Camera monitor the recorded file 1 hour how much G ah?
Analog surveillance camera video files per hour about 220M, digital surveillance camera video files per hour about 900M.
Monitor video 24 hours per channel per day Recording space size calculation formula:
3600 seconds (per hour) * 24 hours (per day) * Rate (128kbps-8Mbps) / 8 (conversion of bytes and bits) / 1024 (converted to M) / 1024 (converted to G) ≈21G (bit rate is To 2Mbps for the column)
With the hard disk capacity divided by the size of the daily video file and then divided by the number of cameras is the number of days to save the video
