General
The extending ni-vision Digital Noise Reduction IR camera offers a complete
IR distance range from 10M~40M. The camera comes in 540TVL, DNR
function and built in IR LEDs with ICR D/N vari-focal lens. Its sophisticated
mechanical design enhanc ed the accessibility and conveniency in terms of
installation. Sturdy and IP66 enclosure ensures the camera to stay in best
condition even under most crit ic al env i r onme nt
The outsta ndi ng ho us ing created for exter nal vari-focal zoom focus adjustment
is convenient for adjusti ng focus fro m rear side. Plus the high torque bracket
for easy 3 axis dir ect ion for installation.
This color CCD video camera employs a 1/3 inch charge coupled device
solid-state imaging device with 470/410 k picture elements , The unit is
equipped with a newly developed DNR DSP (Digital Signal Processor) for
processing the video signal.
The DNR function is a newly developed technology which suppressed all
significant noise while AGC is activated. So the camera is able to deliver
smooth and more even noise picture that enhanced readability and saved
video signal transmission traffic

Installation Pro cedure
Step 1: Securing camera
Place mounting plate at position which the camera will be
installed. Then fix the screw holder and then 4 ￠4*26mm
screws
Step 2: Cable arrangement
The whole instal l ati o n and connection process
should only be made by qualified service person or system installers
It is necessary to make sure that the cable hole has been protected with
waterproof installation process when the cable is connected from the side
Step 2: Adjust 3 Axes bracket while checking view angle from monitor
Loosen the X-Y-R screws and then adjust the 3 Axis bracket (X-Y-R Axis) to
get the viewing angle
-5 -
Three axes mechanical design allows 90° side views for wall mount and
furthest angle for ceiling mount when guarding a hall way.
Horizontal angle adjustment – by turning the platform to adjust the horizontal
angle180 degrees:360 degrees
X-AXIS Adjustment
Y-AXIS Adjustment
R-AXIS Adjustment
-6 -
Vertical angle adjustment – by turning the platforms to adjust the vertical
angle: 90 degrees
Step 3: Focus adjustment
Focus adjustment should be done with zoom focus at the same time
The default setting for zoom position is WIDE
Take the hexangular driver to adjust the zoom ratio (counterclockwise
= from wide to tele)
Turn the zoom ring to set to the desired zoom
Take the hexangular driver to adjust the focus ratio (clockwise = from
near to far)
Turn the focus ring to set to the desir ed focus
Step 4: Auto iris level adjustment
With built in DC type auto-iris lens,
installer needs to adjust the DC level
especially for conditions described
below.
If the camera is facing a window
but is placed in a relatively dark
room
If the subject background is
extremely bright or dark
If the brightness of the picture
on the monitor is not correct

L (counterclockwise): To decrease the contrast
H (clockwise): To increase the contrast
Step 5: IR distance adjustment
Installer may use IR adjustment function according to installation conditions. It
is suggested that the view angle should be checked before setting up the IR
distance. Below is the view angle and IR distance t a bl e suggested

***Above chart is a reference for general conditions. For best result, please make adjustments according
to installation site condition.
How do I know how many times to push for the distance I need?
The blue IR LED indicator will be flashed once the IR adjustment button is
pushed, the differe nt fl as hi ng time stands for different distance selected
1 Time: IR distance 30 Meter
2 Time: IR distance 40 Meter
3 Time: IR distance 20 Meter
4 Time: IR distance 10 Meter
***When power on for 15 mins without any further adjustment, the IR

adjustment button will go into sleep mode. If a reactivate is needed,
please push and hold the IR adjustment button for 20sec.
Auto Iris
This camera is built in with auto iris lens, the s hutt er s pee d i s fixed to 1/60 sec.
for NTSC and 1/50 sec. for PAL.
Super AGC
When install the camera for low lux environment, AGC will increase the
camera sensitivity.
White Balance Adjusting
ATW mode—Advanced white balance
This mode limits color temperature from 2500°K-9500°K
Auto Back-light Compensation
This intelligent aut o BLC is a newly dev el oped di g i t al l ight level control system.
It is activated automatically by screen histogram (contrast) and 225 area
window weighting integration to control iris gain and white balance
simultaneous, so that the clear object with adequate light level can always be
optimized.
Central window weighted average backlight compensation
This method is suited for cases where the main subject is fixed within the
screen.
Histogram backlight compensation
This method is suited for c ases w here the mai n subject mov es abo ut w ithin the
screen.
The combination of two types backlight makes it easier to arrange
backlight compensation operation to match the imaging conditions and
installation location.
