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 Light Technology
This camera features an intelligent dual-light system that balances stealth and visibility. By default, it uses infrared (IR) for discreet nighttime surveillance. When motion is detected, a white warm light activates to capture full-color video—ideal for identifying faces, clothing, or license plates. After the event, it automatically returns to IR mode to minimize light pollution and avoid disturbing nearby areas.
AcuPick – AI-Powered Search
Integrated with back-end deep learning, AcuPick allows users to quickly locate specific people or vehicles across large volumes of recorded footage. Compatible with Dahua AI NVRs, it filters and displays only the relevant clips—saving time during investigations and dramatically improving search efficiency.
Active Deterrence with Customizable Alerts
The camera includes built-in red and blue flashing lights and a siren that trigger automatically when a predefined event occurs (e.g., line-crossing or intrusion). For tailored responses, you can import your own audio files—making it ideal for commercial storefronts, restricted zones, or gated areas that need real-time deterrent actions.
Smart Motion Detection (SMD 4.0)
SMD 4.0 accurately detects motion caused by humans or vehicles while ignoring distractions like animals, tree branches, shadows, or rain. This ensures that alerts are meaningful and reduces unnecessary notifications—especially useful in outdoor or high-movement areas.
One-Tap Disarming via App
With the Dahua DMSS mobile app, users can instantly disarm motion alerts and deterrent functions with a single tap. This is especially useful during store openings, staff entries, deliveries, or other routine access times—providing both convenience and flexibility without compromising security during critical hours.
More About AcuPick – Precision Video Search Powered by AI
Dahua’s AcuPick feature revolutionizes how you locate events in video surveillance footage. Instead of manually watching hours of clips, AcuPick intelligently filters and finds relevant footage based on AI-classified human or vehicle presence.

Highlights of AcuPick:
-
AI-Driven Precision – Differentiates between humans and vehicles for relevant search results.
-
Smart Filtering – Search using characteristics like clothing color or vehicle type—no need to know the exact time of an incident.
-
Instant Video Recall – Jump straight to key events with a few clicks.
-
False Alarm Reduction – Minimizes alerts triggered by non-critical motion.
-
Flexible Deployment – Works with Dahua’s smart cameras or AI-compatible NVRs.
Practical Applications:
-
Retail & Offices – Trace customer movement or detect unauthorized access.
-
Car Parks & Driveways – Locate vehicle activity instantly.
-
Public Spaces – Search for individuals using visual traits.
-
Gated Residences – Review vehicle arrivals or visitor interactions quickly.
AcuPick transforms passive surveillance into active, intelligent security management—saving valuable time and enhancing operational effectiveness.
