Twain Capture

Twain capture

Capture an image through a Twain device installed on your computer, and send it.

Twain is technology that is included in software that accompanies many devices such as scanners and web cameras. With it, you can transfer the image from an external device to your computer.

If your Twain device is a video camera, you can send video images. The images are captured as frames from your video device at timed intervals and sent.

To send Twain capture screenshots:

Right-click the hotCam button. From the menu, select a Twain device.
The menu lists all Twain devices installed on your computer. If you have no devices, you see no list. If you previously installed Twain devices but currently do not have the hardware attached to your computer, they still display in the list.
Click the hotCam button. It opens the software application for the Twain device you selected.
Use the device software application to capture the image you want to send.
Use the device software to send the captured image. It is sent through hotComm to the hotComm and IM-Live peers in the session.

On each peer's computer, the captured image displays in a hotCam window. A copy of the image is saved automatically in each peer's hotComm/UPLOADS folder.

Twain video

Note: If you are using hotComm version 1.01.004c or higher, use Webcam instead of hotCam for video images.

To send video captures:

Right-click the hotCam button. From the menu, select the name of your video device.
Note: The hotCam list includes supported video devices that are listed in your Windows Control Panel under Scanners and Cameras.

Click the hotCam button. This opens the hotCam Video Preview window and starts sending the timed video captures. This window shows you:

Item	Example
Capture Device Selected	Sony MOTION EYE Video
Capture Type	Still Capture or Video Capture
Video Properties	Control and Format
Snap Video	Still Collaborative Timed(5s)
Status	Session 1 - Live Video Preview - 320x240 - 100%

To set the interval for timed screenshots and video captures, use the hotCam Interval option in Preferences. The interval is in seconds.

Note: Timed hotCam screenshot and video capture updates skip slower modem peers until the next update cycle.

On each peer's computer, the video capture displays in a hotCam window. Copies of timed captures are not saved.
