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 — Clear Color at the Right Time
This camera intelligently switches between infrared and warm white light based on motion detection. While IR maintains discreet, low-light monitoring by default, warm white light activates when a person or vehicle enters the frame. This ensures crucial footage is captured in vivid full colour when it matters most — ideal for identifying suspects, license plates, or clothing. After the subject leaves, the system returns to IR mode to reduce light pollution and energy use.
SMD 4.0 — Smarter Motion, Fewer False Alarms
Dahua’s Smart Motion Detection 4.0 uses deep-learning algorithms to distinguish humans and vehicles from irrelevant movement like animals, shadows, and blowing leaves. SMD 4.0 significantly reduces false alerts, making it more dependable for real-world environments. When paired with a Dahua AI NVR, the system also enables Quick Pick, letting you search recorded events by human or vehicle targets within seconds.
Active Deterrence — Prevent Crime, Not Just Record It
Equipped with dual flashing red and blue strobe lights plus a built-in speaker, this camera doesn’t just observe — it acts. You can set the camera to automatically trigger these deterrents when detecting motion, tripwire breaches, or intrusions. Customize audio messages via the DMSS app or Smart PSS software, letting you use warnings like “You are being recorded” or site-specific instructions. It's perfect for deterring loitering, theft, or trespassing.
AcuPick — Smart Search for Faster Review
Reviewing hours of footage is a thing of the past. AcuPick combines front-end AI detection with backend NVR search intelligence. By tagging humans or vehicles as they appear on video, the system lets you search for specific targets instantly. Need to find when a car entered your parking lot yesterday? AcuPick delivers it in seconds, eliminating blind fast-forwarding through endless timelines.
AI SSA (Scene Self-Adaption) — Set It and Forget It
Lighting conditions constantly change — shadows shift, day turns to night, or car headlights flare into view. With AI SSA, this camera adjusts brightness, contrast, white balance, and exposure automatically in real-time. The result? You always get balanced, clear images without needing manual tuning, even in mixed lighting environments like underground garages or streetfronts with variable light sources.
Cybersecurity & Data Protection — Built for Peace of Mind
Dahua includes professional-grade cybersecurity features like encrypted video streams, firmware authentication, user access controls, and HTTPS support. Your footage and configurations are protected from tampering or unauthorized access. Whether used in commercial, residential, or institutional settings, this camera is hardened against common cyber threats.
Built for the Elements — IP67 Certified
With an IP67-rated weatherproof body, this bullet camera resists dust, rain, and even water immersion up to 1 meter for 30 minutes. Whether installed in hot sun, freezing snow, or coastal rain, it’s engineered for harsh environments. The sturdy casing and wide voltage tolerance make it suitable for industrial sites, parking lots, or remote outdoor areas with unstable power.
App Integration & Remote Access
The camera is fully supported by the DMSS mobile app (iOS/Android), which allows users to view live feeds, playback recordings, receive push notifications, and control deterrence settings remotely. With support for smart event filtering, voice alert management, and one-tap disarming, it provides homeowners and installers alike with hands-on control from anywhere in the world.
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
Q: Can this camera record in colour at night?
Yes — the warm light activates on motion to deliver full-colour night footage, switching back to IR when idle.
Q: How loud is the built-in speaker?
Loud enough to be heard clearly in outdoor environments, suitable for verbal warnings and pre-recorded messages.
Q: Can I disable the lights or siren if I want a stealth setup?
Yes, both lights and audio deterrents can be turned off or scheduled through the DMSS app or NVR interface.
Q: Does it work with non-Dahua NVRs?
Yes, it supports ONVIF (Profiles S/G/T) and RTSP streams, so it's compatible with most third-party NVRs.
Q: How much video can the microSD card store?
With AI coding and a 512GB card, you can expect several weeks of footage, depending on bitrate and motion activity.
Q: What’s the difference between this and the PRO model?
The PRO version often includes higher bitrate support, more advanced analytics, or additional lenses — this model is optimized for smart detection and deterrence at a mid-tier price point.
Q: Will the camera trigger the siren automatically?
Yes, you can set it to activate lights and sound on specific events like human detection, tripwire, or intrusion alerts.
Q: Can I view and control it via mobile app?
Absolutely. It works with the Dahua DMSS app for live viewing, playback, push alerts, and configuration.
