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 Clearer Night Vision
The Dahua Smart Dual Illuminators technology enhances night surveillance by intelligently adapting to the scene. During typical nighttime conditions, the camera uses its invisible IR illuminator to capture clear black and white video. However, when a human or vehicle is detected within the monitoring area, the warm light automatically activates. This not only allows the camera to record crucial full-color video of the event, linking it directly to snapshots, but also acts as an additional deterrent. Once the detected target leaves the area, the warm light switches off, and the camera reverts to IR illumination, effectively minimizing light pollution and ensuring discrete monitoring when no active threat is present. This intelligent switching saves power and extends the lifespan of the warm light.
SMD 3.0: Accurate Detection, Fewer False Alarms
Dahua's Smart Motion Detection (SMD 3.0) leverages advanced deep learning algorithms to provide highly accurate detection of humans and vehicles. Unlike traditional motion detection that can be triggered by irrelevant movements like swaying trees, rain, or small animals, SMD 3.0 intelligently categorizes targets. This means you receive alerts only for events that truly matter, significantly reducing false alarms and ensuring your attention is directed towards real security threats. The system can even distinguish between different types of vehicles, offering even greater precision in specific scenarios.
Active Deterrence: Stopping Threats Before They Escalate
The active deterrence feature of this camera goes beyond mere recording. Upon detection of an intrusion or tripwire event, the camera immediately triggers a powerful siren and flashing red and blue lights. This immediate, attention-grabbing response is designed to startle and deter potential intruders before they can cause harm or damage. The built-in speaker also supports customized voice messages, allowing you to personalize the warning for specific situations. This proactive approach significantly enhances the security of your property by actively intervening in unfolding events.
Seamless Integration with Smart NVRs and Mobile Apps
This WizSense camera is designed to work seamlessly with Dahua Smart NVRs, unlocking even more powerful features. When paired, you can utilize intelligent search functions to quickly locate specific events based on human or vehicle detection. The NVR can also extract and merge event videos, creating a streamlined timeline of critical incidents for easier review. Furthermore, the camera integrates with Dahua's mobile applications (DMSS), providing convenient remote monitoring, two-way talk functionality, and the innovative One-Tap Disarming feature. This allows you to control alarm linkages with a simple tap on your smartphone, adapting the camera's behavior to different scenarios, such as when you are home versus away.
Q&A Section
Can this camera record in color at night?
Yes, the camera can record in full color at night when its "Smart Dual Illuminators" feature is activated, and it detects a human or vehicle within the monitoring area. Otherwise, it will record in black and white using its IR illuminator.
How loud is the siren on this camera?
The siren is designed to be loud enough to effectively deter intruders and draw attention to the event. While a specific decibel level isn't provided, it's categorized as an "active deterrence" feature.
Can the red and blue lights be disabled?
Yes, the light and sound alarm features can typically be configured or disabled through the camera's settings via the web interface or the mobile application. You have control over when and how these deterrence features activate.
Does this camera work with NVRs from other brands?
This camera supports ONVIF (Profile S/Profile G/Profile T) and CGI protocols, which means it should have basic compatibility with many third-party NVRs. However, for full access to advanced AI features like SMD 3.0 and intelligent search, it is recommended to use a Dahua Smart NVR.
How long can the SD card record for?
The recording duration on the 256 GB Micro SD card depends on several factors, including the video resolution, compression (H.265 vs. H.264), frame rate, and the amount of motion detected. For continuous recording, 256 GB can typically store several days to a week or more of footage. Event-based recording will significantly extend this duration.
What makes this camera different from a standard fixed-focal camera?
The key differentiator for this WizSense camera is its integrated AI capabilities, specifically Smart Motion Detection (SMD 3.0) for accurate human/vehicle classification and active deterrence features (siren and red/blue lights). Standard fixed-focal cameras typically offer basic motion detection and recording without these advanced intelligent functions.
Will the siren and lights activate automatically?
Yes, if configured, the siren and lights will automatically activate when a defined intelligent event occurs, such as intrusion or tripwire detection of a human or vehicle. You can customize the rules for when these deterrence actions are triggered.

Summary Recommendation
-
Choose the Newer Model (DH-IPC-HDW3549H-AS-PV-S3) if:
- You require higher resolution (5 MP) for more detailed image capture.
- You need the benefit of dual MICs for potentially clearer two-way audio.
- You want the latest iteration of Dahua's Smart Motion Detection with SMD 3.0 for improved accuracy and fewer false alarms.
- You specifically need both warm light and IR LED illumination, although the older model also offers dual illumination with warm light and IR as a combined feature.
-
The Older Model (IPC-HDW3449H-AS-PV-S2) might still be suitable if:
- A 4 MP resolution is sufficient for your monitoring needs, as it still provides good image quality.
- Cost-effectiveness is a primary concern, as older models are often available at a lower price point.
- The slightly different DORI distances (which are quite similar to the newer model) are acceptable for your deployment.
- You don't specifically require dual built-in microphones, and a single mic is adequate.
- The existing SMD Plus features meet your intelligent detection requirements.
