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: Clarity When It Matters The Dahua DH-IPC-HDBW3849R1-ZAS-PV's Smart Dual Illumination technology provides an intelligent approach to night vision. By default, the camera uses its discreet infrared (IR) illuminators for black and white surveillance in low-light conditions. However, when the camera's intelligent algorithms detect a target (such as a human or vehicle) entering the monitoring area, it automatically switches on its warm white light illuminators. This allows the camera to capture crystal-clear, full-color video of the event, linking snapshots and video clips with vital visual details. Once the target leaves the area, the warm light switches off, returning to IR illumination. This intelligent switching not only ensures crucial full-color evidence is captured but also minimizes unnecessary light pollution in your environment, making it a thoughtful solution for residential and commercial settings alike.
SMD 3.0: Precision Detection, Fewer False Alarms Smart Motion Detection (SMD) 3.0 is a significant advancement in surveillance intelligence. Unlike traditional motion detection that can be triggered by anything from swaying branches to pets, SMD 3.0 leverages advanced deep learning algorithms to accurately distinguish between human and vehicle targets and other benign movements. This means you receive fewer irrelevant notifications and alarms, allowing you to focus on genuine security threats. For instance, you won't get an alert every time a cat walks across your driveway, but you will be promptly notified if a person or vehicle enters a restricted zone. This precision detection saves time, reduces alert fatigue, and enhances the overall effectiveness of your security system.
Active Deterrence: Beyond Just Recording This camera goes beyond simply recording events; it actively intervenes to prevent incidents. The integrated siren and red and blue strobe lights are powerful deterrents. When a perimeter event occurs (e.g., someone crosses a tripwire), the camera can automatically trigger these alarms. The siren can be customized with various pre-recorded messages or even your own uploaded audio, allowing for tailored responses. This immediate, localized deterrence can often prevent a situation from escalating, making the camera an active participant in your security strategy rather than just a passive observer. It's about taking proactive steps to protect your property and deter potential threats before they cause harm.
Seamless Integration and Management The DH-IPC-HDBW3849R1-ZAS-PV is designed for seamless integration into various security ecosystems. It supports standard protocols like ONVIF (Profile S/G/T), ensuring compatibility with a wide range of network video recorders (NVRs) and video management systems (VMS) from different manufacturers. For optimal performance and access to all intelligent features, pairing it with a Dahua Smart NVR and utilizing Dahua's management software like Smart PSS, DSS, or the DMSS mobile app (for iOS and Android) is recommended. This allows for unified control, easy configuration, intelligent search functions, and convenient remote access to live views and recorded footage from anywhere, enhancing your overall security management experience.

Q&A
Q: Can this camera record in color at night? A: Yes, it can. The camera features "Smart Dual Illuminators." In low light, it usually uses invisible infrared (IR) for black and white video. However, when it detects a human or vehicle, it automatically switches on its warm white light, allowing it to record the event in full color. Once the detected object leaves, it returns to IR mode.
Q: How loud is the speaker on this camera? A: While the exact decibel level isn't specified, the camera has a built-in 1-channel speaker designed for effective two-way talk and siren functions. It's loud enough to be clearly heard for communication and to provide a strong audible deterrent.
Q: Can the red and blue lights be disabled, or do they always activate? A: Yes, the sound and light alarms for active deterrence can be configured. You have control over when and how they activate. They can be set to trigger only for specific events (like intrusion or tripwire detection) or be disabled entirely if not desired.
Q: Does this camera work with NVRs from other brands? A: Yes, this camera supports ONVIF (Profile S/Profile G/Profile T), which is a common standard for IP cameras. This means it should be compatible with most third-party NVRs and video management systems that also support ONVIF. However, to access all of its advanced AI features and intelligent functions, using a Dahua Smart NVR is recommended.
Q: How long can the 256GB SD card record for? A: The recording duration on a 256GB SD card depends on several factors, including the resolution, frame rate, compression (H.265 is very efficient), and the amount of motion in the recorded area. For continuous recording at 8MP, it might last several days to a week. If set to record only upon motion detection or specific events, it could last significantly longer, potentially weeks or even months.
Q: What makes this camera different from a "PRO" version, if one exists? A: While this is a high-performance camera, "PRO" versions in Dahua's lineup often include additional advanced features such as higher-end AI capabilities (e.g., facial recognition, people counting), more robust environmental ratings, specialized optics for extreme conditions, or higher processing power for complex analytics. This model offers an excellent balance of smart features and cost-effectiveness for general deterrence and intelligent monitoring.
Q: Will the siren activate automatically if someone walks by? A: The siren will activate automatically based on the intelligent monitoring rules you configure. For example, if you set up a "tripwire" rule and a human or vehicle crosses that virtual line, the siren can be triggered. The camera's SMD 3.0 helps ensure that only human or vehicle detection triggers the alarm, reducing false activations from non-threatening movements.
