NOTES:
•

Setting the image quality to LOW may improve latency. If you are experiencing issues with latency, 
try using one of the LOW settings.

•

If your computer is on a different subnet than the camera to which you wish to connect, you must 
use a unicast setting. Multicast video streams are not allowed to pass through subnets.
