viii
Document Information
Warning:
1. The camera cover is an essential part of the product. Do not open or remove it.
2. Never operate the camera without the cover in place. Operating the camera
without the cover poses a risk of fire and shock hazards.
3. Do not disassemble the camera or remove screws. There are no user
serviceable parts inside the unit.
4. Only qualified trained personnel should service and repair this equipment.
5. Observe local codes and laws and ensure that installation and operation are in

Electrical Safety Notice and Warnings
Warning:
1. Read the installation instructions before you connect the unit to a power source.
2. Electrical safety should always be observed. All electrical connections must be
performed by a certified electrician.
3. Use the supplied power supply and protect against static electricity,
ground faults and power surges.
4. The unit uses a three-wire power cord to make sure that the product is properly
grounded when in use. If the intended power outlet does not support three
prongs, one of which is a ground, contact an electrician to install the appropriate
outlet. NEVER remove or otherwise attempt to bypass the ground pin of the
power cord. Do not operate the unit in the absence of a suitably installed ground
conductor.
5. If you use an extension cord with this system, make sure that the total ampere
rating on the products plugged into the extension cord does not exceed the
extension cord ampere rating.
6. To avoid possible shock hazards or damaging the unit, assure that the positive
and negative of the power leads are properly connected to the terminal block
connector before plugging it into the unit or turning on the power source.
7. In the following situations, the electric power should be turned off immediately
and appropriate repairs, replacements or remedies should be taken if:

The power line or plug is damaged, frayed or shows heavy wear.

The unit has been physically crushed or deformed.

The unit has been exposed to water.

The unit has been exposed to, or shows signs of damage from, fire,
intense heat, heavy smoke, fumes, or vapors.

Electrical connections of the unit become abnormally hot or generate
smoke.

The unit has been dropped, damaged or shows signs of loose internal
parts.

The unit does not operate properly.
ix
Quasar CF-4251 User and Installation Guide
Caution:
To avoid damage from overheating or unit failure, assure that there is sufficient
temperature regulation to support the unit’s requirements (cooling/heating). Operating
temperature should be kept in the range 0° to 50°C (32° to 122°F), with no more than
90% relative humidity (non-condensing).
Minimizing EMI and RFI
When wires run for a significant distance in an electromagnetic field, electromagnetic interference
(EMI) can occur. Strong EMI (e.g. lightning or radio transmitters) can destroy the units and can pose
an electrical hazard by conducting power through lines and into the system. Poor quality or worn
wiring can result in radio frequency interference (RFI). To minimize the effects of EMI and RFI,
consult your reseller.
Site Preparation
There are several requirements that should be properly addressed prior to installation at the site.
The following specifications are requirements for proper installation and operation of the unit:

Ambient Environment Conditions: Avoid positioning the unit near heaters or heating
system outputs. Avoid exposure to direct sunlight. Use proper maintenance to ensure that
the unit is free from dust, dirt, smoke, particles, chemicals, water or water condensation,
and exposure to EMI.

Accessibility: The location used should allow easy access to unit connections and cables.

Safety: Cables and electrical cords should be routed in a manner that prevents safety
hazards, such as from tripping, wire fraying, overheating, etc. Ensure that nothing rests on
the unit’s cables or power cords.

Ample Air Circulation: Leave enough space around the unit to allow free air circulation.

Cabling Considerations: Units should be placed in locations that are optimal for
the type of video cabling used between the unit and the cameras and external
devices. Using a cable longer than the manufacturer’s specifications for optimal
video signal may result in degradation of color and video parameters.

Physical Security: The unit provides threat detection for physical security systems. In order
to ensure that the unit cannot be disabled or tampered with, the system should be installed
with security measures regarding physical access by trusted and un-trusted parties.

Network Security: The unit transmits over IP to security personnel for video surveillance.
Proper network security measures should be in place to assure networks remain operating
and free from malicious interference. The unit is intended for installation on the backbone
of a trusted network.

Electrostatic Safeguards: The unit as well as other equipment connected to it (relay
outputs, alarm inputs, racks, carpeting, etc.) shall be properly grounded to prevent
electrostatic discharge.
The physical installation of the unit is the first phase of making the unit operational in a security
plan. The goal is to physically place the unit, connect it to other devices in the system, and to
establish network connectivity.

5.2 Power and Ethernet Cable Connection
Power Connection
Make sure the camera’s power cable is properly connected. Refer to Table 1: CF-4251 Camera
Connector Designations. If using Power over Ethernet (PoE), make sure Power Sourcing Equipment
(PSE) is available on the connected network. All electrical work must be performed in accordance
with local regulatory requirements.
Ethernet Cable Connection
A Cat 5 Ethernet cable is recommended for network connection. For best transmission quality, the
cable length should not exceed 100 meters (328 feet). Connect one end of the Ethernet cable to the
CF-4251 camera and the other end of the cable to the network switch or PC.
Note:
An Ethernet crossover cable can be used when connecting the CF-4251 camera
directly to the PC.
Check the status of the link indicator and activity indicator LEDs. If the LEDs are unlit, check the LAN
connection.

5.3 Lens Mounting
Before installing your camera, install the camera lens.
Note:
The camera lens is sold separately and should be selected to match the needs of the
scene and to optimize the use of the camera capabilities. See Mounting and Lens
Accessories.
Auto Iris vs. DC lens
A manual iris lens is best for use in scenes where illumination never changes, such as a persistently
lit store or office. Auto iris is better suited for scenes where the lighting may vary throughout the
day and night.
Note:
A smaller focal length number allows a wider field of view. A larger focal number
represents a narrower and deeper field of view.
The trade-off is in the amount of detail and depth of view vs. the width of view. For example a 2.8 or
4 mm lens might be sufficient for indoor warehouse and office and an 8mm might be better suited
for outdoor perimeters.
After you select your lenses and see the amount of detail provided consider your security
surveillance coverage, camera locations and any additional needs that may be discovered. Consult
your DVTEL rep if you have any questions.
To mount a lens on the CF-4251 camera
1. Remove the plastic insert covering the threaded camera lens-mount.
Tip:
Do not touch the sensor or allow dust to accumulate in the lens-mount.
2. If you are using a C-mount lens, screw a 5mm adapter ring into the C-Mount to
convert it to a CS-Mount (see Figures below).
C to CS Mount Adapter
Completion
3. Align the lens threads into the lens-mount and screw on the lens.

Installation
4. If your lens has a DC auto iris, plug the auto-iris cable from the motorized lens
assembly into the AUTO IRIS port of the camera.
Figure 5: Auto Iris Port Connection
Tip:
If there are problems focusing, it might be necessary to make a back focus adjustment.
5.4 Initial Camera Configuration
To perform the initial camera configuration:
1. Unpack the camera and remove the protective cover.
2. Remove the PE cloth sheet and lens cap. Attach the dome cover to the body.
3. Connect one end of the Cat 5 Ethernet cable to the Ethernet port of the camera and the
RJ45 connector at other end to the Power Sourcing Equipment (PSE) device, such as a
switch.

Using the DNA Utility to Search and Access the Camera
6 Using the DNA Utility to Search and Access the Camera
6.1 Introduction
The DVTEL Network Assistant (DNA) is a user-friendly utility that is designed to easily discover and
configure DVTEL edge devices on a network.
The DNA tool has a simple user interface and does not require any installation. The software is
provided as a single, standalone executable. It runs on any PC.
DNA provides a central location for listing all the DVTEL CM, CF and CP camera models accessible
over the network. Once listed, each camera can be right-clicked to access and change the network
settings.
If the network settings are changed for some reason, a new search will relist the units. The units may
then be configured via the web interface.
If DVTEL Latitude is being used, configure the unit with a static IP address rather than with DHCP.
This ensures that the IP address will not automatically change in the future and interfere with
configurations and communication.
The camera must be made accessible for the network’s addressing.
Note:
DNA is an enhanced software alternative to Device Search. Either of these programs
may be used.
To install DVTEL Web Player (DCViewer) software online:
Upon initial connection to the camera, a prompt to install the DVTEL Web Player (DCViewer)
appears. If the web browser does not allow DVTEL Web Player to install, check the Internet security
settings or ActiveX controls and plug-in settings to continue the process. See Internet Security
Settings.
Caution:
Users who have previously installed the DVTEL Web Player (DCViewer) on the PC
should delete the existing DCViewer from the PC before accessing the camera. For
information on how to uninstall and clear Temporary Internet Files, see Appendix
A5: Deleting the Existing DCViewer.
Follow the instructions below to start using the DNA application.
6.2 Quick Start
1. Install and run the DNA application on a computer connected to the network. The
software is an .exe file supplied in a zip file together with an Online Help file (.chm).
2. Extract both files from the zip file, and place them together in a new directory. Both files
should have the same name, but different extensions (.exe and .chm).
3. Upon launching the tool, DNA automatically discovers all devices on the network. The
initial launch creates a default .ini file (dna.ini).
4. In the event that there are devices that are not authenticated, click Login and enter login
credentials for the devices.

7.4.1.5 GOV Settings
You can set the GOV length to determine the frame structure (I-frames and P-frames) in a video
stream for saving bandwidth. The setting range is from 2 to 64. A longer GOV means decreasing the
frequency of I-frames. Click Save to confirm the GOV setting.
7.4.1.6 H.264 Profile
The H.264 standard defines 21 sets of capabilities. These are referred to as profiles and they target
specific classes of applications. In the security industry, the most common are as follows:

74
Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, Baseline
Profile is used in some videoconferencing and mobile applications. This is the most common
profile used in IP security cameras due to the low computational cost of processing the video
using this profile
Configuration and Operation

Main Profile (MP)
This profile provides improved picture quality at reduced bandwidths and storage costs and
is becoming more common as the camera processors (DSPs) become more able to handle
the processing load. Main Profile can save 10-30% over Baseline.

High Profile (HP)
High Profile is the primary profile for HD broadcast and Blu-ray HD disc media applications. It
can save 10-30% of the storage cost over Main Profile. However, it may also increase video
latency, depending on the stream structure. Quasar models default to the Main Profile to
provide the best trade-off between storage size and video latency.
Click Save to confirm the settings.
7.4.2 Video Compression
From the Video Compression page, you can specify MJPEG/H.264 compression settings.
Figure 74: Video Compression Screen
MJPEG Compression Setting
A higher value implies higher bit rates and higher visual quality. The default setting of the MJPEG Q
factor is 35. The setting range is from 1 to 70. Click Save to confirm the setting.
Note:
MJPEG is not supported by Latitude.
H.264-1/H.264-2 Compression Setting

Configuration and Operation
7.5.1 Exposure
The exposure is the amount of light received by the image sensor and is determined by the amount
of exposure by the sensor (shutter speed), and other exposure parameters.
Administrators may either allow the camera to automatically select an exposure level using a
programmed algorithm or choose the level themselves. Even in Auto Shutter, a Minimum Shutter
Speed may be set from the drop-down menu to ensure a maximum level of exposure. In Manual
Mode, the administrator can choose fixed shutter speeds from a drop-down menu. The smaller the
number (the higher the shutter speed) that the administrator selects, the lower the exposure level
and vice versa. Following is an illustration of the Camera menu.
Figure 80: Camera Settings Screen – Exposure
There are two exposure modes: Auto Mode and Manual Mode.
Auto Mode
There are three settings within Auto Mode:

Auto Iris Min Shutter Speed – When selecting this mode, the shutter is completely open and
the exposure priority is given to the iris. Shutter speed and AGC circuit function
automatically in cooperating with the iris to achieve a consistent exposure output.

Gain
A nominal video signal level is usually 1 volt peak-to-peak for composite video, 0.7 volts for
component or RGB video, or 0.3 volts for the chrominance subsection, at which level a fully
saturated picture is transmitted to the acceptor. However, for cases where the video signal is
attenuated, a low-noise, high-gain analog amplifier is built into quality video processing equipment.
This amplifier provides video gain control whereby the video signal can be boosted or reduced. Dark
pictures resulting from low level lighting are easily adjusted.
The Gain drop-down menu enables controlling the video gain from Off or in steps from 1 to 9.

7.5.2 White Balance
Shown below is the drop-down menu for controlling the camera’s White Balance (color balance).
Figure 81: Camera Settings Screen – White Balance
A camera needs to find a reference color temperature as a way of measuring the quality of a light
source for calculating all other colors. The unit for measuring this ratio is in Kelvin (K) degrees. You
can select one of the White Balance control modes according to the operating environment. The
table below shows the color temperature of some light sources for reference.
Light Sources
Color Temperature in K
Cloudy Sky
6,000 to 8,000

Candle Flame
1,200 to 1,500
Three White Balance modes are available:
84

Auto – The Auto Balance White mode computes the white balance value output using color
information from the entire screen. It is suitable for an environment with a light source color
temperature in the range of approximately 2,700 ~ 7,500K.

ATW (Auto Tracking White Balance) – The Auto Tracking White Balance function
automatically adjusts the white balance in a scene while temperature color is changing. The
ATW Mode is suitable for an environment with a light source color temperature in the range
of approximately 2500 ~ 10,000K.

Manual – In this mode, you can manually change the white balance value. You can select a
number between 0 – 127 for either/both Rgain and Bgain to increase the red and/or blue
luminance. Press <√> to confirm the new setting.
Configuration and Operation
7.5.3 Picture Adjustment

Configuration and Operation
7.5.6 IR Function
The IR Function setting activates the IR Cut (IRC) filter for electronic day/night operation. The
day/night IRC switching mechanism operates according to the ambient light level, rather than
activation of the IR LED mode. The drop-down menu enables you to select from Auto/On/Off/Smart
modes. The default mode is Smart.
Following is an explanation of the four settings:

Auto Mode – The camera converts from Day mode (color) to Night mode (monochrome)
automatically at nighttime or in low light conditions. When there is sufficient light, the
camera converts automatically from Night mode to Day mode.

On – Activates IR mode (puts camera into monochrome/Night mode).

Off – Deactivates IR mode (puts camera into color/Day mode).

Smart – Smart mode enhances monochrome/Night mode stability when IR illumination is
dominant and keeps the camera from switching between Day and Night modes. In this
mode, the IR Cut filter is on (i.e. monochrome/Night mode) when the IR LED illuminator also
is activated. This prevents the camera from returning to color/Day mode.
Press <√> to confirm the new setting.

7.5.7 WDR Function
The Wide Dynamic Range (WDR) function resolves high contrast or changing light issues in order to
enhance the video display. The WDR is adjustable from Low, Mid to Hi. A higher level of WDR
represents wider dynamic range, so that the IP camera can capture a greater scale of brightness.
Press <√> to confirm the new setting.
Figure 86: Camera Settings Screen – WDR Function
7.5.8 Noise Reduction
Different level options for 3D Noise Reduction (3DNR) include Low, Mid and High. A higher level of
3DNR generates relatively enhanced noise reduction.
The proprietary Smart Picture Quality (SPQ) video processing method can drastically minimize
motion blur and provides clear images even in low-light environment. The combination of SPQ and
3DNR at different levels further yields exceptional video performance in various conditions.
The Noise Reduction function reduces image noise/snow, enabling the IP camera to deliver clearer
images in low-light conditions. The Noise Reduction is adjustable from 3DNR Low, 3DNR Mid, 3DNR
Hi, SPQ, SPQ + 3DNR Low, SPQ + 3DNR Mid, to SPQ + 3DNR Hi. Press <√> to confirm the new setting.

cases, it is required to adjust back-focus only when the camera’s lens cannot hold focus throughout
its zoom range. If the focus cannot be achieved within the zoom range, you may need to adjust the
back-focus.
Requirements:
Tools required when carrying out back-focus adjustment include:
o
Back focus adjuster (in the IP camera’s package)
o
Test chart/contrasting object
To adjust back focus:
1. Set the Exposure Settings as follows:
a. In the Viewer, select the Camera tab.
b. From the Exposure menu, select Auto Shutter mode. See section 7.5.1, Exposure.
c. Click the
icon to save changes.
Tip:
It is preferable do the adjustment during low light conditions.
2. Do the following:
a. View an object at least 75 feet (23 meters) away. For greater telephoto capable lenses,
the object can be located further away. If the field of view is less than this distance, the
object should be as distant as possible.
b. Adjust the zoom to the extreme telephoto position.
c. Adjust the focus to the best possible focused image.
d. If the image is not focused (sharp), loosen the back-focus ring retaining screw with the
supplied hex tool and rotate the lens mount to adjust the back focus as needed to
achieve a sharp picture in focus.

f.

g. Tighten the back focus ring retaining screw to secure the ring in place.
h. Return the camera’s Exposure Setting to Auto Iris if this was temporarily changed to
Auto Shutter mode during focusing.
