Dahua SD6C3425GB-HNR-A-PV1 4MP TIOC 2.0 IP 25X PTZ Camera IR 150m

Combining 25x optical zoom with integrated active deterrence and AI-driven analytics, the SD6C3425XB-HNR-A-PV1 is engineered for large-scale outdoor surveillance where a single camera must do the work of many. This 4MP TIOC 2.0 PTZ camera features a motorised 5.4-135mm lens with 360° endless pan, giving security operators the flexibility to scan an entire site, lock onto a target, and track it automatically without touching a control interface. The Smart Dual Light system selects between full-colour white light illumination within 50 metres and infrared coverage extending to 150 metres based on scene conditions. When WizSense AI detects a human or vehicle breaching a defined perimeter zone, integrated red and blue strobe lights and a built-in speaker can respond automatically with a visible and audible warning. Face detection, human and vehicle classification, and metadata generation further support post-event review and alert management. IP66 weatherproofing and an operating temperature range of -40°C to +70°C make it deployable across demanding outdoor environments year-round.

Key Capabilities

Best For

• Wide-Area Sites Requiring Single-Camera Coverage: 360° endless pan and 25x optical zoom allow one camera to monitor scenes that would otherwise require several fixed installations, reducing cabling, mounting, and ongoing maintenance costs across large commercial and industrial sites.
• High-Risk Perimeters Where Deterrence Matters: TIOC 2.0 strobe lights and AI-triggered voice alarms make this camera appropriate for sites where a visible, automated warning response is part of the security strategy, including fenced industrial yards, utility sites, and restricted-access facilities.
• Unmanned or Remote-Monitored Locations: Auto-tracking operates without permanent operator input, following detected targets independently. This makes the camera suited to facilities monitored remotely or during after-hours periods when a staffed control room position is not viable.
• Extreme-Climate Outdoor Environments: The -40°C to +70°C operating range and IP66 housing support deployment in exposed coastal positions, cold-climate regions, high-heat industrial rooftops, and dusty open yards without requiring additional environmental enclosures.
• Applications Needing Long-Range Subject Identification: A DORI identify range of 165 metres and a detect range exceeding 1,600 metres suit this camera to open perimeters, large car parks, and extended approach roads where early detection and subject identification provide a meaningful operational advantage.

Why Choose the SD6C3425XB-HNR-A-PV1

Fixed cameras lock coverage to a single pre-aimed angle. The SD6C3425XB-HNR-A-PV1 removes that limitation entirely by combining 360° endless pan, 90° tilt, and 25x optical zoom with auto-tracking in a single outdoor housing. Where an entry-level PTZ offers basic motion detection, this model applies WizSense AI to classify each alert by target type, meaning human and vehicle detections are separated from environmental noise before any alarm fires. The TIOC 2.0 integration goes beyond passive recording: the strobe warning lights and customisable voice alerts are wired directly into the AI event pipeline, so the camera acts on confirmed detections automatically. Starlight performance at 0.005 Lux in colour mode means usable colour footage is available within 50 metres of the mounting point without relying on external lighting, and infrared extends that coverage to 150 metres for longer approaches. Available through Krazy Tech Deals as part of a professional PTZ range, this model is suited to commercial, industrial, and infrastructure sites where a fixed camera cannot match the coverage or response capability required.

Buyer Decision Tips

Key Features & Technical Specifications

Ideal Use Cases

Choosing the Right Model

• Choose this model if: Your site requires wide-area PTZ coverage with 25x optical zoom, TIOC 2.0 active deterrence including strobe lights and voice alarms, WizSense AI perimeter protection and auto-tracking, full-colour night vision within 50 metres, and IP66 all-weather performance in a single camera across commercial, industrial, or public-space installations.
• Choose a different model if: Your application involves monitoring a fixed, single-angle zone where PTZ rotation provides no operational benefit, your network infrastructure is limited to standard PoE (802.3af) switches with no upgrade path to PoE+, or your site scale and budget are better matched to a fixed turret or bullet camera with a defined field of view rather than a full PTZ deployment.

FAQs

1. What does TIOC 2.0 add to this PTZ camera beyond standard PTZ features?
   TIOC 2.0 integrates three capabilities: full-colour illumination at night, hardware-based active deterrence (red and blue strobe lights plus a built-in speaker with customisable voice alerts), and AI-driven event detection from WizSense. A standard PTZ camera captures and repositions on demand. This model can also detect, classify, and respond to confirmed intrusion events automatically without requiring an operator to be watching the feed at the moment it occurs.
2. How does the Smart Dual Light system decide which illuminator to use?
   The Smart Dual Light system monitors scene brightness and detected activity, then selects between white light and infrared automatically. White light is recommended within 50 metres for vivid colour footage at night. Beyond that distance, or when conditions do not warrant white light activation, the system switches to infrared illumination, which extends coverage to 150 metres in black-and-white mode without producing visible light that could be disruptive to the wider environment.
3. Can this camera be powered by a standard PoE switch?
   No. The SD6C3425XB-HNR-A-PV1 requires PoE+ (802.3at) when powered over Ethernet, with maximum power consumption reaching 23W when IR, white light, strobe warning lights, speaker, and PTZ drive are all active simultaneously. Standard PoE (802.3af) is limited to 15.4W and cannot sustain the camera under full-load conditions. Use a PoE+ rated switch or midspan injector, or supply 24VDC locally at the installation point.
4. Does the active deterrence system activate automatically or does an operator need to trigger it manually?
   Both modes are supported. The strobe warning lights and voice alarms can be configured to activate automatically when WizSense detects a confirmed human or vehicle intrusion within a defined perimeter zone. They can also be triggered manually by a monitoring operator. Pre-recorded voice messages are customisable, allowing site-specific audio warnings to play in response to particular event categories.
5. What is the DORI performance of the 25x optical zoom lens?
   At maximum telephoto (135mm), the lens achieves a DORI detect range of 1,655 metres, an observe range of 653 metres, a recognise range of 331 metres, and an identify range of 165 metres. In practical terms, this means a single camera can confirm the presence of a person at over 1.6 kilometres while retaining the ability to identify individual subjects at 165 metres, covering ground that would require a significant number of fixed cameras to replicate.
6. How many preset positions does the camera support and how fast does it move between them?
   The camera supports 300 programmable preset positions, allowing operators to map a comprehensive set of key monitoring points across the entire scene. Repositioning between presets occurs at a pan speed of 240°/s and tilt speed of 150°/s. This enables rapid automated patrol sequences covering a large site and near-instant recall of specific positions during live monitoring when an incident develops in a known zone.
7. What AI analytics are included and are they processed on the camera itself?
   WizSense analytics built into the camera cover perimeter protection, face detection, human and vehicle target classification, auto-tracking, and metadata generation. All processing occurs on the device itself without requiring an external server or separate analytics licence for core functions. For integration with specific third-party VMS platforms or advanced analytics workflows, contact Krazy Tech Deals to confirm compatibility requirements for your system configuration.
8. Does this camera support two-way audio communication and what audio formats are available?
   Yes. A built-in microphone and built-in speaker are both confirmed on this model, enabling two-way audio so monitoring operators can communicate directly to people on site through the camera. Supported audio compression formats include G.711a, G.711Mu, G.726, MPEG2-Layer2, G722.1, and PCM. For video, H.265+ is recommended to manage storage and bandwidth efficiently when recording continuous 4MP PTZ footage with frequent zoom and pan activity over extended recording periods.
