An event manager is an essential video management system (VMS) component. It allows you to configure rules for performing specific actions when predefined triggers are met.
The actions include sending notifications, playing alarms, triggering recordings, or adjusting camera settings to capture better event footage.
In Banalytics, you can create any number of rules for any component.
Click the + button next to an Event manager sub-menu under the Banalytics server.
Click the New Rule button on the Event Manager page. You can create several rules without creating a new event manager. It allows you to group the rules by meaning.

Description
Default
Restart on failure
Required
Restart mode upon catching an error:
Stop on failure - not restarted until triggered manually.
Immediately - tries to restart automatically immediately after catching an error.
10 sec - tries to restart automatically with a 10-seconds delay after catching an error.
30 sec - tries to restart automatically with a 30-seconds delay after catching an error.
1 min - tries to restart automatically with a 1-minute delay after catching an error.
Default to 10 sec

Name of the rule or a group of rules of similar nature.

An event source is a component that generates events that trigger some actions. By carefully managing event sources, you can ensure that the event manager can effectively detect and respond to security events as they occur. An event source may be a particular component or task of the Banalytics server. A rule for a camera may be configured to trigger an alarm sound when motion is detected. The motion detection task is the event source here.
An event source type is a group of sources, such as all ONVIF cameras. The ONVIF camera event source type ensures that the same action is performed upon receiving an event from any Onvif camera. Configuring a rule for all ONVIF cameras does not prevent you from configuring a specific rule for a particular camera as an event source.
Action can be triggered not just by a component but also by another event. An event type is a group of events belonging to different components. There are not many such events in Banalytics. You can specify the Motion detection event type to perform the same action upon receiving a trigger from any camera motion detection is configured for.
You can set up an action that will be performed on the triggering event. You can also set the time when the rule should be applied. Tick the Continuous flag to set up periods, or leave the flag empty to set up the rule for a particular time (precisely at 5 o'clock, for example).
Several examples
Several examples
The following configuration will trigger action upon motion detection on any camera configured for a Banalytics server.
The following configuration will trigger action upon motion detection on the particular camera configured for a Banalytics server.
The following configuration will trigger action upon motion detection on the USB home camera. It's the same as the previous one. Specifying event or event source types in the same rule is unnecessary when choosing individual sources.
This configuration will never trigger an action, as the source and type do not correlate.
This configuration will play the signal.wav audio file every day at 6:00 and 18:00. Note that the action will be performed without a trigger, as none is configured.
This configuration will trigger an alarm upon motion detection on any camera from 19:00 to 9:00. This is applicable for monitoring in an office during non-working hours.
This configuration doesn't make sense, as triggering an alarm upon motion detection is assumed only once the motion is detected right at 6:00 or 18:00, which is a low probability.
