The Mobile Client allows you to set arming mode of a partition, and control the zones. You can set arming mode for a specific zone, set zone parameters, link a camera to a zone, etc.
Partition, which is an independent control system of a security control panel, allows you to batch arm/disarm all zones in it. If the security control panel has two partitions, you have two independent systems for arming or disarming.
Zone is a basic concept in the security control panel system. It refers to a protection area in the system, and is regarded as the maximum recognizable unit to distinguish the alarm event.
For more information about partition and zone, see the user manual of the security control panel.
