Audio & Video Settings

Video

The AXIS 250S provides the connection for a single analog camera (or other video source), on either the BNC connector or the S-Video connector. Ensure that the camera is correctly connected and powered up before attempting configuration.

•Resolution - the two video resolutions available are CIF and 4CIF. The exact resolution will depend on the type of camera being used, PAL or NTSC. See also Technical Specifications, on page 51.

•Color - Select either Color or Black & White. Black & White will provide sharper images at a lower bandwidth than Color.

•Bit rate - This setting determines how much of the available bandwidth will be used by the video stream. The bit rate is configurable from 250 to 8000 kBit/s (8 MBit/s). See also Band- width, on page 53.

•Input - Select the input the video source is connected to. The following options are available:

•BNC (composite video) - connects a standard video camera or other video source.

•Y/C (S-video)- connects an s-video camera or other video equipment.

•Source modulation - The AXIS 250S supports both of today's common video modulation stan- dards. Select the correct standard from the drop-down list.

•NTSC - delivering 525 lines of resolution at 60 half-frames per second, this is the common standard in the United States.

•PAL - the dominant standard in Europe, delivering 625 lines at 50 half-frames per second.

•Enable pre-trigger and/or Post-trigger recording - The AXIS 250S MPEG-2 Video Server is capable of recording directly before and/or after an event occurs. This is achieved by constantly buffering (and overwriting) a certain amount of the video stream into the internal memory. When the event is triggered, the memory contents are added to the actual recording.
