Frequently asked questions Does the LI2U model include a speaker or active warning? The standard LI2U is positioned around imaging, hybrid illumination and dual-microphone audio capture.

Infrared supports discreet monochrome night viewing, while white light can provide color detail or a visible response. The selected operating mode controls how they are used. What does the dual microphone add? It captures audio with the video stream for compatible recording and live-view systems. Audio use must follow local privacy rules. Can the field of view be changed after installation? This is a fixed-lens family, so select the correct focal length before purchase and verify the scene with a field-of-view calculation.
