• Vivotek encoders do not support PTZ on Victor Client.

• There is a camera limitation on the video stream performance, if all 8 channels

are being used the combined max FPS should be around 20FS. When the

limitation is reached, the web client of the VS8801 shows "Note: Frame rates are

not guaranteed when all red-marked streams are used." within "Overview"

section of "Audio and video" page.

• The encoder has a limitation that changing one channel's audio codec will lead

to all other channels' audio codec changed as well.

• Interlace is not supported on the NVR.

• Brightness, Contrast, Sharpness, and Saturation will always be shown as 0 in

the NVR, even after users apply non-zero values to them via NVR. This is

caused by a camera limitation it is recommended that the user does not change

these values on the NVR as errors can be caused. User should change these

settings via the camera web client.
