Full-color: Smart Dual Light

What is Dahua Smart Dual Light Technology?

The Dahua Smart Dual Light technology adopts smart algorithm to accurately detect targets. The IR illuminator is normally on at night. When the target is detected by the camera, the warm light turns on and the camera records the full-color video and information of key events. When the target is out of the monitored area, the warm light turns off and the IR illuminator turns back on, which helps reduce light pollution in the area.

Key Features

Smart Dual Light: Flexible switching between Full-color and IR modes

• Smart Illumination (Default): Switch between IR Illuminator and warm light when a target is detected.

  • Human target is out of the monitored area

  • Human target is detected by the camera

  • Human target leaves the monitored area

*For HAC cameras, switching between IR illuminator and warm light is integrated with Perimeter Protection or SMD Plus of the AI XVR.


• IR Mode (Optional): Only the IR illuminator is ON. It is suitable for scenes where supplementary warm light is not required, significantly reducing light pollution.

• Warm Light Mode (Optional): Only the warm light is ON. It is suitable for scenes that require color video footages.

IR Mode(Optional)

IR illuminator is ON throughout the whole process Environment friendly and reduces light pollution

Warm Light Mode(Optional)

Warm illuminator is ON throughout the whole process Records full-color video and captures event details

Mobile App: Remotely manage camera illumination anywhere, anytime

Illumination By Schedule: Set illumination modes according to different time periods

Illumination Plan

Illumination Modes

  • Smart Illumination
  • Warm Light Mode
  • IR Mode

Time Periods

  • 7 days, Sunday – Saturday
  • 24-hour cycle

*This feature will be implemented on Dahua Smart Dual Light IPC.

SMD Plus: Smart Motion Detection Plus

Equipped with deep learning algorithm, the Dahua SMD Plus focuses on human and vehicle targets and filters out false alarms triggered by irrelevant objects.



*For HAC cameras, this function works with AI XVR. PTZ cameras only support SMD (human detection) at the moment.


Perimeter Protection

Powered by deep learning algorithm, the Dahua Perimeter Protection technology can accurately recognize human and vehicle targets. In restricted areas such as pedestrian zones and parking lots, false alarms caused by irrelevant objects can be significantly reduced.

Traditional IVS

Missed and false alarms

Inefficient video search functionality

Poor adaptability

Perimeter Protection

Human and vehicle classifications.

Quick Search function

Suitable for a variety of scenarios

*For PTZ and HAC cameras, this function works with AI back-end products.

Smart Search

Extract and classify human and vehicle targets from a massive amount of video data, making it easier for end users to trace and analyze data history. Human and vehcile search options are available for playback to quickly locate the target of interest and save time.

*For PTZ and HAC cameras, this function works with AI back-end products.

Scenario Applications

Retail Store

Pain Points

For retail stores, when a burglary occurs after business hours, owners need to be able to obtain color images for evidence. However, the constant warm light from the camera can disturb other people living near the shop.

Solution

The IR mode is ON during operating hours, and switches to Smart Illumination mode when the store closes at night, which can help reduce light pollution in the area. Users can customize the illumination modes according to their own needs.

Park

Pain Points

At night, some application scenarios cannot visibly recognize people and vehicles due to lack of sufficient light, such as courtyards, parks, etc. White light is used to capture target’s details in these scenarios. However, constant usage of supplementary white light can contribute to the light pollution in the monitored area.

Solution

There are normally no people or vehicles in parks or other similar scenarios late at night. During this idle time, the warm light is turned off, and will only turn back on when a target is detected. When the target leaves the monitored area, the warm light will turn off and the IR illuminator will turn back on. It can significantly help reduce light pollution while ensuring effective monitoring at night.
