Night Vision Camera

Elite hunting night vision goggles & night vision camera -- Maximizes the nighttime sensitivity of the camera lens as well as giving the user complete control of exposure compensation in order to let you take the best possible at night. Excellent for hunting, camping, military & spy applications. Share these high def night vision images with your friends using the easy share feature.

Another great feature is a built in LED Flashlight torch. Allows you to easily control (turn on and off) the LED Flash on your phone to use it as an excellent flashlight tool for seeing in the dark. This is a very high quality and reliable LED flashlight

DISCLAIMER: This app increases lens light sensitivity to its maximum. Since android devices do not have a real night vision/infrared sensor; for this reason it will not compare to a true professional night vision/thermal imaging device like those used by CIA, NSA, FBI, KGB, MI6 (and no apps ever will). This app does maximizes the night time potential of your android device to the maximum extent allowed by the hardware but is not perfect since these devices do not include a thermal vision sensor.

- A night vision device (NVD) is an optical instrument that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to civilian users. The term usually refers to a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, and some type of mounting system. Many NVDs also include sacrificial lenses,[1] IR illuminators, and telescopic lenses.

- Infrared (IR) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 mm. This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz.[1] Most of the thermal radiation emitted by objects near room temperature is infrared.

- Night vision is the ability to see in low light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range. Humans have poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum
