Visit www.dallmeier.com for possible updates.
Note (USA)
This equipment has been tested and found to comply with the limits for a Class A digital device, pur-
suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protecon against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instrucon manual, may cause harmful interference to radio communicaons. Operaon of
this equipment in a residenal area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense.
Appropriate Use
The DF4920HD-DN is a 5-megapixel HD network camera built into a compact and
lightweight box housing. Equipped with a tripod socket (1/4"-20 UNC) located on
the top and boom side, the camera ts all standard brackets with UNC threaded
screws. The camera is designed for indoor installaons on ceiling/wall brackets and
can be powered via PoE (Power over Ethernet, Class 0, IEEE 802.3af) or supplied
with 12 V DC (separate power supply unit required).

DF4920HD-DN Commissioning
NOTICE
The DF4920HD-DN is designed for indoor installaons.
For an outdoor use, the camera must be installed in a
proper weather-proof housing.
However, note that direct sunlight can cause extremely
high temperatures inside the housing.
In this case, it is absolutely necessary to use a ven-
lated, temperature-controlled weather-proof metal
housing and a sunshield, where required.
In addion, a metal slide should be used if the camera
is installed in a (weather-proof) housing to ensure
opmal heat dissipaon.

6 Requirements
General
Unfavourable local condions may shorten the lifeme of the product and may
cause malfuncons or damages.
Do not install/operate the device in places
• with a large amount of dust and dirt,
• with steam or oil vapours (e.g. kitchen),
• with direct sunlight,
• with strong heat emissions (e.g. radiator),
• with improper ambient temperatures,
• near sources with strong radiaon (e.g. radio transmiers, magnec elds),
• with corrosive surroundings (e.g. gases, salt water),
• with insucient air venlaon (e.g. closed cabinet).
Operaon
Observe the following notes for the operaon of the device:
• The device can be powered via PoE (Power over Ethernet, Class 0, IEEE 802.3af)
or supplied with a separate 12 V DC power supply unit.
However, always beware not to use both power sources simultaneously.
• Always ensure the correct polarity when using a separate 12 V DC power supply
unit.

14 www.dallmeier.com
DF4920HD-DN Commissioning
• Always disconnect the separate 12 V DC power supply unit from the mains
socket (pull out the power plug) before connecng or disconnecng the device.
• In order to comply with UL’s requirements, always use a UL-cered, Limited
Power Source (LPS) Class 2 power supply unit when operang the device with a
separate 12 V DC power supply unit.
• When using a separate 12 V DC power supply unit, interference caused by a
ground loop may occur in the analog video preview signal. In this case, use a
video signal transformer (balun) for galvanic (ground) isolaon between the
signal source (camera) and the RG-59 cable.
• If the device or the cables connected to the device are located near sources
with strong radiaon, the video image may be distorted.
• The device is equipped with automac gain control (AGC). In low light condi-
ons the image may be altered (e.g. noise). However, this is not a camera
malfuncon.
• The quality of the video image depends on the lens, the lighng condions and
the used monitor.
• The accuracy of the automac white balance (AWB) algorithm depends on the
used lighng. Mixed light (consisng of arcial light and daylight) may cause
color distorons (inaccurate color reproducon).
• Poor lighng can lead to an incorrect white balance.
Lens Specicaons
The camera is designed for use with CS-mount lenses.
If using a C-mount lens, you have to screw a C-/CS-mount adapter ring between
the lens and the camera.

7 Maintenance
The device may only be opened by qualied personnel for commissioning, inspec-
on, maintenance and repair.
Cleaning
If it is necessary to clean the device, observe the following notes:
NOTICE
Damage to the surface of the device
➡Clean the housing (outside) with a so, dry and
anstac cloth.
• Do not use detergents.
Damage to the image sensor
➡Only use approved methods and products for
sensor cleaning. For more informaon, contact the
Dallmeier Support.
• Always beware not to touch the image sensor
or sensor glass in order to avoid damages due
to scratching or loss of image quality due to
ngerprints.

16 www.dallmeier.com
DF4920HD-DN Commissioning
8 Aaching/Changing the Lens
To aach or change the lens, proceed as follows:
➡First, ensure a clean and nearly dust-free environment.
➡Hold the camera with the image sensor area facing downward so that no dust
will get into the camera or onto the image sensor.
➡During the following steps, always beware not to touch the image sensor
(sensor glass), other glass elements inside the camera or the rear lens element
in order to avoid damages due to scratching or loss of image quality due to
ngerprints.
➡Remove the camera body cap or carefully unscrew an already aached lens
from the camera in a counter-clockwise direcon (rst unplug the DC auto iris
4-pin connector).
➡Remove the rear lens cap of the new lens.
➡If necessary, remove dust from the image sensor (sensor glass), other glass
elements inside the camera or the rear lens element of the new lens using a
suitable bulb blower.
• However, beware not to disperse dust parcles inside the camera.
• Do not use canned air.
• Do not use organic solvents (alcohol, benzine) or coon buds for cleaning.
➡Carefully screw the new lens into the CS lens mount of the camera in a clock-
wise direcon and ghten it without using excessive force.
• Ensure that the lens thread does not get stuck and the lens is not ghtened
too rmly to avoid damages to the thread.

www.dallmeier.com 17
Commissioning DF4920HD-DN
➡If using a DC auto iris lens, connect the lens cable to the DC auto iris interface.
By default, the camera is congured for the use with DC auto iris lenses.
If using a lens with manual iris control, you have to recongure the camera accord-
ingly (more informaon can be found in the documentaon on camera congura-
on). Video signal-controlled lenses are not supported.
