Calculating Security Camera Power Consumption
To calculate the power consumption of a security camera, you need to consider the camera’s wattage, usage patterns, and the number of hours it operates per day. Here’s a simple formula to estimate the power consumption of a security camera:
Power Consumption (Wh) = Camera Wattage (W) x Number of Hours Operated per Day
For example, if a security camera consumes 5 watts of power and operates for 24 hours a day, its daily power consumption would be:
Power Consumption (Wh) = 5 W x 24 h = 120 Wh
To calculate the monthly power consumption, multiply the daily power consumption by the number of days in the month:
Monthly Power Consumption (Wh) = Daily Power Consumption (Wh) x Number of Days in the Month
Using the same example, the monthly power consumption would be:
Monthly Power Consumption (Wh) = 120 Wh x 30 days = 3600 Wh
Converting Power Consumption to Kilowatt-Hours (kWh)
To express the power consumption in kilowatt-hours (kWh), divide the total watt-hours (Wh) by 1000:
kWh = Wh / 1000
Using the same example, the monthly power consumption in kWh would be:
kWh = 3600 Wh / 1000 = 3.6 kWh
Comparing Security Camera Power Consumption
To put the power consumption of security cameras into perspective, let’s compare it with other common household appliances:
| Appliance | Power Consumption (W) |
| — | — |
| Security Camera | 2-20 W |
| LED Light Bulb | 9-12 W |
| Smartphone Charger | 5-10 W |
| Laptop | 20-50 W |
| Refrigerator | 100-200 W |
As you can see, security cameras consume relatively low amounts of power compared to other household appliances.
