TiOC 2.0

What is TiOC 2.0?

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.

Key Features

Smart Dual Light

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

  • IR illuminator is on at night.

  • Warm light turns on (PTZ Tracking) when a target appears.

  • Siren and light turns on (Active Deterrence) to warn the target.

  • Warm light turns off (PTZ back to preset) and IR illuminator turns back on when the target disappears.

• 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.

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.

Focus for visible light and IR light cannot be achieved on the same plane when using F1.0 large aperture.
Focus for visible light and IR light can be achieved on the same plane.

With the OPC technology, the details of the tree are clear, and the edges of the image are bright.

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

  • Normal 4K Non-Real-Time

  • Enhanced 4K Real-time

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.

  • Store:"Welcome"

  • Dangerous Place: "No Entry"

  • Fire Exits: "No Parking"

  • Construction Sites: "Keep Out"

AI Features
SMD 4.0: Reduces false alarms caused by animals

With upgraded AI capabilities, the SMD function filters out irrelevant objects in the scene. Equipped with new deep learning algorithm, SMD 4.0 is optimized to filter out small and large animals in the scene to avoid triggering false alarms.

Perimeter Protection

The perimeter protection function based on tripwire and area intrusion sends an alarm only when unwanted movements triggered by human or vehicle targets occur, saving users from unnecessary actions caused by false alarms.


With the continuous development of video surveillance and AI, the demand for images with higher quality is also increasing.
The Dahua AI SSA (Scene Self-adaption) technology is based on deep learning algorithm that can intelligently identify multiple scenes and adjust to their optimal images.

Auto Tracking 3.0 (PTZ)
Smooth Tracking Process

Combined with PFA 3.0 algorithm (a deep fusion of intelligent algorithms and focusing algorithms), it realizes touchless focusing during the tracking and capturing process.

Long Tracking Distance

With the Automatic Tracking 2.0 algorithm as its foundation, the requirements on the tracking size of the target are further reduced, making the target size smaller and the tracking distance longer. The tracking distance of Automatic Tracking 3.0 can reach up to 870 meters.

Human Tracking Distance:

Vehicle Tracking Distance:


    • Private Places

      • Less Light Pollution: Less use of white light means less light pollution

      • Active Deterrence: Warn off intruders during the intrusion

      • Color Monitoring: Presents color alarm videos

      • Scenarios: Villas, shops, warehouses, etc.

    • Public Areas

      • Active Deterrence: Customized sounds and light alarm to warn the target in the area

      • Accurate Detection: Focuses on human and vehicle targets to accurately identify real targets

      • Ecosystem: One-tap disarming with alarm-in port or DMSS.

      • Scenarios: Fire exits, emergency exits, etc.
