To enable the updating of video images in Microsoft Internet Explorer, set your browser

Image too dark or too light.

Check the video image settings. See the online help on Video and Image Settings.

 

Missing images in uploads.

This can occur when trying to use a larger image buffer than is actually available. Try

 

 

lowering the frame rate or the upload period.

 

Slow image update.

Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame

 

 

rates, etc, will reduce the performance of the camera.

 

Poor performance.

Poor performance may be caused by e.g. heavy network traffic, multiple users accessing

 

 

the unit, low performance clients, use of features such as Motion Detection, Event han-

 

 

dling, Image rotation other than 180 degrees.

 

Image gradually gets darker or lighter.

When using the camera in locations lit by fluorescent lighting, check in the advanced

 

 

image settings that the Exposure control is set to Flicker-free.

 

Image loses focus often.

Disable the DC-Iris lens in the settings for Video & Image > Advanced. Focus the cam-

 

 

era following the instructions on page 9, and then enable the DC-Iris lens.

 

Images only shown in black & white.

Check the color level setting.

 

 

Check the setting for the IR cut filter. Images are shown in color only when this filter is

 

 

enabled, i.e. when set to yes or auto.

 

Blurred images.

Refocus the camera. Check in the Video & Image > Advanced - Camera Settings that

 

 

DC-Iris is set to Enabled. If the images are still blurred adjust the metal ring until the

 

 

image is sharp, see Removing and attaching the lens, on page 60.

 

Rolling dark bands or flickering in

Try adjusting the Flicker-free exposure setting under advanced image settings. Note

that the 'Hold Current'/Manual setting may cause unwanted effects.

Video/image problems - MPEG-4

 

 

 

 

 

Lower frame rate than expected.

Check with the administrator that there is enough bandwidth available. Check also the

 

 

settings for bit rate control, in the Video & Image > Advanced > MPEG-4settings.

 

 

Using an inappropriate video object type can also affect the frame rate. See the online

 

 

help for more information.

 

 

Check in the AMC control panel applet (MPEG-4 tab) that video processing is not set to

 

 

Decode only I frames.

 

 

Lower the image resolution.

 

 

Reduce the number of applications running on the client computer.
