Field of view and DORI distances
The angles come from the manufacturer’s documentation for this model. A level’s distance is how deep along the camera axis the required pixel density holds; in practice the result also depends on light, viewing angle and video compression. The values may differ from the DORI in the datasheet: manufacturers calculate it by their own method, here it strictly follows the IEC 62676-4 density thresholds.

Dahua SD6AL445GB-HNV-IR is a professional network PTZ camera with 45x optical zoom, 4 MP resolution and powerful IR illumination range up to 300 m. Starlight technology provides a detailed image in minimal illumination, while the high IP67 protection rating makes the camera suitable for operation in extreme conditions. This is a solution for facilities where it is critical to monitor large distances — perimeter protection, airports, critical infrastructure.
Advantages
- 45x optical zoom allows clearly examining objects at very large distances without loss of quality
- IR illumination with a range of 300 m provides night surveillance over extended open areas
- 4 MP resolution at high zoom makes it possible to identify targets at distances unattainable for standard cameras
- Starlight technology provides a clear image in low light without activating IR mode
- IP67 protection rating means complete protection from dust and resistance to short-term immersion in water
- The 1/2.8-inch STARVIS sensor provides high light sensitivity for professional applications
Applications
- Protection of airports, ports and large industrial zones with a long perimeter
- Video surveillance at critical infrastructure facilities: power plants, water intakes, pipelines
- Control of the state border and strategic facilities
- Monitoring of large open areas: stadiums, squares, transport highways
