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 Explained
The Dahua DH-IPC-HFW3849T1-AS-PV-S3's Smart Dual Illuminators feature is a game-changer for nighttime surveillance. Typically, at night, the camera uses its invisible IR illuminator to capture clear black and white video. However, when the camera's intelligent algorithm detects a human or vehicle within the monitoring area, it automatically switches on the warm white light. This immediate change allows the camera to record full-color video of the event, capturing crucial details like clothing color or vehicle make that might be missed in black and white. Once the detected target leaves the area, the warm light switches off, and the IR illuminator turns back on, minimizing light pollution and maintaining a discreet presence when not actively deterring. This smart switching ensures that you get detailed, actionable evidence precisely when it's most needed, without continuous bright light disrupting the environment.
Advanced Motion Detection with SMD 3.0
SMD 3.0 (Smart Motion Detection) is far more sophisticated than traditional motion detection. Instead of simply reacting to any movement, this advanced intelligent algorithm can accurately categorize targets, distinguishing between actual threats like humans and vehicles, and less critical movements such as animals, swaying branches, or heavy rain. This significantly reduces false alarms, meaning you'll receive alerts only for events that truly matter. This precision saves you time and ensures you're not constantly checking your security feed for non-issues, making your security system more efficient and reliable.
Active Deterrence: More Than Just Recording
The Siren and Light Active Deterrence function transforms this camera from a passive recording device into an active security guardian. When the camera's intelligent monitoring (like intrusion or tripwire) detects an unauthorized human or vehicle, it doesn't just send an alert. It immediately triggers a loud siren and flashes bright red and blue lights. This immediate, attention-grabbing response is often enough to scare off potential intruders before they can cause any damage or gain entry. The ability to customize voice alerts further enhances this feature, allowing you to play specific warnings or messages relevant to your property, making the deterrence even more effective and personalized.
Seamless Integration and Control
This camera is designed for seamless integration into a comprehensive security system. It supports ONVIF (Profile S/G/T), ensuring compatibility with a wide range of network video recorders (NVRs) from various manufacturers, not just Dahua. For optimal performance and access to advanced AI features like intelligent search, pairing it with a Dahua Smart NVR is highly recommended. Furthermore, the One-tap Disarming function, accessible via the mobile app (DMSS), offers incredible convenience. You can easily enable or disable event linkages, like alarms and deterrence, with a single tap, adapting your security settings to different scenarios, such as when you're home versus away, or when expecting visitors. This flexible control puts the power of your security system directly in your hands.
Q&A
Can this camera record in color at night?
Yes, absolutely! While it typically uses invisible IR for black and white night vision, its Smart Dual Illuminators will automatically activate a warm white light when a person or vehicle is detected, allowing it to capture full-color video of the event for better detail.
How loud is the built-in speaker?
The speaker is designed to be loud enough for effective two-way communication and for the siren to act as a significant deterrent. While a specific decibel level isn't provided, it's powerful enough to be clearly heard in outdoor environments and to draw attention.
Can the deterrence lights and siren be disabled?
Yes, you have full control. You can enable or disable the siren and light alarm features through the camera's settings or via the mobile app. This allows you to tailor its behavior to your specific needs and avoid unwanted activations.
Does it work with NVRs from other brands?
Yes, this camera supports ONVIF (Profile S/G/T), which means it's generally compatible with network video recorders (NVRs) from other manufacturers that also support ONVIF. However, for the best experience and access to all advanced AI features, pairing it with a Dahua Smart NVR is recommended.
How long will a 256GB SD card record?
The recording duration depends on several factors: the resolution and frame rate you set, the amount of motion detected, and the compression (H.265 vs. H.264). With H.265 compression, a 256GB SD card can typically store several days to over a week of continuous recording, and significantly longer if only recording on motion detection events.
What makes this different from a "Pro" version?
The "WizSense 3 Series" indicates it's a highly capable camera with advanced AI features focused on human and vehicle detection, active deterrence, and smart illumination. While there might be "Pro" or "Ultra" series with even more specialized analytics (like facial recognition or more complex scene analysis), this model offers a robust and intelligent solution for most common surveillance needs, balancing features with cost-effectiveness.
Will the siren activate automatically?
Yes, the siren and red/blue lights are designed to activate automatically when specific intelligent monitoring events occur, such as a human or vehicle crossing a defined tripwire or entering an intrusion zone. You configure these rules, and the camera handles the automatic response.

Summary Recommendation
-
Choose the Newer Model (DH-IPC-HFW3849T1-AS-PV-S3) if:
- You require superior low-light color and black/white performance, as indicated by the lower minimum illumination values.
- You prioritize enhanced AI features with SMD 3.0 for potentially even fewer false alarms and improved detection.
- You want the benefit of dedicated AI Coding (AI H.265/H.264) for more efficient video compression, which can lead to bandwidth and storage savings.
- You need more flexible privacy masking with 8 configurable areas.
- You prefer the presence of dual microphones for potentially better audio capture and two-way talk.
- You desire both IR and warm light illuminators for versatile night vision capabilities (full-color with warm light, traditional B/W with IR).
-
The Older Model (DH-IPC-HFW3849T1-AS-PV) might still be suitable if:
- Cost is a significant factor, and you can find the older model at a reduced price.
- Your primary need is for 8MP resolution with active deterrence, and the slight improvements in low-light performance or AI are not critical for your specific application.
- You are comfortable with SMD Plus and don't strictly require SMD 3.0 or explicit AI Coding.
- The existing audio capabilities (single mic) and privacy masking (4 areas) are sufficient.
- Your environment primarily benefits from warm light illumination and doesn't explicitly require IR for a specific use case.
