When you add an event-based rule in the Manage Rule wizard, you can select between a number of different event types. In order for you to get a good overview, events you can select are listed in groups according to whether they are:
Hardware:
Some hardware is capable of creating events themselves, for example to detect motion. You can use these as events but you must configure them on the hardware before you can use them in the system. You may only be able to use the events listed on some hardware as not all types of cameras can detect tampering or temperature changes.
Hardware - Configurable events:
Configurable events from hardware are automatically imported from device drivers. This means that they vary from hardware to hardware and are not documented here. Configurable events are not triggered until you have added them to the system and configured them on the Event tab for hardware. Some of the configurable events also require that you configure the camera (hardware) itself.
Hardware - Predefined events:
Event |
Description |
|---|---|
Communication Error (Hardware) |
Occurs when a connection to the hardware is lost. |
Communication Started (Hardware) |
Occurs when communication with the hardware is successfully established. |
Communication Stopped (Hardware) |
Occurs when communication with the hardware is successfully stopped. |
Devices - Configurable events:
Configurable events from devices are automatically imported from device drivers. This means that they vary from device to device and are not documented here. Configurable events are not triggered until you have added them to the system and configured them on the Event tab on a device.
Devices - Predefined events:
Event |
Description |
|---|---|
Bookmark Reference Requested |
Occurs when a bookmark is made in live or playback mode in the clients. Also, a requirement for using the Default record on bookmark rule. |
Communication Error (Device) |
Occurs when a connection to a device is lost, or when an attempt is made to communicate with a device, and the attempt is unsuccessful. |
Communication Started (Device) |
Occurs when communication with a device is successfully established. |
Communication Stopped (Device) |
Occurs when communication with a device is successfully stopped. |
Evidence Lock Changed |
Occurs when an evidence lock is changed for devices by a client user or via the MIP SDK. |
Evidence Locked |
Occurs when an evidence lock is created for devices by a client user or via the MIP SDK. |
Evidence Unlocked |
Occurs when an evidence lock is removed for devices by a client user or via the MIP SDK. |
Feed Overflow Started |
Feed overflow (media overflow) occurs when a recording server cannot process received data as quickly as specified in the configuration and therefore is forced to discard some recordings. If the server is healthy, feed overflow usually happens because of slow disk writes. You can resolve this either by reducing the amount of data written, or by improving the storage system's performance. Reduce the amount of written data by reducing frame rates, resolution or image quality on your cameras, but this may degrade recording quality. If you are not interested in that, instead improve your storage system's performance by installing extra drives to share the load or by installing faster disks or controllers. You can use this event to trigger actions that helps you avoid the problem, for example, to lower the recording frame rate. |
Feed Overflow Stopped |
Occurs when feed overflow (see description of the Feed Overflow Started event) ends. |
Live Client Feed Requested |
Occurs when client users request a live stream from a device. The event occurs upon the request even if the client user's request later turns out to be unsuccessful, for example because the client user does not have the rights required for viewing the requested live feed or because the feed is for some reason stopped. |
Live Client Feed Terminated |
Occurs when client users no longer request a live stream from a device. |
Manual Recording Started |
Occurs when a client user starts a recording session for a camera. The event is triggered even if the device is already recording via rule actions. |
Manual Recording Stopped |
Occurs when a client user stops a recording session for a camera. If the rule system also has started a recording session it continues recording even after the manual recording is stopped. |
Marked Data Reference Requested |
Occurs when an evidence lock is made in playback mode in the clients or via the MIP SDK. An event is created that you can use in your rules. |
Motion Started |
Occurs when the system detects motion in video received from cameras. This type of event requires that the system's motion detection is enabled for the cameras to which the event is linked. In addition to the system's motion detection, some cameras can detect motion themselves and trigger the Motion Started (HW) event, but it depends on the configuration of the camera hardware and in the system. See Hardware - Configurable events above. |
Motion Stopped |
Occurs when motion is no longer detected in received video. See also the description of the Motion Started event. This type of event requires that the system's motion detection is enabled for the cameras to which the event is linked. In addition to the system's motion detection, some cameras can detect motion themselves and trigger the Motion Stopped (HW) event, but it depends on the configuration of the camera hardware and in the system. See Hardware - Configurable events above. |
Output Activated |
Occurs when an external output port on a device is activated. This type of event requires that at least one device on your system supports output ports. |
Output Changed |
Occurs when the state of an external output port on a device is changed. This type of event requires that at least one device on your system supports output ports. |
Output Deactivated |
Occurs when an external output port on a device is deactivated. This type of event requires that at least one device on your system supports output ports. |
PTZ Manual Session Started |
Occurs when a manually operated PTZ session (as opposed to a PTZ session based on scheduled patrolling or automatically triggered by an event) is started on a camera. This type of event requires that the cameras to which the event is linked are PTZ cameras. |
PTZ Manual Session Stopped |
Occurs when a manually operated PTZ session (as opposed to a PTZ session based on scheduled patrolling or automatically triggered by an event) is stopped on a camera. This type of event requires that the cameras to which the event is linked are PTZ cameras. |
Recording Started |
Occurs whenever recording is started. There is a separate event for manual recording started. |
Recording Stopped |
Occurs whenever recording is stopped. There is a separate event for manual recording stopped. |
Settings Changed |
Occurs when settings on a device are successfully changed. |
Settings Changed Error |
Occurs when an attempt is made to change settings on a device, and the attempt is unsuccessful. |
External events - Predefined events:
Event |
Description |
|---|---|
Request Play Audio Message |
Activated when play audio messages are requested via the MIP Software Development Kit (SDK). Through the MIP SDK a third-party vendor can develop custom plug-ins (for example, integration to external access control systems or similar) for your system. |
Request Start Recording |
Activated when start recordings are requested via the MIP Software Development Kit (SDK). Through the MIP SDK a third-party vendor can develop custom plug-ins (for example, integration to external access control systems or similar) for your system. |
Request Stop Recording |
Activated when stop recordings are requested via the MIP SDK. Through the MIP SDK a third party vendor can develop custom plug-ins (for example, integration to external access control systems or similar) for your system. |
External events - Generic events:
Generic events allow you to trigger actions in the system by sending simple strings via the IP network to the system. The purpose of generic events is to allow as many external sources as possible to interact with the system.
External events - User-defined events:
A number of events custom made to suit your system may also be selectable. You can use such user-defined events for:
See User-defined events (explained) for more information.
Recording servers:
Event |
Description |
|---|---|
Archive Available |
Occurs when an archive for a recording server becomes available after having been unavailable (see Archive Unavailable). |
Archive Unavailable |
Occurs when an archive for a recording server becomes unavailable, for example if the connection to an archive located on a network drive is lost. In such cases, you cannot archive recordings. You can use the event to, for example, trigger an alarm or a notification profile so that an email notification is automatically sent to relevant people in your organization. |
Archive Not Finished |
Occurs when an archive for a recording server is not finished with the last archiving round when the next is scheduled to start. |
Database Deleting Recordings Before Set Retention Size |
Occurs when the retention time limit is reached before the database size limit. |
Database Deleting Recordings Before Set Retention Time |
Occurs when database size limit is reached before the retention time limit. |
Database Disk Full - Auto Archiving |
Occurs when a database disk is full. A database disk is considered to be full when there is less than 5GB of space is left on the disk: The oldest data in a database is always auto-archived (or deleted if no next archive is defined) when less than 5GB of space is free. |
Database Disk Full - Deleting |
Occurs when a database disk is full and less than 1GB space is free. Data is deleted even if a next archive is defined. A database always requires 250MB of free space. If this limit is reached (if data is not deleted fast enough), no more data is written to the database until enough space has been freed. The actual maximum size of your database is the number of gigabytes you specify, minus 5GB. |
Database Full - Auto Archiving |
Occurs when an archive for a recording server is full and needs to auto-archive to an archive in the storage. |
Database Repair |
Occurs if a database becomes corrupted, in which case the system automatically attempts two different database repair methods: a fast repair and a thorough repair. |
Database Storage Available |
Occurs when a storage for a recording server becomes available after having been unavailable (see Database Storage Unavailable). You can, for example, use the event to start recording if it has been stopped by a Database Storage Unavailable event. |
Database Storage Unavailable |
Occurs when a storage for a recording server becomes unavailable, for example if the connection to a storage located on a network drive is lost. In such cases, you cannot archive recordings. You can use the event to, for example, stop recording, trigger an alarm or a notification profile so an e-mail notification is automatically sent to relevant people in your organization. |
Failover Started |
Occurs when a failover recording server takes over from a recording server. See Failover recording servers (explained). |
Failover Stopped |
Occurs when a recording server becomes available again, and can take over from a failover recording server. |
