If the current mode of camera parameters is set to schedule, the image configuration mode will
automatically switch between day and night according to the schedule.

Video / Audio Configuration

Set the resolution, frame rate, bitrate type, and video quality and so on subject to the actual network
condition.
Three video streams can be adjustable.
•
Resolution: Select the resolution for each stream from the drop-down options.
• Frame rate: The higher the frame rate, the video is smoother. The maximum value is 30 unless HFR is
enabled under Display Settings.
• Bitrate type: Select from CBR and VBR. If CBR is selected, no matter how much change is seen in the
video scene, the compression bitrate will remain constant. If VBR is selected, the compression bitrate
will vary according to scene changes. This can help optimize network bandwidth usage.
• Bitrate: When the bitrate mode is set to CBR, adjust the bitrate in Kbps. The higher the bitrate, the
better the image quality will be.
• Video Quality: hen bitrate type is set to VBR, adjust the video quality from the drop-down options. The
higher the image quality, the more bitrate will be required.
•
I-Frame interval: Determine how many frames are allowed between a "group of pictures". If there is not
much movement in the scene, setting the I-Frame value higher than the frame rate can result in less
bandwidth usage. If the I-Frame value is set too high, and there are frequent changes in the scene, there
is a risk of frame skipping.
• Video Compression: Select the compression for each stream from H.265, H.264, or MJPEG (MJPEG is
not available for the mainstream). When selecting H.265, make sure the client system supports this
codec. Compared to H.264, H.265 reduces the transmission bitrate under the same resolution, frame
rate and image quality.
• Profile: When selecting H.264 as the compression, select the applicable profile. Baseline, main and high
profiles are selectable.
• Send Snapshot: Select which stream will capture snapshots when events occur.
• Video encode slice split: When enabled, the camera will stream a smooth image through a low-
performance PC.
• Watermark: If enabled a watermark will be added to the recorded video. The watermark text can be
entered by the user as needed.
