• 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).
