H.264 stream based operation
The IQA3xx camera family supports stream based configuration. Using streams does not require configuring
a specific mode of operation.
The OID values defined in Section 3.5.6,
“
H.264 RTSP stream control
”
can be used to configure the encoder,
resolution and framerate parameters for camera streams. For example, to configure two streams with the first
stream VBR H.264 encoding with a bit rate of 4000 KBits, 3 megapixel resolution and 5 frames per second
and the second stream MJPEG, QVGA resolution, 5 frames per second set the OID values:

Always configure the streams in order starting with stream 1. Set the primary stream, i.e. stream 1, to the
largest resolution and highest frame rate required by the user application. This stream will have the highest
priority. The resources available after this stream has been configured determine the configurations available
for the secondary, tertiary and quaternary streams.
To determine the number of streams that the camera supports read OID 1.17.2.18, List of available streams.
To request streams using RTSP use the following URL values.
