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 features Dahua’s intelligent Smart Dual Light system, which seamlessly switches between infrared (IR) night vision and warm white LED light based on scene activity. When no motion is detected, the camera stays in discreet IR mode to conserve energy and avoid unnecessary lighting. As soon as a person or vehicle enters the monitored area, the warm light activates automatically, enabling full-color recording. This results in clearer, more useful footage during critical events — for instance, capturing clothing colors, car types, or facial features. After the activity ends, the camera reverts back to IR mode. This dynamic lighting system reduces light pollution, saves power, and enhances evidence collection.
SMD 4.0 – Smart Motion Detection
The fourth-generation Smart Motion Detection (SMD 4.0) uses deep learning to dramatically improve motion detection accuracy. Traditional cameras often trigger false alarms from irrelevant movement — such as trees swaying or pets passing by. SMD 4.0 filters these out by recognizing only human and vehicle motion with much higher precision, even in low light or challenging conditions. Compared to previous versions, it offers extended detection range, better target classification, and higher event confidence levels. For users managing alerts on mobile apps or NVRs, this means fewer interruptions and much more actionable intelligence.
AcuPick – AI-Powered Target Search
AcuPick is a powerful forensic tool that allows you to select a person or vehicle from a snapshot or live view, and instantly search through hours or days of recorded footage to locate every appearance of that target. It works in conjunction with supported Dahua NVRs and uses AI-powered metadata to match movement, clothing, or vehicle types. This drastically reduces investigation time — for example, in retail theft, missing persons, or access control breaches. AcuPick is especially helpful for property managers, security teams, and business owners who need fast access to relevant footage without manual scrubbing.
AI Scene Self-Adaption (SSA)
AI Scene Self-Adaption is Dahua’s deep learning-based image optimization system. Instead of relying on fixed exposure settings, SSA continuously adjusts image parameters — such as brightness, contrast, and dynamic range — based on real-time scene conditions. Whether the camera is facing harsh sunlight, headlights at night, or low-light environments like alleys and warehouses, SSA enhances visibility and color accuracy. It’s ideal for installations where lighting is unpredictable, and it ensures the footage is always usable — without manual configuration. For DIY users, this means clearer video out of the box. For professionals, it reduces installation time and post-tuning.
Active Deterrence with Lights & Audio
Built-in red and blue flashing lights combined with a loudspeaker make this camera a powerful deterrent tool. When a pre-defined rule is triggered — like someone crossing a virtual boundary — the camera can flash warning lights and play audio alerts to scare off intruders. The speaker supports both default and custom messages, allowing personalized warnings like “You are under surveillance” or “Security has been notified.” This two-layered deterrent capability is especially effective in deterring theft, trespassing, and loitering before crimes escalate. It’s perfect for parking lots, construction sites, backyards, and other at-risk areas.
Mobile App & NVR Integration
This model integrates seamlessly with Dahua’s mobile app (DMSS) and Smart NVRs, enabling real-time alerts, remote playback, two-way audio, and live streaming. Users can manage push notifications, disarm alarms temporarily with One-Tap Disarming, or search SMD/AcuPick events on the go. It also supports ONVIF (Profiles S, G, T), making it compatible with third-party NVRs and VMS systems. For DIY homeowners, this means plug-and-play convenience with mobile control. For security integrators and businesses, it ensures flexibility in hybrid system designs and centralized management.
Flexible Storage Options
The camera supports local storage via microSD card (up to 512 GB), as well as NAS, FTP/SFTP backups, and NVR integration. This allows users to record directly on the camera for smaller installations or use centralized recording for larger deployments. Paired with intelligent features like smart search and event filtering, footage is not only recorded — it’s organized and easy to access. For customers concerned about subscription fees or offsite bandwidth usage, onboard storage offers a cost-effective, private solution.
Reliable Outdoor Performance
Built with a sturdy metal housing and IP67 rating, this camera is designed to endure tough environments — including rain, dust, humidity, and extreme temperatures (from –30°C to +60°C). Whether installed on a remote gate, exposed wall, or metal pole, it offers consistent performance and minimal maintenance. Combined with features like voltage protection and surge resistance, it’s a reliable long-term investment for both residential and commercial outdoor security setups.
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 Seach 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.

Q&A
Q: Can this camera record in color at night?
Yes. The Smart Dual Light feature activates warm white LEDs when motion is detected, allowing for full-color night recording.
Q: Can the siren and lights be turned off?
Yes. You can disable them or set them to only trigger during specific hours, areas, or alarm rules.
Q: Does this work with third-party NVRs like Hikvision or UniFi?
Yes, it supports ONVIF (Profiles S/G/T) for compatibility with many third-party systems, though advanced features may be limited.
Q: How loud is the built-in speaker?
The speaker is suitable for outdoor environments and can deliver clear, audible voice messages or alarms within 10–15 feet.
Q: How long can the microSD card store recordings?
That depends on resolution and bitrate settings, but a 512GB card can store up to several weeks of motion-triggered 8MP video.
Q: What’s the difference between this and the PRO version (DH-IPC-HDW3849H-AS-PV-PRO-ANZ)?
The PRO version generally offers better light sensitivity, longer illumination range, improved chipset performance, and sometimes faster response time or deeper NVR integration.
Q: Will the siren go off automatically when someone enters the area?
Yes, if configured. You can use IVS rules or SMD zones to trigger both the siren and the strobe light automatically on intrusion.
