How Many Days Of HD CCTV Video Will My Hard Drive Store?

A security video recorder can support hard drives of various capacities, ranging from 500Gb to 8TB! How do you select the right HDD capacity for your particular requirements? First step is to determine days of recorded video you require stored for possible future retrieval. Next step is to perform the calculations. Head on over to our Hard Drive Usage Calculator or view the table below.

Formula:

  • Storage capacity (Gigabyte)= 3600s (per hour)x24 hours (per day)xBitrate (kbps)/8 (Bit converted to byte)/1024 (Megabytes)/1024 (Gigabytes)
  • 21GB = 3500 x 24 x 2048 / 8 / 1024 / 1024
Recording Resolution Recording channels/Number of IPC 500G 1TB 2TB 4TB
1.0 Megapixel (720p) 4 channels 6 days 12 days 24 days 48 days
8 channels 3 days 6 days 12 days 24 days
16 channels 1.5 days 3 days 6 days 12 days
2.0 Megapixel (1080p) 4 channels 3 days 6 days 12.5 days 24 days
8 channels 1.5 days 3 days 6 days 12 days
16 channels 0.74 days 1.5 days 3 days 6 days

 

IP Camera Bandwidth Calculator

IP camera bandwidth also varies with bitrate setting, the default setting value of 1080p IP camera is 4096Kb/s, so the required network bandwidth is: 4096Kb/s÷8 (1 byte = 8 bit) = 512KB/s = 4Mb/s; 4 megapixel IP camera = 8192Kb/s = 1024KB/s = 8Mb/s
