Network Cameras: Required Disk Space Calculator

Network Cameras: Required Disk Space Calculator

July 2014

Canon has produced an online and downloadable Required Disk Space Calculator for its range of high-quality Network Cameras which allows users to simulate bandwidth and disk space requirements for recording or live streaming video captured with a camera.

The calculator operates with a number of variables including the number of cameras being used, continuous or event recording, audio requirements, video compression method and resolution, video quality and frame rate and time period – and then gives a result for bandwidth and required disk space.

To use the Canon Required Disk Space Calculator for Network Cameras please click here.

Alternatively you can download the Required Disk Space Calculator by clicking here.

Please ensure that you have read and understood the following notes before using this software:

Selecting hard drives based on the calculated results

The values calculated by this software are only to be used as a guide. The actual amount of data may fluctuate greatly according to such factors as the recording subjects and recording environment.

In addition to video and audio, a system data area is also required for the operating system and the recording software. When preparing the hard drives for the storage server, please provide ample spare disk space.

Notes for users of the Canon Network Video Recorder RM Series

RM Series storage servers regard free disk space falling below the following value as the disk space warning value level, and they are designed to automatically delete data starting from the old data.

(Number of connected cameras + 1) x 64MB

Please note that the results calculated by this software for the recordable period do not take this specification into account.

Usage Notes and Precautions

  • This tool calculates data sizes in weeks. As a result, Total Recording Data Capacity and Recordable period are displayed in weeks.
  • The selected model and video compression method affect the options available under other settings.
  • This software requires settings (video quality, size, etc.) that differ according to the time for recording, even with a single camera. Create settings for each time slot and calculate the total amount of data from the values for those amounts. You cannot create settings that cross over dates. To configure settings that cross over dates, create settings split into night (0:00 to 8:00), day (8:00 to 18:00) and night (18:00 to 24:00).
  • This tool can save estimation results. Up to 20 projects can be saved.
  • It is being calculated by 1TB = 1024GB in this tool.
  • If it’s necessary to have a print of simulation result, please take a screenshot and then print it.
  • Tool specifications and other details are subject to change without prior notification.
