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 for Clear Night Vision
This camera employs a sophisticated Smart Dual Light system, providing optimal night surveillance while minimizing light pollution. During normal nighttime conditions, the camera uses its invisible IR illuminators to capture crisp black and white video. However, the moment a person or vehicle is detected within the monitoring area (thanks to its intelligent algorithms), the bright warm lights automatically activate. This instantly switches the camera to full-color mode, recording vivid, detailed footage of the event. Once the detected target leaves the area, the warm lights turn off, and the camera reverts to IR mode. This intelligent switching ensures crucial full-color evidence when needed, while maintaining discretion and energy efficiency.
SMD 4.0: Precision Motion Detection
SMD 4.0 (Smart Motion Detection) represents a significant leap in alarm accuracy. Instead of traditional motion detection that triggers on any movement, SMD 4.0 leverages advanced deep learning algorithms to distinguish between actual threats (humans and vehicles) and irrelevant movements like animals, rain, or swaying branches. This drastically reduces false alarms, saving you time from reviewing unnecessary alerts and ensuring you're only notified when it truly matters. The system can even allow you to define specific "warm light areas" where SMD will specifically trigger alarms, adding a layer of customizable control.
AcuPick: Rapid Evidence Retrieval
AcuPick is a powerful feature that works in conjunction with compatible Dahua back-end devices (like Smart NVRs). It uses deep learning to quickly and accurately match targets, such as specific people or motor vehicles, across both live and recorded video. This means if you have a suspect description or a vehicle detail, AcuPick can rapidly search through hours of footage to pinpoint relevant events. This significantly speeds up the process of locating critical evidence, transforming laborious manual searches into efficient, automated processes.
AI Scene Self-Adaption (SSA): Optimized Image Quality
The AI SSA feature employs deep learning algorithms to intelligently analyze the scene and automatically adjust the camera's image parameters to suit the prevailing conditions. Whether it's bright sunlight, heavy shadows, or low-light environments, AI SSA dynamically optimizes settings like exposure, gain, and white balance. This ensures that the camera consistently produces clear, vivid, and well-exposed images, eliminating the need for constant manual adjustments and guaranteeing high-quality footage regardless of the lighting challenges.
Active Deterrence: Stopping Threats Before They Escalate
The IPC-HDBW3849R1-ZAS-PV-ANZ-S2 goes beyond mere recording by offering robust active deterrence. When a perimeter violation (like intrusion or tripwire) is detected, the camera immediately triggers a multi-faceted response: bright red and blue strobe lights flash rapidly, and a loud siren sounds. This combination is designed to startle and deter potential intruders on the spot, often preventing an incident from escalating further. The ability to upload customized voice messages for the siren allows for even more tailored and effective warnings.
Seamless Integration with AI NVRs and Mobile Apps
This camera is designed for seamless integration into a comprehensive security ecosystem. When paired with Dahua Smart NVRs, you unlock the full potential of its AI capabilities, including advanced search functions and event aggregation. For remote monitoring and control, the camera is fully compatible with Dahua's mobile clients (iOS and Android apps like DMSS) and management software (SmartPSS Lite, DSS). This allows you to view live feeds, review recordings, receive instant alerts, and manage camera settings from virtually anywhere in the world, providing complete control over your security.
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.

Q&A
Q1: Can this camera record in full color at night? A1: Yes, this camera features Smart Dual Light technology. It records in black and white using IR light by default at night, but if a human or vehicle is detected, the warm white lights will automatically turn on, allowing the camera to record the event in full color.
Q2: How loud is the built-in speaker, and can I use it to talk to someone? A2: The camera has a built-in speaker and dual microphones, enabling two-way talk. While the exact decibel level isn't specified, the speaker is designed to be loud enough for effective communication and for the siren alarm to be a strong deterrent.
Q3: Can the red and blue active deterrence lights be disabled or scheduled? A3: Yes, the active deterrence features, including the red and blue lights and siren, can typically be configured and scheduled through the camera's interface or the associated mobile app (like DMSS). This allows you to enable or disable them based on your specific needs and time of day.
Q4: Is this camera compatible with NVRs from other brands, or only Dahua NVRs? A4: This camera supports ONVIF (Profile S, G, T) and CGI, which means it should be compatible with many third-party NVRs that also support these standards. However, to fully utilize all the advanced AI features like AcuPick and Smart Search, it is recommended to pair it with a compatible Dahua Smart NVR.
Q5: How long can the 512GB Micro SD card record for? A5: The recording duration on a 512GB Micro SD card will vary significantly based on factors like the recording resolution, frame rate, compression (H.265 vs. H.264), and the amount of motion in the scene. With efficient H.265 AI coding and intelligent recording modes (e.g., motion-triggered), it can store several weeks to months of footage, but continuous 8MP recording will fill it much faster.
Q6: What is the main difference between this WizSense camera and a standard security camera? A6: The key difference is the "WizSense" AI capability. This camera incorporates an independent AI chip and deep learning algorithms, enabling highly accurate human and vehicle detection (SMD 4.0, IVS), active deterrence, and advanced image optimization (AI SSA). This means far fewer false alarms and more intelligent, proactive security compared to standard cameras that rely on basic motion detection.
