Behavior Analysis

Principles

This intelligent service can be implemented:

• On cameras

  Cameras perform intelligent analysis using its own algorithm, and report alarms and snapshots to the HWT-IVS1800. The HWT-IVS1800 stores and manages alarms and displays alarms on the client. Figure 4-114 shows the process.

  Figure 4-114 Implementation using a camera
  
• On the HWT-IVS1800

  Cameras directly send video to the HWT-IVS1800. The HWT-IVS1800 performs intelligent analysis based on its own algorithms, stores and manages alarms, and displays alarms on the client. Figure 4-115 shows the process.

  Figure 4-115 Implementation using the intelligent storage device
  

Configuration Process

• The behavior analysis function implemented on intelligent cameras can be configured on the LDU or in the camera web system.

  Figure 4-116 shows the configuration process on the LDU. For details about the configuration in the camera web system, see the product documentation of the corresponding camera.

  Figure 4-116 Configuration process
  
• Behavior analysis using the HWT-IVS1800 intelligence can be configured only on the LDU. Figure 4-117 shows the process of configuring behavior analysis on the LDU.

      Table 4-98 Parameter/Button description

      Parameter/Button	Description
      	Button for enabling or disabling global behavior analysis configuration.
      Min Target	Minimum resolution of an object that can be detected on video images in the CIF (352 x 288) resolution. No alarm is generated when the resolution of a detected object is less than the value of this parameter.
      Max Target	Maximum resolution of an object that can be detected on video images in the CIF (352 x 288) resolution. No alarm is generated when the resolution of a detected object is greater than the value of this parameter.
      Target Detection Sensitivity	Sensitivity for triggering target detection alarms. The options include lower, low, standard, high, and higher. Higher sensitivity indicates a higher possibility of triggering alarms, which may lead to false alarms. For example, after you set high sensitivity for intrusion detection, a false alarm may be reported when a target passes by a sensitive area. Lower sensitivity indicates a lower possibility of triggering alarms, which may lead to missing alarms. For example, after you set low sensitivity for tripwire crossing detection, an alarm may not be reported when a target passes one end of a tripwire.
      Max Objects	Maximum number of objects for intelligent analysis. Set this parameter as prompted.
      Send only the first alarm of a single target	Indicates whether to allow the camera to send the alarm only once for the same alarm event.
      Send Metadata	The function is enabled by default. Indicates whether to send metadata updates. After this function is enabled, the camera will send metadata updates such as intelligent analysis rules and intelligent analysis results as well as live video to the upper-level video and image management platform. If the platform requests metadata streams, enable this function.
      Metadata sending panorama	The function is enabled by default. Indicates whether to allow the camera to send the full image, object frame, and rule frame generated upon alarm occurrence as matadata to the upper-level video and image management platform. Then the platform can superimpose the object frame and rule frame on the full image. You are advised to enable this function in behavior analysis scenarios.
      Alarm sending panorama	Indicates whether to allow the camera to send the full image as general metadata when an alarm is generated to the video security platform.
      Superimpose target frames on full images	Indicates whether to allow the camera to send the full image, object frame, and rule frame generated upon alarm occurrence as matadata to the upper-level video and image management platform. You are advised to disable this function in behavior analysis scenarios.
      Shadow Removal Mode	Mode in which the shadow is removed. The shadow generated when objects are moving affects the detection size. Set the parameter based on the site requirements. NOTE: In a scenario with no shadow or small shadows, Weak shadow is recommended to ensure complete detection of objects. In a scenario with obvious large shadows, Strong shadow is recommended to cut objects from shadows to make bounding rectangles closer to the object sizes or cut objects overlapped with shadows to separately display the objects.
      Background Update Frequency	Speed of integrating an object into the background. A larger value indicates quicker object integration.

Prerequisites

You have installed the behavior analysis algorithm plug-in on the HWT-IVS1800.

Scenario Description

• After local intelligence is enabled or an analysis task is created for a camera, do not modify the attributes of the camera. Otherwise, target recognition and video structuring tasks will become invalid, and you will need to delete and recreate the tasks.
• Cameras have been configured to synchronize time with the HWT-IVS1800. This function is enabled by default. For details, see Configuring Time Synchronization from a Camera to the HWT-IVS1800.

Definition

The system automatically generates an alarm when an intrusion is detected.

• Allows users to specify multiple polygonal detection areas.
• Detects and distinguishes multiple objects that enter a specified area, and generates alarms.
• Displays alarm information including the alarm type, occurrence time, duration, and object labeling.

Customer Benefits

The system automatically detects key information in video feeds through intelligent analysis, reducing labor costs and improving detection efficiency. Different intelligent analysis functions apply to different scenarios.

Application Scenario

If no one is allowed to enter or approach an area, the intrusion detection function can be used to keep the area under detection.

Requirements

Application Limitations

• Onsite conditions such as illumination and shooting angles affect the detection accuracy.
• This feature is supported only by cameras connected through HWSDK.

Definition

The system automatically generates an alarm when an object is detected abandoned in a specified area. The system connects to cameras that support abandoned object detection to provide the following functions:

• Allows users to set analysis parameters, including detection areas (rectangle or polygon).
• Allows users to specify an acceptable object abandoned duration (10s to 300s). When the duration has elapsed, the system generates an alarm.
• Allows users to superimpose analysis results on live or recorded video images with a rectangular box (different objects are marked with different rectangular boxes) and label the object that triggers the alarm on video images.
• Allows users to record alarm information and trigger predefined alarm linkage actions.

Customer Benefits

The system automatically detects key information in video feeds through intelligent analysis, reducing labor costs and improving detection efficiency. Different intelligent analysis functions apply to different scenarios.

Application Scenario

Definition

The system automatically generates an alarm when an object is detected removed from a specified area. The system connects to cameras that support removed object detection to provide the following functions:

• Allows users to set analysis parameters, including detection areas (rectangle or polygon).
• Allows users to set the duration (10s to 300s) when an object is removable. When the duration has elapsed, the system generates an alarm.
• Allows users to superimpose analysis results on live or recorded video images with a rectangular box (different objects are marked with different rectangular boxes) and label the object that triggers the alarm on video images.
• Allows users to record alarm information and trigger predefined alarm linkage actions.

Customer Benefits

The system automatically detects key information in video feeds through intelligent analysis, reducing labor costs and improving detection efficiency. Different intelligent analysis functions apply to different scenarios.

Application Scenario

This feature is applicable to areas that are alert to object removal, for example, museums and exhibition halls.

Requirements

Application Limitations

• Onsite conditions such as illumination and shooting angles affect the detection accuracy.
• This feature is supported only by cameras connected through HWSDK. In addition, this is a PoC feature of cameras, and can be used only for PoC testing on the platform.

Definition

The system generates an alarm when an object is detected exiting a specified area.

• Allows users to specify multiple polygonal detection areas.
• Detects and distinguishes multiple objects that exit a specified area, and generates alarms.
• Displays alarm information including the alarm type, occurrence time, duration, and object labeling.

Customer Benefits

The system automatically detects key information in video feeds through intelligent analysis, reducing labor costs and improving detection efficiency. Different intelligent analysis functions apply to different scenarios.

Application Scenario

This feature is used to detect objects that exit a key protection area.

Requirements

Application Limitations

• Onsite conditions such as illumination and shooting angles affect the detection accuracy.
• Alarms can be triggered concurrently for a maximum of nine objects.
• Currently, this feature is not supported on the iClient S100.

Scenario Description

Table 4-169 describes the support for this feature in different client scenarios.

Prerequisites

• You have connected a camera that supports intelligent analysis.
• You have set the parameters listed in Setting Global Parameters (Configuring Frontend Behavior Analysis on the LDU) on the LDU.

   Table 4-170 describes the key parameters.

   Table 4-170 Parameter/Button description

   Type	Parameter/Button	Description
   Detection Area	Detection Object	Type of objects that can be detected. Pedestrian Motor vehicle Non-motorized vehicle
   	No.	ID of a detection area. A maximum of four detection areas can be drawn.
   	Operation	Column containing the icons for drawing or deleting a detection area on the live video image.
   	Switch	Button for enabling or disabling a detection area.
   Sound And Light Alarm NOTE: The configurations of this function cannot be applied to other devices.	Audio switch/Twinkle switch	Indicates whether to produce audible alarms (playing audio files) or visual alarms (blinking light) when an alarm is triggered.
   	Audio Output	Audio file to be played when an alarm is triggered. You can directly use this function when an intelligent IR/white-light camera with intercom is used. To use this function when a camera other than the intelligent IR/white-light camera with intercom is used, you need to set audio parameters for the camera and connect the camera to an external audio output device.
   	Frequency	Number of times for playing an audio file when an alarm is triggered.
   	Twinkle Freq	Frequency at which the light blinks when an alarm is triggered. You can set this parameter to Low frequency, Medium frequency, or High frequency as required. Currently, the visual alarm (blinking light) function is available only for intelligent IR/white-light cameras with intercom. You need to set light-related parameters.
   	Twinkle Time(s)	Period in which the light blinks when an alarm is triggered.
   Alarm Settings	Alarm Sensitivity	Detection sensitivity of the system. The value ranges from 1 to 100. A larger value indicates higher sensitivity.
   	Alarm Interval (s)	Interval at which alarms are checked, in seconds.
   	Pre-determined Alarm Position	Part of an object based on which detection is performed. Center: An object can be detected only when its central part enters the detection area. Top: An object can be detected only when its top part enters the detection area. Bottom: An object can be detected only when its bottom part enters the detection area. The criteria for determining whether an object enters the detection area are related to Pre-determined Alarm Position. For example, if Pre-determined Alarm Position is set to Center, an alarm is triggered when the central part of an object enters the detection area.

5. Configure an alert plan, as shown in Figure 4-187.
