Goal

Setup a streaming video solution that small locations can use easily for broadcasting small events, security video or other uses. Because those locations may not have a static IP, route video traffic from your main static IP (on your openvpn server) over a tunnel to the remote location.

Overview

The remote location will require internet access. They will be provided with the following equipment:

Minibox style x86 computer
Monitor/Keyboard/Mouse
Axis P1344 camera w/ POE injector OR Axis Q-7401 capture box
network (2 blue cables are straight through, red is crossover) + power cables

Setup instructions

Axis camera

Power up camera.
Connect to web interface of the camera.
Set admin password (example root:test123).
Setup -> Video Stream -> Audio -> Check Enable Audio checkbox.
Setup -> Video Stream -> Image -> Resolution = 640x480.

Axis capture box

Power up box.
Connect to web interface of the camera.
Set admin password (example root:test123).

End User Instructions

Please verify that all of the following components shipped properly:

Router
Monitor
Camera
Camera power injector
2 x 50' blue network cables
1 x 14' red network cable
2 x 6' black power cables
1 x AC power brick
1 x monitor video cable
1 x keyboard
1 x mouse

Place router in desired location. It should be placed on a flat, stable surface.
Place monitor nearby to the router.
Use one 6' power cord, connect to the monitor and power the monitor on.
Connect the monitor video cable from the monitor "RGB" port to the corresponding port on the router.
Place camera power injector in desired location.
Connect red network cable from the "Data In" jack on the power injector to the router port labelled "Camera".
Connect Internet connection to the router port labelled "Internet" using a blue network cable.
Connect keyboard and mouse to USB ports on the rear of the router.
Plug the AC power brick into the router and then an available power outlet. The router will turn itself on automatically.
Wait for a 3 toned beep from the router and the desktop environment to appear. (Note: Mozilla Firefox will open with the error message "Well, this is embarassing". This is normal.).
Connect blue network cable from the camera to the "Data & Power Out" jack on the power injector.
Once the light on the top of the camera turns green, click "Start New Session" in Firefox. A video window should appear after a brief delay.
Adjust the focus and zoom of the camera manually using the dials on the front of the camera.
To test the stream on the remote location end, open VLC on a computer with Internet connectivity, then run File -> Open Network Stream and connect to http://public.ip.addr.ess:8080.
