The Dahua DH-IPC-HDW3666EMP-S-AUS is a 6MP IP camera manufactured by Dahua Technology, a leading provider of video surveillance products and solutions. This camera model offers advanced features and high-resolution imaging capabilities. Here are some key details about the Dahua DH-IPC-HDW3666EMP-S-AUS:

Resolution: The camera has a 6-megapixel (3072 x 2048 pixels) resolution, providing sharp and detailed video footage.

Image Sensor: It utilizes a progressive scan CMOS sensor, which helps capture clear images even in challenging lighting conditions.

Lens: The camera is equipped with a fixed lens that provides a specific focal length for capturing the desired field of view. The exact specifications of the lens may vary depending on the specific model.

Video Compression: It supports efficient video compression formats like H.265+ and H.264, which reduce bandwidth usage and storage requirements while maintaining video quality.

IR Illumination: The DH-IPC-HDW3666EMP-S-AUS features built-in infrared (IR) LEDs, allowing for clear surveillance even in complete darkness. The IR range may vary depending on the specific model.

Weather Resistance: This camera is designed to withstand various weather conditions. It typically has an IP67-rated weatherproof housing, making it suitable for both indoor and outdoor installations.

Smart Features: The camera may include advanced features such as motion detection, tamper detection, face detection, and other intelligent video analytics capabilities.

Network Connectivity: It supports Power over Ethernet (PoE) for simplified installation and network connectivity. It can also be connected to a local network via Ethernet or wirelessly using Wi-Fi (if the specific model supports it).

Video Management Software: Dahua cameras are often compatible with Dahua's video management software (VMS) and can be integrated into larger surveillance systems for centralized monitoring and management.

It's important to note that while the information provided here is accurate as of my knowledge cutoff in September 2021, specific details or updated features may have been introduced by Dahua Technology since then.

Series Overview

Dahua WizSense 3 Series Network Camera greatly saves on bandwidth and storage space through its AI Coding technology. Driven by its advanced deep learning algorithms, the camera supports intelligent functions such as perimeter protection, smart motion detection (SMD), Quick Pick, and AI SSA (AI Scene Self-adaptation), making it easy and convenient to use. Starlight technology and its large aperture lens also allow the camera to produce clear, vivid images even in poor lighting conditions.


SMD 4.0

Dahua Smart Motion Detection technology works with intelligent algorithms to classify targets that trigger motion detection alarms. It f ilters out objects that are not targets, such as small and large animals, to avoid triggering false alarms. With an AI NVR, Quick Pick technology becomes available, allowing you to easily search for and pick out human and vehicle targets from SMD event videos, prioritizing the highest matches.


Dahua AI Scene Self-adaptation (AI SSA) adopts deep learning algorithms to detect environmental conditions, such as rain, fog, backlight, low light and flicker, to adjust the parameters of the image to suit the conditions, ensuring that clear images are always produced.

Smart H.265+ & Smart H.264+

With advanced scene-adaptive rate control algorithm, Dahua smart encoding technology realizes the higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces the cost of storage and transmission.

Protection (IP67, Wide Voltage)

IP67: The camera passes a series of strict test on dust and soak. It has dust-proof function, and the enclosure can works normal after soaking in 1 m deep water for 30 minutes. Wide voltage: The camera allows ±30% (for some power supplies) input voltage tolerance (wide voltage range), and it is widely applied to outdoor environment with instable voltage.

Cyber Security

Dahua network cameras employ a series of security technologies, including security authentication and authorization, access control protocols, trusted protection, encrypted transmission and encrypted storage. These technologies improve the camera's defense against external cyber threats and prevent malicious programs from comprising the device.
