Networked VGA Grid User Guide 3-3 Fine-tune channel configuration
Increasing the number of seconds between key frames can significantly reduce your bandwidth and system
resource usage with minor impact to your video quality. A good rule of thumb is to keep the interval between 2
to 3 seconds and decrease the key frame interval as the motion increases. Try different settings and note
changes in the video quality. If your video quality is poor and jittery you may need to decrease the interval
between key frames. If you have unlimited bandwidth and system resources you can choose an option to
stream key frames only.
To adjust the key frame interval:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface .
2. Login as admin.
3. From the web interface, select a channel; the menu expands.
4. Click Stream Setup; the Stream Setup page opens.
5. Scroll to the Key frame interval drop-down menu. Choose the number of seconds before the system
streams a key frame.
Choosing Key frames only option increases bandwidth and system resource usage.
