This page explains all terms, words and abbreviation Mirasys is using. Please let us know via our support if you feel there other terms we should explain here.
A CCTV camera that provides the video stream analogue. Typically via COAX cable.
Alarms in our VMS are configured in system manager and can be assigned to user profiles. Alarms have a trigger, action and an calendar where they can be activated based on hour.
This functionality can be triggered manually in the Spotter application or scheduled in the system configuration. It is the fastest way to get data out of the system. The granularity is only in full hour.
This SDK allows to open and process Mirasys archives and requires a signed NDA to be used.
IP camera with own address and user interface for configuration.
We use this term for video formats like H.264/265, JPEG/MJPEG, MxPEG, ...
All adjustments to the system behaviour on server side or via the System Manager.
Converter from analogue camera stream to digital. These devices have an own IP address.
We use the term "Driver" exclusive for connectors to cameras.
Digital Video Management System. Old term for VMS.
Service name of the recoding server.
Converts digital video to analogue (video) signals. Old term. Not used in pure digital processing.
End of Live of a product version
We call an event any data, input or situation in our VMS which we can transform into an alarm. There are certainly many event's in our software which are not used for triggering alarms.
This functionality of the Spotter application provides the possibility to save video and audio data into files for any time period.
This function is granting an automatic switch from a production server to a spare (=failover) server. The switch will start when the slave server is not reachable for a configured time period. By default this threshold time is 10 minutes to avoid the process to start on temporary network problems. After a failover situation the systems have to be manually restored to the initial configuration.
Gateway is an optional service that can be installed to grant users access via web browser, mobile applications or for Gateway SDK integrations.
This is one of the integration possibilities to access all data inside the VMS. Documentation of the Gateway SDK requires a signed NDA. To enable a specific Gateway SDK integration the VMS license needs to contain a license connector.
Most common used video codec format to compress video data.
This technology is used for maser servers to grant an automatic switch within milliseconds from the production master server to a master server in standby mode. This function is typically provided by Hyper-V or VMware system.
Every VMS server (master or slave) has an own license which provides features to this one server. Example: Amount of channels, integration connectors, special plugins, ...
Securing the availability of the master server is essential different from a slave server failover. We provide this kind of functionality via operating system like MS Hyper-V (cluster) or VMware to avoid any down-time. See also high availability.
Central server with typically no recording functionality. This server is managing alarms, user access, profiles and system configuration.
This SDK allows to export data from a VMS via command line and requires a signed NDA to be used.
We separate into two groups.
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication. Multicast requires a layer 2 network switch configuration with multicast support.
Other than with Multicast the multi streaming is providing multiple individual streams from a device or server to the client or server.
All active and passive network components to enable the application to communicate. See also OSI 7-Layer model.
Network Video Recorder. Old term for VMS
This is the term for developing the software code. Not to confuse with configuration of the system.
All integrations which require an additional installation on the VMS server to communicate with a 3rd party system or device. Typically the messages are received in a UDD text channel from the proxy service.
Research and development unit at Mirasys.
See slave server.
Active network component to control, filter and direct network traffic. Typically Layer-2 or 3.
See Gateway SDK.
A software service of our software running on a Windows PC.
This is the recording server which is added to a master server.
Service and Maintenance Agreement. For detail content ask you sales representative.
Service name of the master server. This service is installed on every system but is only required on the master server for system configuration, alarm handling or user/profile management.
Spotter is the main Windows application to access the system as a user. Find more details in the Spotter User Guide for your version.
This functionality of the Spotter application allows to export of data with comments to provide in a story telling format
A stream is the data send by a device or system to a receiver. We typically use this term for video streams.
Most cameras allow to configure in the camera a stream profile to easy manage different stream properties.
This is a configuration where several master servers are connected to an higher level management server.
Active network component without control, filter and other advanced features. Typically Layer-1.
System Manager is the Windows application to configure the installation. This application is installed on every VMS server by default. In multi server installations only the System Manager of the Master server should be used to configure elements.
Training and Documentation unit at Mirasys.
Receiving point for text messages in the VMS.
This platform which is hosting all online documentation and training.
The Universal Data Driver is an extension for the text channel to receive, interpret and filter incoming text messages to use specific data to trigger events and alarms. The text channel is configured via an XMP configuration file. For more details see the UDD guide.
Video Content Analysis is the AI model based image processing to describe a video footage in text form. Example: bounding box of a moving object, speed, size, classification, colour, direction, etc.
Service name of the Watch Dog service. This service is installed on every system to monitor and restart the other services and report hardware problems.
