This type of cameras is used in case the video flow should be taken from Acumen boards.
In order to select and configure the video capture board Acumen as the data source, you should perform consistently the following steps (see fig. Channel settings. Selection of video capture board Acumen as the source of video):
- select source type - board Acumen;
- select the board type;
- select the channel;
- configure the video flow transmission parameters.
When Acumen board is selected as the source of video, video flow transmission parameters can be set for it.
Board model - this option allows you to specify the model used by the board. For today, Overseer Traffic supports the following types of boards Acumen: Ai-SC367, Ai-SC387, Ai-SC347, Ai-SC165, Ai-SC185, Ai-SC145, Ai-SC333, Ai-BOX, Ai-SC310.
Channel - each board Acumen has from 4 to 16 channels for connecting video cameras (the number of channels depends on the model Acumen). It complies with the number of connectors on the adapter to connect the cameras (DB25-16BNC), to which the given camera is connected.
Video Standard. Overseer supports two standards of video flow transmission PAL_B and NTSC_M. Settings of the video format and resolution should be set according to the used video source and the required image in the channel.
FPS. Determines the number of frames transmitted per second. The valid values are 25,12.5, 6.25, 3.125
Resolution. This field is to select the necessary resolution .Raising the resolution in direct ratio affects the quality of recognition, and inversely affects the velocity of data transmission. The valid resolutions depend on the type of Acumen board’s model.
The selection of the option "deinterlace" applies the filter required to eliminate the effect of interlacing to the selected video. In case of interlacing, which arises when combining the previous half-frame with the current one (eg. the even lines - from the current half-frame and odd - from the previous one) in the video of interlaced format, the edges of lenses have the form of comb (see fig. Channel settings. Frame with interlacing'Italic text) which significantly affects the recognition quality.
