4. - 4 - - Supported devices : WJ-ND400, ND300A and ND200 - Input # of cameras, recording days, HDD capacity etc., then # of units and HDD are calculated. - The limitations to simplify the operation: * Only MPEG-4 and JPEG(4VGA) are supported. (JPEG VGA and JPEG QVGA are not supported.) * Only one parameter set is available for each camera category. (Camera Category : MPEG-4 / JPEG 4VGA(NP304/NF302) / JPEG 4VGA(NP1000)) * Schedule Setting is not available. (Only “Recording Days” and “Hours/Day” can be set.) * Event Recording is not calculated. * The bandwidth for output from NVR is not calculated. NVR Simple Calculator - Preface and features

(Refer to the figure-A) -If the required HDD in an expansion unit is only 1pc, the total # of HDDs is maintained at same # by shifting a HDD from Main unit to the expansion unit. (Refer to the figure-B) * Except ND300A/HDE300 with 1TB HDD. In this case, only 3 HDDs are installed in the main unit, then one more HDD is added. (Refer to the next calculation Rule-5.)
