Ways to cut the cost

  • 1

    Prefer wired models over battery-recharge designs

    Battery designs waste ~15% in charging losses

  • 2

    Replace old doorbell transformers — some draw 3-5W continuous

    Saves 15-40 kWh/year

  • 3

    Disable continuous recording, use motion-triggered only

    Saves camera processing watts
