Smart Dual Illuminators: Flexible lighting modes

The upgraded TiOC 2.0 features Smart Dual Illumination technology can flexibly switch between IR mode and white light mode. The smart illumination mode adopts deep learning algorithm to detect target, when the Smart Illumination Mode (default mode) is enabled, the supplementary white light will only turn on when a target has been detected in the monitored area (PTZ camera tracks the target). The active alarm will be triggered as well (siren and blue & red light) if the target enters the rule area. When the target leaves the monitored area, the supplementary white light will turn off (PTZ camera goes back to preset) and the IR illuminator will turn back on, which can significantly help reduce light pollution during night time. Together with other modes including IR Mode and White Light Mode, the smart dual illumination technology can meet various scene requirements of customers.

VoiceCatcher Technology: Purer voice audio, farther pickup distance

The Dahua VoiceCatcher technology adopts a high-sensitivity dual mic array – a newly designed audio acquisition circuit that can intercept external circuit interference. With Dahua’s self-developed noise reduction algorithm and high-performance SOC, this feature significantly increases the camera’s audio pick-up distance by 7 meters compared with the previous generation of TiOC (based on standard laboratory environment).


In addition, the VoiceCatcher technology can also reduce noise and extract audible audio signals, which greatly enhance the TiOC 2.0 cameras in terms of sound quality. These dual mic cameras provide clear sound, high wind noise reduction rate, and low environmental background noise, whereas a typical single mic produces a slightly distorted sound. Combined with built-in speaker, a dual mic array greatly enhances the device’s Two-way Talk function, providing clearer and more audible sounds.

Better Image: New low-light image experience

Normally, the focus for visible light and IR light cannot be achieved in the same plane when the camera uses F1.0 large aperture. Focusing on an area in the monitored scene using cameras with these specs is difficult.

Powered by OPC (Optical Path Compensation) technology, the TiOC 2.0 cameras can correct the angle of refraction of different light rays, allowing Dahua IPCs to output brighter and clearer black & white images with F1.0 large aperture lens. It is the first Dahua Network Camera with such feature.

Moreover, Dahua innovatively adopts F1.0 super large aperture which greatly improves image quality (IR cameras on the market mostly have F1.6 aperture). The F1.0 aperture lens of TiOC 2.0 cameras increases the light input by 1.96 times and 2.56 times compared with F1.4 and F1.6 respectively. This technological breakthrough enables a smooth visual experience with high brightness and real-time 4K resolution at 25/30 fps even when AI is enabled.

Ecosystem: Convenient functions for easy operation


Aside from the DMSS app, the TiOC 2.0 camera series also works with WEB/NVR software. It allows configuration of alarm-in ports directly on the webpage interface, providing alarm receiving or one-tap arming/disarming function that can control both siren and warning lights with just a click of a button through the alarm system interface. It features 11 built-in alarm sounds and supports importing of custom voice audios that can be used as a welcome message in stores and as a deterrent in restricted areas.

AI Features: Enhanced detection of events


This upgraded series also adopts AI algorithm instead of conventional PIR sensors to improve its event detection accuracy. It boasts an array of AI functions, including SMD 3.0, Perimeter Protection, making it suitable to various application scenarios including public areas and private places.
