Camera install in Mechanical Room viewing Zeks Air Dryer

Gerardo, Richard, Erik, Dave:

Over the holiday break we need to remotely view the operation of the Zeks Eclipse air dryer skid in the mechanical room to ensure no moisture gets into the LVEA chambers.

I initially setup a fisheye camera (a repurposed gate-cam), which gave a good view of the panel's LEDs and the mechanical gauges, but lacked the resolution to view the LCD display screen to see the Dew Point signal.

I then installed an Axis 214PTZ camera, which was able to zoom into the LCD display and read the values.

So we are now running both cameras side-by-side. 

sw-mech-aux was configured to have both ports 13 and 14 on the VID-LAN (10.106.0/24).

I ran two 60-foot cat5e ethernet cables from the vacuum rack (where the switch is located), over to the front of the Zeks skid, using the overhead mezzanine railing to provide a temporary "cable tray". 

Camera name/ip ethernet connection
fish-eye (POE) wincam (10.106.0.243/24) long run to POE injector on top of vac rack, short run to switch port14
PZT cam mechcam (10.106.0.244) direct to switch port13

Because the Axis camera is AC powered, we ran an extension cable from the vac rack to the base of the skid, passing it under the stairs to prevent it being a trip hazard.

Next to do:

1) fish-eye cam does not seem to be streaming, I have to hit reload on my web browser to refresh the image.

2) start software to capture these images every minute and post them to the CDS web page
