4.7 Limitations
Before using VideoSecurity Online, there are some limitations you have to
understand so that you can appropriately use this application.
• While using Webcams or CCDs, the high temperature and luminance
sensibility often cause distorted CCDs of the images, which might
result in erroneous detection.
• If the features (e.g. color, luminance) of the object are much similar
with that of the background, the object might not be detected.
• The Webcams or CCD cannot successfully capture the object if the
object moves too fast.
• VideoSecurity Online can only process UYVY, YUY2 and I420 video
format.
• Due to the limitation of Video Mixing Renderer in Win2000,
VideoSecurity3500 doesn’t support User Dened Motion Detection
and Tracing features in Win2000.
• VideoSecurity doesn’t support 256 color, we suggest that users run
the program under 16-bit color environment or above.
Known Issues
• If you want to connect two USB devices to the system, we
recommend that you connect them to USB ports of different USB port
modules. Do not use two USB ports in the same USB port module, for
example, using port 1 and 2 at the same time.
