Why this is lower than the number you will see elsewhere

Almost every published answer to this question multiplies the rating on the label by the hours the appliance is switched on. For a security camera that gives 44 kWh a year, or $8.03.

Continuous. Night vision illuminators push the draw to the top of the range after dark.

Nameplate × hours — the usual answer44 kWh$8.03
What it actually draws44 kWh$8.03

The arithmetic, step by step

Nothing here is hidden, so you can check it or change it. Working in the order the formula runs:

  1. 5 W — what it draws while it is actually drawing. This is the rating on the plate.
  2. × 100% — the share of its in-service time it is really pulling that. Continuous. Night vision illuminators push the draw to the top of the range after dark.
    That gives 5 W averaged across the hours it is on.
  3. × 24 hours a day × 365 days — One wired camera running continuously.
    5 × 24 × 365 ÷ 1,000 = 44 kWh a year.
  4. × 18.34¢ — the US average residential rate for June 2026.
    44 kWh × 18.34¢ = $8.03 a year.

Change any assumption in the calculator above and every figure on this page moves with it. The two that matter most are your rate, which varies 4× across the country, and the hours — the duty cycle is a property of the appliance, but the hours are a property of you.

How sensitive is that number?

A single figure invites more confidence than it deserves. Here is the same appliance under assumptions either side of the default, so you can see how much of the answer is the appliance and how much is the guess about how you use it.

Everything else held at the default. The spread here is the honest error bar on the headline figure.

The thing worth knowing

Individually trivial, but people install six or eight of them plus a recorder. Count the system, not the camera, and add the NVR, which is a small always-on computer in its own right.

What it costs in your state

The appliance is the same everywhere; the rate is not. Running this security camera costs $23 a year in Hawaii and $5.74 in Nevada — a difference of 4×.

Questions

How much electricity does a security camera use?
About 44 kWh a year on the assumptions above — one wired camera running continuously. That works out to an average draw of 5 W over the hours it is in service, against a rated 5 W.
Is it expensive to run a security camera?
At the US average residential rate of 18.34¢ per kWh it costs about $8.03 a year, or $0.67 a month. The same appliance costs about $5.74 a year in Nevada and $23 in Hawaii, because the rate matters more than the appliance.
Why is your figure lower than other sites?
Because 5 W is what the appliance draws while it is actually drawing, not the average over the time it is switched on. Continuous. Night vision illuminators push the draw to the top of the range after dark. Multiplying the rating by the hours gives 44 kWh a year, which is 1× the real figure.
What is the cheapest way to run a security camera?
Nothing worth cutting. Include it so the ‘other' slice of your bill reconciles.
