Storage Considerations
- Alberto Brunoni (Unlicensed)
The optimal amount of storage required for recordings depends on the number of cameras, codecs, Frames per Second (FPS), resolution of the images and the percentage of pixel change.
For example: A 1.3 Megapixel camera set at 10 FPS configured to stream video at 1.5 Mbits/sec.; if it is recording motion 50% of the time, then we can estimate that we need 7GB/day of storage for that specific camera.
To estimate your requirements, use the VI Storage and Bandwidth Calculator.
Video Insight supports all the storage that Windows can address. In addition to the size of the storage, it's necessary to confirm the storage system can handle the amount of video otherwise video can be lost when the storage is overloaded.
To calculate the maximum storage throughput, it is assumed that all cameras will write simultaneously and add up all camera bit rates. Because most storage systems refer to maximum simultaneous write speeds in megabytes (MB), divide the total camera traffic by 8 to convert it to MB.
For example: The IP Server has 100 cameras streaming at 3 Mbits/sec. (or a total of 300 Mbits) and it is expected that they are to record 50% of the time; therefore, the storage system must be able to write 37.5 MB/sec. at its maximum.
Video Insight has developed a Storage Speed Test application to confirm an IP Server’s capability. To download it, go to DownloadVI.com/Tools and, under the Utilities section, click on Hard Drive Speed Test.

Camera storage options
Record Always | Requires significantly more storage space because video is constantly recorded. |
Motion Only | Requires less storage space than Record Always because video is recorded only when motion occurs in the camera’s field of view. |
Schedule | Allows both Record Always and Motion Only within specified schedules. |
