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.

Hikvision DS-2CD2643G2-LIZS2U is a 4-megapixel bullet AcuSense camera with a 2.8–12 mm motorized varifocal lens and Smart Hybrid Light technology. AcuSense intelligent classification distinguishes people and vehicles from other objects, significantly reducing the number of false alarms. Hybrid illumination (IR and white) with four operating modes provides color imaging at night at the operator's discretion. A dual built-in microphone and wide dynamic range of 120 dB make the camera a versatile tool for professional security systems.
Advantages
- AcuSense classifies people and vehicles in real time, reducing the workload on security operators
- Smart Hybrid Light (IR + white illumination) provides color recording at night without additional floodlights
- The 2.8–12 mm motorized lens allows changing the field of view remotely via NVR or software
- WDR 120 dB preserves details in both bright and dark areas simultaneously
- A dual built-in microphone provides audio recording with high sound quality
- 4 illumination modes give operational flexibility when surveillance conditions change
Applications
- Guarded areas and checkpoints — intelligent intrusion detection with object classification
- Shopping malls and business parks — color night surveillance with precise alarms
- Outdoor areas of residential complexes — perimeter protection with a low number of false triggers
- Logistics terminals — control of traffic flows and pedestrian zones
