To calculate the hard drive space on a Helix NVR, you can use the provided capacity calculator.
To use the tool, install the application and click click Add Streaming. Select the number of channels, compression, resolution, frame rate, and bit rate of the cameras being used. Click on the Recording Day tab and select the storage capacity, as well as the recording plan being used (24 hours per day will be default. Click the icon to calculate the max number of days for the specified capacity.
Calculating HDD space Manually.
Here is the formula for calculating hard drive space for a NVR manually:
Hard drive space = (number of cameras * resolution * frame rate * recording days) / 8
Note: If you have 4 cameras connected to your NVR, each with a resolution of 1080p and a frame rate of 30fps, and you want to record video for 7 days, you will need a hard drive with a capacity of at least:
(4 cameras * 1080p * 30fps * 7 days) / 8 = 10368000 bytes
This is equivalent to 10.368 GB of hard drive space.
Here are some additional tips for calculating hard drive space for your NVR:
- If you have a lot of cameras or you want to record video for a long period of time, you will need a hard drive with a larger capacity.
- If you have cameras with different resolutions or frame rates, you will need to calculate the hard drive space for each camera individually and then add up the total.
