When it comes to home CCTV storage options, there are several factors to consider, including energy consumption, reliability, cost, and ease of use. Here are some options:

  1. Local NVR: A local NVR (network video recorder) is a standalone device that is designed to record and store footage from your home CCTV cameras. It is a good option if you want to keep your footage on-premises and have complete control over your data. Local NVRs generally consume less energy than running a PC server and can be set up to automatically turn off when not in use. However, you will need to ensure that the device has sufficient storage capacity for your needs.
  2. PC Server: A PC server can also be used as an NVR for home CCTV. However, a PC server will typically consume more energy than a dedicated NVR device, as it is designed for a wide range of tasks and may require more powerful hardware. Additionally, maintaining and securing a PC server can be more complex than using a standalone NVR device.
  3. Cloud Storage: Cloud storage is an option that allows you to store your CCTV footage remotely on a server owned by a third-party provider. It can be a good option if you want to access your footage from anywhere, and it generally requires minimal energy consumption. However, it may not be the most cost-effective option, and you will need to ensure that the provider you choose has appropriate security measures in place to protect your data.

In summary, a dedicated NVR device is generally the most energy-efficient and straightforward option for home CCTV storage. However, if you require remote access to your footage, cloud storage may be a better option. A PC server can be used as an NVR, but it is generally less energy-efficient than a standalone NVR device.
