The Dahua HAC-HDW1000R is a 1MP Dome-type camera designed for surveillance purposes. Here are some of its key features:

1. Resolution: It offers a 1MP resolution (1280x720), which provides clear and detailed images suitable for general surveillance needs.

2. Dome Design: The camera's dome design is typically used for indoor or outdoor mounting on ceilings, providing a discreet appearance and preventing the camera from being easily tampered with.

3. Infrared Night Vision: It is equipped with IR LEDs, allowing the camera to capture clear images even in low-light or no-light conditions. The typical range for night vision in this camera is around 30 meters (98 feet).

4. Housing and Durability: It has a weather-resistant and durable housing, making it suitable for both indoor and outdoor use. The camera is often rated with an IP67 (dust-tight and protected against temporary immersion in water).

5. Compression Technology: The camera uses HDCVI (High Definition Composite Video Interface) technology, which allows for high-definition video transmission over coaxial cables. This is a great option for retrofitting older CCTV systems.

6. Wide Dynamic Range (WDR): The camera features WDR, which helps to balance lighting in scenes with both bright and dark areas, improving visibility and detail.

7. Lens and Field of View: It typically comes with a fixed lens, offering a broad field of view suitable for monitoring areas such as hallways, parking lots, and small open areas.

8. Power Supply: The camera uses a standard 12V DC power supply, which is common in security camera systems.

This camera is an ideal choice for small to medium-sized installations where high-quality surveillance footage is needed. It provides a balance between affordability and functionality, particularly for installations in both residential and commercial settings.
