Here’s a breakdown of what makes IVS “intelligent” and how it works:

Key Differences from Traditional Surveillance:

• Proactive vs. Reactive: Traditional systems primarily record footage for later review, acting as a reactive tool for forensics. IVS, however, actively analyzes video in real-time, enabling proactive threat detection and immediate responses.3

• Automation vs. Manual Monitoring: Traditional surveillance heavily relies on human operators to constantly monitor feeds, which can be prone to human error and fatigue.4 IVS automates many of these tasks, reducing the need for constant human supervision.5

• Analysis vs. Recording: IVS goes beyond mere recording.6 It interprets and understands the visual data, identifying patterns, behaviors, and anomalies that might indicate security threats or other events of interest.7

How Intelligent Video Surveillance Works:

1.Data Collection: High-definition cameras, often equipped with advanced features like night vision and wide dynamic range, are strategically placed to capture clear and detailed footage.8 These cameras may also integrate with other sensors (e.g., motion, thermal, audio) for richer data.9

2.Powerful Analytics Engine: At the core of IVS is a powerful analytics engine that uses AI and machine learning algorithms.10 This engine processes the vast amounts of video data collected by cameras and sensors.11

3.Real-time Analysis: The algorithms analyze video feeds in real-time to:12

◦ Detect and Classify Objects: Identify and categorize objects like people, vehicles, animals, or specific items.13

◦ Motion Detection: Differentiate between significant movements (e.g., a human intruder) and irrelevant ones (e.g., swaying trees, animals), reducing false alarms.14

◦ Behavior Analysis: Recognize unusual or suspicious behaviors, such as loitering, running, unauthorized access, or the presence of abandoned/missing objects.15

◦ Facial Recognition: Identify individuals by their facial features, often by comparing them against a database.16

◦ License Plate Recognition: Read and record vehicle license plates.17

◦ People Counting: Count the number of people in a specific area.18

◦ Crowd Management: Monitor crowd density and dynamics to spot potential dangers or congestion.19

4.Anomaly Detection: IVS systems “learn” what constitutes normal behavior and patterns. When an anomaly or something breaks the established pattern, it triggers an alert.20

5.Alerts and Actions: Upon detecting a predefined event or anomaly, the system can automatically:

◦ Send alerts and notifications to security personnel (via email, SMS, etc.).21

◦ Trigger alarms.22

◦ Initiate recording.

◦ Activate other security systems (e.g., access control, lighting).23

◦ Provide real-time situational awareness for a swift response.24

6.Data Management and Insights: IVS systems can store and manage large volumes of video data, extracting valuable metadata for enhanced search capabilities, streamlined video management, and generating insights for better decision-making (e.g., optimizing store layouts in retail, traffic management).25

Key Features and Applications:

• Enhanced Security: Proactive threat detection, intrusion detection, auto-tracking of suspects, and reduced false alarms.26

• Public Safety: Monitoring public spaces, crowd control, traffic management, and incident detection.27

• Retail: Customer behavior analysis, optimizing store layouts, inventory management, and shoplifting detection.28

• Industrial and Critical Infrastructure: Perimeter security, predictive maintenance by monitoring equipment, and compliance monitoring.

• Smart Homes/Businesses: Remote monitoring, alerts for unusual activity, and integration with other smart devices.29

By transforming raw video data into actionable insights, Intelligent Video Surveillance significantly enhances security, safety, and operational efficiency across various sectors.30

1.Product Model and Firmware Version

Any model and firmware with IVS supported. (This tutorial is based on WEB 5.0 firmware)

Interface may vary on some models and firmware.

1.Operation Description

2.Login Device.

3.Enable IVS in AI – Smart Plan.

1.Click Add Rule button to add a new rule and select the IVS rule type.

1.Click Draw Rule Icon to set the rule region / line.

Click rule name can modify it. Click the   icon can delete this rule.

Use left click on the image to draw the rule, right click to end the drawing.

Regional rules will auto close into a region when finished drawing.

1.Set parameters of current rule.

Rule Params: You can set the rule effect period, detection direction, sensitivity  and enable special target filter. Different rule type may have different rule params.

Scenario Requirements

Specific requirements:

12.Scenario requirements: This device is suitable for various indoor and outdoor scenarios with demands on waterproof, IR and high resolution, such as hall, warehouse, canteen, exhibition hall, supermarket, subway platform, square, school gate, and high-altitude panorama.

13.Recommended scenarios: The economical fisheye network camera is mainly used in retail scenarios such as small shops and small supermarkets, and the number of people in the arming region shall be less than 35.

Installation Requirements

For ceiling mount mode, see the following installation requirements:

1. There is sufficient light in the scenario to ensure illumination effect.

2. Avoid a complex scenario with frequently changing light, backlight, and direct light exposure.

3.mountMake the camera face the monitoring center region, so that the intelligent detection will be more accurate. See Figure 2-1.

4. The recommended installation height (H) is 3–4 m. Exceeding this range will affect the accuracy

Installation

• Ceiling Mount

The surveillance image of fisheye products is an original circle and is wider. You need to use multiple devices to monitor a scenario, but one fisheye camera can do this. Use this advantage during installation. In view of the advantages, the ceiling mount is preferred for indoor installation. See Figure 2-2, the small shop is equipped with a ceiling mounted fisheye camera

.

Generally, the indoor floor is 3-4 m away from the ceiling and this height is proper for the economical fisheye cameras. Install the cameras in the middle of the monitored places, thus making the monitored places in the middle of the fisheye cameras, and obtaining most effective images. The project indoor products can be installed higher (6-8 m).

• Wall Mount

Wall mount is needed based on different customer requirements or scenarios. The height selection is vital to wall mount. The mount height might vary according to main surveillance scenarios. If too high, the ceiling is included in the image. See Figure 3-3, the indoor fisheye camera is mounted too high, leading to less effective images.

Therefore, for indoor wall mount, the camera should not be installed too high. Generally, 2-3 m is preferred.

.

Indoor Environment

It is necessary to select proper indoor fisheye products and well install them. The indoor products are not subject to waterproof or explosion proof requirements. Therefore, refer to this for model selection.

• IR Notes

IR devices are less dependent on the environment, so they can perform surveillance efficiently in the dark. In addition, install IR devices against interference from other objects. The fisheye lens enjoys a wide field, so IR reflection will largely affect the image effect. See Figure 2-4, IR reflection occurs when a hand touches the front cover surface during the image shooting test, resulting in abnormal images.

Outdoor Environment

In the outdoor environment, ceiling and wall mount are preferred, not ground mount.

The ceiling mount is generally 6-8 m. For example, the camera installed at the height of 8 m has a wider view than that installed at the height of 6 m. For road panoramic surveillance, see Figure 2-5.

.

Unlike indoor, the outdoor wall mount depends more on the mount bracket than the height. The figure below shows the outdoor wall mount scenarios – monitored gateway and roads.

Arming Data

For fisheye products, the closer to the edge, the greater the distortion of the image, thus the intelligent detection rate of the region close to the image edges reduces. To ensure the effect of intelligent detection, pay attention to the following points when enabling the function:

1. There is sufficient light in the detection image without obstacles.

2. The detected person must be fully exposed (such as the shoulder width).

3. It is recommended that the detection region is within 80% of the image center.

4. The lens surface is free of obstruction, dirt, and other factors that affect the image.
