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 features "Smart Dual Light," meaning it intelligently uses both infrared (IR) and warm visible light. In low-light conditions, it typically uses IR for standard black-and-white night vision. However, if a human or vehicle is detected, the camera can automatically switch on its warm LED lights to capture clear, full-color images, making identification easier. It can also be set to keep the warm lights on constantly for 24/7 color monitoring or only use IR.
SMD 4.0 (Smart Motion Detection) SMD 4.0 is Dahua's advanced motion detection technology. Unlike basic motion detection that triggers on any movement (like a bush swaying), SMD 4.0 uses deep-learning algorithms to differentiate between humans, vehicles, and other non-threatening objects (like animals, rain, or falling leaves). This drastically reduces false alarms, ensuring you only get notified about events that truly matter, saving you time and improving system efficiency.
AcuPick AcuPick is a powerful search tool, specifically for use with compatible Dahua AI NVRs (5-Series and above). After an event (like a person entering a protected area) is detected by the camera, AcuPick allows you to quickly search for all instances of that specific human or vehicle across your recorded footage. Instead of sifting through hours of video, you can pinpoint relevant clips with just a few clicks, making evidence retrieval much faster and more efficient.
AI Scene Self-Adaptation (SSA) AI SSA enables the camera to intelligently analyze the scene and automatically adjust its image parameters, such as exposure, white balance, and noise reduction. This ensures optimal image quality across various lighting conditions, from bright daylight to challenging low-light environments, without requiring manual adjustments. The result is consistently clear and detailed video.
Active Deterrence (Red & Blue Lights + Audio) This camera is designed to be proactive. When its intelligent detection identifies an intruder (human or vehicle) in a defined area, it can immediately activate a loud siren (up to 110dB) and bright red and blue flashing lights. This highly visible and audible alarm acts as a strong deterrent, often scaring away intruders before they can cause damage or gain entry. The two-way talk feature further enhances this, allowing you to verbally warn or engage with individuals on your property.
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.
More About AcuPick - Smart Video Search with Precision AI
Dahua’s AcuPick technology revolutionises video surveillance by using advanced AI to pinpoint people or vehicles across recorded footage with remarkable speed and accuracy. Instead of scrubbing through hours of video manually, AcuPick enables users to filter footage by specific targets, drastically cutting down search times and boosting operational efficiency. Integrated into a range of Dahua cameras (including TiOC series) and compatible NVRs, AcuPick delivers a seamless and intelligent search experience.
Highlights of AcuPick:
AI-Driven Precision:
AcuPick leverages intelligent algorithms to differentiate between human and vehicle activity, refining search results to what truly matters.
Smart Filtering:
Search footage using key attributes like clothing colour or vehicle type—no need to know the exact time an incident occurred.
Instant Video Recall:
With just a few clicks, users can zero in on critical moments, improving response times and streamlining investigations.
False Alarm Reduction:
By filtering out irrelevant motion, AcuPick helps reduce nuisance alerts, leading to more reliable monitoring.
Flexible Deployment:
Whether through Dahua's smart cameras or NVR integration, AcuPick fits into a wide range of security setups.
Practical Applications:
-
Retail & Offices: Track customer flow or monitor for unauthorized access.
-
Car Parks & Garages: Instantly retrieve footage of accidents or suspicious activity.
-
Public Spaces: Quickly find persons of interest using visual identifiers.
-
Residential Estates: Enhance safety by identifying vehicle movements or visitors.
AcuPick transforms surveillance from reactive monitoring to proactive intelligence, saving time while elevating security across the board.
Q&A
Q: Can this camera record in color at night?
A: Yes, this camera features "Smart Dual Light" technology and WizColor, allowing it to capture full-color video even in low-light conditions. It can use warm LED light to illuminate the scene for color recording when triggered by detection or if set to always-on.
Q: How loud is the siren on this camera?
A: The built-in siren can reach up to 110dB, which is loud enough to be a significant deterrent and noticeable in most residential or small business environments.
Q: Can the red and blue flashing lights and siren be disabled or controlled remotely?
A: Yes, you can enable, disable, or control the active deterrence features (lights and siren) remotely through the Dahua mobile app (DMSS) or compatible management software. It also supports "one-tap arming and disarming."
Q: Does this camera work with NVRs from other brands?
A: The camera is ONVIF (Profile S, G, T, M) compliant, meaning it should have basic compatibility (video stream) with most ONVIF-supported NVRs from other brands. However, for full functionality, especially advanced AI features like AcuPick and intelligent search, it is highly recommended to pair it with a compatible Dahua WizSense AI NVR.
Q: How long can the camera record on a 512GB SD card?
A: The recording duration depends on several factors, including the video resolution, frame rate, compression (H.265 vs. H.264), motion activity, and whether continuous or event-based recording is used. With H.265 AI coding and event-based recording (triggered by SMD 4.0), a 512GB card can provide several weeks to months of footage for typical home or small business use.
Q: What makes this the "PRO" version compared to other Dahua TiOC cameras?
A: The "PRO" in this model often indicates enhanced features, such as a larger 1/1.8" image sensor for even better low-light performance, more advanced AI capabilities like full-image face detection, potentially higher processing power (indicated by RAM), and improved AI algorithms like the "Xinghan Large-Scale AI Models-Vision" for more accurate and comprehensive intelligence.
Q: Will the siren and lights activate automatically when someone enters my property?
A: Yes, if you configure the "Perimeter Protection" rules (like tripwire or intrusion zones) in the camera's settings, the siren and red/blue lights can be set to automatically activate when a human or vehicle crosses those defined boundaries.
