- Frame Rate (15 FPS, 30 FPS, etc.)
- Compression Format (H.264 or H.265)
- Recording Type (continuous or motion-triggered)
Step 2: Calculate Storage Requirement Per Camera
Using the specifications you gathered in Step 1, calculate the required storage per camera. Here’s a basic formula you can use:
Storage per Camera (GB) = (Recording Time in Hours) x (Estimated Storage Requirement per Hour)
For example, if you have a 1080p camera recording at 30 FPS, and you expect to record 24 hours of footage, the storage requirement might be calculated as follows:
- 1080p (30 FPS): Approximately 4 GB per hour
- Storage per Camera = 24 hours x 4 GB ≈ 96 GB
Step 3: Multiply By The Total Number Of Cameras
Finally, multiply the storage requirement calculated for one camera by the total number of cameras in your security system.
Total Storage Required = Storage per Camera x Number of Cameras
In this example, if you have four cameras recording at similar specifications:
- Total Storage = 96 GB x 4 cameras = 384 GB
