2 Installation
Before you start:
Please make sure that the device in the package is in good condition
and all the assembly parts are included.
Make sure that all the related equipment is power-off during the
installation.
Check the specification of the products for the installation
environment.
Check whether the power supply is matched with your AC outlet
to avoid damage.
If the product does not function properly, please contact your
dealer or the nearest service center. Do not disassemble the
camera for repair or maintenance by yourself.
Please make sure the wall is strong enough to withstand three
times the weight of the camera.
For the cement ceiling, you need to mount the camera with
expansion screws. For the woodiness ceiling, you can mount the
camera with self-tapping screws.
The wall should be thick enough to support at least 4 times the
weight of camera and its components.
The ceiling mounting is applied to camera with 2.1mm lens; The
corner mounting is applied to camera with 2.8mm lens.

Appendix
1 Glossary
Note:
The glossary gives brief explanations to the basic operation principle
or the basic function of the camera. However, it doesn’t mean the
listed functions are all supported by the cameras mentioned in this
manual. Please take the function in the corresponding specification
as the standard.
Definition:
Definition is the degree to distinguish the edge between two parts
clearly.
Contrast:
Contrast is the color difference between the brightest and darkest
parts.
Saturation:
Saturation is the degree of color purity. The color is purer, the, the
image is brighter.
DAY/NIGHT Auto Switch:
The cameras deliver color images during the day. And as light
diminishes at night, the cameras switch to night mode and deliver
black and white images with high quality.
AGC:
720P IR Dome Camera·User Manual
34
34
AGC is a control circuit that automatically changes the gain of a
receiver or other piece of equipment, so that the desired output
signal remains essentially. When under low illumination, AGC will
regulate the gain and amplification of the video signal.
S/N ratio:
It is the ratio of Signal voltage and noise voltage. The ratio is larger,
the effect of noise is less, and the image is clearer.
White Balance:
White balance can remove the unrealistic color casts. White balance
is the white rendition function of the camera to adjust the color
temperature according to the environment automatically.
BLC:
If you focus on an object against strong backlight, the object will be
too dark to be seen clearly. The BLC (Backlight Compensation)
function can compensate light to the object in the front to make it
clear, but this causes the over-exposure of the background where the
light is strong.
SMART IR:
The SMART IR adopts the smart image processing technique to
automatically adjust the brightness curve by detecting multi-zone
brightness, and so as to prevent the over exposure of central point
existed in short IR distance conditions.
Motion Detection:
In the user-defined motion detection surveillance area, the moving
object can be detected and trigger alarm. The sensitive level can be
customized according to the environment.
720P IR Dome Camera·User Manual
35
35
Privacy Mask:
This function allows you to block or mask certain area of a scene,
thus prevent the personal privacy from recording or live viewing.
OSD (On Screen Display):
OSD is the texts superimposed on a screen. It can show the menu on
the screen.
Synchronous System:
Synchronization of the camera usually contains power
synchronization and internal synchronization. Internal
synchronization is realized by the synchronous signal which is
generated by the inside crystal oscillator.
ICR Auto Switch:
The filter will filter infrared light during the daytime and change to
normal filter at night to ensure a high sensitivity and clear image.
WDR (Wide Dynamic Range):
The wide dynamic range (WDR) function helps the camera provide
clear images even under back light circumstances. When there are
both very bright and very dark areas simultaneously in the field of
view, WDR balances the brightness level of the whole image and
provide clear images with details.
EIS (Electronic Image Stabilization):
Electronic image stabilization function can reduce certain ranges of
vibration which is caused by the external environment.
3D Digital Noise Reduction:
Comparing with the general 2D digital noise reduction, the 3D digital
noise reduction function processes the noise initiated by CCD besides
720P IR Dome Camera·User Manual
36
36
processing the noise in the separated Y video signal and C video
signal.
HLC (High Light Compensation):
The HLC is capable of detecting and reversing the bright spots in the
picture (such as headlights) to black so as to achieve optimum picture
quality.
Digital Zoom:
Digital zoom helps to crop the entire image, and then digitally enlarge
the size of a portion of image that is needed to zoom in on.

2 Troubleshooting
Problem 1:
Why does the camera restart intermittently? And the problem is
much more serious when infrared lights of IR camera are turned on at
night.
Possible Reasons:
The main and common reason is power supply shortage. This
problem may happen to the IR camera especially at night, because
the infrared lights are turned on at night and increase the power
consumption.
To Solve the Problem:
You need to ensure that the power supply matches with ±10% of the
nominal voltage. And the power consumption of power adapter
should meet the demand of the camera.
Problem 2:
The camera can never be focused by adjusting the focus-stick on the
lens. And there is also no use adjusting the back focus.
Possible Reasons:
The camera needs the lens with CS lens mount. When you install a
lens with C lens mount, the camera will never be focused.
To Solve the Problem:
You can change a lens with CS lens mount to the camera.
Or you can use a C/CS adapter ring between the camera and the lens
with C lens mount.

Problem 3:
The camera is installed with an auto-iris lens. You adjust the focus to
get a clear image in the daytime. But the image is defocused at night.
Possible Reasons:
In the daytime, the illumination is high, so the iris is adjusted to a
small size automatically. The DOF (depth of field) is long. But at night,
the iris is adjusted to a large size automatically, so the DOF is
shortened. The focus you adjusted in the daytime now locates out of
the DOF, so the image is defocused at night.
To Solve the Problem:
When you adjust the focus for a camera with an auto-iris lens, you
need to set the lens type to AES (auto electronic shutter) mode.
Under AES mode, the iris is adjusted to the largest size automatically.
Then you can adjust the focus to get a clear image. At last, you need
to set the lens type back to AI (auto iris) mode.
Or you can adjust the focus in low illumination condition, such as at
night.
Problem 4:
A camera with OSD menu and an auto-iris lens displays black video.
But the OSD menu can be called and displayed.
Possible Reasons:
Auto-iris lens connector is loose contact.
Or the iris driven mode of the camera does not match with the mode
of auto-iris lens.
To Solve the Problem:

Check the auto-iris lens connector to ensure good contact.
Set the iris driven mode of the camera the same as the mode of lens.
The modes can be VD (video drive) or DD (direct drive). DD mode is
commonly used.
