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 Explained
The Smart Dual Illuminators feature is a standout technology that optimizes night vision and reduces light pollution. Typically, the camera uses its infrared (IR) illuminators at night, providing a clear black and white image while being discreet. However, when a person or vehicle enters the monitored area, the camera intelligently switches on its warm white lights. This transition allows the camera to capture full-color video of the event, providing much richer detail, like clothing color or vehicle specifics, which is crucial for identification. Once the detected target leaves the area, the warm light automatically turns off, and the IR illuminator resumes, minimizing unnecessary light output and maintaining a low-profile surveillance presence. This system provides superior evidence capture without constant, bright illumination.
Enhanced Smart Motion Detection (SMD 3.0)
SMD 3.0 is an intelligent algorithm that elevates motion detection beyond basic pixel changes. It's specifically trained to differentiate between human and vehicle targets and other common motion triggers, such as falling leaves, animals, or changes in lighting. This means you'll receive significantly fewer false alarms, allowing you to focus only on alerts that truly matter. By accurately categorizing targets, the camera provides more precise notifications, ensuring that your attention is drawn only to relevant events, making your security monitoring much more efficient and less intrusive.
Active Deterrence: More Than Just Recording
The Active Deterrence capabilities of this camera offer a proactive layer of security. Beyond simply recording an event, the camera is equipped to respond directly to detected intrusions. When the perimeter protection triggers an alarm (e.g., tripwire or intrusion by a human or vehicle), the built-in loud siren activates, accompanied by flashing red and blue LED lights. This immediate, attention-grabbing combination is designed to startle and deter potential intruders on the spot, often preventing an incident from escalating further. The ability to customize the voice alerts also allows for tailored warnings, making the deterrence even more effective for specific situations.
Seamless Integration and Management
This Dahua camera is designed for seamless integration with various security platforms. It supports ONVIF (Profile S/G/T), allowing it to work with a wide range of Network Video Recorders (NVRs) from different manufacturers, though for optimal performance and AI feature utilization, pairing it with a Dahua WizSense NVR is recommended. Management software like Smart PSS, DSS, and the DMSS mobile app (for iOS and Android) provide comprehensive control. From the mobile app, you can view live feeds, review recorded footage, receive push notifications for alarms, and even engage in two-way conversations through the camera, offering complete control over your security system from anywhere.
Q&A Section
Q: Can this camera record in color at night?

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 an outdoor environment. You can upload custom voice messages for the siren feature to suit your specific needs.
Q: Can the red and blue flashing lights be disabled?
A: Yes, the active deterrence features, including the lights and siren, can be configured and enabled/disabled through the camera's settings via the management software or mobile app.
Q: Does this camera work with NVRs from other brands?
A: Yes, it supports ONVIF (Profile S/G/T), which means it can generally work with NVRs from other manufacturers that also support ONVIF. However, for the full range of AI features and optimal compatibility, it's recommended to pair it with a Dahua WizSense NVR.
Q: How much recording time can I expect with a 256GB SD card?
A: The recording time depends on several factors, including the resolution, frame rate, compression (H.265+ is very efficient), and the amount of motion detected. A 256GB card can typically store several days to weeks of event-based or continuous recording, but this can vary significantly.
Q: What makes this "WizSense" camera different from a standard security camera?
A: WizSense cameras use advanced deep learning AI algorithms, specifically focusing on human and vehicle detection. This means it's much better at differentiating between real threats and false alarms (like animals or environmental changes) compared to standard motion detection, providing more accurate alerts and more relevant recordings.
Q: Will the siren and lights activate automatically when motion is detected?
A: The siren and lights are linked to the camera's "Perimeter Protection" features (intrusion and tripwire detection for humans and vehicles). If these intelligent events are enabled and a person or vehicle triggers them, the active deterrence will activate automatically according to your settings.
Q: Is there a subscription required to use any of the features?
A: No, the core features of this camera, including smart detection, active deterrence, two-way talk, and local SD card recording, do not require any ongoing subscriptions. Remote access through the DMSS app is also free.
