We moved the top wood block over the edge of the ledge to get the far left of the choir seats so we could see the open area where musicians played instruments. We get the whole choir and then some. Yet, we can zoom in on just the director's head and shoulders. I guess I will include a full swing of the camera zoomed back and forward.

The computer we use is not dedicated to webcasting and is used as the desk computer in the FHC. So it takes an nearly and hour to setup and get running. Spring is here and the yard keeps calling me and I succumb.

Installation images

I installed it myself with help pulling cables and mounting. FM at the time didn't have the skills but they could now that I went through installing new 881 routers and access points with them.
Here are some images.

I was wondering how you ran control to the camera. Then after looking more closely, it appears you have an IR emitter pointed to the IR sensor on the rear of the camera. Is this correct? How did you extend the IR signal (what device and cost)?

IR emitter not used

We tried to use the IR emitter but it only worked half way down the hall. It was a wireless that converted tp IR. Pulled a cat5e cable from camera to sat cabinet but not working yet. the RS422 to serial/USB port converter didn't work. Still looking for one that will work. There is a separate thread on the subject.

Using IR remote that came with camera. Just preset positions and give to someone that can see the monitor set in the corner of overflow area. Some training is required but is easy to use.

It's a common practice to use CAT5 cable to extend the distance to IR emitters. And if the runs are more that 100' or so, we typically use more conductors (tie grn/wht to brn/wht, etc.) to send the signal farther.

Hope this helps.

I finally figured out how to get an RS422 to USB converter to work. It took forever and was really frustrating, but it works. The long story short is that you have to wire it wrong...you can't follow the wiring diagrams/instructions that come with the converter.

I'm not sure who originally posted this image, but it got me going. Notice that between the converter and camera, you wire positive to negative throughout (R- to T+, R+ to T-, T- to R+, and T+ to R-). If you daisy chain cameras, you wire things the correct way (R+ to T+, R- to T- etc.). I had purchased three different converters and could not get any of them to work. Once I wired things this way, everything worked!

I highly recommend trying a program called D70 Commander that was written by a fellow forum member: http://www.cwshop.com/LDSSoftware/. It allows you to configure preset camera angles, overlay basic text, etc. I'm going to post a new thread that outlines everything I recently went through to get things working.

Fantastic! I tried for weeks to get RS-422 to work with software. I tried at least 4 different adapters, cards, etc. and several software programs and never could. It was very frustrating.

Thanks for your perseverance!

Also, the wiring diagram you included is GREAT. Easy to understand how to make things work and where the wires go. I really appreciate this!

The real champion is lpuster who wrote the software I used and sent the wiring diagram from another thread he found!

Hi, I just have one question. What is the ideal distance between the cam and pulpit. I'm afraid to mount it to far from the pulpit to get a good picture.

What the EVI-D70 picture looks like at 60'

Postby michaelfish » Sat Sep 08, 2012 4:00 pm

We mounted cameras at the rear of the overflow area just in front of the cultural hall.

Here is a sample of what you can expect using a Sony EVI-D70 camera if mounted 60' from the pulput. The cameras on the sides are about 75' from the pulpit.

The EVI-D70 zoom ratio is 18x without digital zoom (which deteriorates the picture substancially). We have found we don't even zoom all the way in, so at 60' to 75', it still looks great!
