System information

1-8
• Image recording from 4 cameras (VB-M40).
• Image size is 320 x 240 and image quality is 3 (data size per frame: 15.3 KB).
• Recording frame rate is 2 fps.
• Data size per second is approximately 30.6 KB (= 15.3 KB x 2 fps).
Although the actual recording file size depends on the objects recorded by each camera, this calculation assumes the
typical sizes given above.
If JPEG images from 4 cameras are recorded at 2 frames per second in continuous recording mode, the required hard disk
space is approximately 10 GB per day (= 30.6 KB x 4 cameras x 60 seconds x 60 minutes x 24 hours = 10,575,360 KB).

The actual data size may increase or decrease depending on the objects being recorded. Make sure to confirm the data size for the
actual system environment before starting operation.
