.
Should I power the NVR or each camera during an outage?
For PoE systems, the simplest approach is usually to power the NVR or PoE switch that feeds the cameras, plus the router if remote viewing is needed. For separate 12V cameras, you may need to power each camera adapter and the recorder.
Should I include the monitor in my backup power calculation?
Only if the monitor must stay on. Many homes and small businesses can turn the screen off during an outage and keep only the cameras, recorder, and network gear powered. This can save 20 to 40 watts or more.
What is the easiest way to know my exact CCTV wattage?
Use a plug-in watt meter at the wall for the whole system. Let the system run during the day and at night, then record the higher number. That measurement is usually more useful than estimating each camera separately.
