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 for Clear Night Vision
This camera features Dahua's innovative Smart Dual Illuminators technology. At night, it typically uses invisible IR light for discreet monitoring. However, as soon as a human or vehicle is detected in the monitoring area, the warm white light automatically activates. This illuminates the scene, allowing the camera to capture full-color video and detailed information about the key event. Once the detected target leaves the area, the warm light switches off, and the IR illuminator turns back on, effectively reducing light pollution while ensuring critical moments are recorded in vibrant color. This provides a balance between continuous and discrete monitoring and detailed event capture.
Enhanced Detection with SMD 3.0
Dahua's Smart Motion Detection (SMD 3.0) goes beyond basic motion sensing. Powered by an intelligent deep learning algorithm, it precisely categorizes targets that trigger motion alarms, specifically focusing on humans and vehicles. This significantly reduces false alarms caused by rain, leaves, animals, or changes in lighting. With SMD 3.0, you receive more accurate and relevant alerts, allowing you to focus on actual threats and minimize unnecessary notifications, thereby saving time and improving response efficiency.
Active Deterrence with Sound and Light
The camera's active deterrence capabilities are a powerful tool for preventing incidents. When a perimeter event (like an intrusion or tripwire breach) occurs, the camera triggers a sound alarm via its built-in speaker and flashes vivid red and blue lights. You can choose from multiple pre-recorded voice prompts or even import your own customized voice messages to tailor the deterrence message. This immediate, visible, and audible response is designed to startle and deter intruders before they can cause damage, providing an effective first line of defense.
Seamless Integration and Management
This camera is part of the Dahua WizSense series, meaning it's designed to work seamlessly with Dahua's Smart NVRs and management software like Smart PSS and DSS, as well as the DMSS mobile app. This allows for centralized monitoring, advanced intelligent search functions, and easy control of camera settings and event linkages directly from your computer or smartphone. The "One-tap Disarming" feature, accessible via the mobile app, offers quick control over event linkages, making it convenient to arm or disarm the system as needed for various scenarios.
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 color at night?
A: Yes, the camera uses Smart Dual Illumination. It records in black and white with IR light normally, but when a human or vehicle is detected, the warm white light activates, and it records in full color.
Q: How loud is the speaker on this camera?
A: While the exact decibel level isn't specified, the built-in speaker is designed to provide an audible siren and two-way communication, making it effective for active deterrence and direct interaction.
Q: Can the red and blue flashing lights be disabled?
A: Yes, the active deterrence features, including the lights and siren, can typically be configured and disabled through the camera's web interface or the Dahua management software/app if you prefer not to use them.
Q: Does this camera work with NVRs from other brands?
A: Yes, the camera supports ONVIF (Profile S/G/T), which means it should be compatible with many third-party NVRs and video management systems that also support ONVIF. However, some advanced AI features might be best utilized with a Dahua WizSense NVR.
Q: How long can the SD card record footage?
A: The camera supports a Micro SD card up to 256GB. The actual recording duration depends on factors like resolution, compression (H.265 vs. H.264), frame rate, and the amount of motion detected. For continuous recording, 256GB can typically hold several days to over a week of footage.
Q: What makes this "WizSense" different from a standard camera?
A: WizSense cameras, like this one, integrate independent AI chips and deep learning algorithms. This allows for highly accurate human and vehicle detection (SMD 3.0) and intelligent functions like perimeter protection, significantly reducing false alarms and enabling faster, more targeted responses compared to cameras without AI.
Q: Will the siren activate automatically when motion is detected?
A: Yes, you can configure the camera to automatically activate the siren and flashing lights when specific intelligent events like intrusion or tripwire detection occur, particularly for human or vehicle targets.

Summary Recommendation
-
Choose the Newer Model (DH-IPC-HDBW3549R1-ZAS-PV) if:
- You require active deterrence capabilities with sound and light alarms.
- You need Smart Dual Illuminators to capture full-color video of key events at night while minimizing light pollution.
- Superior low-light color performance (0.003 lux vs. 0.005 lux) is critical.
- You benefit from dual built-in microphones and a speaker for enhanced two-way talk and audio detection.
- You prefer the latest iteration of SMD technology (SMD 3.0), although the older model boasts SMD 4.0/AI SSA, indicating the specific AI features might differ in focus or generation.
-
The Older Model (DH-IPC-HDBW3541RP-ZAS) might still be suitable if:
- Active deterrence and warm light illumination are not essential for your application.
- Your budget is a primary concern, as older models are typically more cost-effective.
- A slightly smaller and lighter form factor is preferred.
- You mainly rely on IR night vision and its 40m range is sufficient.
- The slightly longer DORI distances in the telephoto range are a priority, though the difference is marginal.
