Record Rate   IPS

System-Wide IPS (Example: If recording 10   cameras @ 15 ips each, select 150 for the Record Rate)

Quality (File Size) Kb  

(MRH Series: Standard = 3Kb, High = 6Kb, Very High = 8Kb)
(MR Series: Low = 2Kb, Standard = 3Kb, High = 7Kb, Very High = 21Kb)

Recording Time Day(s) Hr(s)  

The calculations listed are based on recording 24 hours per day at CIF “Standard” resolution (352x240). To calculate recording durations at 2CIF “High” (704x240) resolution, divide the total number of hours by 2. To calculate recording durations at 4CIF “Very High” (704x480) resolution (MRH series only), divide the total number of hours by 4. The maximum recording rate at specific resolution settings vary based on the model, please refer to the technical DVR specifications or the information above for details.
