Audio and Visual
AUDIO ONLY
All audio equipment has the function of obtaining any auditory evidence/phenomena.
Some of the equipment used are:-
Digital Voice Recorders…
Both in WAV or MP3 format... for high to low quality audio recording
We will endeavour to always record in WAV format to preserve realistic sound evidence. We will enhance certain sounds just for clarification - but will preserve the 'as-is' raw-file data accordingly.
VISUAL ONLY
For use in capturing ‘visual’ evidence/phenomena. These can be of 'visible', 'infrared nightvision' or 'UVIR' formats.
Some equipment used are:-
Digital Cameras…
For photographic surveys of venues and to possibly capture any visual evidence.
AUDIO and VISUAL
A combination of the above to include the following:-
HD 'NightShot' Camcorder...
With wide-angle lens where required and facility for 'nightvision' mode using Infrared illuminators
HD 'UV-VIS-IR' Camcorder...
With wide-angle lens where required and modified for potential "full-spectrum" capability. That is to see into deeper Ultraviolet, Visible and deeper Infrared light spectrum.
As with Audio evidence, we will always preserve the original unaltered raw-data files accordingly before any enhancements or edits are made for clarification.
Olympus Digital Voice Recorders...
Digital Compact Cameras...
HD Digital Camcorders...
NOTE: The term "Full-Spectrum" is in fact not entirely true. Removing the filter lenses allows more IR and UV light to enter into the camera - thus emphasizing or deepening the opposite ends of the light spectrum.
MOTION SENSOR / TIME-LAPSE
A great piece of kit - new to our arsenal:-
HD Trail Camera/Video 'Nightshot'...
Wide-angle lens incorporating 'motion-sensing', 'time-lapse' and audio - which takes 3 rapid photos before shooting video once motion has been detected.
Can also be used as a point-and-shoot camera.
HD Trail Camera...
LIGHTING / ILLUMINATION
Any camera or camcorder using night vision is not worth anything with mediocre illumination when in darkness. So it is best to add more IR light to your arsenal for illuminating the darkness.
But also the type of nightvision equipment you have will account for the type of illumination you can use.
Full Spectrum...
UV-VIS-IR - what is commonly called "full spectrum" equipment (that it has the filter lens removed to allow IR and UV light into the aperture of the camera/camcorder) can pick up Infrared and Ultra Violet light even more and so can make out more than a standard unit.
These give off a purple-ish glow on the view screen as it is allowing a wider spectrum of light.
Infrared Lights...
These can range from 2 x 10mm LEDs upto 90 x 5mm LEDs in a variety of units and construction. Also some run on 9 volt power whereas other run on 12v (DC power or battery).
Standard 'nightvision' can only use Infrared - usually around the 850nm output. Some equipment are calibrated to pick up 940nm and beyond. So be careful and check what your equipment can pick up.
