The USB Web camera is the cheapest solution but it must be located near the PC, requires the installation of WDM or BDA drivers, that are not always 100% reliable, requires additional software for displaying or streaming the captured images, and while streaming, the images are delayed 3 - 10 seconds compared to reality.
For the IP camera the higher price is the main disadvantage, but it is independent on the PC and the distance is also not the issue, the supplied software or the images provided via the network can be easily integrated in the PROMOTIC system, it is more reliable, and suffers minimal image delays.
In the panel of PROMOTIC application, "General" is selected. In the ProgID configurator, the corresponding ActiveX is selected and its interface is used in order to connect to the camera's IP address (tested with Air Live WL-5400CAM).
In the panel of PROMOTIC application, "General" is selected. In the ActiveX items list the Windows media player is selected and its properties menu is used for setting the camera's URL address (the url entry).
Another option is to create own HTML page containing the Windows media player plugin with the connection to a specific address. This page can be then offered via the PmWebDir object and also displayed by the PmReport object.
