Why is my PTZ reaction so slow?
First thing to check is whether you have the box Enable buffering of the stream checked in the Universal Camera module settings for this camera.
If it is, you should know that it changes is the latency between an event actually occurring and you seeing it on screen. When you press the PTZ control – the camera actually moves instantly, but the picture for the stream arrives slightly later. This is a feature of buffering – it allows you to smooth out a stream at the cost of some latency.
If having slower PTZ reaction outweighs the smoothing effect of buffering, consider unchecking the box and getting rid of the buffering.
