Notes:
Please use this calculator as a reference only. The calculated result is not
guaranteed and the actual requirement depends on several other factors such as
light conditions, camera view properties, scene details, video quality, etc.
The calculation is based on a standard 420 lines colour camera. For High
resolution cameras, the recording days will be lower due to the higher resolution.
For PTZ cameras, the recording days will be lower due to higher frame size with
moving camera scenes when PTZ is activated.
