How many days can a 500g hard disk be recorded with four cameras 24 hours a day?

On this issue, cameras are divided into ordinary cameras and high-definition cameras:

Ordinary camera

200m/h X24 = 5G g.

4 X5G=20G/ day

So the 500G disk is actually 460g, and the installation system uses 20G disk C and 10G disk D as backup. Here is e, which is 430G divided by 20=2 1 day.

In other words, an ordinary camera with 500G can record video for 20 days.

high definition camera

A camera 1~2G/ hour, calculated as 2G, 2GX24=48G, 48X4= 192G. That is to say, four a day costs 200G g g.

So the HD camera 500G can record for 2 days.

Pixels above PS: 1024x720 are HD cameras.
