TiOC 2.0 for smarter surveillance

The upgraded TiOC 2.0 features Smart Dual Illumination technology that can flexibly switch between IR mode and white light mode

With Dahua’s TiOC 2.0 customisable security alarms are made possible

Traditional monitoring systems often face a myriad of challenges: excessive usage of white light just to capture colour images; ubiquitous background noise; complicated alarm accessories; and lack of integration with thirdparty alarm systems, just to name a few. In response to these issues, Dahua Technology has launched its upgraded Three-in-One Camera series – the TiOC 2.0. Aside from its Active Deterrence function, it is also equipped with Smart Dual Illuminators, VoiceCatcher technology and other intelligent features. VoiceCatcher technology

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 selfdeveloped noise reduction algorithm and highperformance 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

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 a F1.0 large aperture lens. It is the first Dahua Network Camera with such a feature.

Smart dual illuminators

The upgraded TiOC 2.0 features Smart Dual Illumination technology that can flexibly switch between IR mode and white light mode. The smart illumination mode adopts deep learning algorithm to detect a 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.

AI features

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