Product Overview
Wide-area monitoring across large open sites demands more than a fixed camera can deliver, and the Dahua SD6CE445GB-HNR is built to meet that requirement head-on. This network PTZ camera combines a 45x optical zoom with Starlight low-light performance, producing usable 4MP footage at colour sensitivities down to 0.005 Lux. IR illumination extends to 250 m across 6 built-in LEDs with Smart IR control that adjusts intensity as the lens zooms, preventing overexposure at close range. The SD6CE445GB-HNR includes Auto-Tracking 3.0, which locks onto detected subjects and follows them autonomously across the full 360-degree endless pan range. Perimeter protection rules cover tripwire, intrusion, fence climbing, loitering, parking detection, and people gathering, all tied to linkage tracking so the camera repositions the moment an alert fires. SMD 4.0 and Quick Pick further refine detection by classifying humans and vehicles before triggering alarms. With IP67 and IK10 ratings alongside TVS 8000V lightning protection, the SD6CE445GB-HNR suits demanding outdoor environments including exposed rooftop mounts and wide industrial perimeters.
Key Capabilities
45x Optical Zoom with DORI Coverage
The 3.95 mm to 177.75 mm lens delivers a detection range of 2,451 m and an identification range of 245 m, giving operators the ability to confirm subject detail at distances that would defeat fixed cameras entirely. Field of view shifts from 65.7 degrees wide to 1.9 degrees narrow as the lens zooms.
Starlight Low-Light Imaging
The 1/2.8-inch STARVIS CMOS sensor with an F1.6 maximum aperture captures colour video down to 0.005 Lux and monochrome video down to 0.0005 Lux. When light disappears entirely, 6 IR LEDs reach 250 m with automatic Smart IR intensity adjustment tied to the zoom position.
Auto-Tracking 3.0 with Linkage Tracking
When a perimeter rule triggers, Auto-Tracking 3.0 repositions the camera autonomously and follows the subject across the scene. Linkage tracking ties IVS alerts directly to pan-tilt movement, so the camera does not wait for operator input before it starts following a detected vehicle or person.
Comprehensive Perimeter Protection (IVS)
Onboard IVS rules include tripwire, intrusion, fence climbing, loitering detection, abandoned and missing object detection, fast moving, parking detection, and people gathering. Vehicle and human alarm classification reduces nuisance triggers from animals, debris, and lighting changes.
Extreme Environmental Protection
IP67 dust and water ingress protection, IK10 impact resistance, and TVS 8000V lightning and surge protection allow installation in exposed outdoor positions including elevated masts, rooftop towers, and industrial perimeter poles where weather and electrical transients are a constant concern.
300 Presets, Tours, Patterns, and Scans
Operators can store up to 300 preset positions and configure 8 patrol tours with up to 32 presets each, alongside 5 patterns and 5 scan sequences. Power-off memory retains the last position after a restart, and idle motion keeps the camera active when no operator commands are being sent.
Best For
- Large outdoor perimeters: The 45x optical zoom and 360-degree endless pan cover fence lines, boundary walls, and open yards from a single elevated mount, reducing the number of camera positions required across a wide site.
- Sites requiring autonomous incident response: Auto-Tracking 3.0 combined with linkage tracking means the camera follows a detected subject without operator intervention, which suits locations where live monitoring staffing is limited or intermittent.
- Exposed coastal or industrial environments: TVS 8000V lightning protection and an operating temperature range of -40 degrees C to +70 degrees C make this camera appropriate for harsh outdoor installations where standard PTZ units would require additional protection measures.
- Sites needing multi-rule perimeter analytics: The range of IVS rules, from fence climbing to abandoned object detection, supports complex detection scenarios across ports, logistics yards, utilities, and critical infrastructure sites where a single tripwire rule is insufficient.
Why Choose the SD6CE445GB-HNR
Where a fixed camera covers one angle, the SD6CE445GB-HNR covers an entire perimeter from a single mounting point. The 45x optical zoom is the defining specification here: it gives operators a DORI detection range of 2,451 m while still allowing close identification at 245 m, without switching cameras or accepting a compromise in detail. The Starlight sensor retains colour imaging at 0.005 Lux, which means usable footage in near-darkness before the IR illuminators even engage. Unlike PTZ cameras that rely solely on operator-directed movement, the Auto-Tracking 3.0 engine and linked IVS rules on the SD6CE445GB-HNR turn the camera into an active monitoring tool rather than a passive one. The combination of SMD 4.0, Quick Pick, and vehicle/human classification reduces the volume of nuisance alerts that operators have to review. Available through Security Wholesalers, the SD6CE445GB-HNR is a capable choice for commercial and industrial sites where coverage range, night performance, and analytics depth all need to work together from one mounting position.
Buyer Decision Tips
Buyer Tip 1 – PoE+ vs 24VDC Power: The SD6CE445GB-HNR draws up to 25W at maximum load, which requires a PoE+ (802.3at) switch port rather than a standard PoE (802.3af) port. Confirm your switch supports 802.3at before ordering. If running 24VDC instead, ensure cable gauge and run length are appropriate for the 2.5A draw over the distance to the camera.
Buyer Tip 2 – Auto-Tracking and Preset Planning: Auto-Tracking 3.0 performs best when the camera has a clear unobstructed sightline across the monitored area. Before configuring patrol tours and IVS rules, map the site to identify blind spots created by structures, vegetation, or terrain. Use the 300 available presets to anchor key positions around the site perimeter so that idle motion keeps coverage active when Auto-Tracking is not engaged.

Ideal Use Cases
Ports and Logistics Yards
The 45x zoom and 360-degree pan allow a single camera to monitor container stacking zones, access roads, and wharf edges. Parking detection and people gathering IVS rules alert operators to unauthorised vehicle positioning or crowd formation without requiring constant operator attention.
Critical Infrastructure Perimeters
Fence climbing and intrusion detection rules, combined with Auto-Tracking 3.0 and TVS 8000V lightning protection, make the SD6CE445GB-HNR suited to substations, water treatment facilities, and telecommunications sites where perimeter breach detection and camera survivability are both essential requirements.
Mining and Construction Sites
The operating temperature range of -40 °C to +70 °C and IK10 impact resistance suit temporary and permanent mast installations on active sites. The 250 m IR range covers haul roads, equipment yards, and site entry points where reliable night coverage over long distances is required.
Large Commercial Car Parks
A single SD6CE445GB-HNR mounted at height can scan an entire multi-bay car park using patrol tours and idle scan patterns. Vehicle and human classification reduces false alarms from passing headlights, while the Starlight sensor retains colour footage under low-level car park lighting conditions.
Correctional and Detention Facilities
The combination of loitering detection, people gathering alerts, and face detection with attribute extraction supports monitoring of exercise yards, entry zones, and perimeter fences. The 300 preset positions allow thorough coverage of a facility layout without operator repositioning for routine monitoring tasks.
Choosing the Right Model
- Choose this model if: Your site requires a single camera to cover a large outdoor area with 45x optical zoom reach, automated subject tracking, comprehensive perimeter analytics including fence climbing and people gathering detection, and IR illumination out to 250 m – all with PoE+ connectivity and extreme weather tolerance.
- Choose a different model if: Your monitoring zone is compact enough to be covered by a fixed or varifocal camera, as PTZ cameras of this class are sized and priced for wide-area deployment rather than close-in fixed positions. If 4K resolution is a project requirement, a higher-resolution PTZ unit should be evaluated. Buyers should also confirm current availability with their supplier, as this model has been listed as superseded.
FAQs
- What optical zoom range does the SD6CE445GB-HNR provide, and what does that mean for scene coverage?
The lens covers 3.95 mm to 177.75 mm, delivering a 45x optical zoom ratio. At the wide end, the horizontal field of view is 65.7 degrees, which suits broad scene orientation. At full telephoto, the field narrows to 1.9 degrees horizontally, allowing the camera to identify subjects at a DORI identify distance of 245.2 m from the mounting point.
- How does Auto-Tracking 3.0 work with the perimeter detection rules?
When an IVS rule such as tripwire or intrusion fires, linkage tracking instructs the camera to pan and tilt toward the detected subject and then follow it using Auto-Tracking 3.0. The camera continues tracking autonomously until the subject leaves the scene or the operator takes manual control. This reduces the need for an operator to be watching the feed at the exact moment an event occurs.
- What perimeter protection rules are included in the SD6CE445GB-HNR?
The confirmed IVS rules are tripwire, intrusion, climbing fences, loitering detection, abandoned object detection, missing object detection, fast moving, parking detection, and people gathering. Vehicle and human alarm classification runs alongside these rules to filter alerts by target type, and linkage tracking connects rule triggers directly to camera movement.
- Does the SD6CE445GB-HNR require a PoE+ switch, or can it run on standard PoE?
The camera requires PoE+ (802.3at), which supplies up to 30W per port. Standard PoE (802.3af) provides only 15.4W and cannot reliably power this unit, particularly at maximum consumption of 25W. If PoE+ switching is not available, the camera can alternatively be powered by a 24VDC 2.5A supply.
- How far do the IR illuminators reach, and does zoom level affect IR performance?
The 6 built-in IR LEDs reach 250 m. Smart IR control adjusts the intensity of the illuminators as the optical zoom changes, preventing the centre of the image from being overexposed when the camera is zoomed in to a close subject. This means the IR is usable across the full zoom range rather than only at wide angle.
- What local storage options are available on the SD6CE445GB-HNR?
The camera supports a Micro SD card up to 512 GB for onboard recording, which provides a useful buffer in network interruption scenarios. Remote storage via FTP and NAS is also supported for sites with centralised recording infrastructure. The camera does not include an integrated HDD bay, so NVR or NAS-based recording is the primary approach for long-term retention.
- What protection does the SD6CE445GB-HNR offer against lightning and electrical surges?
The unit carries TVS 8000V lightning protection alongside surge protection and voltage transient protection. This is particularly relevant for cameras mounted on elevated poles or masts in open areas where direct or induced lightning strikes on cabling are a genuine risk. IP67 sealing also prevents water ingress at exposed outdoor mounting positions. Security Wholesalers supplies this camera as part of the Dahua Pro AI range for sites with demanding environmental requirements.
