Dahua SD5A432GB-HNR 4MP 32x Starlight IR Network PTZ Camera

The Dahua SD5A432GB-HNR is a professional 4MP Starlight IR Network PTZ Camera designed for demanding surveillance environments where wide-area coverage, long-distance viewing and intelligent target tracking are important. It combines a 1/2.8-inch 4MP CMOS sensor with powerful 32× optical zoom, up to 150-metre IR illumination, 360-degree endless pan movement and advanced WizSense intelligence.

Dahua SD5A432GB-HNR 4MP 32x Starlight IR PTZ Camera

With a maximum resolution of 2560 × 1440, 32× optical zoom and a 4.8–154mm motorised lens, the SD5A432GB-HNR can provide detailed views across large surveillance areas. Its Starlight imaging technology helps maintain useful colour and monochrome footage under low-light conditions, while the long-range IR system supports night-time monitoring.

The camera also incorporates Auto Tracking 3.0, SMD 4.0, face detection and perimeter protection features. These capabilities make it suitable for applications where simply recording video is not enough and operators need intelligent assistance for detecting, following and investigating people or vehicles.

Powerful 4MP Starlight Imaging

The 4MP progressive-scan CMOS sensor delivers images up to 2560 × 1440 resolution. The Starlight design provides improved low-light sensitivity, with minimum illumination rated at 0.005 lux in colour mode and 0.0005 lux in black-and-white mode at F1.6. When the IR illuminator is active, the camera can operate down to 0 lux illumination.

This combination is useful for security locations where lighting conditions change throughout the day. The camera can provide detailed daytime footage while continuing surveillance after dark without depending entirely on external lighting.

32x Optical Zoom for Long-Distance Surveillance

The 32× optical zoom is one of the most important features of the SD5A432GB-HNR. Its 4.8mm to 154mm focal-length range allows the camera to move from relatively wide scenes to tightly framed distant subjects without relying on digital enlargement alone.

The wide-end horizontal field of view reaches 55.8 degrees, while the telephoto view narrows to 2.4 degrees. This makes the camera suitable for monitoring expansive locations and then concentrating on a distant person, vehicle or other point of interest.

150 Metre IR Night Vision

The built-in IR system provides an illumination distance of up to 150 metres. Smart IR and zoom-priority illumination help manage infrared output as the camera changes its viewing angle and magnification.

This long-range night vision capability is especially useful for large outdoor properties, perimeter areas, industrial sites, transport facilities and other locations where conventional fixed cameras may not provide sufficient coverage.

PTZ Movement and Preset Control

The camera supports 0 to 360-degree endless pan movement and a tilt range from -15 to +90 degrees, with automatic 180-degree flip. This allows a single PTZ camera to monitor a broad area while giving operators the ability to reposition the lens when an event occurs.

WizSense AI Surveillance

The SD5A432GB-HNR belongs to Dahua's WizSense range and uses intelligent algorithms designed to focus surveillance events on relevant human and vehicle activity. This can help reduce the amount of irrelevant footage that operators need to review.

SMD 4.0 provides intelligent motion detection with target classification, while perimeter protection features can support applications such as tripwire, intrusion, loitering, fast-moving object and parking detection.

Auto Tracking 3.0

Auto Tracking 3.0 enables the PTZ camera to automatically follow suitable targets within supported surveillance scenarios. Instead of requiring an operator to manually control the camera throughout an event, the intelligent tracking function can assist with maintaining the subject within the viewing area.

This is particularly useful for large compounds, entrances, perimeter zones, industrial facilities and other environments where suspicious movement may occur across a wide area.

Advanced Face Detection

The camera supports face detection with face bounding boxes, snapshot capture, face image enhancement and attribute extraction. Supported attributes include characteristics such as gender, age, glasses, mask and moustache, along with expression analysis.

These functions can help security personnel locate relevant footage more efficiently when investigating incidents. Actual performance depends on lighting, subject distance, camera positioning, movement and other environmental conditions.

Long-Range DORI Performance

The manufacturer's DORI figures indicate substantial long-distance detection capability when the camera is appropriately positioned and the optical zoom is used effectively.

DORI values are reference measurements rather than a guarantee that every scene will produce the same result. Actual identification performance can vary with lighting, target size, movement, atmospheric conditions, installation height and camera settings.

Built for Outdoor Surveillance

The SD5A432GB-HNR is designed for demanding outdoor applications. Its IP67 protection helps protect the enclosure against dust and water ingress, while the IK10 rating provides a high level of resistance against mechanical impact.

The camera is rated for operation from -40°C to +70°C with humidity up to 95%. Additional protection includes TVS 6000V lightning protection, surge protection and voltage transient protection.

Network Connectivity and PoE+

The camera features a 10/100 Base-T RJ45 network interface and supports PoE+ based on IEEE 802.3at. This can simplify installation by allowing compatible network infrastructure to provide power and data connectivity through Ethernet.

It also supports ONVIF Profile S, Profile G and Profile T, along with CGI and SDK integration. This provides flexibility when integrating the camera into compatible IP surveillance systems.

Local Storage and Remote Management

The SD5A432GB-HNR supports Micro SD card storage up to 512GB, as well as FTP and NAS storage options. This provides additional flexibility for recording and backup requirements.

Dahua management platforms including SmartPSS, DSS, DMSS and IVSS can be used with the camera, while Android and iOS mobile clients provide convenient remote monitoring options.

Two-Way Audio and Alarm Integration

The camera provides one audio input, one audio output and two-way audio functionality. It also includes two alarm inputs and one alarm output, allowing suitable external devices to be integrated into the surveillance system.

Alarm linkage can trigger actions such as preset positioning, tours, patterns, recording, snapshots, email notifications and other configured responses. This makes the camera suitable for more advanced security installations rather than basic video monitoring alone.
