Alongside a classic pair of BAK4 7x50 binoculars with IPX7 protection you will find thermal monoculars and digital night vision devices with 4K recording. A thermal image shows differences in heat and works in complete darkness, whereas a digital night vision device needs at least a little light. Compare the sensor resolution and the field of view — 640x512 gives noticeably more detail than 384x288.
