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
Advanced 4G Connectivity for Off-Grid Surveillance
The DH-IPC-HFW3441DG-AS-4G-EAU-B stands out with its integrated 4G module, making it a true plug-and-play solution for locations where traditional wired or Wi-Fi networks are unavailable. Simply insert a 4G SIM card, and the camera can directly connect to the internet, allowing for remote viewing, notifications, and control via your mobile client (DMSS app). This capability eliminates the need for complex network infrastructure, opening up surveillance possibilities for construction sites, remote farms, temporary events, or even mobile applications like monitoring boats. The robust 4G performance ensures consistent streaming and reliable alarm delivery, even in areas with fluctuating network conditions.
Precision Detection with PIR and SMD 3.0
This camera integrates both a Passive Infrared (PIR) sensor and Dahua's advanced Smart Motion Detection 3.0 (SMD 3.0). The PIR sensor detects changes in infrared radiation, primarily human body heat, significantly reducing false alarms caused by environmental factors like wind-blown trees or rain. Complementing this, SMD 3.0 uses deep-learning algorithms to precisely differentiate between humans and vehicles while filtering out irrelevant objects. This combination ensures that you receive highly accurate alerts, focusing only on threats that matter, and minimizing notification fatigue. When an actual human or vehicle intrusion is detected, the camera can trigger its built-in sound and light alarm for immediate deterrence.
Active Deterrence with Sound and Light Alarm
Beyond mere detection, this camera offers an active deterrence mechanism. When a defined alarm event occurs (such as a human crossing a tripwire or intruding into a protected area), the camera can automatically activate its warm light and built-in siren. This sudden burst of light and sound is designed to startle and deter potential intruders on the spot, often preventing an incident from escalating. The warm light also serves a dual purpose by illuminating the scene in full color during an alarm, providing richer visual evidence. This proactive approach adds a crucial layer of security, acting as a visible and audible warning.
Flexible Night Vision with Dual Illumination
The camera features Smart Dual Illumination, offering versatility in night monitoring. In standard low-light conditions, the camera utilizes its IR LEDs for clear black and white images up to 50 meters. However, if an event is detected, or if configured to do so, the camera can switch to its warm light illuminator, providing full-color night vision for up to 30 meters. This allows for better identification of details like clothing color or vehicle make in the dark. The "Smart Illumination" feature ensures that the lighting automatically adjusts to prevent overexposure, delivering balanced and clear images regardless of the ambient light.
Seamless Mobile Integration with DMSS App
Managing your camera on the go is made easy with the Dahua DMSS mobile client (available for iOS and Android). Through this app, you can view live feeds, playback recorded footage, receive instant push notifications for alarm events, and even engage in two-way audio communication with visitors or intruders. The app provides full control over camera settings, alarm configurations, and monitoring of storage status, ensuring you're always connected and in control of your security system, no matter where you are, as long as your camera has a 4G signal.
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
Q1: Can this camera record in color at night?
A1: Yes, this camera features Smart Dual Illumination. While it uses IR (infrared) for black and white night vision by default, it also has a built-in warm light. When an alarm is triggered, or if configured, it can activate the warm light to capture full-color images up to 30 meters, providing more detailed visual evidence.
Q2: How loud is the built-in speaker, and can I customize the sound?
A2: The built-in speaker is designed for effective two-way audio communication and alarm deterrence. While the exact decibel level isn't specified, it's loud enough to be heard clearly for communication and to provide an impactful alarm. The documentation suggests sound and light alarm linkage, implying you can trigger a built-in siren sound. The ability to upload custom sounds is not explicitly mentioned but is often a feature in advanced Dahua models; you would need to check the camera's specific firmware options.
Q3: Can the sound and light alarms be disabled or set to activate only for specific events?
A3: Yes, you can configure the alarm linkage. You can disable the sound and light alarms entirely, or set them to activate only for specific events, such as human intrusion detected by SMD 3.0, rather than general motion, giving you precise control over deterrence.
Q4: Does this camera work with NVRs from other brands?
A4: This camera supports ONVIF (Profile S/Profile G) and CGI, which are industry standards for IP camera compatibility. This means it should be able to connect and record with most ONVIF-compliant Network Video Recorders (NVRs) from other brands, though full feature integration might vary compared to using a Dahua NVR.
Q5: How long can the camera record on a 256GB SD card?
A5: The recording duration on a 256GB Micro SD card depends on several factors, including the resolution, compression (H.265 vs. H.264), frame rate, and the amount of motion in the scene. As a general estimate for 4MP resolution with H.265 compression and motion-activated recording, a 256GB card could potentially store several weeks to over a month of footage, but this can vary significantly based on activity.
Q6: What makes this different from a "Pro" version of a Dahua camera?
A6: "Pro" versions typically offer more advanced features, higher-grade components, and often greater processing power. For example, a Pro version might include AI features like AcuPick for quick event search, higher levels of WDR (e.g., 140dB+), more extensive analytics (e.g., people counting, heat mapping), larger onboard storage options, or more robust build quality for extreme environments. This model is part of the WizSense 3 Series, offering strong intelligent features for its class, but not necessarily all the top-tier capabilities found in higher-end "Pro" or "AI Series" cameras.
Q7: Will the siren automatically activate if someone enters my property?
A7: Yes, the siren (and warm light) can be configured to automatically activate when a person or vehicle is detected entering a defined area (e.g., via Tripwire or Intrusion detection using Perimeter Protection, powered by SMD 3.0). You set up these "alarm linkages" in the camera's web interface or management software.
Q8: Does this camera require a monthly subscription for 4G connectivity?
A8: The camera itself does not require a subscription from Dahua. However, since it uses a 4G SIM card for internet connectivity, you will need to purchase a data plan from a mobile network provider, which typically involves monthly data charges similar to a smartphone plan.
