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
This camera intelligently switches between infrared (IR) and warm white LED lighting to balance visibility and energy efficiency. In low-light conditions, the IR light is used by default to minimize light pollution. When human or vehicle motion is detected, the camera automatically switches to white light mode, capturing full-color video for better evidence. Once the subject leaves the scene, the camera reverts to IR mode. This helps reduce false alarms while preserving detailed visuals of important events.
SMD 4.0 (Smart Motion Detection)
SMD 4.0 uses advanced AI algorithms to filter out non-human and non-vehicle motion, such as animals, shadows, or leaves. This dramatically reduces false alarms, allowing users to focus only on relevant security threats. When paired with an AI NVR, users can also take advantage of Quick Pick technology — which lets you rapidly locate human or vehicle events from stored footage without scrubbing through hours of video.
AcuPick
AcuPick is a powerful AI search tool that allows you to locate a specific person or vehicle across recorded footage — in seconds. It works by comparing characteristics (clothing, shape, movement pattern, etc.) of a target and scanning through video archives for matching appearances. This is ideal for forensic search applications, such as identifying a suspect who passed through multiple camera views.
AI Scene Self-Adaption (SSA)
This camera features AI-based SSA, which automatically adjusts key image settings such as exposure, contrast, and white balance based on scene conditions. Whether the environment is dimly lit, backlit, or prone to glare, SSA dynamically enhances clarity to ensure optimal visual results at all times — with no manual tuning required.
Active Deterrence (Red/Blue Strobe + Siren)
Equipped with visible red and blue flashing lights and a customizable voice siren, the camera can respond immediately when an intrusion or perimeter breach is detected. These deterrents can be configured to trigger during specific hours, motion types, or zones. The built-in speaker supports pre-loaded messages or custom audio clips, making it effective for site-specific alerts like “Restricted Area — Leave Immediately.”
AI-Powered IVS (Intelligent Video Surveillance)
With built-in IVS capabilities, including Tripwire and Intrusion Detection, the camera can distinguish between human and vehicle motion for smarter event filtering. You can define virtual zones and lines on the monitoring area, and the camera will only trigger alerts when a person or car crosses them — perfect for driveways, building entrances, or restricted zones.
One-Tap Disarming via App
The Dahua DMSS mobile app allows users to instantly disarm event-based notifications with a single tap. This is useful for homeowners or small business owners who want to temporarily disable alerts during known activity (e.g., lawn mowing, cleaning, deliveries) and reactivate protection afterward — all without logging into complex settings.
Seamless Integration with AI NVRs and Software
This model integrates smoothly with Dahua’s Smart NVRs and management platforms like Smart PSS Lite, DMSS, and DSS. When used with compatible AI NVRs, you gain access to enhanced features like advanced video analytics, intelligent search filters, storage management, and event correlation — helping you build a comprehensive, scalable security system.
Weatherproof, Wide Voltage Protection
Built with a robust metal casing and rated IP67, this camera is fully weatherproof — capable of operating in extreme heat, cold, rain, or dust. It also supports wide voltage input tolerances, ensuring stable performance even in areas with fluctuating power levels, which is crucial for outdoor and industrial applications.
Voice Alert Upload
Users can upload custom voice files (e.g. “Private Property — No Trespassing”) to replace the default alarm sounds. This feature offers a personalized security touch for specific applications like schools, warehouses, gated communities, or retail stores, enhancing both effectiveness and professionalism.
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.
