near IR night vision devices for seeing wildlife

see also:

  • do not look into IR illuminators at close range it may damage your eyes
  • do not aim IR illuminators at combustible materials at close range
  • IR cameras detect reflected IR light in wavelengths shorter than 1µm (eg. 850 or 940nm IR lamps)
  • on nights with a full moon, their benefit is largely restricted to the viewing shadow areas as naked eye sight will do pretty well on full moon lit subjects
  • thermal imaging devices detect subject radiated heat with IR wavelengths of 7-14µm which is VERY DIFFERENT technology and these have MUCH lower resolution but can measure temperature

Introduction to near IR night vision cameras (not thermal imaging cameras)

  • these require a near IR light source illuminating the subject which may be either:
    • daylight (digital only - daylight may destroy analog II devices)
    • moonlight
    • 850nm IR illuminator
    • 940nm IR illuminator (digital only)
  • near IR night vision devices may use one of the two different technologies:
    • digital camera sensor sensitive to IR light and no IR blocking filter
      • these can usually also record camera images and/or video to a memory card (usually 1080 or 720p)
      • most have a digital zoom option
      • some can be remotely controlled by WiFi
      • can generally use 940nm IR illuminators as well as 850nm
      • most are monochrome (usually green or gray scale) but some give colour imagery at night
    • analog image intensifier (II) tube technologies
      • much less power consumption than digital
      • newer ones still generally have higher resolution than current digital ones
      • II tube has less life span and efficiency falls over time - perhaps 5-10yrs
      • II tube will be destroyed if exposed to daylight
      • generally cannot use IR illuminators above 850nm (ie animals will see it)
      • lower end models are more sensitive to rifle recoil than digital
      • cannot record stills or videos
      • give monochrome green images (except for those with White Phosphor Technology (2QS and 3G) which give gray scale images)
      • Gen 0 - those developed prior to end of WWII
      • Gen 1 - those developed by US army for the Vietnam war and used a S-20 photocathode, their image intensifiers produced a light amplification of around 1000 but still require at least moonlight or IR illuminator (usually around 790nm)
      • Gen 2 - developed in the 1970's with improved image-intensifier tube using micro-channel plate (MCP) with an S-25 photocathode, which gave light amplification of around 20000, improving resolution and reliability; Useful range is generally up to 200m; Life expectancy is about 5,000 hours of use;
      • Gen 3 - developed in the late 1980's used MCP but now with used a photocathode made with gallium arsenide, light amplification is also improved to around 30000–50000, but required more power and had large halo effect; Sufficiently efficient not not require an IR illuminator or moonlight; Useful range is generally up to 300m; Life expectancy is over 10,000 hours of use;
      • Gen 3+ “3AG” “Gen IV” - developed in the 2000s with autogated tubes
  • most have an IR illuminator which can be turned on to vastly improve the image quality up to a reasonable distance - usually several hundred metres - depending upon IR wavelength which will also determine how discrete and invisible this illuminator is to the wildlife with the 940nm ones being the most discrete but least powerful in terms of distance and generally need a sensor with high sensitivity in the range of 900-950nm
  • some have a Picatinny Rail Mount to mount other devices such as an additional IR illuminator
  • these IR night vision devices are NOT designed as photographic tools - they generally have limited manual photographic controls and have relatively poor focus supports, no image stabilisation and relatively low level of image detail
    • if you want a photographic tool you will be better off using a large sensor mirrorless camera with IR blocking filter removed, but these are much bigger, heavier and more expensive
  • they are designed to visualise an animal in the dark and if it is close enough ascertain what type of animal it is and how it is behaving
  • at further distances, you may only see the animal's eyes
  • they are also very useful for detecting IR light sources
  • for the paranoid community, users will NOT be able to see into a dark room through a window from a distance even with a reasonably powerful IR lamp but they could do from a close distance of less than 10-20m

IR illuminators

  • as with all light, the intensity of these lights decrease by a quarter (2 ISO stops in other words your will need an ISO 4 times higher) every time you double the distance from the lamp - the inverse square law
    • this also means foreground foliage will generally be very over-exposed and may cause your subject to be under-exposed significantly with automatic exposure digital devices - you can address this via:
      • using a digital camera with manual exposure controls, or,
      • using your IR lamp off-axis so it doesn't hit the foreground foliage
  • animals will easily see 850nm lamps and will generally be scared off
  • humans can still see 940nm lamps especially if they are zoomed in and aimed at the human
  • humans and animals cannot see the light on the scene from these IR lamps

IR blocking safety glasses

  • in case you are using IR or red (usually 635-660nm) lasers you may want protective glasses (most are around $AU230-270) such as:
  • NB. these safety glasses will generally reduce your night naked eye vision as they have lower visual transmissions and of course they will stop you seeing the laser beam!
