Performance curves versus Temperature
¾
These curves have been established with a 4k Pixel Camera (worst case).
¾
The “Camera Temperature” is given by the internal Sensor of the Camera.
¾
All the values in LSB are in 12 bits
Darkness Noise vs Temperature : For both Min an Max preamp Gain values
Darkness Noise vs Temperature : Detailed curve for the Min preamp Gain value
The Cameras tuning is done in factory after a certain time of warm up (close to a “normal condition of
use) in order to ensure that the Camera will give its best while runing 24h a day. This explains a slight
decreasing of the noise when the temperature rises up.
