23-6 Camera Handler Release Notes

rotating 270 degree in the NVR.This is because the NVR is trying to provide a

uniform presentation for all supported cameras.

• Corridor mode support: QuickTime issue after Image Rotated: Quick Time

should b

e able to display the 'corridor' image. However the user needs to restart

QuickTime by navigating to a different tab and restarting the live view. It is

because the actual resolution has changed from 1920x1080 and it becomes

1080x1920 after rotation. QuickTime does not have the capability like Victor to

auto-adjust to this resolution change.

• When the user adds a camera to the NVR the BitRate control values become

unchecked in the camera

GUI. This does not affect actual bitrate - what is

requested from the NVR is still received. This also happens when changing Bit

Rate Control on the NVR GUI.

i625 & i825 MJPEG Usage Consideration

MJPEG video does not use any temporal compression but uses spatial compression. This makes

its bandwidth requirements much greater than H.264.

General recommendation:

• Maximum Possible Quality Setting: 100

• Recommended Maximum Setting: 90

• Recommended High Quality Setting: 75

• Recommended Medium Quality Setting: 55

In addition to the above, MJPEG at high resolution

and frame rate will use a very large amount of

bandwidth. For high resolution, the following is recommended:
