What
is an Auto Iris?
The
Auto
Iris is electronically controlled. This allows the camera to
maintain the
lighting level by changing the spatial dynamic of the iris to obtain
optimal
quality imaging. It is applicable in situations where lighting
conditions vary
continuously. An auto iris allows the camera to adjust to get the best
picture
in a given lighting condition. The Auto Iris can be applied to both
fixed and
varifocal lenses.
The
Auto Iris feature is highly flexible in producing consistent
video signals as it can adjust to drastically changing light levels. An
electronically controlled iris is perfect to maintain one consistent
light
level making them ideal for outdoor use or any other applications.
What
is Auto Electronic Shutter?
AES
- (Automatic Electronic Shutter)
allows
the shutter speed to change with response to the amount of perceived
light to
keep the signal output at the best possible level. AES allows an iris
to adapt
automatically to different lighting conditions. When the shutter speed
increases, the light passing through the lens is decreased and the
cameras
sensitivity is reduced. When the shutter speed is decreased, a larger
amount of
light enters the iris. For fast moving objects the shutter speed can
also be
increased to provide a freeze effect in order to provide higher
resolution
images.
In
this particular model, an Auto Electronic Shutter has been
combined with an Auto Iris to provide even higher quality light control.
What
is Auto Tracking White Balance?
White
Balance allows the camera to adjust the tone according to the color
temperature of the light source illuminating the subject. It allows the
operator to see objects as they appear during daylight. Simply put, AWB
is another image amplification feature designed to bring out the best
qualities of the images provided by your camera.
WDR
Function (Wide Dynamic Range)
The
highly accurate signal is
automatically processed to optimally capture the detail in both the
high and
low light areas of the scene simultaneously, maximizing the information
visible
in the picture.
What
is a Removable IR Cut Filter?
This
day and night camera delivers colour images during the day. As light
diminishes below a certain level, it can automatically switch to night
mode to make use of near infrared (IR) light to deliver high-quality,
black and white images. Near-infrared
light, which spans from 700nm to 1000nm, is beyond what the human eye
can see, but this camera sensor can detect it and make use of it.
During
the day, a day/night camera uses an IR-cut filter. IR light is filtered
out so that it does not distort the colours of images as
the human eye sees them. When the camera is in night mode, the IR-Cut
filter is removed, which allows the camera's light sensitivity to reach
down to low lux levels!
What
Does Vari-Focal Lens Mean?
This
camera is equipped with a vari-focal lens, meaning its focal
length can be adjusted anywhere between its designated range. The Focal
Length
determines the field of vision. The smaller the focal length, the wider
the
field of vision. Take a look at the images below. Look how the
church seems
to zoom in as the size of the lens is changed.
The
camera is the same distance from the church in each photo. A
person can zoom in on the subject. Notice the sides of the street show
less the
more the camera zooms.
The
principle is to adjust for the greatest amount of zoom effect,
and therefore the most detail, and still cover the width of the field
of vision
desired.
Below,
the photos shows the actual width of the field of vision at
different lens settings but at the same distance.

TV Lines for Clearer Resolution
TVL
(or TV Lines) is defined as the maximum number of alternating light and
dark lines that can be resolved. A resolution of 400TVL means that 200
distinct dark lines and 200 distinct white lines can be counted over a
horizontal span equal to the height of the picture.
So
what does this mean to you?
In a
nutshell,
more TV
lines means higher resolution, and better picture quality! With that
said, you can feel confident in choosing this camera because it will
provide you with consistent high quality images!
