go1984 > Basic setup > Recording > Calculating memory requirements

One of the most frequently asked questions is: how much hard-drive space will the recordings use? There's no simple answer to the question because many factors play a role. These include:

•The number of cameras (AK)

•The number of frames per second (FPS)

•The image size (KB)

•The amount of compression

•Whether recording is permanent or motion-triggered

In order to get a rough idea of memory requirements in the case of permanent recording, use the following rule of thumb: You can usually assume the image size (KB) to be about 25-30 kilobytes.

AK * FPS * KB = kilobytes/second

This will give you the approximate number of kilobytes needed per second recorded. Multiplying by 3600 gives you an idea of the number of kilobytes needed per hour.

Please note that go1984 uses intelligent ring storage management to contribute significantly to efficient memory management. In many cases, it makes sense in any case to use motion-triggered recording, which reduces memory requirements substantially.
