Camera Streaming

Getting Started

Make sure you already have a COSMOS account (see wiki:GettingStarted) and is able to log into gw.cosmos-lab.org:

ssh COSMOS_USER@gw.cosmos-lab.org

Here, COSMOS_USER is your COSMOS username.

The following cameras can be accessed within the COSMOS network.

Name	Location	Orientation	IP	Type
cam1-md12-logia-ams.bed.cosmos-lab.org	Mudd 12F Logia	Amsterdam Ave North	10.110.12.4	​AXIS Q3628-VE Dome Camera
cam2-md12-botwinik-120.bed.cosmos-lab.org	Mudd 12F Botwinik Lab	120th St East	10.110.12.5	​AXIS Q1808-LE Bullet Camera

RTSP Access Within COSMOS

If you have logged into the COSMOS network (e.g. on GW or any other node), you can access the RTSP stream using tools like FFmpeg under the URL:

rtsp://public:cosmos@CAMERA_NAME_OR_IP/axis-media/media.amp

Replace the CAMERA_NAME_OR_IP with the name or the IP address of the desired camera, found in the table above.

For example, the command below records a 10s video from the 12F-logia camera in 30 FPS:

ffmpeg -nostdin -rtsp_transport udp -i rtsp://public:cosmos@cam1-md12-logia-ams.bed.cosmos-lab.org/axis-media/media.amp -r 30 -vcodec copy -an -t 10 output.mp4

Camera Access Outside of COSMOS

You can also access the camera web interface from the outside:

1. Choose an used port on your machine, e.g. 8080.

2. Forward the camera interface at port 80 to your local 8080 port via SSH (replace the CAMERA_NAME_OR_IP and COSMOS_USERNAME):

ssh -L 8080:CAMERA_NAME_OR_IP:80 COSMOS_USERNAME@gw.cosmos-lab.org

3. From your browser, go to localhost:8080.

4. When prompted, enter username public and password cosmos.
