Product SKU: DH-SD6C3425XB-HNR-A-PV1
Product Overview
Wide-area monitoring across a large commercial site, industrial yard, or public precinct demands more than a fixed camera can deliver — and the SD6C3425XB-HNR-A-PV1 is engineered precisely for that challenge. This 4MP TIOC 2.0 PTZ camera pairs a 25x optical motorised zoom lens (5.4–135mm) with 360° endless pan rotation, giving operators the ability to inspect any point within a vast scene from a single mounting position. Featuring Dahua’s Smart Dual Light system, it automatically switches between full-colour white light illumination and infrared coverage up to 150 metres depending on scene conditions. Integrated red and blue strobe warning lights and a built-in speaker activate in response to AI-detected intrusions, turning the camera into an active deterrent rather than a passive recorder. WizSense AI analytics deliver perimeter protection, face detection, and auto-tracking, while the 1/2.8″ STARVIS CMOS sensor maintains usable imagery down to 0.005 Lux in colour mode. IP66 weatherproofing and an operating range of –40°C to +70°C extend its suitability to demanding outdoor environments year-round.
Key Capabilities
25x Optical Zoom with Long-Range DORI
The motorised 5.4–135mm lens delivers a DORI detect range of 1,655 metres and an identify range of 165 metres, allowing one camera to cover ground that would otherwise require multiple fixed units. Field of view adjusts from 55.8° wide to 2.9° tele, enabling both broad scene overview and close detail capture.
Smart Dual Light — IR + Full Colour
The camera intelligently toggles between infrared illumination (up to 150m) and visible white light based on scene brightness and detected activity. White light is recommended within 50 metres for vivid colour footage at night, while the IR illuminator handles longer-range coverage without generating unwanted light pollution.
TIOC 2.0 Active Deterrence
Red and blue strobe warning lights combined with a built-in speaker and customisable voice alerts can trigger automatically upon AI-detected intrusion events or manually by an operator. This allows the camera to intervene in real time, discouraging unauthorised access before an incident develops further.
WizSense AI — Perimeter Protection & Face Detection
Deep learning-based analytics classify targets as human or vehicle, sharply reducing event noise from animals or environmental movement. Perimeter protection rules and face detection generate actionable alerts and rich metadata, supporting faster incident response and more efficient video retrieval during post-event review.
Auto Tracking Across Large Scenes
Once a target is detected, the camera uses pan, tilt, and zoom to follow the subject automatically across the monitored area without operator input. With pan speeds up to 240°/s at preset and 300 programmable preset positions, the camera repositions rapidly between key zones as operational priorities shift.
Starlight Low-Light & 120dB WDR
The 1/2.8″ STARVIS CMOS sensor achieves a minimum illumination of 0.005 Lux in colour mode and 0.0005 Lux in black-and-white mode, maintaining detail in near-total darkness. Combined with 120dB wide dynamic range, the camera handles mixed lighting environments including backlit entrances and floodlit yards without image washout.
Best For
- Large Commercial Sites Requiring Single-Camera Coverage: The 25x optical zoom and 360° endless pan allow one camera to survey the scale of area that typically requires several fixed installations, reducing infrastructure cost and complexity.
- Sites Where Active Deterrence Is a Priority: TIOC 2.0 strobe lights and voice alarms triggered by WizSense AI make this camera appropriate for high-risk perimeters where a visible, automated warning response is part of the security plan.
- Facilities Needing After-Hours Unmanned Monitoring: Auto-tracking removes the need for a permanently staffed operator position — the camera responds to targets independently, making it suited to sites monitored remotely or outside business hours.
- Outdoor Environments with Extreme Temperature Exposure: The –40°C to +70°C operating range and IP66 housing support deployment in cold-climate regions, exposed coastal locations, and high-heat industrial settings without requiring additional environmental enclosures.
- Applications Requiring Long-Range Identification: With a DORI identify range of 165 metres and a detect range exceeding 1,600 metres, this camera is suited to perimeters, open yards, and approaches where early detection and subject identification are operationally important.
Why Choose the SD6C3425XB-HNR-A-PV1
A standard fixed IP camera covers a single, predetermined angle — this PTZ replaces multiple fixed units by combining 360° endless pan, 25x optical zoom, and auto-tracking in a single housing. Unlike entry-level PTZ cameras that rely on basic motion detection, the SD6C3425XB-HNR-A-PV1 integrates WizSense AI specifically classifying humans and vehicles, which means alert fatigue from wildlife, debris, or weather is significantly reduced. The TIOC 2.0 feature set goes further still: strobe lights and voice alarms are not just add-ons here — they integrate directly with the AI event pipeline so warnings fire automatically when perimeter rules are breached. Starlight performance down to 0.005 Lux combined with the Smart Dual Light system means colour-at-night footage is available within 50 metres, and infrared extends coverage beyond that without extra infrastructure. Available through Security Wholesalers as part of a professional PTZ range, this model is suited to commercial, industrial, and infrastructure sites where a basic camera simply cannot match the coverage or response requirements.
Buyer Decision Tips
Buyer Tip — Power Supply Planning: This camera requires PoE+ (802.3at) when powered over Ethernet, with maximum consumption reaching 23W under full load — illuminators, warning lights, speaker, and PTZ drive all active simultaneously. Standard PoE (802.3af) switches are capped at 15.4W and will not reliably power this unit under those conditions. Confirm your switch or midspan injector is PoE+ rated before installation, or plan for a 24VDC local power supply run to the mounting position.
Buyer Tip — White Light Positioning: The full-colour white light illuminator is rated for effective use within 50 metres. If your primary target zone for colour-at-night imagery — such as an entry point, cashier area, or loading dock gate — sits beyond that distance from the mounting position, the camera will fall back to IR-based black-and-white imaging in that zone. Factor mounting height, standoff distance, and zoom angle into your positioning plan before installation to maximise colour night performance where it matters most for your site.

Ideal Use Cases
Retail Centres and Shopping Precincts
Pan across large floor areas, monitor multiple entrances, and escalate to active deterrence via strobe and voice alarm when WizSense detects human intrusion after hours — all without requiring additional camera positions or static coverage zones.
Warehouses and Distribution Centres
Auto-tracking follows personnel and vehicles across loading docks and racking aisles automatically. The 25x zoom allows operators to zoom from a wide yard overview into specific bays or access points without repositioning hardware or adding fixed camera coverage.
Industrial and Critical Infrastructure Sites
An operating temperature range of –40°C to +70°C and IP66 weatherproofing allow deployment across mining sites, utilities infrastructure, and manufacturing facilities without additional environmental housing, even under conditions of sustained heat, cold, or dust exposure.
Perimeter and Boundary Protection
IR illumination to 150 metres combined with WizSense perimeter protection rules allows the camera to detect boundary intrusions along fences and walls in near-total darkness, triggering automatic strobe and audio warnings before personnel can reach sensitive areas.
Car Parks and Open Yard Areas
360° endless pan and auto-tracking provide continuous oversight of vehicle movements across large open surfaces. Face detection at entry and exit points adds an identification layer for access management and post-event review without requiring separate dedicated cameras at each lane.
Public Spaces and Town Centres
Two-way audio via the built-in microphone and speaker allows operators to communicate directly through the camera during incidents. Combined with WizSense crowd monitoring and active deterrence, this makes the camera suitable for community safety applications requiring real-time operator presence.
Choosing the Right Model
- Choose this model if: Your site requires wide-area PTZ coverage with 25x optical zoom, integrated active deterrence (strobe lights and voice alarms), WizSense AI perimeter protection and auto-tracking, full-colour night vision, and all-weather performance in a single camera — particularly across large commercial, industrial, or public-space installations.
- Choose a different model if: Your application involves monitoring a fixed, single-angle zone where PTZ rotation adds no operational benefit, your existing network infrastructure is limited to standard PoE (802.3af) switches without PoE+ upgrade capacity, or your budget and site scale are better matched to a fixed turret or bullet camera with a defined field of view.
FAQs
- What does TIOC 2.0 mean on this camera and how does it differ from a standard PTZ?
TIOC 2.0 (Triple Intelligence Optimised Camera, version 2) refers to the combination of full-colour night illumination, active deterrence hardware (strobe lights and speaker), and AI-driven event detection working together in a single unit. A standard PTZ camera captures and zooms — this model additionally warns, deters, and classifies threats automatically without operator intervention at the time of the event. - What is the effective range of the white light illuminator versus the IR illuminator?
The full-colour white light illuminator is recommended for use within 50 metres for optimal colour image quality at night. Beyond that range, or when no activity is detected, the Smart Dual Light system automatically switches to the infrared illuminator, which extends coverage up to 150 metres in black-and-white mode. Mounting position and zoom angle both affect which illuminator will be most effective for your target zone. - Will a standard PoE switch power this camera?
No. The SD6C3425XB-HNR-A-PV1 requires PoE+ (802.3at) when powered over Ethernet, with a maximum draw of 23W under full load. Standard PoE (802.3af) is limited to 15.4W and cannot reliably sustain the camera when illuminators, warning lights, speaker, and PTZ drive are simultaneously active. Use a PoE+ rated switch or midspan injector, or supply 24VDC locally at the installation point. - Can the active deterrence features be triggered automatically, or does an operator need to initiate them?
Both modes are supported. The red and blue strobe lights and voice alarms can be configured to trigger automatically when the WizSense AI detects a perimeter breach or human/vehicle intrusion event. They can also be activated manually by a monitoring operator. Customisable voice alerts allow site-specific pre-recorded messages to be played back in response to specific event types. - How many preset positions does this camera support, and how quickly can it move between them?
The camera supports up to 300 programmable preset positions, allowing operators to map key points of interest across the entire monitored scene. Repositioning between presets occurs at a pan speed of up to 240°/s and tilt speed of up to 150°/s, enabling rapid automated patrols or near-instant manual repositioning to priority zones without delay. - What AI analytics are built into this camera and do they require a separate software licence?
The camera includes WizSense AI covering perimeter protection, face detection, human and vehicle classification, auto-tracking, and metadata generation — all processed on the camera itself. These analytics are embedded in the device firmware. For integration with third-party VMS platforms or advanced analytics pipelines, contact Security Wholesalers to confirm compatibility requirements for your specific system configuration. - Is this camera suitable for use in extreme outdoor temperatures?
Yes. The SD6C3425XB-HNR-A-PV1 is rated for operating temperatures from –40°C to +70°C, covering both cold-climate and high-heat environments. The IP66 housing provides protection against rain ingress and dust without requiring an additional external enclosure, making it deployable across exposed outdoor positions including rooftop mounts, perimeter poles, and open industrial structures. - Does this camera support two-way audio and what compression formats are available?
Yes. A built-in microphone and speaker enable two-way audio, allowing monitoring operators to communicate directly through the camera to people on site. Supported audio formats include G.711a, G.711Mu, G.726, MPEG2-Layer2, G722.1, and PCM. For video, H.265+ is recommended as it significantly reduces storage and bandwidth requirements compared to H.264 when recording continuous 4MP PTZ footage over extended periods.
