Stream settings
The camera supports multiple streams with frame sizes ranging from 480 x 272 to 1920 x 1080 pixels.
• Stream 1—You can define the “Region of Interest” (viewing region) and the “Output Frame Size”
(size of the live view window)
•
Stream 2—The default frame size for Stream 2 is set to the 1280 x 720
• Stream 3—The default frame size for Stream 3 is set to the 640 x 360
•
Stream 4—The default frame size for Stream 3 is set to the 1920 x 1080
Click Viewing Window to open the viewing region settings page. On this page, you can configure the
Region of Interest and the Output Frame Size for a video stream. For example, you can crop only a
portion of the image that is of your interest, and thus save the bandwidth needed to transmit the video
stream.
To set up those settings for a stream, follow these steps:
1. Select a stream for which you want to set up the viewing region.
1.
Select a Region of Interest from the drop-down list. The floating frame, the same as the one in the
Global View window on the home page, will resize accordingly. If you want to set up a customized
viewing region, you can also resize and drag the floating frame to a desired position with your
mouse.
2. Choose a proper Output Frame Size from the drop-down list according to the size of your monitoring
device.
Note All the items in the “Region of Interest” should not be larger than the “Output Frame Size” (current
maximum resolution).
• The parameters of the multiple streams are as follows:
Region of Interest Output frame size
Stream 1 1920 x 1080 ~ 640 x 480
(Selectable) 1920 x 1080 ~ 640 x 480
