Yes. The Sensor emits a visible LED flash with every picture taken. This is done for two reasons:
- The LED’s provide illumination for low ambient light settings. The flash increases as the ambient light decreases. The usable distance of the flash in the dark is around 10-12 feet.
- The LED’s are also a security feature to indicate when any picture is taken. That way you will know when the Sensor is taking pictures, even in high ambient light.
