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
WizSense AI Features Explained
The DH-PTZ1A225-HNR-XA is part of Dahua's WizSense series, which leverages a neural network processor to bring advanced deep-learning algorithms to your security system. This means the camera is not just recording; it's intelligently analyzing scenes. The primary focus is on accurately detecting and classifying humans and vehicles, significantly reducing false alarms that plague traditional motion detection systems. This precision allows your security system to focus on genuine threats, improving response times and reducing unnecessary alerts.
Intelligent Auto-Tracking in Action
The auto-tracking feature is a game-changer for monitoring dynamic environments. When an object (human or vehicle) is detected moving within a pre-defined area, the camera can automatically adjust its pan, tilt, and zoom to keep the object centered and in clear view. This is incredibly useful for covering large perimeters, tracking suspicious individuals in real-time, or monitoring activity in a busy intersection. It ensures that crucial moments are captured even if the subject moves beyond the initial field of view.
Perimeter Protection for Enhanced Security
Beyond simple motion detection, perimeter protection sets up virtual tripwires or intrusion zones. What makes it powerful is its ability to differentiate between humans and vehicles versus minor disturbances like animals, rain, or swaying trees. This intelligent filtering drastically cuts down on false alarms, allowing security personnel to prioritize and respond only to events that genuinely matter, making your surveillance system far more efficient and reliable.
Starlight Technology for Superior Low-Light Performance
Many cameras struggle to provide clear images in dim light, often switching to black and white or producing grainy footage. Dahua's Starlight Technology, however, excels in challenging low-light conditions, capturing vibrant color details down to an impressive 0.005 Lux. This capability is critical for identifying specific details like clothing colors or vehicle models during dusk, dawn, or even moonlight, which might otherwise be lost in standard black and white infrared footage.
Video Metadata for Smart Search and Analysis
The video metadata function is a powerful analytical tool. The camera doesn't just record video; it intelligently extracts and tags information about detected objects. This includes classifying them as motor vehicles, non-motor vehicles, human faces, or human bodies, and even capturing high-quality snapshots. This rich metadata allows for highly efficient post-event searching, enabling users to quickly filter through hours of footage to find specific events, such as all instances where a "red car" or a "person wearing a hat" was detected.
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, thanks to its Starlight Technology, this camera can capture color details in very low-light conditions (down to 0.005 Lux). In complete darkness, its powerful 150m IR illuminators will provide clear black and white footage.
Q: Does this camera have a built-in siren or flashing lights for deterrence?
A: No, this specific model (DH-PTZ1A225-HNR-XA) does not include a built-in siren or red/blue strobe lights for active deterrence. Its focus is on intelligent monitoring, tracking, and advanced detection.
Q: How long can the SD card recording last?
A: The camera supports a microSD card up to 256GB. The actual recording duration depends on factors like resolution, frame rate, compression (H.265+ is highly efficient), and the amount of motion detected. For continuous recording, a 256GB card can typically store several days to over a week of footage, but this can extend significantly with motion-triggered recording.
Q: Can this camera integrate with NVRs from other brands?
A: Yes, the camera supports ONVIF (Profile S/Profile G) and CGI protocols, which are industry standards for IP camera interoperability. This means it can generally be integrated with NVRs and VMS (Video Management System) software from other manufacturers that also support these standards. However, for full functionality and to leverage all AI features, integration with a Dahua AI NVR is recommended.
Q: What is the main difference between this WizSense model and a standard PTZ camera?
A: The core difference lies in the "WizSense" intelligent functions, powered by a neural network processor. This camera goes beyond basic motion detection by accurately classifying objects (humans, vehicles) and filtering out false alarms, offering advanced features like video metadata and more reliable perimeter protection compared to standard PTZ cameras.
Q: Can I access the camera feed and control the PTZ functions from my phone?
A: Yes, Dahua provides mobile applications like DMSS and Easy4ip for both iOS and Android devices, allowing you to view live feeds, control the pan/tilt/zoom, and receive push notifications from the camera remotely.
Q: Is it difficult to set up the auto-tracking and perimeter protection features?
A: While initial setup requires accessing the camera's web interface or connecting to a Dahua NVR/VMS, Dahua aims for "simple configuration" with its WizSense series. The interfaces are generally user-friendly, and there are guides available to help set up these advanced AI features.
