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
This camera intelligently toggles between IR and warm light depending on what’s happening in the scene. IR mode runs quietly in the background for discreet nighttime coverage. When a person or vehicle is detected, warm light activates — giving you vivid color footage exactly when it matters most, then switches back to IR to reduce unnecessary brightness.
SMD 4.0 (Smart Motion Detection)
SMD 4.0 filters out irrelevant motion by focusing on human and vehicle shapes. It significantly reduces false alarms caused by animals, weather, or foliage, and works well even in low-light or nighttime conditions thanks to optimized AI training.
AcuPick Search
Instead of scrubbing through hours of recordings, AcuPick lets you quickly find specific moments based on what or who you’re looking for. It uses deep learning to match appearance data and works in sync with compatible back-end systems like Dahua NVRs.
AI Scene Self-Adaption (SSA)
Lighting conditions can vary drastically throughout the day. SSA uses AI to automatically adjust image parameters like contrast and exposure to ensure optimal clarity in each unique scene — especially helpful in outdoor settings with moving shadows or headlight glare.
Active Deterrence System
Beyond just detecting motion, this camera acts. Flashing red/blue lights and customizable audio alerts start the moment a threat is detected. This visible and audible response discourages trespassers before a crime can occur — ideal for protecting unattended areas or vulnerable perimeters.
Smart App & NVR Integration
Easily access live and recorded footage via the DMSS mobile app. The camera supports real-time alerts, remote talkback, event filtering, and one-tap disarming — perfect for both DIY users and professionals managing multiple sites.
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.
More About AcuPick - Smart Video Search with Precision AI
Dahua’s AcuPick technology revolutionises video surveillance by using advanced AI to pinpoint people or vehicles across recorded footage with remarkable speed and accuracy. Instead of scrubbing through hours of video manually, AcuPick enables users to filter footage by specific targets, drastically cutting down search times and boosting operational efficiency. Integrated into a range of Dahua cameras (including TiOC series) and compatible NVRs, AcuPick delivers a seamless and intelligent search experience.
Highlights of AcuPick:
AI-Driven Precision:
AcuPick leverages intelligent algorithms to differentiate between human and vehicle activity, refining search results to what truly matters.
Smart Filtering:
Search footage using key attributes like clothing colour or vehicle type—no need to know the exact time an incident occurred.
Instant Video Recall:
With just a few clicks, users can zero in on critical moments, improving response times and streamlining investigations.
False Alarm Reduction:
By filtering out irrelevant motion, AcuPick helps reduce nuisance alerts, leading to more reliable monitoring.
Flexible Deployment:
Whether through Dahua's smart cameras or NVR integration, AcuPick fits into a wide range of security setups.
Practical Applications:
-
Retail & Offices: Track customer flow or monitor for unauthorized access.
-
Car Parks & Garages: Instantly retrieve footage of accidents or suspicious activity.
-
Public Spaces: Quickly find persons of interest using visual identifiers.
-
Residential Estates: Enhance safety by identifying vehicle movements or visitors.
AcuPick transforms surveillance from reactive monitoring to proactive intelligence, saving time while elevating security across the board.
Q&A
Q: Can this camera record in color at night?
Yes. Thanks to Smart Dual Illumination, it records in full color when motion is detected using the warm light, and switches back to IR when not needed.
Q: Can the light and siren deterrent be disabled?
Absolutely. Both can be toggled manually or triggered automatically through motion rules. You can also set quiet hours or disarm them entirely via the mobile app.
Q: How loud is the built-in speaker?
It’s loud enough to serve as a real deterrent in most outdoor environments — suitable for alerting intruders or communicating through two-way talk up to several meters away.
Q: Does this camera work with non-Dahua NVRs?
Yes, it's ONVIF compliant (Profiles S, G, T), so it will work with most third-party NVRs that support ONVIF standards, though AI features may be limited.
Q: How long will footage stay on a 512GB microSD card?
This depends on settings. With AI H.265 compression and motion-based recording, it could store several weeks of footage. Higher resolution or continuous recording will reduce storage time.
Q: What’s the difference between this and a PRO model?
This model focuses on smart motion and deterrence. PRO versions typically add advanced analytics (e.g., facial recognition, people counting) and higher-grade components for enterprise use.
Q: Will the lights and siren go off automatically when motion is detected?
Yes. You can set the camera to trigger both the red/blue strobe and audio alarm as soon as human or vehicle movement is detected in a defined area.
Q: Can I install this indoors?
Technically yes, but its deterrence features (lights and siren) are designed for outdoor use. Indoors, it’s better suited for garages or warehouses where those features still serve a purpose.
