Calculate storage needs for home security cameras based on resolution, frame rate, and recording duration
Home security cameras are essential for monitoring and securing your property. However, the footage they capture requires storage. The amount of storage needed depends on several factors including the camera's resolution, frame rate, number of cameras, and how long you want to store the footage.
The resolution of the camera affects the quality and size of the video files. Higher resolutions like 4K produce larger files compared to lower resolutions like 720p. The frame rate, measured in frames per second (fps), also impacts storage needs. A higher frame rate results in smoother video but requires more storage.
To calculate the required storage, we consider the bitrate of the camera, which is influenced by its resolution and frame rate. The total storage needed is then calculated based on the number of cameras, the recording duration, and the bitrate.
| Resolution | Frame Rate (fps) | Bitrate (Mbps) | Storage per Hour per Camera (GB) |
|---|---|---|---|
| 720p | 30 | 2 | 0.9 |
| 1080p | 30 | 4 | 1.8 |
| 4K | 30 | 15 | 6.75 |
