Electricity costs for a CCTV system can vary depending on several factors, such as the number of cameras, resolution, type (Analog or IP), whether motion detection is active, and the local electricity rates in your area.
In general, CCTV cameras have varying power requirements based on their specifications. Cameras with higher resolutions or additional features might consume more power. You also need to consider the storage device (such as a DVR or NVR), which also requires electricity.
Steps to Calculate CCTV Electricity Usage Costs!
- Check Camera Specifications: Look at the documentation to find the power consumption of each camera, usually listed in Watts (W) or Volt-Amperes (VA).
- Number of Cameras: Count the total number of cameras in your system.
- Total Power: Multiply the power consumption of one camera by the total number of cameras.
- Storage Device: Add the power consumption of your DVR or NVR to the total.
- Operational Time: Determine how many hours a day the system runs (e.g., 24 hours).
- Local Electricity Rate: Check your cost per kilowatt-hour (kWh). You can find this on the official PLN website.
- Calculate the Cost: Multiply the total power (in kW) by the operational hours and the electricity rate to get the daily, monthly, or annual estimate.
Simulation of CCTV Electricity Cost Calculation
For example, if your home electricity is 1,300 VA with a rate of Rp 1,444.70 /kWh. You use 1 IP Camera (12W), an NVR (24W), and a PoE Switch (65W).
- Total Power: $12W + 24W + 65W = 101W$
- Convert to kWh: $101W \div 1,000 = 0.101 \text{ kWh}$
- Daily Cost (24 hours):
- $$0.101 \text{ kWh} \times 24 \text{ hours} \times \text{Rp 1,444.70} = \textbf{Rp 3,501.95}$$
It's less than Rp 4,000 per day. Quite cheap, isn't it?
Note: This is only a simulation; the actual power of your devices may vary.
Remember that this is a rough estimate. Energy price fluctuations and camera efficiency can affect the actual cost. Also, consider additional costs like maintenance and software when planning your CCTV budget.
