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: Intelligent Lighting That Adapts
This camera intelligently switches between IR (infrared) and warm white light depending on detected activity. At night, it typically operates in discreet IR mode to remain low-profile. But when a person or vehicle is detected in a predefined zone, the camera activates the warm white light to capture full-color footage — helping identify details like clothing color, vehicle make, or license plates. The light not only enhances visibility but also acts as a subtle form of deterrence, signaling that surveillance is active.
Active Deterrence: Built-In Defense Mechanism
Equipped with flashing red and blue warning lights and a built-in speaker, the camera acts as more than just a passive observer. You can upload custom audio messages or use built-in sounds to warn intruders in real-time. This makes it ideal for environments where you want to prevent crime — not just record it. You can trigger alerts automatically via AI detection or manually via app or NVR interface.
SMD 4.0: Smarter Motion Detection with Less Noise
Smart Motion Detection (SMD) 4.0 uses deep learning to recognize human and vehicle shapes — filtering out irrelevant motion like swaying trees, rain, insects, or pets. This significantly reduces false alarms and saves time when reviewing footage. It also makes the system more reliable for push notifications or automated deterrents.
AcuPick: Rapid Search for Real Targets
AcuPick works in tandem with supported Dahua NVRs to allow users to click on a person or car in the live or recorded footage — and the system will instantly pull up all appearances of that subject across multiple feeds. This eliminates the need for tedious manual scrubbing through timelines. It’s especially useful in multi-camera setups for tracking movement across zones.
AI Scene Self-Adaption (SSA): Always Optimized Video
Lighting conditions constantly change — cloudy skies, backlight from headlights, or interior shadows can degrade image quality. AI SSA continuously adjusts exposure, contrast, sharpness, and other visual settings based on the scene. This ensures that faces, license plates, and motion events are consistently clear, even in complex lighting.
Motorized Vari-focal Lens: Flexible Framing Made Easy
Unlike fixed-lens models, this camera features a motorized 2.7mm–13.5mm zoom lens. Installers and users can remotely adjust the zoom level for wide-angle coverage (ideal for large spaces) or narrow focus (perfect for gates or entry points). This makes the camera adaptable for future needs — no need to replace the device if the scene layout changes.
Full Duplex Two-Way Audio: Real-Time Interaction
With dual microphones and a built-in speaker, you can have live conversations through the camera. This is ideal for visitor screening, delivery instructions, or warding off loiterers. Unlike cameras with only one-way audio, this unit supports clear two-way communication for practical, day-to-day interactions.
Local Storage: Up to 512GB microSD
With support for up to 512GB of local microSD card storage, this camera can operate independently from an NVR, making it suitable for smaller or remote setups. It’s also valuable as a backup in case network connectivity fails — ensuring you never lose critical footage.
ONVIF Compatibility + Multi-Network Protocols
While optimized for Dahua NVRs, this camera also supports ONVIF (Profile S/G/T), making it compatible with most third-party recording systems. Its wide range of network protocols ensures smooth integration into both residential and commercial environments.
Built for the Outdoors: IP67 Weatherproofing
Housed in a sturdy metal-and-plastic shell, this model is built to withstand harsh environments — from dust storms to heavy rain and temperatures from –30°C to 60°C. Whether mounted in sunny driveways or icy warehouse exteriors, it keeps operating reliably year-round.
App & Remote Access: Mobile Monitoring from Anywhere
The DMSS mobile app (iOS and Android) allows users to view live footage, review recordings, control zoom/focus, speak through the camera, or receive real-time push notifications. Whether you’re at home, traveling, or managing a property remotely, you’re always in control.
Enterprise-Grade Cybersecurity
This model includes advanced cybersecurity features such as video and firmware encryption, IP/MAC filtering, account lockout, HTTPS access, and trusted boot protocols. These protections help ensure that the camera and your footage remain secure — an increasingly important consideration in modern surveillance.
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 full color at night?
Yes. With Smart Dual Illumination, it uses warm white light to capture full-color video when motion is detected.
Q: How loud is the built-in speaker for deterrence?
It’s loud enough for outdoor environments, designed to alert intruders or communicate clearly with visitors.
Q: Can the lights and siren be turned off?
Yes. You can control or schedule light and siren triggers through the settings or via a connected NVR or app.
Q: Does this camera work with non-Dahua NVRs?
Yes, it's ONVIF-compliant (Profile S/G/T), so it works with most third-party NVRs, though some AI features may be limited.
Q: How long can recordings be stored on the SD card?
That depends on resolution and frame rate, but a 512GB card typically holds weeks of footage with smart compression (H.265+).
Q: What makes this different from the PRO model?
The PRO model usually includes stronger AI functions, improved hardware, or longer IR ranges — but this S2 version offers excellent features like AcuPick and SMD 4.0 already.
Q: Will the siren and lights activate automatically with motion?
Yes, when configured, the camera can automatically flash lights and play audio when a human or vehicle is detected.
Q: Can I zoom the view remotely?
Yes. The motorized vari-focal lens allows remote zoom and focus adjustments for flexible installation.
