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 SD4E425GB-HNR-A-PV1 is an intelligent WizSense series PTZ camera with 4 MP resolution, 25x optical zoom and Starlight technology for nighttime operation. Automatic target tracking based on deep learning algorithms allows the camera to independently follow moving objects without operator involvement, which is especially valuable for protecting facilities with limited staff. IR illumination up to 100 m and IP66 protection ensure reliable operation in any outdoor conditions.
Advantages
- Automatic tracking based on deep learning allows the camera to independently follow a target without manual control
- 25x optical STARVIS zoom provides high detail at long distances while maintaining clarity
- 4 MP resolution makes it possible to identify faces and vehicle license plates
- Starlight technology provides a quality image even in minimal outdoor lighting
- 100 m IR illumination covers a large monitoring zone in night mode
- WizSense intelligence reduces the number of false alarms by distinguishing people, vehicles and other objects
Applications
- Protection of facilities with high response requirements: banks, jewelry stores, data centers
- Monitoring of large open areas with automatic tracking of intruders
- Perimeter control of industrial enterprises and restricted facilities
- Video surveillance at logistics complexes with nighttime traffic
