Several key factors influence the amount of storage required for an NVR system. Understanding these variables can help you better plan and optimize your NVR System for Home Surveillance, whether it's a traditional setup or a Wireless NVR Surveillance solution.

Below, we break down the main elements that affect NVR storage needs.

Camera Resolution
Camera resolution greatly affects storage usage. Higher resolutions such as 4K produce more detailed videos but require significantly more storage. In comparison, 1080p or 720p cameras consume less storage while offering lower image quality.

Frame Rate
The frame rate, measured in frames per second (FPS), influences video smoothness and storage needs. Higher frame rates like 30 FPS provide fluid motion but require more storage. Lowering the FPS reduces storage usage while still capturing usable footage.

Compression Format
Video compression technology plays a critical role in storage efficiency. Modern codecs such as H.265 can reduce file sizes by nearly half compared to H.264, allowing longer retention periods without compromising video quality.

Number of Cameras
The total number of cameras connected to the NVR directly affects storage demand. Each camera adds to the overall data volume. It is essential to include all cameras—whether in a wired or Wireless NVR Surveillance system—when estimating storage needs.

Retention Period
The retention period refers to the duration video footage is stored before being overwritten. Longer storage periods, such as 30 days, require larger capacity than shorter ones like 7 days. Your security needs and legal requirements should guide this decision.
