EverFocus EDR810M, EDR810H, EDR410H, EDR410M instruction manual

4.SEQ (MAIN/CALL): Set the number of seconds a camera is displayed in sequence. The first number is for sequence on the Main Monitor, the second number is for sequence on Call Monitor.

5.REC QUALITY: Select an image quality for recording. There are six different qualities available. A higher image quality uses more HDD space. To change this, simply use the Jog Dial on the DVR. The approximate space needed per second is listed below:

Note: “Simple” refers to very few changes occurring during recording; “Complex” means the whole image is constantly changing. Since the compression ratio of MPEG4 fully depends on the variation and complexity of the recorded video, the table above is for reference only.
