MPEG-4 JPEG 4VGA (NP304/NF302)

NVR Simple Calculator - Parameter Window

MPEG-4 Setting : -For the reference, estimated frame rate is shown beside max. bit rate. The value will be changed automatically based on the setting of Resolution and Quality.

JPEG 4VGA (NP304/NF302) Setting : -For the reference, estimated frame rate and data size per image are shown beside Quality setting. -REC ips is limited to the estimated frame rate automatically. -Estimated total bandwidth for the cameras is shown.

JPEG 4VGA (NP1000) Setting : -Similar setting to JPEG 4VGA (NP304/NF302).

JPEG 4VGA (NP1000) REC Option

REC Option Setting : - Audio and VMD Info. can be selected. This setting is applied to all cameras.

- 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.

1. # of main units are calculated on the following conditions:

2. Cameras are assigned to NVR as evenly as possible.

3. Optimize the camera assignment to NVR so that the # of expansion units can be minimized.

4. Storage calculation in RAID5/RAID6 Mode

-If the required HDD is only 1pc, one more HDD is added to satisfy the above condition [2]. (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.)

5. “2TB Limitation” is calculated in ND300A RAID5 mode.

In case of WJ-ND300A with 1TB HDD or more in RAID5 mode,the # of HDD in a unit will be not 4 but 3. (including parity)

“2TB Limitation” ... The maximum net capacity is limited to 2TB in RAID5 mode.e.g.　 Even though you install 4x 1TB HDD to ND300A,　 you cannot record 3TB but 2TB.
