What is TIOC?
TiOC stands for Three-in-One Camera, combining Full-Colour Video, Active Deterrence, and AI Detection into one powerful security solution.
With TiOC cameras, you get:
-
Full-Colour Footage 24/7 – even at night, thanks to Smart Dual Illuminators.
-
Smart AI Detection – accurately identifies humans and vehicles, filtering out false
alarms caused by animals, trees, or shadows.
-
Active Deterrence – red and blue warning lights plus a loud siren to stop intruders in their tracks.
These features work together to give you fast, accurate alerts and clear footage any time of day.
How Does It Work?
1. Full-Colour Night Vision with Smart Dual Illuminators
TiOC cameras automatically switch between infrared and LED lighting. When no threat is detected, they use discreet IR. When a person or vehicle enters the scene, the LED lights activate to record in full colour—helping you capture every detail clearly.



2. AI-Powered Detection
Using SMD 4.0 (Smart Motion Detection) and Perimeter Protection, the camera can tell the difference between a person, vehicle, animal, or object. This means:
- You get alerts only when it matters.
- False alarms are reduced to less than 1%.

3. Active Deterrence
When a genuine threat is detected, the camera activates built-in red and blue strobe lights along with a loud audible siren to immediately deter intruders. This proactive response helps prevent incidents before they occur. Users can schedule deterrence features to operate during specific hours—such as overnight—or customise them to suit their needs. For added convenience, a one-touch disarm function allows quick cancellation of the siren when necessary.

Extra Info
Smart Dual Illumination
The Smart Dual Light feature is a game-changer for night surveillance. Under normal low-light conditions, the camera uses its invisible IR illuminators to provide clear black and white video, minimizing light pollution. However, the moment its intelligent algorithms detect a human or vehicle in the monitoring area, the warm white light automatically activates. This illuminates the scene, allowing the camera to capture full-color video of the key event. Once the detected target leaves the area, the white light turns off, and the camera reverts to IR mode. This not only provides richer, more evidential footage but also helps conserve energy and avoid constant bright illumination in quiet periods.
SMD 4.0
SMD 4.0, or Smart Motion Detection 4.0, represents a significant leap in intelligent alarm filtering. Unlike traditional motion detection that can be triggered by anything from a passing animal to falling leaves, SMD 4.0 leverages deep learning algorithms to precisely classify targets as either humans or vehicles. This drastically reduces false alarms, ensuring that you only receive notifications for events that truly matter. Installers can even define specific "SMD areas" within the warm light zones, allowing for targeted alarm triggers in illuminated spaces.
AcuPick
AcuPick is a powerful post-event search tool that works in conjunction with compatible Dahua back-end devices (like Smart NVRs). After an event, instead of sifting through hours of footage, AcuPick uses deep learning to quickly and accurately match targets, such as specific people or motor vehicles, across live and recorded videos. This feature is invaluable for rapidly locating evidence, streamlining investigations, and saving significant time for security personnel.
AI Scene Self-Adaption (SSA)
AI SSA uses advanced deep learning algorithms to constantly analyze the scene and automatically adjust the camera's image parameters. This means the camera intelligently optimizes settings like brightness, contrast, and exposure to suit the changing conditions, whether it's bright daylight, a foggy morning, or deep twilight. The result is consistently clear and balanced images without the need for manual adjustments, ensuring optimal video quality around the clock.
Active Deterrence (Lights + Audio)
The IPC-HDW3649H-ZAS-PV-ANZ-S2 takes security beyond passive monitoring with its active deterrence capabilities. Upon detecting an intrusion or tripwire event (specifically by a human or vehicle), the camera can automatically trigger bright, attention-grabbing red and blue flashing lights. Simultaneously, its built-in speaker can emit a loud siren or play a pre-recorded custom voice message. This immediate, multi-sensory response acts as a powerful deterrent, often preventing incidents before they escalate and providing an early warning system. The ability to upload customized audio messages allows users to tailor the deterrence message to their specific needs, for example, "Warning! This area is under surveillance, please leave immediately."
Integration with AI NVRs and Mobile Apps
This camera is designed to integrate seamlessly within the Dahua ecosystem. When paired with a Dahua Smart NVR, advanced features like AcuPick and Smart Search become available, enabling intelligent event extraction and merged event videos for efficient review. For day-to-day management and remote access, the camera is fully compatible with Dahua's SmartPSS Lite, DSS, and DMSS mobile client (iOS and Android). These applications allow users to view live feeds, receive real-time alerts, review recorded footage, and even utilize the one-tap arming/disarming function for convenient control from anywhere.
Cybersecurity Protections
Dahua builds in strong cybersecurity protections including encrypted video streams, secure firmware updates, and access controls. This guards against data breaches or unauthorized remote access — a key consideration for business and home networks alike.
