Rating Camera Performance is a whitepaper by Infiniti Electro-Optics
The DORI (Detection, Observation, Recognition, Identification) standard is based on the IEC EN62676-4: 2015 International Standard. Unlike DRI (also known as the Johnson Criteria) for thermal cameras, DORI is designed for visible light surveillance cameras and uses specific measurements in PPM (Pixels Per Meter) to define what Detection (25PPM), Observation (62PPM), Recognition (125PPM), and Identification (250PPM) are for standard color cameras. By using these PPM values, it is possible to select a specific camera sensor/lens combination and verify that it will provide the performance needed in each application based on the criteria given above.
Rating Camera Performance contains the following major sections:
- Long-Range Factors
- Pixels Per Meter
- DRI & DORI Explained
- DRI Ratings Explained
- DRI Detail Levels
- Alternate Methods
- DORI Ratings Explained
- DORI Detail Levels
