This article describes the terms of LinkVisual.
Term | Description |
|---|---|
instance | You can manage resources such as products, devices, and rules in IoT Platform instances. The following two types of instances are supported:
|
instance of the video type | IoT Platform instances of the video type belong to Enterprise Edition instances and provide the services to process audio and video data. You can connect IP cameras and network video recorders (NVRs) to IoT Platform instances of the video type. |
edge machine of the V series (LE-V) | LE-V provides high-performance computing modules to support the algorithms of facial recognition, human shape recognition, human trajectory tracking, detection of area intrusion or occupation, and reverse image search. |
IP camera | An IP camera is a type of digital video camera. |
NVR | An network video recorder (NVR) is a device that records videos. |
PTZ control | Pan-tilt-zoom (PTZ) control indicates moving the camera in different directions to obtain a whole picture and zooming in for further details. |
device certificate | A device certificate consists of a ProductKey, a DeviceName, and a DeviceSecret.
|
ProductSecret | A ProductSecret is the private key issued by IoT Platform for each product. A ProductSecret is usually used in pair with a ProductKey for unique-certificate-per-product authentication. ProductSecrets are required in device authentication. You must safely keep them. |
TSL model | IoT Platform uses Thing Specification Language (TSL) to describe device features. A TSL model defines the device properties, services, and events. TSL models use the JSON format. You can organize data based on a TSL model and submit the data to IoT Platform. |
property | A property is a TSL feature that describes the status of a device, such as the temperature information that is collected by an environmental monitoring device. Properties support the GET and SET request methods. Applications can send requests to retrieve and set properties. |
service | A service is a TSL feature that describes the capabilities or methods of a device. These capabilities or methods can be used by external requesters. You can specify the input and output parameters of a service. Compared with properties, services can be called by using a command to implement complex business logic. For example, you can call a service to perform a specific task. |
event | An event is a TSL feature that describes the runtime events of a device. An event contains a notification that requires action or attention. An event may contain multiple output parameters. For example, an event may be a notification that a task is completed, a device fault has occurred, or a temperature alert is generated. You can subscribe to or push events. |
intelligent alerting | LinkVisual defines the alert events for IP cameras based on vision algorithms. The events include motion detection, illegal parking, and facial recognition. |
time template | A time template defines time segments within a week for IP cameras to record videos. After a recording plan is associated with the time template, you can associate an IP camera with the recording plan. This way, the IP camera automatically record and upload videos to IoT Platform based on the conditions specified in the recording plan. |
recording plan | A recording plan defines the conditions that trigger continuous recording or intelligent alerting-specific recording. After you associate an IP camera with the recording plan, the IP camera automatically record and upload videos to IoT Platform based on the specified conditions.
