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 Explained
The Smart Dual Light feature is designed for efficient and effective night surveillance. Typically, the camera uses its invisible IR illuminators at night to capture clear black and white video without causing light pollution. However, when a human or vehicle is detected within the monitoring area, the camera automatically switches on its warm white light. This transition allows the camera to capture a full-color video of the event, providing richer details like clothing color or vehicle make, which are crucial for identification. Once the detected target leaves the area, the warm light turns off, and the camera reverts to IR mode, minimizing unnecessary light emission and saving power. This intelligent system ensures you get critical full-color details only when they matter most.
SMD 4.0: Beyond Basic Motion Detection
SMD 4.0 (Smart Motion Detection) represents a significant leap from traditional motion detection. Instead of triggering alarms for every movement, SMD 4.0 employs advanced deep learning algorithms to differentiate between humans and vehicles and other moving objects like animals, swaying trees, or falling leaves. This drastically reduces false alarms, allowing you to focus on genuine threats. When combined with a Dahua AI NVR, the Quick Pick feature further enhances efficiency, enabling you to swiftly locate and review human and vehicle targets from event recordings, prioritizing the most relevant clips.
Active Deterrence: Stopping Threats Before They Escalate
The IPC-PDW3849-A180-AS-PV isn't just about recording; it's about actively preventing incidents. Its sound and light alarm system is a powerful deterrent. Upon detecting an intrusion or tripwire event, the camera can automatically activate its highly visible red and blue flashing lights and a loud siren. This immediate and attention-grabbing response often scares off potential intruders before they can cause harm or damage. The camera comes with multiple pre-recorded voice alerts, and you can even upload customized voice messages, allowing for tailored warnings or greetings in specific scenarios.
EPTZ: Focus on What Matters
EPTZ (Electronic Pan, Tilt, Zoom) is an intelligent feature that works in conjunction with the camera's smart alarm functions. When an intelligent alarm (like intrusion or tripwire) is triggered, the EPTZ capability allows the camera to electronically zoom in and track the detected human or vehicle target. This provides a detailed close-up of the event while simultaneously maintaining the wide, panoramic view. This dual perspective is invaluable for understanding the context of an incident and gathering precise details about the target.
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
Q: Can this camera record in color at night?
A: Yes, it can. While it uses invisible IR light for standard nighttime monitoring (in black and white), its Smart Dual Light feature automatically turns on a warm white light when a human or vehicle is detected, allowing it to capture clear, full-color video of the event.
Q: How loud is the built-in speaker for the siren and two-way talk?
A: The speaker is designed to be loud enough for effective active deterrence and clear two-way communication in most outdoor environments. Its volume is sufficient to deliver audible warnings and allow for conversation.
Q: Can the red and blue flashing lights and siren be disabled?
A: Yes, these active deterrence features can be configured or disabled through the camera's settings via the management software or mobile app, allowing you to tailor their activation based on your needs.
Q: Is this camera compatible with NVRs from other brands?
A: This camera supports ONVIF (Profile S/Profile G/Profile T) and CGI, which are industry standards for IP camera interoperability. While it's designed to work best with Dahua NVRs, especially for advanced AI features like Quick Pick, it should generally be compatible with other ONVIF-compliant NVRs for basic recording and live viewing.
Q: How long can the 256 GB Micro SD card record for?
A: The recording duration on a 256 GB Micro SD card depends on factors like video quality (resolution, frame rate), compression (H.265 vs. H.264), motion activity, and continuous versus event-based recording. With H.265 compression and motion-activated recording, it can typically store several days to weeks of footage.
Q: What is the main difference between this model and a "Pro" version of a Dahua camera?
A: "Pro" versions often include higher-grade components, more advanced AI algorithms, additional connectivity options (e.g., more alarm/audio ports, higher bandwidth), enhanced low-light performance (e.g., Starlight+), and sometimes more robust housing materials for extreme environments. This model is a feature-rich WizSense camera, balancing performance with cost-effectiveness for most common applications.
Q: Will the siren and lights activate automatically, or do I have to manually trigger them?
A: The siren and lights can be configured to activate automatically when specific alarm events are detected, such as intrusion or tripwire events from the camera's intelligent features (Perimeter Protection, SMD 4.0). You can also manually trigger them through the mobile app.
