Unlike traditional night vision devices that rely on intensifier tubes, digital night vision can capture and display images in real-time on a screen. This technology often offers features such as adjustable brightness, color modes, and the ability to record or capture images. Digital night vision devices are typically more compact, lightweight, and versatile compared to traditional night vision goggles. **
