15.9. Recording Rate
The recording rate indicates the number of images to be recorded per second and is expressed by the unit IPS (Image Per Second). In the Digital Video Recorder, the total recording rate is the sum of each camera’s recording rate and recordings can be made for up to 120 IPS in normal mode and for up to 60 IPS in mirror recording mode. The maximum recording rate that can be set per camera is 60 IPS.
The recording rate to be set on the menu screen is displayed, rounded up. The following table shows the relationship of menu screen display vs. actual recording rate.
Menu screen display | Actual recording rate |
| Menu screen display | Actual recording rate |
60 | 60.000000 |
| 1/2 | 0.468750 |
30 | 30.000000 |
