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
The IPC-HDW3849H-AS-PV-PRO features Smart Dual Light technology, combining both infrared (IR) and warm light illuminators. During normal nighttime operation, the camera uses its IR lights for discreet black-and-white monitoring. However, when an intelligent event is detected (like a person or vehicle intrusion), the camera can automatically switch to its warm white light, capturing full-color images and acting as a visible deterrent. This provides the best of both worlds: stealthy monitoring when things are calm, and bright, clear, color evidence when action is needed.
SMD 4.0 (Smart Motion Detection)
SMD 4.0 is an advanced evolution of motion detection that significantly improves accuracy. Instead of simply reacting to any movement, it uses deep learning algorithms to distinguish between humans, vehicles, and irrelevant objects (like animals, falling leaves, or changes in lighting). This dramatically reduces false alarms, meaning you'll only be notified about events that truly matter, saving you time and ensuring critical alerts aren't missed amidst noise.
AcuPick
AcuPick is a powerful search tool that works in conjunction with compatible back-end devices (like AI NVRs). If an event is triggered (e.g., a person or vehicle is detected by SMD), AcuPick allows you to quickly and accurately search through live or recorded video to locate specific targets. You can efficiently filter by human or vehicle, making it incredibly fast to find relevant footage without sifting through hours of non-event recordings.
AI SSA (AI Scene Self-Adaptation)
The camera's AI SSA (AI Scene Self-Adaptation) feature uses deep learning algorithms to automatically adjust image parameters based on the current scene conditions. This means the camera intelligently optimizes settings like brightness, contrast, and exposure to ensure the best possible image quality in varying environments, from bright daylight to challenging low-light scenarios, all without manual intervention.
Active Deterrence (Lights + Audio)
Beyond simply recording, this camera actively deters potential threats with its Sound and Light Alarm system. Upon detecting an intrusion or tripwire breach, the camera can activate bright red and blue strobe lights and emit a powerful siren. The siren includes multiple built-in sounds, and you can even upload your own customized voice messages, allowing you to tailor the warning or instruction delivered to intruders, making it a highly effective first line of defense.
Seamless Integration
The IPC-HDW3849H-AS-PV-PRO is designed for versatile integration. It supports ONVIF (Profile S, G, T) for compatibility with a wide range of third-party NVRs and VMS platforms. Additionally, it works seamlessly with Dahua's own management software like Smart PSS Lite, DSS, and the mobile client apps (DMSS, DoLynk Care) for iOS and Android, providing convenient remote viewing, management, and push notifications directly to your smartphone.
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.
