Situation Analysis

Context

Currently, the intelligent analysis service can be implemented only 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 4-227 shows the process.

Figure 4-227 Implementation using a camera

Configuration Process

Set related parameters on the LDU for situation analysis. Figure 4-228 shows the configuration process.

Figure 4-228 Configuration process

Function Description

Table 4-209 describes the camera intelligence requirements.

Application Limitations

• For details about the data retention period and clearance rules, see Data Clearance Rules.
• To configure intelligent analysis for cameras on the iClient S100, the camera version must be 9.0.0 or later.

Context

• The intelligent attribute of the camera is automatically set to Others when an intelligent analysis function is enabled.
• 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.

Procedure

1. Log in to the LDU as the admin user. ( Logging In to the LDU)
2. Disable global intelligent behavior analysis and target recognition.
   • For details about how to disable global behavior analysis for a camera, see 4.
   • For details about how to disable target recognition for a camera, see Enabling Target Recognition.

3. Set the camera algorithm mode. You need to set the camera algorithm mode only for some camera models. If the camera algorithm mode is not displayed, skip this step.
   1. Click in the upper left corner.

Related Feature Operations

For details about operations related to situation analysis, see the feature guide.

• Queue Length Detection
• Crowd Density Detection
• Head Counting
• Heat Map

Definition

Intelligent cameras detect the queue length in a specified area and generate an alarm when the queue length exceeds the specified threshold.

The system receives and processes queuing information and alarms reported by intelligent cameras.

Customer Benefits

• The system automatically detects key information in video, reducing labor costs and improving work efficiency.
• The system supports around-the-clock detection or detection for a specified duration, eliminating issues that may occur due to security personnel's mistakes.
• Users only need to view live video upon an alarm. This allows a user to centrally manage a large number of cameras, reducing labor costs.

Application Scenario

This feature applies to places where people may need to wait in queues, for example, in bank branches.

Requirements

Application Limitations

Related configurations need to be performed in the camera web system.

Scenario Description

Table 4-211 describes the support for this feature in different client scenarios.

5. Configure an alert plan, as shown in Figure 4-247.
   Figure 4-247 Configuring an alert plan
   

6. Configure an alarm linkage policy, as shown in Figure 4-248.
   Figure 4-248 Configuring an alarm linkage policy
   

   Table 4-227 describes the key parameters and buttons.

   Table 4-227 Parameter/Button description

   Type	Parameter	Description
   Common Linkage	Display ID	Indicates whether to display the status icon of the camera that triggers an alarm on the live video viewing page. This function is used to notify users of an alarm generated by the current camera.
   	Full-Screen Alarm	Indicates whether to display alarms in full screen mode. After this function is enabled, if a camera triggers an alarm and the live video viewing page is displayed on the LDU, the live video of the camera is played in full screen mode for 5s. CAUTION: If other alarms are generated when the live video is played in full-screen mode, the full-screen alarm function is not triggered.
   	Send Email	Indicates whether to send email notifications. After this function is enabled, the system sends an email to the configured email recipient when a service alarm is generated. You can click to customize the alarm email recipient and email body. The email address for sending service alarms needs to be customized on the OMU portal. For details about how to set the email address for sending service alarms, see How Do I Configure Connection to the SMTP Server?.
   Recording	Channel	Camera to be linked to record video when an alarm is triggered.
   	Duration(s)	Customized recording duration. The value ranges from 5 to 3600, in seconds. You are advised to set this parameter to a value greater than or equal to 60 (default).
   Triggered Snapshot	Channel	Camera to be linked to take snapshots when an alarm is triggered. NOTE: If both snapshot taking and email sending are configured for alarm linkage, you can obtain both the alarm-triggered snapshots and the snapshots sent in the email.
   Stop Recording	Channel	Camera to be linked to stop video recording when an alarm is triggered.
   I/O Alarm	Channel ID	Alarm reporting channel.
   	Duration(s)	Customized alarm linkage duration. The value ranges from 1 to 3600, in seconds. NOTE: If the specified alarm linkage duration is different from the I/O alarm output duration configured in How Do I Connect Cables and Configure Alarm Input and Output Ports?, the shorter alarm duration is used. For example, if the I/O alarm output duration is set to 20s and the alarm linkage duration is set to 30s, the actual alarm output duration is 20s.
   Invoke Preset Position	Channel	Camera to be linked. When a service alarm is generated, the linked camera rotates to the specified preset position. Before enabling preset position linkage, ensure that a preset position has been configured for the camera to be linked. For details about how to configure a preset position, see Feature Configuration.
   	Device	Name of the camera that is linked to a preset position.
   	Position	Preset position linked to the camera.

Procedure (on the iClient S100)
