How to Calculate the Storage Capacity

Calculating the storage capacity needed for your home security system involves a few straightforward steps:

1. Step 1: Determine the Frame Size: The frame size is the amount of data generated for each frame of video. It is typically measured in kilobytes (KB) or megabytes (MB). The frame size depends on factors like resolution, compression settings, and frame rate. Check your camera specifications or consult the manufacturer’s documentation to find the frame size for your system.
2. Step 2: Calculate the Bitrate: The bitrate is the amount of data recorded per second by the camera. It is calculated by multiplying the frame size by the frame rate. For example, if the frame size is 200KB and the frame rate is 15 frames per second, the bitrate will be 3,000KB or 3MB per second.
3. Step 3: Determine the Recording Duration: Decide how long you want to retain the recorded footage. Let’s say you want to keep two weeks of footage, which is equivalent to 14 days.
4. Step 4: Calculate the Storage Capacity: Multiply the bitrate by the number of seconds in a day (24 hours x 60 minutes x 60 seconds) to get the daily storage requirement. Multiply the daily storage requirement by the number of days you want to retain the footage. For example, if the daily storage requirement is 3MB and you want to store footage for 14 days, the total storage capacity needed would be 42MB.
5. Step 5: Account for Additional Factors: Consider factors like system updates, firmware upgrades, and unexpected increases in recording duration or camera count. Allocate additional storage space to accommodate these factors. It’s recommended to have a buffer of at least 20% of the calculated storage capacity for contingencies.
