Q5: What may be the cause for lower FPS (frame per second)
performance on my VS80?
VS80 can achieve its proper 80 fps speed with Mpeg4 codec. You may
experience performance in the 60 fps range if the camera is using H.264
codec because H.264 uses more decoding resources. Therefore, your actual
performance may vary if you use a combination of MPEG4 and H.264 cameras.
Q6: Why does VS80 display Unsupported Profile on the camera
screen?
When H.264 camera uses profile other than Baseline profile, or when MPEG4
camera uses profile other than Simple profile, VS80 won't be able to process the
different profile levels for each video codec and causes this warning message.
The solution is to enter the IP camera's portal page and adjust the codec profile
with the recommended profile settings above.
Q7: When facing long video delays, how do I reduce the latency?
If video latency is too long, try decreasing the image quality or frame rate from
Surveillance Station or Camera portal to reduce the system workload.
Q8: Why do Live View and Event Playback aspect ratio look
different?
This is caused by the LCD monitor or TV which you are using. To resolve this
issue, go to the Main menu for your LCD/TV, use the Auto Adjust function and
your screen aspect ratio will return to normal.
