Video / Audio Configuration - Speco O4P25X2 User Manual

Set full time schedule for common, day or night mode and specified time schedule for day and night. Choose "Timing" in the
drop-down box of schedule as shown below.
Drag " " icons to set the time of day and night. Blue means day time and blank means night time. If the current mode of camera
parameters is set to "Timing", the image configuration mode will automatically switch between day and night according to the
schedule.

5.2.2 Video / Audio Configuration

Go to ImageVideo / Audio interface as shown below. In this interface, set the resolution, frame rate, bitrate type, video quality
and so on subject to the actual network condition.
Three video streams can be adjustable.
Resolution: The size of image.
Frame rate: The higher the frame rate, the video is smoother.
Bitrate type: CBR and VBR are optional. Bitrate is related to image quality. CBR means that no matter how much change is seen in
the video scene, the compression bitrate will be kept constant. VBR means that the compression bitrate will be adjusted according to
scene changes. For example, for scenes that do not have much movement, the bitrate will be kept at a lower value. This can help
optimize the network bandwidth usage.
Bitrate: it can be adjusted when the mode is set to CBR. The higher the bitrate, the better the image quality will be.
Video Quality: It can be adjusted when the mode is set to VBR. The higher the image quality, the more bitrate will be required.
I Frame interval: It determines how many frames are allowed between a "group of pictures". When a new scene begins in a video,
until that scene ends, the entire group of frames (or pictures) can be considered as a group of pictures. If there is not much
movement in the scene, setting the value higher than the frame rate is fine, potentially resulting in less bandwidth usage. However, if
the value is set too high, and there is a high frequency of movement in the video, there is a risk of frame skipping.
Video Compression: MJPEG, H264 or H265can be optional. If H.265 is chosen, make sure the client system is able to decode H.265.
Compared to H.264, H.265 reduces the transmission bitrate under the same resolution, frame rate and image quality.
Profile: For H.264. Baseline, main and high profiles are selectable.
Send Snapshot: Set the snapshot stream.
Video encode slice split: If this function is enabled, smooth image can be gotten even though using the low-performance PC.
Watermark: When playing back the local recorded video in the search interface, the watermark can be displayed. To enable it, check
the watermark box and enter the watermark text.
