QHY5III Series

 

05 Use BroadCast Video Streaming 

BroadCast video steaming is a special function that QHY5III series cameras support. It can send the 
video image to multiple target software via QHYCCD BroadCast video driver. For example, you can 
use  the  SharpCap  software  to  control  QHY5III  series  cameras  and  at  the  same  time  the  video 
appearing on the SharpCap will be sent to any of software that support the WDM camera, like the 
HandyAvi, Adobe video encoder, online chat software etc. This function is very useful for the video 
live broadcast applications. 
 
1. Install the 

BroadCast Driver

 

 
2. Connect camera to your PC and start SharpCap 
 
3. Turn on “Enable Live Broadcast” at the bottom of Camera Control panel in SharpCap as shown 
below. 

 

 
4. Select “QHYCCD camera (WDM)” as your webcam in the software you are using. The camera 
used in the following example is QHY5III290.
