Firmware User Manual

Exposure / White Balance

The section Exposure / White Balance allows the user to configure Exposure

(shutter, iris and gain control) and White Balance settings. In most cases, the default settings are

sufficient and no adjustment is needed. Some options will only appear under certain Exposure / White

balance modes. Each mode is described in detail below.

IR Exposure Compensation – Enabled

IR Exposure Compensation is available on all cameras with IR lLEDs. 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.
