Roles determine the users' permission to view metadata.
Inputs
On many devices, you can attach external units to input ports on the device. Input units are typically external
sensors. You can use such external sensors, for example, for detecting if doors, windows, or gates are opened.
Input from such external input units is treated as events by the system.
You can use such events in rules. For example, you could create a rule specifying that a camera should begin
recording when an input is activated, and stop recording 30 seconds after the input is deactivated.
Outputs
On many devices, you can attach external units to output ports on the device. This allows you to
activate/deactivate lights, sirens, etc. through the system.
You can use output when creating rules. You can create rules that automatically activate or deactivate outputs,
and rules that trigger actions when the state of an output is changed.
Device groups (explained)
Grouping of devices into device groups is part of the Add Hardware wizard, but you can always modify the
groups and add more groups if needed.
You can benefit from grouping different types of devices (cameras, microphones, speakers, metadata, inputs,
and outputs) on your system:
l
Device groups help you maintain an intuitive overview of devices on your system
l
Devices can exist in several groups
l
You can create subgroups and subgroups in subgroups
l
You can specify common properties for all devices within a device group in one go
l
Device properties set via the group are not stored for the group but on the individual devices
l
When dealing with roles, you can specify common security settings for all devices within a device group
in one go
l
When dealing with rules, you can apply a rule for all devices within a device group in one go
You can add as many device groups as required, but you cannot mix different types of devices (for example
cameras and speakers) in a device group.
