Example - Scenario 1
I have a system of 4 cameras on NTSC and no audio. I have the following setup:

Normal record at 5 IPS

Schedule1 for 12 hr of recording on alarm trigger at alarm record rate 5 IPS

Schedule1 alarms are all set to Interleave mode.
How do I use the Calculate function to figure out the record time on a 160 GB hard drive,
assuming 50% (6 hr) of the Schedule1 duration is in alarm-triggered recording?
1. Normal Record Mode: Estimate HD space needed for 12 hours of normal recording.
