Can you use a digital night vision scope during the day?

Yes. A CMOS-based digital night vision scope can use daylight and reflected scene light to form an image. Daylight often gives the sensor more signal, but the device remains the same digital imaging system after sunset. Image quality changes with available light, contrast, focus, target reflectivity, and settings.

Must IR be turned on for night viewing?

No. In moonlight or another usable low-light condition, a digital night vision scope may form an image without IR. The image may be darker or less detailed. IR is useful when the available signal is too weak, but it is an aid rather than a universal requirement for nighttime operation.

Does a 3 W IR illuminator guarantee a clear image?

No. Power is only one part of the result. Beam pattern, target reflectivity, distance, focus, atmosphere, obstruction, sensor performance, and display settings also matter. The DH9’s integrated 3 W laser IR illuminator is designed to provide adjustable low-light assistance, not to guarantee the same image in every scene.

Does the same imaging system work in both daylight and low light?

Yes. The DH9 uses the same CMOS-based imaging chain across changing light conditions. What changes is the amount of usable scene light and whether infrared assistance is helpful.

What affects image quality as daylight fades?

Available light, target contrast and reflectivity, focus, weather, device settings, and the use of infrared assistance can all affect the displayed image.
