Estimate the hard drive storage your security system needs based on camera count, resolution, frame rate, codec, and recording duration.
Results are for planning purposes only. Actual storage may vary.
- This calculator generates values which should be used for planning purposes only.
- It is suggested to calculate camera bandwidth by CBR (Constant bit rate). Same camera settings may have different bandwidth efficiency due to varying environments.
- The actual bandwidth is an approximate reference value and may vary according to different recording environments.
