Whenever I go to take a picture for a patients chart an error that reads "Failed to acquire image from that device" pops up. I know the webcam is installed correctly as I can use it just fine anywhere else but on Centricity.

Look for a file called capture.avi. Delete the file and then relaunch centricity.

Have you tried using the copy and paste function with Snipping Tool?

Essentially open the camera in the webcam native application, then use snipping tool to take a grab of the picture and paste it into CPS.

That way you do not have to use the CPS direct integration.

Are you using Centricity via a Thick Client (installed locally) or a Thin Client like Citrix? If a Thin Client like Citrix, then it is my understanding that the system has to be set up to allow a pass-through for any locally attached devices.

We experienced the same thing in our environment on both fat-client and thin-client systems. On the thin-client sessions, all you would need to do is allow host connected interfaces to take advantage of any connected devices. In this case, a Citrix session with the pass-through permissions will see the webcam on the hosts end and allow it to be used by Centricity, which bypasses this error message. It is however a completely different process on fat-client based machines. After many calls about this issue, we decided to take it upon ourselves to find a workaround, since one could not be provided to us by GE.

The first fat-client method is inadvisable, for obvious security reasons in a domain environment, since the workaround involves modifying user permissions for the fat-client machine. The method worked by giving the user local admin rights on the fat-client itself, then logging them off and logging them back on. Since it is an extremely terrible idea to give regular users admin rights just to give them the ability to take a snapshot using CPS integration, we scrapped the idea as a whole. We then gave them a secondary workaround that involves using the Logitech software that comes bundled with the webcams that wefrequently distribute to our users.

The users would open the software, snap a picture of the patient, save the file on our SAN share / mapped network drive and then browse to the file in the patient's registration. This is an extremely long and drawn out process to get something so simple in a patient's chart, but GE still has not been able to provide us with a workflow that doesn't involve modifying user privileges so that users can use the built in tool while on fat-client machines.

You might also try Chews on Straws method. That is one that we did not approach, but it seems like it would work just fine as well.

I believe we got ours to work by creating an empty file, capture.avi, in the root of C: and giving everyone Full Control to that one file to get Logitech Cams working. Just used Notepad to create the file.

We are getting the error "Error 32785: Possibly too much data for field. Retry?" when trying to save pictures from a webcam into a patient's registration. Any ideas why that would be?
