Night Vision Goggles for Surveillance Investigations in Dark Environments
Night vision binoculars (also called night vision goggles), scopes and weapon sights provide the ability to see in a dark environment. Night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range.
Private investigators and police officers may use night vision binoculars, goggles, scopes and weapons sights while conducting night time surveillance investigations to view the activity of their subject. Many secret relationships and marital infidelity takes place overnight, so this equipment is critical to catching subjects while they are active.
The goal of using such a device is to see clearly in the dark while others have trouble seeing. The physical device consists of an infrared image intensifier tube in a rigid casing, commonly used by military forces.
Example of ways the device can be used include: Distance observation, surveillance missions, subject tracking, hiking, camping, cave exploration, commercial and sport fishing, law enforcement search and rescue
The night vision goggle is a night vision device with dual eyepieces; the device can utilize either one intensifier tube with the same image sent to both eyes, or a separate image intensifier tube for each eye. Other types of binoculars include monocular night vision devices with only one eyepiece which may be mounted to firearms as night sights. Note, these are sometimes referred to as infrared binoculars.
Following are some of the features that can be found on various devices:
