Dahua Auto Tracking


Dahua Auto tracking is a unique technology of the PTZ camera based on the PTZ system. When a target triggers the IVS rule, the camera uses its horizontal/vertical rotation and zoom features to lock the moving target in the center of the screen. Equipped with AI algorithm, the camera can predict the direction and speed of a moving object which allows it to continuously track the target.

Auto Tracking 3.0

The new Auto Tracking 3.0 has a variety of upgraded AI technologies based on the 2.0 algorithm. The tracking performance has been further improved in all three areas that customers focus on.


Smooth Focus
The PFA 3.0 focusing technology realizes deep integration of intelligent algorithms and focusing algorithms, effectively improving the focusing output during tracking and capturing, and realizing smooth focus.
Accurate Zooming
The position adaptive algorithm merges deep learning-based target detection technology and 3D positioning technology, keeping the target in the center of the image with the right proportion.
Fast Moving Tracking
The speed adaptive algorithm can adjust the speed of the PTZ camera’s rotation, zoom and image exposure according to the target’s speed, making the whole tracking process continuous, smooth and without sudden changes. Even fast-moving cars can be tracked.

The PTZ camera can track the complete movement of the target within the monitoring range, providing security personnel where the target goes.

Long Tracking Distance
The new DPT technology can calculate the tracking target frame more accurately. It is capable of tracking smaller targets and further improves the tracking distance. In ideal conditions, it can reach up to 1,500 meters.
Filtering Interference
The interference filtering algorithm can accurately estimate the target’s moving direction, step size and speed according to the characteristics of the target motion vector. The target can be continuously tracked even in complex scenes with occlusion, interlacing, light changes, etc.

Application: PTZ Tracking with Alarm Linkage

· Pain Points
1. The alarm sensor has no video and cannot provide specific visual images of the site.
2. Security personnel have to be on-site to confirm the situation.
· Solution
PTZ camera linked with alarm sensor that can provide visual images of the site and track targets on the scene.
· Advantages
1. One PTZ camera can be linked with multiple alarm sensors, and flexibly supplement image information of the alarm location.
2. Reduce the workload of security personnel and effectively improve equipment utilization.

Dahua TiOC 2.0 Camera


With its foundation from the previous generation of TiOC, a variety of new innovative technologies are introduced in the latest TiOC 2.0 for the first time, achieving breakthroughs and quality improvements in illuminators, audio and images. At the same time, TiOC 2.0 can be integrated with alarm system through software upgrades. It provides better ecosystem that offers more convenient operation and better user experience.

Smart Dual Illuminators

• Smart Illumination Mode (Default): Switch between IR Mode and white light when target is detected.

• 4K Real-time: Smooth 4K real-time images at 30 fps even when AI is enabled, with high brightness using F1.0 large aperture.

Easy Operation

• Alarm-in Port: Allows alarm receiving or one-tap disarming through the alarm system interface.

• One-tap Disarming: Turns on/off the warning light and siren via the DMSS or alarm-in port.

• Alarm Sounds: Offers 11 built-in sounds and supports importing of custom voice audio for different scenarios.

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

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

VoiceCatcher Technology

• Newly-designed Dual Mic Array intercepts external circuit interference.

• Audio pick-up distance is increased by 7 meters compared with the previous version of TiOC in a lab environment.

• The Dahua VoiceCatcher reduces noise and extracts audible audio signals.

Better Image

• First Dahua camera powered by OPC (Optical Path Technology). It corrects the refraction angle of different light path. With F1.0 large aperture lens, it outputs brighter and clearer black & white images.
