IRIS AND FIELD OF DEPTH
When adjusting focus, an important aspect is depth of field,
actually the depth of focus. The term depth is used because
we can describe it as being deep or shallow. If the in-focus
area goes well into (long distance) the subject field is referred
to as being deep. If the background area is not in focus but the
subject field is in sharp focus, the field is referred to as being
shallow.
The depth of field will change depends on the focal length of
the lens, the iris of the lens and the shooting distance. And in
surveillance cameras, the lens iris has an effect on focusing.
As the diagram makes clear, the wider the lens iris opening
size, the shallower will be the depth of field.

TECH TIPS ON FOCUS
Why will correct focus set during the day going off at night?
That’s because focus has not been precisely set. Shooting with an auto-iris lens, the amount of light during
the day makes the lens iris opening stay small. This results in a deep depth of field. But as day turns to night,
the lens iris opens to get more light, the depth of field is reduced and the focus goes off. When using auto-
iris lens, the ND filter must be used to approximate nighttime light conditions so that the lens iris stays open
and depth of field is reduced before adjusting the focus.
Neutral Density (ND) Filter: A filter which reduces light coming through the camera lens without any effect
on the light’s color temperature.
Certis VFD 03-AD with Two Potentiometer control of auto-iris lens do not require an ND filter for adjusting
focus. To achieve perfect focus simply and easily, just turn LEVEL potentiometer counter clock wise, the
lens iris open and shallow depth of field is maintained. Now adjust focus and then set LEVEL potentiometer
as required to light conditions.

INSTALLATION OF CAMERAINSTALLATION OF CAMERA
Note
Do not touch any component like the PCB and the lens, as this will damage the camera.
Adjust the camera angle.
Camera angle can be adjusted for up to 180º(± 65º) for horizontal rotation, for up to 90º (± 70º) for
vertical rotation.
Switch on the power supply of 12 V DC after completing camera Connections. The power is supplied to
the camera, Connect the monitor to the Video Output terminal to permit a picture to be viewed on the
monitor.
Set the Shutter
Shutter Fixed switch-4 to ON if light flicker is annoying. Light flicker may interfere with the view under
fluorescent lamps in the area where power frequency is 50 Hz. In such cases, set the Shutter Fixed
switch to "ON" position, and the image free from flickering can be obtained.
Note
If the Shutter Fixed switch-4 is set to the ON position, sensitivity is reduced compared to operation in
the OFF position. When using the camera in a dark location, or where light flicker is not an annoyance,
set the switch to the OFF position.
Adjust the angle of view with the Zoom ring and adjust the focus with the Focus ring for the best
possible picture reproduction. After lens adjustment completion, tighten both the Zoom ring fixing
screw and the Focus ring fixing screw.
Note
Do not touch any component like the PCB and the lens, as this will damage the camera.
Note
Since the Iris control (for sensitivity adjustment) is factory-preset to an optimum position for general
use, avoid tampering with it in normal conditions. Turning the control unnecessarily could cause
reduced picture quality or equipment failure. When the Iris control needs to be readjusted to match a
specific subject, adjust LENS IRIS LEVEL potentiometer to an optimum level. After adjustment, place a
lens cap over the lens for several seconds and then release to check the lens for correct iris operation.
If the focus is adjusted for a subject under good lighting conditions, the subject may go out of focus
when conditions become dark. To avoid this, adjust the lens focus after setting total open of lens iris.
(For total open lens iris move iris LEVEL Control Potentiometer counter clock wise position till
end.).Please refer to TECH TIPS FOR FOCUS AND DEPTH OF FIELD.

This Certis operating control guide is only intended for use by installers who have an adequate working
knowledge of video system! This guide outlines the most important information about camera. It is,
however, vital that you should also refer to the full Application Guide of Certis.
Functionality Specifications: As of Certis Technologies update knowledge, Certis with 32X32 mm size have
layout with Lowest Power Consumption & all possible external control function from Sony SS-11X solution.
Professional types Certis have different software and hardware built on board, supplied with 8 DIP
switches mounted on the top board to set function as below;
Setting White Balance: With different on-off combinations of switches 1, 2 & 3, user can set ATW-
Auto Trace White Balance, Indoor WB (Approx.3200K.), Fluorescent Light WB (4200K.), Fixed WB
(Approx. 4700K.), Out Door WB (Approx.6300K.) and Push to Hold WB.
ATW Mode: Auto Trace White Balance Mode. ATW is a feedback system
that automatically aligns the white balance by detecting the R, G and B
before gamma correction processing on DSP. To set ATW Mode, turn off
switches 1, 2, 3.
ATW Mode:

Push Mode: Turn on switch 2 and turn off switches 1,3. During Push
Mode operation is performed at a faster operating speed than ATW
without an operation frame or other limitations. However, the
response time, operation frame and other factors cannot be selected.
Indoor Fixed Mode: Turn on switch 3 and turn off switches 1 and 2.
Color temperature will be set at approximately 3200K .
Fluorescent Light Fixed Mode: Turn on switches 1,3 and turn off
switch 2. Color temperature will be set at approximately 4200K .
Manufacturer Default Fixed Mode: Turn on switches 2,3 and turn off
switch 1.Color temperature will be set at approximately 4700K .

Hold Mode: Useful for locking white balance by using white reference
at available light conditions.
Step-1 First turn on switch 2, face camera towards white paper for 3
to 5 seconds, Step-2 turn on switch 1. After this two steps, operation
stops ATW and mode shifts to White Balance lock mode, and RED and
BLUE gain at that point written to the EEPROM of camera. To perform
the same White Balance after next power restoration, keep switches
1 & 2 at ON .
Shutter Fixed Mode: Turn on switch 4, the shutter speed will be fixed
at 1/100(s)- NTSC and 1/120(s)- PAL to reduce the flicker of
fluorescent lights. In fixed shutter mode, AE operation is performed
only by AGC control.
AGC Max/Min: Turn on switch 5 to set Minimum AGC gain,turn off
switch 5 to set Maximum AGC gain.
