1.2.Communication Timing Chart

Please note that the Preset commands send a response only at the end of their executions.
The recommended minimum period of control signal communications is 70ms.
For the Pan/Tilt operation, setting up the communication period shorter than the recommendation
may cause protocol loss or extend the response time of the camera.
Aside from Pan/Tilt, other protocols send a response at the end of their executions depending on
the situation; the response time of the camera may take up to 7 seconds.
