IR Exposure Compensation – Enabled
IR Exposure Compensation is available on all cameras with IR LEDs. This feature automatically
balances the IR exposure to eliminate over-exposed images cause by too much IR on the subject.
When enabled, the AE reference target is automatically adjusted to control the sensor’s shutter
speed and gain to compensate IR effect.
Exposure Mode - Auto
In Auto Exposure Mode, you control the image brightness by configuring the AE Reference
Target and Slowest Auto Shutter.
AE Reference Target (Auto Exposure reference target) can be considered as the “Target
Brightness on Sensor”. The camera will use several internal parameters to achieve best quality
with reference to this. The higher this value, the brighter the overall scene, however, there
may be more noise at night in such case. The range of AE Reference Target is 1~255.
The camera will automatically control shutter speed, auto iris (if available) and signal gain to
achieve the target level set by the user. If the auto iris does not exist or is already opened to a
maximum size, and the image is still darker than the user defined target, it will further slow down
the shutter speed within the allowed range (set by user under Slowest Auto Shutter Speed) and
increase the signal gain.
