○ Provides clear and detailed high-definition video, suitable for a variety of surveillance applications.

2. Lens: 2.8mm

○ The fixed 2.8mm lens offers a wider field of view compared to a 3.6mm lens, typically covering around 100-110 degrees. This is ideal for capturing a broad area and is useful in scenarios where you need to monitor larger spaces.

3. Infrared Night Vision:

○ LED: Features infrared (IR) LEDs for enhanced night vision capabilities.

○ Range: The night vision range is generally up to 30-40 meters, depending on environmental factors and the effectiveness of the IR LEDs.

4. Weather Resistance:

○ IP67 Rating: The camera is designed to be robust and weatherproof, making it suitable for outdoor use and capable of withstanding harsh environmental conditions such as rain, dust, and extreme temperatures.

5. Compression and Video Encoding:

○ H.265 Compression: Supports H.265 video compression, which is more efficient than H.264. This reduces bandwidth usage and storage requirements while maintaining high video quality.

6. Smart Features:

○ Motion Detection: Can detect movement within its field of view and can trigger alerts or recording based on detected activity.

○ Tampering Alarm: Provides notifications if the camera is tampered with or obstructed.

○ Line Crossing Detection: Alerts when objects cross a virtual line set within the camera’s view.

7. Connectivity:

○ HD-CVI: Uses HD-CVI (High Definition Composite Video Interface) technology, allowing high-definition video transmission over coaxial cables. This is a cost-effective solution for upgrading older analog CCTV systems.

○ Power Supply: Typically requires a separate power supply, though some models may support PoC (Power over Coax) for convenience.

8. Remote Access:

○ Software Compatibility: Can be integrated with Dahua’s software and apps for remote viewing and management of live and recorded footage.

Advantages:

● Wide Field of View: The 2.8mm lens provides a broad view, making it ideal for monitoring larger areas with fewer cameras.

● High-Quality Night Vision: Effective IR night vision capabilities ensure clear footage even in low-light conditions.

● Durable Design: The IP67 rating ensures reliability and longevity in outdoor environments.

● Cost-Effective Upgrade: HD-CVI technology enables high-definition video transmission over existing coaxial cabling, which can be more economical compared to full IP-based systems.

Considerations:

● Fixed Lens: The 2.8mm lens is fixed, meaning you cannot adjust the zoom or field of view. Ensure this lens suits your coverage needs before installation.
