Fujinon Lens Connection To Camera
Does anyone know of a device I can add that would
connect inbetween the Fujinon Len connector and the input in the camera. Looking for a device that would allow starting and stopping recording of the camera from about 20 feet away...? |

There is a remote port on the bottom of the lens handle. This is where you would plug in a remote start/stop and/or zoom.

The team I work with used to all work in electronics manufacturing, so there may be interest in producing some add-ons if they're marketable. |

This is all pretty much standardized already, see our sponsor VariZoom:
http://www.varizoom.com/controlsindex.html#fujinon All of the Fuji lens controllers listed on that page will have a rec start / rec pause button. VariZoom also sells a variety of extension cables as well, in ten, twenty and fifty foot lengths: http://www.varizoom.com/accessoriesindex.html#cables Hope this helps, |

The JVC Fujinon controller is HZ-ZS13U - if you Google it, you'll find it for some $600-700.

HZ-ZS13U Looks Great,,,but one question...
So, The Lens that comes with the HD-100U Camera has some flexable options. JVC never made a big deal about that in advertising its features.
My Question: Can I get a splitter made and have one device control three cameras? |

You could buy a long 8-pin Fujinon extension cable and then create a simple momentary push-button on one end for VTR start/stop. It would be simple.

From my experience from other projects, particular with these switches you get a lot of make-brake contacts during closing or opening, which would trigger or stop the recordings randomly between the camera's. Also connecting the common ground pins together through the remote connection you are suggesting looks right indeed. But adding video monitors to the component output will introduce ground loops between the grounding of the video/audio connections and the ground pin of the remote resulting in hum in the audio and scrolling bars on the video output in many cases. Worsed case with a bad monitor or connecting/disconnecting video cables, it can also damage the camera as it will surge the current through the two ground connections of the camera. At the moment (in my spare time) I'm making a device to avoid these issues and to trigger multiple camera's with a buffered and isolated trigger signal using inexpensive ethernetcables. |

I just tested my trigger theory with a couple of leads plugged into the remote port and it works beautifully. I even tried make intermittent partial connections and the lens/camera seem to be smart enough to only require a simple momentary connection. The lens circuitry must have a debouncer built in.
I had my dealer looking into the Fuji 8-pin connector part and JVC Canada has a few in stock, but they are $51 a piece. I'm going to order a few and build a 3 camera remote. I need one myself (for live concert shoots,) but I will build one for Rob too if he wants. I'm thinking of creating a simple Fuji 8-pin to ethernet adapter so that readily available lengths of ethernet cable can be used to connect the cameras to the control box. (as Marc suggested earlier.) I've also decided to use three separate SPST push switches so that each camera can be controlled individually (if needed) and then create a simple hinged "button" that will depress all three switches simultaneously. There are also pins for the RET button, so I may add an additional three buttons for RET functionality. I'll take some photos when I get the thing built.

Hi Tim,
Make sure if you use the Ethernet cable to use one of the twisted pairs. Let me know how far you can go reliable with the cable with no active components. Marc Colemont |

Someone please make a 3 camera VTR controler and sell me one

Make it, test it, start selling it. It seems pretty easy to get on JVC's approved 3rd party company links for this camera. |
