Product SKU: DH-SD1A404XB-GNR
Product Overview
Compact PTZ cameras often sacrifice intelligence for size, but the Dahua DH-SD1A404XB-GNR combines a 4x optical zoom range with on-board AI analytics in a housing rated IP66 and IK08, making it a strong candidate for monitored entry points, small open yards, and perimeter zones where a fixed camera cannot adapt to changing conditions. Built around a 1/2.8-inch 4MP STARVIS CMOS sensor with Starlight technology, this unit maintains usable colour detail in near-dark conditions before switching to IR illumination with a range up to 15m. The 2.8mm to 12mm motorised varifocal lens delivers flexible framing at commissioning and allows operators to zoom in on activity without repositioning the mount. AI-driven capabilities including Perimeter Protection, Face Detection, and People Counting, combined with Smart Motion Detection, reduce the volume of non-essential alert traffic. With PoE support, WDR, and auto ICR, the DH-SD1A404XB-GNR suits commercial sites requiring adaptable coverage in a compact PTZ form factor.
Key Capabilities
4x Optical Zoom
The 2.8mm to 12mm motorised varifocal lens allows installers to set the field of view precisely at commissioning and gives operators the ability to zoom in on an area of interest without physically repositioning the camera, covering both wide entry views and tighter detail shots from a single mount point.
Starlight Low-Light Imaging
Dahua Starlight technology extracts colour detail from scenes with very little ambient light before the auto ICR filter switches the sensor to monochrome IR mode. This transition keeps footage readable through dusk and low-light periods without relying entirely on IR illumination, which is particularly useful at covered entry points or low-lit outdoor areas.
AI Perimeter Protection
Perimeter Protection uses CNN deep learning to distinguish people and vehicles crossing defined virtual lines or entering set zones, filtering out irrelevant motion like swaying trees or passing headlights. This reduces nuisance alerts significantly and is suited to small yards, driveways, and access gates where boundary enforcement matters.
Face Detection and People Counting
On-board Face Detection flags when a face enters the scene, supporting post-event search and access review workflows. People Counting tracks entry and exit volumes over time, adding operational value for retail or building management applications beyond basic security monitoring.
IP66 and IK08 Protection
IP66 weatherproofing seals the unit against rain, dust, and wash-down conditions, while the IK08 impact rating means the housing can withstand moderate physical contact. This combination supports outdoor wall or pole mounting in semi-exposed commercial locations without requiring additional enclosures.
Smart Motion Detection (SMD)
SMD classifies detected motion events by subject type, separating human and vehicle triggers from environmental sources. This keeps recording and alert systems focused on events that actually warrant attention, reducing review time and storage overhead compared to pixel-level motion detection alone.
Best For
- Small Commercial Perimeters: The 4x optical zoom and AI Perimeter Protection make this unit well suited to monitoring access gates, small yards, and service entry points where a fixed-lens camera cannot adapt to variable distances.
- Low-Light Outdoor Environments: Starlight technology combined with 15m IR illumination and auto ICR keeps footage usable through dusk and overnight in car parks, walkways, and lightly lit outdoor areas without needing supplementary lighting.
- Retail and Building Entry Monitoring: Face Detection and People Counting add operational intelligence at shopfronts, building lobbies, and entry corridors where both security and traffic data are useful.
- PoE-Powered Installations: With PoE support, the DH-SD1A404XB-GNR draws power directly from the network cable, simplifying cable routing at locations where running a separate power feed would be impractical.
Why Choose the DH-SD1A404XB-GNR
The DH-SD1A404XB-GNR stands apart from fixed-lens 4MP cameras by combining motorised zoom control with a suite of AI analytics in a compact PTZ body that is fully weatherproofed and impact-rated for outdoor deployment. A basic fixed-lens camera at this resolution cannot adapt its field of view after installation or apply scene-aware filtering to reduce false alerts. This model delivers Perimeter Protection, Face Detection, People Counting, and SMD from the unit itself, meaning the analytics load sits at the edge rather than relying entirely on recorder-side processing. The Starlight sensor reduces dependence on artificial lighting in borderline conditions, and IK08 vandal resistance adds durability that typical outdoor dome cameras at this price point may not carry. For installers and integrators looking for a compact PTZ with genuine on-board intelligence at a practical price, the DH-SD1A404XB-GNR is available through Security Wholesalers as part of the Dahua IP PTZ range.
Buyer Tip: The 4x optical zoom on the DH-SD1A404XB-GNR covers a moderate zoom range suited to close-to-mid-distance scenes. If your monitoring zone extends beyond 15 to 20 metres and requires fine facial or plate detail at range, consider whether the 15m IR distance is sufficient for your lighting conditions at night. This model performs best when mounted at 3 to 5 metres in height, covering an area no deeper than the IR throw allows. For very long approaches or wide-area scanning across large open spaces, a higher-magnification PTZ with extended IR would be more appropriate.
Buyer Tip: The People Counting feature operates as an on-device analytic, meaning it generates count data without requiring a dedicated analytics server. However, for accurate counts and meaningful reporting, the camera should be mounted directly above the entry point with an unobstructed downward view of the passage. Mounting at an angle or too far from the entry path will reduce counting accuracy. Confirm mounting position and ceiling height before relying on this feature for operational reporting.

Ideal Use Cases
Access Gate Monitoring
The 4x optical zoom and Perimeter Protection analytics allow the DH-SD1A404XB-GNR to monitor a vehicle or pedestrian gate, zooming in on activity while triggering alerts only when a person or vehicle crosses a defined boundary line.
Small Outdoor Yard or Compound
IP66 weatherproofing and IK08 impact resistance allow wall or pole mounting in open outdoor areas. The motorised zoom can frame the full yard at wide angle or pull in to a specific zone without changing the physical mount position.
Retail Shopfront Entry
Face Detection at the shopfront door supports post-incident review and people counting tracks customer entry volume over time, giving retail operators both security and operational insight from a single camera position.
Low-Light Car Park Entry
Starlight technology extracts colour detail in low ambient light before IR takes over, keeping the entry point visible through the evening transition. SMD filters out vehicle-only triggers if pedestrian alerting is the priority, or can be configured for both.
Building Lobby or Reception
Mounted at ceiling height above a lobby or reception desk, the 4x zoom lets the camera cover the full entrance area at wide angle while offering the ability to frame in on a specific counter or doorway when needed during a live monitoring session.
Choosing the Right Model
- Choose this model if: You need a compact PTZ with on-board AI analytics including Perimeter Protection, Face Detection, and People Counting, combined with Starlight low-light performance and PoE power, for a small commercial outdoor zone or monitored entry point within a 15m IR range.
- Choose a different model if: Your site requires IR illumination beyond 15 metres, significantly higher optical magnification for long-range detail, or continuous 360-degree automated patrol across a large open area. In those scenarios, a larger full-size PTZ with extended IR and higher zoom ratio would provide more appropriate coverage.
- Choose a different model if: Your installation requires a completely fixed-angle view with no zoom adjustment needed after commissioning. A fixed-lens turret or dome camera at 4MP would deliver comparable image quality at a lower cost for that specific scenario.
FAQs
- What does the 4x optical zoom on the DH-SD1A404XB-GNR allow me to do?
The 4x optical zoom moves the lens from 2.8mm wide angle to 12mm telephoto. This means at commissioning you can frame the exact view you need without cutting resolution, and during live monitoring an operator can zoom into a zone of interest. It covers moderate distances well and is suited to yards, entry gates, and open areas of small to medium depth.
- How does Starlight technology differ from standard night mode?
Starlight is a low-light sensor design that maintains colour imaging at illumination levels where a standard camera would switch to black-and-white IR mode. The DH-SD1A404XB-GNR uses this to extend the colour detail window through dusk and into low-light periods. When light drops further, the auto ICR filter activates and the camera switches to monochrome IR using the 15m IR illuminators.
- Is the Perimeter Protection feature set up in the camera itself or does it require recorder-side configuration?
The Perimeter Protection, Face Detection, People Counting, and SMD analytics on the DH-SD1A404XB-GNR are processed at the camera edge. You configure the detection zones and rules through the camera’s web interface or a compatible VMS or NVR that supports Dahua AI event handling. This reduces the processing burden on the recorder for analytics.
- What does IK08 mean for outdoor mounting of this camera?
IK08 is an impact resistance rating that indicates the housing can withstand a defined level of physical force without damage to the optics or internal components. For the DH-SD1A404XB-GNR, this means the unit is suitable for locations where it may be subject to accidental contact, minor vandalism, or vibration, such as a wall mount near a loading area or a busy entry point. It is not rated for deliberate high-force attack.
- Does the DH-SD1A404XB-GNR support PoE, and what does that mean for installation?
Yes, the camera supports Power over Ethernet. A single Cat5e or Cat6 cable carries both network data and power from a PoE switch or NVR with PoE ports to the camera. This eliminates the need to run a separate 12V or 24V power cable to the mounting location, simplifying installation particularly in outdoor locations where adding power points would be costly or impractical.
- What NVR or recorder is compatible with this camera?
The DH-SD1A404XB-GNR is a Dahua IP network camera and is compatible with Dahua NVRs that support ONVIF or native Dahua protocol connection. For AI event handling including Perimeter Protection alerts and SMD triggers, a Dahua NVR that supports AI camera event processing will deliver the best integration. Confirm AI event compatibility with your chosen recorder model before deploying the analytics features. Contact Security Wholesalers to confirm NVR pairing for your installation.
- Is 15 metres of IR range sufficient for most outdoor placements?
For a compact PTZ at this size, 15m IR is appropriate for entry points, access gates, and covered outdoor areas where the camera is mounted at 3 to 5 metres in height. It is not suited to monitoring large open areas or long driveways where targets may be 20 to 30 metres or more from the camera at night. Assess your specific scene depth and ambient lighting before confirming this unit for a long-range night-time monitoring requirement.
