Pic1.Pan/Tilt Operation Timing Chart

Please note that the Preset commands sendaresponse only at the end of their executions.

The recommended minimum period of control signal communications is70ms.

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.

Pic2.Other Commands Timing Chart

Aside from Pan/Tilt, other protocols sendaresponse at the end of their executions depending on

the situation; the response time of the camera may take up to7seconds.
