CagePro Upgrade 2.0

To make make CagePro Cage for the GoPro3 more usable, i am in the process of adding Video Out and Audio In. As you can see, the modification is straightforward and easy to do with the right tools.

I am only faced with some issues (which you might have an idea of):

  1. Sound is filled with hum noise when the Monitor is connected. If i remove the coax cable from Video-In, everything is fine.
  2. Lifting GND does not help, neither caps, capacitors or resistors (tried everything).
  3. It is definitely not related with the power input of the CagePro. I already ruled that out.
  4. It’s definitely coming in over the coax. Either it’s floating ground or some weird issue.

Good thing is:

  1. Video Out works perfectly with BNC.
  2. Why i use BNC ? Gives the possibility to use T-Connectors and distribute the signal to a video transmitter plus the Monitor out.


  1. Find a good and doable solution for Audio In. Either i use 3.5mm plugs or XLR, but the space is limited inside the current cage.

And the best: It’s available for rent starting 15.January 2014
