Where the function is intended for
A rotating camera looks like full coverage, while an event can actually take place outside the frame when the lens visits another preset.

Set Dahua PTZ presets and patrol
A PTZ can see a lot, but it can only film one direction at a time at any given moment. Presets therefore must have a deliberate task.
Setting or condition
Determine which fixed points are important, whether there are other cameras for continuous overview and which movement or alarm action the PTZ should follow.
Making a conscious choice
Create designated presets for specific locations and choose a quiet patrol only where missed details are acceptable. Use a fixed camera next to the PTZ if continuous recording is necessary.
What you check afterwards
Call up each preset, check focus and limits, and after a patrol, retrieve a recording. Confirm that users know which direction the PTZ was pointing at at the time.
Frequently asked questions
Does a PTZ replace multiple fixed cameras?
Not always; a PTZ film does not capture all directions at once.
Does a preset need to have a clear name?
Yes. Names such as entrance or loading platform make operation and searching understandable.
