We are trying to set up for video conferencing. We currently have a ceiling mounted projector. I'm concerned about how or if we can place a camera over the screen. Will the projector "washout" the camera so that the participants will not be visible? Anyone have experience with this that can give some advice?

Thanks!

It is done, but very difficult to use a projector with video conferencing. Mostly this is because you typically need lights down lower for best case projection, and lights as ABSOLUTELY bright as possible for best case VTC. This means that the two are at opposite ends from each other for the final goal you are trying to achieve.

These days, it is far more common to do a dual 52" to 70" LCD screen setup with a VTC camera located between the two screens for VTC. This is what I would call a 'typical' VTC setup.

The light from the projector will NOT impact the camera typically unless you have the projector in the view of the camera.

But, ABOVE the screen is a horrendous location for the camera. The camera should be placed at eye level so you aren't looking down on the bald heads of the older guys and down the blouses of the women.

This is what I do for my job - design and install VTC systems. A typical job for me runs around $100,000, which may be a lot more than you are looking to spend, but the rules shouldn't change. Get the camera down at eye level, get the light UP in the room, and if the projector doesn't work with that, then figure something else out. Most people use VTC because it is a solution to an expensive travel issue within their business and opens business doorways, so spending an appropriate amount of money on a rock solid setup, will pay off in the long term. I'm not saying it needs to be $100K, but it needs to be appropriate, and the current projector setup may not be appropriate.

Why would you like to place camera on top of Projector screen? Instead you cam connect an HDMI cable from projector to your laptop and conduct the video conference using various tools like webex, R-HUB HD Video conferencing servers, gotomeeting etc.

In a group meeting, you don't use a camera built into a laptop, but a proper camera in the room, mounted to the wall. So, it may be next to a screen, above a screen, or below a screen at the front of the room.

Singular conferencing, as you are describing, is certainly becoming much more popular, but still has issues reaching into the conference room where large groups get together.

So, a in-room computer would be connected to the projector via HDMI, but the camera itself these days often uses a USB extender to connect to the in-room computer and room microphones are also connected to the computer using USB.

But, keep in mind this original post was from 8 years ago when Skype For Business (or Teams), Zoom Rooms, and Webex, were far less common tools for video conferencing.
