This calculator can give you an estimate of how much storage space you would need to accommodate your body-worn camera footage, based on the number of body-worn cameras you have and how often your team uses them.
Note: In addition to the video bitrate, there is a small overhead associated with the audio and container format - typically around 70kbit/s.
Additionally, this calculator does not factor incident retention into account
So a video bitrate of 6.30 Mbits/s will lead to an overall bitrate of 6.37 Mbits/s.
| The average number of hours of footage collected per day will be: | 5.71 | hours per unit | 17.14 | hours total |
|---|---|---|---|---|
| If collected footage is retained for 28 days, the stored footage will be: | 160.00 | hours per unit | 480.00 | hours total |
| At 6.37 Mbits/s the storage required for one hour of footage will be: | 2.87 | gigabytes per unit | 8.60 | gigabytes total |
| So the total for 480.00 hours will be: | 1.38 Terabytes | |||
Terms: In this calculator we use the terms 'Megabyte', 'Gigabyte' and 'Terabyte' to represent 'one million bytes', 'one billion bytes' and 'one trillion bytes' respectively, as these are the definitions used by hard drive vendors.
Additional requirements: This calculation accounts for body-worn camera footage only. Additional requirements include space for burned DVD images and the database structure; however, this will generally amount to 20Gb or less.
