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
The Smart Dual Light feature is a significant advantage for 24/7 monitoring. At night, the camera typically operates in infrared (IR) mode, providing black and white video while conserving power and reducing light pollution. However, the moment a human or vehicle is detected in the monitoring area, the camera automatically switches on its warm white light, immediately capturing full-color video of the event. This means you get vivid, detailed recordings of crucial incidents, making identification much easier. Once the detected target leaves the area, the white light turns off, and the camera reverts to IR mode, ensuring efficient operation and minimal disturbance. This intelligent switching ensures you get the best of both worlds: discreet monitoring and high-quality, full-color evidence when it matters most.
SMD 4.0 (Smart Motion Detection)
Dahua's SMD 4.0 is more than just basic motion detection. Powered by advanced AI algorithms, it intelligently distinguishes between actual threats (humans and vehicles) and insignificant movements caused by animals, rain, leaves, or even changes in lighting. This significantly reduces false alarms, saving you time and effort from reviewing unnecessary alerts. You'll receive accurate notifications for events that truly matter, allowing you to focus on genuine security concerns. This smart filtering makes your security system far more efficient and reliable.
AcuPick
AcuPick revolutionizes how you search through recorded footage. Instead of sifting through hours of video, this feature, when paired with a compatible back-end device, uses deep learning to rapidly locate specific targets like people or motor vehicles within your recorded and live video. Imagine needing to find out who accessed a certain area at a specific time; AcuPick can quickly pinpoint all instances of human or vehicle presence, drastically cutting down investigation time and improving response efficiency. It's like having a highly intelligent search engine for your surveillance footage.
AI Scene Self-Adaption (AI SSA)
AI SSA allows the camera to intelligently adjust its image parameters based on the specific environmental conditions it's operating in. This means the camera can automatically optimize its settings for varying light levels, weather conditions, or even scene complexities without manual intervention. Whether it's a bright sunny day, a foggy morning, or a dimly lit night, AI SSA ensures that the camera consistently captures clear and high-quality images, providing reliable surveillance regardless of the scene.
Active Deterrence (Lights + Audio)
This camera goes beyond just recording; it actively discourages intruders. When a pre-defined event like intrusion or tripwire is triggered, the camera's built-in red and blue strobe lights activate, along with a powerful siren. This immediate and noticeable response is designed to startle and deter potential threats, making them think twice before proceeding. You can even upload customized voice messages to be played, adding a personal and potentially more effective deterrent, such as "Warning: You are being recorded." This proactive approach adds a significant layer of security to your property.
Integration with AI NVRs and Mobile Apps
The DH-IPC-HFW3549T1-ZAS-PV integrates seamlessly with Dahua's AI Network Video Recorders (NVRs) for advanced analytics and centralized management. This allows you to leverage features like Smart Search for quick event retrieval and a more robust surveillance system. For on-the-go monitoring, the Dahua mobile client (DMSS) for iOS and Android enables remote viewing of live feeds, playback of recordings, and control of camera settings, including the convenient "One-tap Disarming" function, which lets you easily arm or disarm event linkages directly from your phone. This flexible integration ensures you have control and access to your security system whenever and wherever you need it.
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.
