Key Capabilities
TiOC 2.0 Three-in-One Technology
Integrates full-colour monitoring, AI-powered detection, and active deterrence into a single device. This reduces the need for separate alarm components and delivers an immediate, automated response to detected intrusions without requiring manual intervention.
8MP Ultra HD Imaging
Captures video at 3840×2160 resolution and up to 30fps, delivering the fine detail needed for facial and vehicle identification. Evidence-grade footage is particularly valuable for insurance claims, investigations, and post-incident reviews.
Dual Illuminators with Smart Switching
IR and warm white LEDs can operate independently or switch automatically based on detection events. This allows discreet background monitoring with IR and switches to full-colour visibility when a person or vehicle is detected, up to 30m.
Active Deterrence — Strobe & Siren
Red and blue flashing lights combined with a built-in siren up to 110dB confront potential intruders the moment an AI event is triggered. This visible and audible response can deter threats before any physical breach occurs.
SMD 3.0 Smart Motion Detection
Deep learning algorithms accurately distinguish humans and vehicles from animals, foliage, and other irrelevant movement. This greatly reduces nuisance alerts, ensuring that notifications and recordings are only triggered by genuine security events.
Two-Way Audio with Dual Microphones
Built-in dual microphones and a speaker enable real-time two-way communication with anyone in the camera’s field of view. Security personnel or homeowners can issue verbal warnings or instructions remotely via a connected app or NVR.
Best For

- Retail & Shopfront Surveillance: Full-colour 24/7 imaging and 8MP resolution provide detailed footage of customers and vehicles outside business premises, supporting both security and liability documentation.
- High-Risk Perimeter Zones: AI tripwire and intrusion detection with human/vehicle classification makes this camera well suited to monitoring boundaries, gates, and access-controlled areas where precision alerting is critical.
- Standalone Deployments Without NVR: Onboard MicroSD storage up to 256GB allows the camera to record independently, making it practical for locations where running cable to a recorder is not feasible.
- Small Business & Light Commercial Sites: The combination of deterrence, AI detection, and two-way audio provides enterprise-level capabilities at a price point accessible for smaller installations.
Why Choose the DH-IPC-HDW3849HP-AS-PV-0280B-S3
Standard IP cameras record what happens — this camera actively works to prevent it. While a basic 8MP turret will capture an incident in detail, it offers no real-time response. The DH-IPC-HDW3849HP-AS-PV-0280B-S3 adds strobe alarms, a 110dB siren, two-way audio, and AI-triggered illumination to create a genuinely proactive security device. SMD 3.0 ensures that all of these responses are triggered only by confirmed human or vehicle detections, not by passing animals or tree movement. The dual illuminator system means the camera operates quietly in IR mode most of the time and only activates warm light and deterrence features when a real event occurs, conserving power and reducing unnecessary disturbance. For installers and end users sourcing through Security Wholesalers, this model represents a significant step up from conventional cameras in environments where deterrence is as important as recording. True WDR, Smart H.265+ compression, and IP67 weatherproofing round out a well-specified package for both indoor and outdoor use.
Buyer Decision Tips
Buyer Tip: The 2.8mm fixed lens provides a wide 107° horizontal field of view, making it best suited to areas where width of coverage matters more than long-distance detail — such as driveways, corridors, or shopfronts. If your primary need is to identify faces or number plates at distance beyond 15–20m, consider a narrower focal length model.
Buyer Tip: When using the active deterrence features, configure the AI detection zones carefully within the camera’s web interface or via your Dahua NVR. Poorly defined detection zones can result in the strobe and siren activating for non-threatening movement such as pedestrians on public footpaths adjacent to your property.

FAQs
- What does TiOC 2.0 mean, and how is it different from a standard IP camera?
TiOC stands for Three-in-One Camera — combining full-colour recording, AI-based detection, and active deterrence in a single unit. Unlike a standard IP camera that only records events, a TiOC 2.0 camera actively responds to detected intrusions with flashing strobe lights and a siren, making it a preventative security tool rather than purely a reactive one. - Can this camera record in colour at night without any external lighting?
Yes. The built-in warm white LED illuminator provides up to 30m of full-colour illumination in complete darkness. In standard monitoring mode, the camera uses IR LEDs for discreet night recording, automatically switching to warm white light when a person or vehicle is detected, or the illumination mode can be set manually. - Does the camera work without a NVR or recorder?
Yes. The camera supports a MicroSD card up to 256GB for local onboard storage, allowing it to record continuously or on motion detection without requiring a connected NVR. This makes it suitable for standalone deployments at locations where a centralised recorder is not installed. - How loud is the built-in siren, and can the alarm sounds be customised?
The built-in siren reaches up to 110dB, which is comparable to a car horn and clearly audible at distance. Alarm audio can be customised — the camera supports uploading custom audio files via its web interface or connected Dahua NVR, allowing you to set specific verbal warning messages in addition to standard alarm tones. - What is SMD 3.0 and how does it reduce false alarms?
Smart Motion Detection 3.0 uses deep learning AI to analyse motion events and classify detected objects as human, vehicle, or other. Only human and vehicle classifications trigger alarm notifications, filtering out false triggers caused by animals, insects, blowing foliage, or changes in lighting. This significantly reduces alert fatigue for both homeowners and monitoring centres. - Is this camera compatible with Dahua NVRs and the DMSS mobile app?
Yes. The DH-IPC-HDW3849HP-AS-PV-0280B-S3 is fully compatible with Dahua NVRs that support TiOC and AI functions, and integrates with the DMSS mobile application for remote live viewing, playback, and alarm push notifications. For purchasing and compatibility advice, Security Wholesalers can assist in matching this camera with a suitable Dahua NVR. - What is the maximum cable run for PoE powering this camera?
As a PoE-powered IP camera, the maximum recommended cable run using Cat5e or Cat6 cable is 100 metres from the PoE switch or NVR to the camera. Exceeding this distance may result in power delivery issues or network instability. For longer runs, a PoE extender or midspan injector can be used. - Can the strobe and siren be triggered manually or only by AI detection?
The active deterrence features can be triggered automatically via AI detection events such as intrusion or tripwire alarms, or activated manually through the camera’s web interface, a connected Dahua NVR, or the DMSS app. This gives operators flexibility in how and when deterrence responses are deployed.
