CCTV storage calculator formula. CCTV storage calculator formula is based on the bandwidth of camera. The recording capacity is mainly up to the record resolution, record stream and bitrate. Different image quality parameters decide different disk capacity occupation in equal times. The bigger the record resolution, record stream and record bitrate are, the more disk capacity is taken up in equal times. You can easily calculate how much capacity you required for a specific amount of time.  before learning CCTV storage calculator formula, first, understand the what is bitrate.

What is bitrate?

In simple words, You can say, bitrate is a flow of data. When an image is processed then it takes the signal from a processor in the form data. The CCTV setup which gives you high quality of an image, have the high quality of processor and flow more quantity of data in comparison to others system. the higher the bit rate of a video, the higher the video quality.

The CCTV storage calculator formula of recording capacity is shown as below.

CCTV storage calculator formula

Recording Capacity(MB) = Bitrate(Kbps) ÷1024 ÷8 × 3600 × Recording hours per day ×Record Storage Days × channel numbers.

3600 means record for an hour(1TB=1024GB,1GB=1024MB,1MB=1024KB,1Byte=8bit).

For your understanding, we define a table

The table below shows the recording capacity requirements for record storage in 30 days.

For instance, there is a 32CH NVR recording 24 hours per day and the record stores for 30 days. The NVR adopts dual stream recording. The mainstream is 4096Kbps and the substream is 1024Kbps, then the total recording capacity is 49.45TB (39.56TB + 9.89TB). Considering the format loss of the disk is about 10%, the required disk capacity will be 55TB (49.45TB ÷(1-10%)). This table is mainly for IP camera setup but using same formula you can calculate the storage capacity for all kind of camera.
