“
low
”
and
“

”
as parameters.
These modifiers can be used to specify the resolution of the H.264 stream. Note that RTSP still needs to be
used to negotiate the underlying transport protocol parameters. For example, to request a TCP based Unicast
H.264 video only stream at a resolution of 1080p use the URL:
rtsp://<camera_ip>/now.mp4?res=1080p&mm=v
To request a H.264 stream tunneled over HTTP with 2MP resolution and both audio and video use the URL:
http://<camera_ip>/rtsp/now.mp4?res=1600x1200
