Night Vision4.1. IR lighting4.1.1. DescriptionThe <strong>Video</strong> <strong>Camera</strong> Sensor Board have 22 IR LEDs divided in two blocks controlled each one by transistors, to give extra iluminationand record with few light or in the night. Block 1 can be controlled by pin DIGITAL6 (POWER_LED) and the block 2 by pinDIGITAL8 (POWER_LED2) or using the function powerIRLED(). Please, refer to API chapter for more information.Block 1Block 2Figure 24: IR LED blocksFigure 25: IR LEDs activated4.1.2.
