Product SKU: DH-IPC-HDW3849HP-AS-PV-0280B-S3
Product Overview
Combining active deterrence, full-colour night vision, and AI-powered detection in a single turret housing, the Dahua DH-IPC-HDW3849HP-AS-PV-0280B-S3 is built for eave, soffit, and wall mounting at locations where passive recording alone is not enough. This TiOC 2.0 camera uses a 1/2.8″ CMOS sensor to capture 3840×2160 footage at up to 30fps, backed by dual illuminators that provide up to 30m of IR or full-colour warm white coverage depending on operating mode. When AI-confirmed human or vehicle movement is detected, the camera responds automatically with red and blue strobe lights and a 110dB siren, issuing an immediate on-site warning without waiting for human intervention. Built-in dual microphones and a speaker enable two-way audio communication for remote verbal challenges via the DMSS app or a connected Dahua NVR. SMD 3.0 deep learning filters out animals, foliage, and lighting changes so that deterrence and alert responses are reserved for genuine events. IP67 weatherproofing and onboard MicroSD storage up to 256GB complete the package.
Key Capabilities
TiOC 2.0 Three-in-One Architecture
Full-colour recording, SMD 3.0 AI detection, and active deterrence operate as an integrated system rather than separate components. When AI confirms a human or vehicle, the camera responds instantly with strobe and siren without relying on an external alarm panel or monitoring station.
Dual Illuminators with Automatic Mode Switching
IR LEDs handle low-profile background monitoring while warm white LEDs activate for full-colour visibility up to 30m when a detection event occurs. Illumination mode can also be set to full-colour always-on or IR-only, giving installers flexibility to match the site’s monitoring requirements.
8MP Ultra HD at 30fps
3840×2160 resolution at up to 30fps delivers footage with sufficient detail for facial recognition at close range and vehicle identification within the camera’s DORI recognition range of 34m. Smart H.265+ compression keeps file sizes manageable without sacrificing image quality.
Active Deterrence: Strobe and 110dB Siren
Red and blue flashing strobe lights combined with a siren rated at up to 110dB create a visible and audible confrontation with potential intruders. Custom audio files can be uploaded via the web interface, allowing site-specific verbal warnings to play automatically on alarm trigger.
SMD 3.0 Human and Vehicle Classification
Deep learning algorithms running on the camera’s processor classify motion events as human, vehicle, or other in real time. Notifications, recordings, and deterrence responses are only triggered for human and vehicle classifications, removing nuisance alerts from animals, insects, and foliage movement.
Two-Way Audio with Dual Built-in Microphones
Dual built-in microphones and a built-in speaker allow real-time two-way voice communication between the camera and anyone within its field of view. Security personnel or property owners can issue verbal challenges remotely via the DMSS app or a connected Dahua NVR without being on site.
Best For
- Residential Driveways and Front Entries: The 2.8mm fixed lens covers a 107° horizontal field of view, making it well suited to monitoring vehicle approaches and pedestrian entries at residential properties where wide coverage at close to mid range is the priority.
- Retail Frontages and Shopfront Overhangs: Full-colour 24/7 imaging at 8MP captures legible detail of customers and vehicles outside business premises, supporting both loss prevention and liability documentation after incidents.
- Defined Perimeter Zones Requiring Instant Response: AI tripwire and intrusion detection with human/vehicle filtering allows the camera to monitor virtual boundary lines and respond automatically with strobe and siren when a confirmed breach occurs.
- Standalone Sites Without a Central Recorder: MicroSD storage up to 256GB allows the camera to record independently at locations where cabling to a central NVR is impractical, such as remote outbuildings or temporary installations.
- After-Hours Business Premises with Remote Monitoring: Two-way audio and remotely triggered deterrence via the DMSS app allow operators to challenge intruders and activate alarms from anywhere, making this suitable for sites managed after hours without on-site staff.
Why Choose the DH-IPC-HDW3849HP-AS-PV-0280B-S3
Most 8MP turret cameras record what happens. The DH-IPC-HDW3849HP-AS-PV-0280B-S3 is designed to intervene before an incident progresses. The TiOC 2.0 platform links AI detection directly to on-camera deterrence hardware, meaning the strobe and 110dB siren can fire within seconds of a confirmed human or vehicle detection without any external controller. The dual illuminator system keeps the camera operating quietly in IR mode during normal periods and only activates warm white lighting and deterrence when a genuine event is confirmed by SMD 3.0. This reduces unnecessary disturbance and conserves the deterrence response for situations that warrant it. True WDR handles high-contrast scenes at entry points, and AI H.265 compression manages storage efficiently. For installers and end users sourcing through Security Wholesalers, the DH-IPC-HDW3849HP-AS-PV-0280B-S3 delivers a level of automated response that a standard IP turret camera simply cannot match, without the complexity of integrating separate alarm hardware.
Buyer Decision Tips
Buyer Tip: The fixed 2.8mm lens provides a 107° horizontal field of view, which is well matched to wide coverage at entry points, eaves, and shopfronts. If your site requires identification of faces or number plates at distances beyond 15-20m, a narrower focal length fixed lens or a varifocal model will deliver better detail at range. The DORI recognise distance for this model is confirmed at 34m, which sets a practical upper limit for identification tasks.
Buyer Tip: Active deterrence is only as effective as the detection zones configured around it. Before deploying the strobe and siren on automated AI triggers, define intrusion zones carefully within the camera’s web interface or your Dahua NVR to exclude public footpaths, neighbouring driveways, and areas with heavy foliage. Poorly scoped zones will cause deterrence events to fire on non-threatening movement, reducing confidence in the system and increasing maintenance calls.

Ideal Use Cases
Home Driveway and Gate Monitoring
The 107° wide-angle coverage from the 2.8mm lens captures the full width of most residential driveways and gate entries. When AI detects a person or vehicle after dark, dual illuminators switch to full-colour warm light and the deterrence system activates before any approach to the property reaches the door.
Retail Shopfront and Loading Areas
8MP full-colour imaging captures readable vehicle and facial detail outside retail premises during and after trading hours. The strobe and siren deter after-hours intrusion attempts without requiring a security guard on site, while two-way audio allows remote verbal engagement with anyone in the camera’s view.
Perimeter Fence Lines and Access Gates
AI tripwire and intrusion zone detection allow virtual boundaries to be drawn across fence lines or gate openings. SMD 3.0 ensures that only confirmed human or vehicle crossings trigger alerts and deterrence responses, keeping false alarm rates low even in locations with animal movement or wind-affected vegetation.
Outbuildings and Remote Standalone Deployments
With MicroSD recording up to 256GB, this camera operates independently without a central NVR. Sheds, garages, rural machinery storage, and construction site compounds can be monitored and protected with active deterrence without the cost or complexity of running additional recorder infrastructure.
Small Commercial Premises Monitored Remotely
DMSS app integration allows business owners and security operators to receive push alerts, view live footage, trigger the siren manually, and conduct two-way audio conversations remotely. This supports after-hours monitoring of small businesses, warehouses, and trade yards without a full monitoring centre arrangement.
Choosing the Right Model
- Choose this model if: You need a self-contained outdoor turret camera with full-colour night vision, AI-triggered strobe and siren deterrence, two-way audio, and SMD 3.0 human/vehicle detection in a single IP67-rated unit with a wide 2.8mm field of view.
- Choose a different model if: Your site requires a varifocal lens for adjustable framing during installation, illumination range beyond 30m for long open areas, or if active deterrence features are not required and a standard full-colour turret would meet the brief at a lower cost.
FAQs
- What does TiOC 2.0 mean in practical terms for this camera?
TiOC stands for Three-in-One Camera and refers to the integration of full-colour recording, AI-based event detection, and active deterrence hardware in a single device. Version 2.0 refines the AI detection accuracy and response logic compared to the original TiOC. Rather than simply recording an incident, this camera can issue an immediate on-site response via strobe lights and siren the moment AI confirms a human or vehicle detection. - Does the camera produce full-colour footage all night, or only when triggered?
Both modes are available and configurable. In smart illumination mode, the camera uses IR LEDs for discreet continuous monitoring and automatically switches to warm white LEDs for full-colour imaging when a detection event occurs. Alternatively, it can be set to full-colour always-on mode where warm white light operates continuously throughout the night, or IR-only mode where colour imaging is disabled. - How accurate is SMD 3.0 at filtering out animals and environmental triggers?
SMD 3.0 uses deep learning running on the camera’s onboard processor to classify detected motion as human, vehicle, or other in real time. In practice this means cats, dogs, birds, blowing foliage, and changes in ambient lighting are classified as non-human and non-vehicle, and will not trigger alert notifications or the active deterrence response. Only confirmed human and vehicle classifications activate these functions, significantly reducing nuisance alert rates compared to standard motion detection cameras. - Can the strobe and siren be activated manually rather than automatically?
Yes. In addition to automatic activation on AI detection events, the strobe and siren can be manually triggered through the camera’s web interface, via a connected Dahua NVR, or through the DMSS mobile app. This gives operators or property owners the option to issue a deterrence response at their own discretion when reviewing live footage, independent of any automated AI trigger. - What is the maximum MicroSD card size supported, and is the card slot accessible without dismounting the camera?
The camera supports MicroSD cards up to 256GB for local onboard storage. Recording can operate continuously or on event-triggered motion. The MicroSD card slot location varies by installation orientation, and in most cases the junction box cover will need to be opened to access it. It is best practice to insert the card before final installation to avoid the need to dismount the camera later. - Is the two-way audio genuinely built in, or does it require an external microphone or speaker?
Two-way audio on the DH-IPC-HDW3849HP-AS-PV-0280B-S3 requires no external components. The camera has dual built-in microphones for audio capture and a built-in speaker for audio output, enabling real-time voice communication in both directions via the DMSS app or a compatible Dahua NVR. The audio input/output ports on the camera are available for connecting external microphones or speakers if required, but the built-in hardware is fully functional without them. - What PoE standard does this camera require, and what is the recommended cable run?
The camera is powered via PoE using standard Cat5e or Cat6 cable. The maximum recommended cable run from a PoE switch or PoE NVR port to the camera is 100 metres. Runs exceeding this distance can result in insufficient power delivery or network instability. For longer distances, a PoE extender or a PoE midspan injector placed along the cable run can extend reach beyond the standard 100m limit. - Is this camera compatible with Dahua NVRs, and where can I get help selecting a matching recorder?
The DH-IPC-HDW3849HP-AS-PV-0280B-S3 is fully compatible with Dahua NVRs that support TiOC 2.0 and WizSense AI functions, allowing active deterrence events, SMD 3.0 alerts, and two-way audio to be managed from a central recorder interface. It also integrates with the DMSS mobile application for remote access. Security Wholesalers can assist in identifying a suitable Dahua NVR to pair with this camera based on channel requirements, storage capacity, and AI feature support.
