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.

The angles were cross-checked against the manufacturer’s model page and datasheet.

Hikvision DS-2CD20123G2-LIUY/SRB is a 12-megapixel IP camera featuring AcuSense technology and unique red-and-blue strobe illumination that mimics emergency service signals. The built-in audible siren and visual strobe create a powerful deterrent effect for intruders. IP67 protection and the H.265+ codec ensure reliable operation in outdoor conditions with optimal disk space usage.
Advantages
- 12 MP resolution allows wide areas to be covered while still preserving the detail needed for identification
- The red-blue strobe illumination is psychologically associated with police, which enhances the deterrent effect
- AcuSense filters out false alarms, responding only to people and vehicles
- The built-in audible siren complements the light effect without external devices
- WDR 120 dB provides quality video in complex lighting — at entrances washed out by headlights
- IP67 protection allows the camera to be mounted outdoors without an additional protective housing
Applications
- Protection of warehouse and production perimeters with a risk of nighttime intrusions
- Parking lots and open areas with remote monitoring
- Construction sites where physical security is not maintained at night
- Private residences and country properties
