* When adding 485-bus accessories, the 485-bus cable must be fitted with the ferrite clamp nearest the D4.
A quick overview of digital recording
Digital multiplex recorders work in exactly the same way as analogue
multiplexers except that they use hard disks and digital tape to store video,
instead of VCR tapes.
Analogue recording uses time-lapse recording to extend the length of time
recorded onto 2 or 3-hour tape - recording fewer pictures every second.
Adjusting the number of pictures recorded every second also extends the length
of time recorded onto the hard disk of a D4. However, other factors also
determine the amount of time that can be stored on the disk of a digital
multiplex recorder:
• The image quality
• The record rate
• The hard disk capacity
Image quality
Digital multiplex recorders store images in a compressed format, allowing images
to be recorded more efficiently. The higher the compression, the smaller the file
size, but the image quality will suffer. D4 can compress images between 6KB and
45KB.
Kilobytes and Gigabytes are units of storage:
1GB = 1024 Megabytes (MB)
1MB = 1024 Kilobytes (KB)
With analogue recording, the image quality is dependent on the type of VCR
being used; VHS or S-VHS. D4 allows the image quality to be altered by adjusting
the image size, for example, VHS quality is 14KB, S-VHS is 18KB, and greater than
S-VHS is 25KB*.
Using a larger image size will fill the hard disk faster than a smaller image size, as
more space is required to store it. To achieve the same amount of recording time
when a larger image size is used requires the record rate (PPS) to be reduced.
* Note that as for all digital recording, image quality can vary for different scene types, S-VHS quality may
be 18KB in one scene, but it may be 30KB or more to get the same quality in a scene with more detail.

Quick Install
Record rate
The record rate is the amount of pictures recorded to disk in a second, or pictures
per second (PPS). This is a system wide figure, so whether 1 or 4 cameras are
recorded, the record rate remains the same. The update rate per camera can be
worked out using the record rate:
Update rate = No. of cameras
Record rate
A table of common record rates can be found in Appendix 1.
Hard disk capacity
Analogue VCRs use 3-hour tapes which record a finite number of images. Unlike
a VCR, the number of images that can be recorded to a digital multiplex recorder
can be increased by using a larger capacity hard disk. At the time of writing, D4 is
available in 40 and 160GB hard disk sizes.
Using a larger hard disk will allow image quality, recording rate, or recording time
to be increased. For example, a 40GB disk can record for 8 days at the default
settings (24-hour time-lapse mode at S-VHS quality).
Calculating recording time
D4 calculates the recording time automatically when the record rate and image
quality are entered. Alternatively, an interactive record calculator is available for
download from our web site:
www.dedicatedmicros.com
D4 can be installed in as little as 4 steps, and being plug-and-play, cameras will be
detected and recorded automatically.
STEP 1. Connect cameras
Connect cameras to the video inputs marked VID1 to VID4. Use the bottom row
of connectors for looping through to other equipment.
STEP 2. Connect monitors
Connect the video output marked MON A to the Main monitor (digital playback
and multiscreens).
Connect the video output marked MON B to the optional Spot monitor (analogue
full-screen images).
STEP 3. Connect the external devices
If external devices need to be connected to D4, go to the next section ‘Connecting external devices’, before proceeding to Step 4.
STEP 4. Connect power
Once the D4 is in its final position and all external devices have been fitted and
powered, connect the PSU to the rear of the unit and apply the power. The power-up
procedure may take up to one minute before D4 can be used.

Connecting External Devices
D4 uses 485-Bus networking to interconnect Dedicated Micros products and
accessories. Storage devices can be connected to the SCSI port.
Devices that can be connected to D4 include:
Storage devices
Alarms and relays
Audio devices
Ethernet networks
Dial-up modems
If you do not require any of the above devices to be connected to D4, move on to
‘Configuring D4’ - Page 9.
Connecting storage devices
Images are recorded to the internal hard disk for instant playback and searching
by the operator. The capacity of the internal disk affects the amount of images
and time that can be recorded. For example, a D4 with a 40GB hard disk can
record for 8 days at a 24-hour time-lapse mode using a 160GB hard disk allows
one month of recording.
The internal hard disk is a temporary storage device as the images are constantly
being overwritten after a certain period of time. If images need to be kept for
longer then external storage is required. The 50-way high density SCSI-2 port on
the rear of the D4 is used to connect to external storage.
Images can be copied from the internal hard disk onto CDR disks for long term
storage. CD’s are ideal for recording relatively small amounts of images such as
events, video clips, or incidents. These images can be played back on any PC with
a CD drive and DM Playback software installed.
The table below shows the recording times at typical recording rates (at S-VHS
image quality, 18KB):
Connecting Alarms and Relays
Dry contact alarms can be wired directly to the alarm connection on the back on
the D4. There are 5 alarm inputs, one for each camera, and a global alarm input.
The alarm connections are as follows:
The polarity of the alarms - normally open or
normally closed, can be set in the ‘Camera
setup’ menu.
The global alarm input is used to set or unset the schedule function.
An alarm trigger performs the following actions:

Relay connections are as follows:
Important Note: The onboard relays are rated at 24V 500mA, do not attempt to
connect mains power through the relays.
Connecting Audio devices
D4 can record and playback a single stream of audio linked to camera 1. There
are two audio input ports: MIC IN and LINE IN, and an audio output: LINE OUT.
Connecting a microphone to MIC IN.
Connect the microphone into the 3.5mm jack plug labelled MIC IN. It is important
to select the correct type of microphone for connection to the D4. D4 requires an
electret microphone with a sensitivity of –50dBV or better.
Connecting a pre-amplifier to LINE IN.
Where additional microphone gain and/or adjustable gain is required, an external
microphone pre-amplifier with adjustable gain is recommended. A microphone
pre-amplifier will provide a line level 1V pk-pk signal that can be connected to the
RCA socket labelled LINE IN on the D4.
The line level input has the following specification:
Line IN 47kΩ input impedance, 1V pk-pk
Pin Connection Action
1-2 Relay 1 Close on Alarm
3-4 Relay 2 Close on Activity Detection
5-6 Relay 3 Close on Camera fail
7-8 Relay 4 Undefined
Connecting the LINE OUT to an amplifier.
Connected the RCA socket labelled LINE OUT to an external amplifier or powered
loudspeakers.
The line level output has the following specification:
Line OUT 1V pk-pk
Recording audio
Once the microphone or pre-amplifier is connected to the D4, the option to
record audio should be enabled in the menu. See page 17 for details of enabling
audio recording.
It is advised that you test the quality of audio playback, it may be necessary to
increase the gain of the microphone
As the audio is linked to camera 1, it is required that camera 1 be viewed, either
in a full screen or in a quad view during playback to hear the audio.
Connecting to an Ethernet network
D4 can be connected to a standard 10-baseT Ethernet network allowing full
control of the D4 from a remote location.
Network connection
To connect a D4 to a network you will need the following items:
• A spare 10-baseT network point.
• A RJ-45 network cable (CAT5 or equivalent).
• A static IP address and Subnet mask (some networks may also require a
Default gateway, consult the network administrator for advice).

Standard and Event PPS
Select a record rate in pictures per second (PPS) to be recorded across all cameras.
When a single camera is being recorded. The maximum record rate is 25PPS for
PAL and 30PPS for NTSC cameras when a single camera is recorded. When
multiple cameras are recorded the maximum record rate is 18PPS.
The default record rate is 3PPS, this is the equivalent to a VCR in 48-hour timelapse mode. However, because there are only a maximum of 4 cameras the
update rate is faster than a 24-hour time-lapse mode recording 9 or 14 cameras.
To configure D4 to record only events, select the Standard PPS as 0PPS and the
Event PPS to a value you want the events to record at for example, 3PPS. The D4
will then not record any cameras until activity or alarms are triggered, it will then
record the alarmed/activity camera interleaved with the other cameras.
Note: Audio is not recorded when the record rate is at 0PPS.
The table below shows the equivalent record rates of typical VCR time-lapse modes:
Figures in brackets are for NTSC systems.
14
You can decrease the update rate by increasing the record rate (PPS), the only
drawback is that the recording time will also decrease.
Events active
Select whether the alarms and activity are on or off for day, night, and weekend
schedules.
When an event is triggered it is automatically interleaved with the non-event
cameras, i.e. if camera 1 has an event, the recording sequence would be
121314121314 rather than the standard sequence of 12341234, effectively
increasing the record speed of camera 1.
Tip: By using event interleave, it is possible to keep the record rate constant but
effectively increase the speed of alarm or activity recording.
Recorded file size
The file or image size affects the quality of the images recorded to disk. A larger
file size has superior picture quality, but will fill the hard disk faster, so less time
will be recorded before the images will be overwritten.
The file size can be set between 6 and 45KB. The table below shows the image
quality at typical file sizes:
Note: The equivalent image quality is representative in most circumstances,
however, camera views with large amounts of image detail may require the file
size to be increased to obtain a similar image quality.
Increasing the file size over 40KB will decrease the maximum record rate to
18PPS, even if a record rate of greater than 18PPS is selected.
Maximum recording time
The maximum recording time is the number of days and hours before the images
are overwritten. The maximum record time is calculated automatically when
the standard or event record rate is highlighted and changed. Note that the
maximum recording time will include the audio, if it is enabled in the System
Options menu page.
Tip: Reducing the file size (KB) or record rate (PPS) can increase the maximum
recording time.
Total video storage
The figure displayed shows the total amount of internal and external disk capacity
available for video storage in GB (Gigabytes).
Earliest recording
The earliest recording displays the date and time of the first image on the disk.
Note: If an event partition is set (in the Event Setup menu) then the earliest
recording could be an event that is older than the first standard recording.

Event Setup
Auto event copy
Activity detection or alarm events can be automatically copied onto an external
Jaz® disk for reviewing at a later date.
Note: Iomega Jaz® disks may not be available in SCSI format in all countries.
Buzzer
The internal buzzer can be programmed to activate when an alarm, activity
detection, or a camera fail is detected. By default, the buzzer is deactivated.
Note: The camera fail buzzer will continue to activate until the failed camera is
reconnected or replaced. To deactivate the camera fail buzzer on the failed
camera, press and hold the corresponding camera key to enter the Camera Setup
menu and disconnect the camera video input.
Event partition
An event partition can be configured to protect events for longer than using just
the normal recording partition. When an event partition is configured, all events
will be saved to this area. The events are overwritten in a first in last out basis
when the partition is full.
To work out the required event partition size, use the following equation:
Where;
Days = Number of days to record before events are overwritten.
Image size (KB) = The recorded image size in kilobytes.
% Events = The percentage of recordings which are events.
Event PPS = The record rate of event recording (PPS).
For example, If you want to keep events for 5 days before they are overwritten,
alarms are triggered for 25% of the time, image size is 18KB, and the Event PPS
is 6 pictures per second the equation would be:
CAUTION: Specifying an event partition will reduce the disk space and hence
recording time for normal recording.

This option is used to configure the unit for connection to an Ethernet network or
dial-up. A pop-up box for configuring the network settings is displayed with the
following items:
System name
Each D4 on the network can be given a system name to help identification, the
unit name is displayed in the Network Viewing software. A maximum of 30
characters can be used for the system name. The default unit name is ‘D4’.
Tip: If you do not want the unit to automatically identify itself on a network, use
a ‘#’ symbol as the first character. You will still able to access the unit across the
network by typing in the IP address directly into the Network Viewing software.
Network
This option is used to enable or disable the network option. The network is
enabled by default.
ENGLISH
17
Bandwidth limit
The bandwidth used by the D4 can be limited to prevent overloading on slower
networks. The D4 has a 10MB/s connection (10Base-T).
The maximum bandwidth that a D4 will use (5 users viewing images) is 6Mb/s so
any limiting over 60% does not affect the bandwidth used by the D4. The
maximum bandwidth used by one user is approximately 2.5Mb/s
If you want to limit the bandwidth used by the D4 to 1Mb/s set the bandwidth
limit to 10%.
Note: Restricting the bandwidth does not decrease the image quality, but the
update rate of the images over the network will decrease.
IP address, Subnet mask, Default gateway
A unique IP address and a subnet mask must be given to the D4 in order to
communicate with it over a network. On an existing network these are often
obtained from the network administrator. A Default gateway will be required if
the D4 is going to be viewed from a remote location, such as a WAN or dial-up
via a router.
Note: The D4 requires a Static IP address, even if it is connected to a dynamic
(DHCP) network.
PPP address
The PPP (Point to Point Protocol) address is used when a Hayes compatible modem
is connected to the D4. The PPP address must be entered into the Network Viewing
software or Web browser to view images when connected to the D4.
By default, the PPP address is 172.017.002.002 when the TCP/IP address is at its
default setting of 000.000.000.000. The PPP address cannot be changed directly,
but is changed automatically when the TCP/IP address is adjusted.
Audio recording
A single channel of audio can be recorded on the D4, use this menu to enable or
disable audio recording. Audio recording takes up a small amount of storage,
approximately 4KB/s, this is regardless of the record rate (PPS) of the video. When
audio is enabled the record time is affected, check the new record time in the
‘Record Schedule’ menu.
Note: The audio recording is linked to Camera input 1, i.e. audio is only recorded
when camera 1 is recording. Camera 1 must be displayed to play back audio.
IR Receiver
The Infrared remote control option can be enabled or disabled from this menu.
The remote control mimics the front panel control of the D4. The remote control
does not allow the configuration of the menus.
When the IR receiver is enabled the IR LED on the D4 is solid green, when it is
disabled the IR LED switches to solid amber. The LED flashing green signifies an
IR signal being received.
Please refer to Appendix 2 for details of using the remote control.
Timed expiry
The timed expiry option allows images to be only held for a selected number of
days or hours. Images on the disk which are older than this time are not accessed.
By default there is no timed expiry.
Factory default
Use this option to return all settings to the factory condition.

Généralités sur l’enregistrement numérique
Un enregistreur multiplex numérique fonctionne exactement de la même manière
qu’un multiplexeur analogique, mis à part que les informations vidéo sont
stockées sur des disques durs et des cartouches numériques et non pas sur des
cassettes vidéo.
L’enregistrement analogique utilise le mode “Time-lapse” afin d’étendre la durée
enregistrable sur une cassette de 2 ou 3 heures (c’est-à-dire qu’il emmagasine
moins d’images à la seconde).
Cette méthode permet également d’accroître la durée enregistrée sur le disque
dur du D4. Cependant, avec un enregistreur multiplex numérique, il existe
d’autres facteurs qui influent sur cette durée :
• La qualité des images
• La vitesse d’enregistrement
• La capacité du disque dur
Qualité d’image
Un enregistreur multiplex numérique stocke les images sous une forme compressée,
permettant ainsi d’améliorer l’efficacité de l’enregistrement. Plus la compression est
importante, plus la taille du fichier est réduite, mais la qualité de l’image est évidemment
moindre. Avec le D4, la compression des images peut varier entre 6 et 45 ko.
Les capacités de stockage sont exprimées en kilooctets et en Gigaoctets :
1 Go = 1024 Megaoctets (Mo)
1 Mo = 1024 kilooctets (ko)
Avec l’enregistrement analogique, la qualité de l’image dépend du type de cassette
vidéo utilisé, VHS ou S-VHS. Avec le D4, la qualité varie selon la taille d’image
sélectionnée. A titre d’exemple, la qualité VHS correspond à un fichier de 14 ko,
le S-VHS à un fichier de 18 ko et pour une qualité supérieure au S-VHS, la taille
du fichier est de 25 ko*.
Le fait d’utiliser une taille de fichier image plus importante a pour conséquence de
remplir le disque dur plus rapidement, étant donné que chaque image occupe plus
d’espace. Pour pouvoir, dans ce cas, conserver la même durée d’enregistrement,
il est nécessaire de réduire la vitesse d’enregistrement (ips).
* Il est à noter que pour tout enregistrement numérique, la qualité d’image peut varier selon les différents
types de scènes. Ainsi, la qualité S-VHS peut correspondre à une fichier de 18 ko pour une scène et à un
fichier de plus de 30 ko pour la même qualité concernant une autre scène avec plus de détails.

Installation rapide
Vitesse d’enregistrement
Cette vitesse correspond au nombre d’images enregistrées sur le disque en une
seconde (unité de valeur en images par seconde / ips). Il s’agit d’un paramètre système
qui reste le même, quel que soit le nombre de caméras (de 1 à 4) prévu pour
l’enregistrement. En revanche, le taux de rafraîchissement propre à chaque caméra
varie selon la vitesse d’enregistrement et conformément à la formule suivante :
Taux de rafraîchissement = Nombre de caméras
Vitesse d’enregistrement
Un tableau regroupant les vitesses d’enregistrements communes est fourni en
annexe 1.
Capacité du disque dur
Les magnétoscopes analogiques utilisent des cassettes 3 heures qui autorisent
l’enregistrement d’un nombre limité d’images. Avec un enregistreur numérique
multiplex, cette quantité d’images peut être augmentée grâce à l’utilisation d’un
disque dur de plus grande capacité. A l’heure actuelle, le D4 est disponible avec
des disques durs de 40 et 160 Go.
L’augmentation de la capacité du disque dur permet d’accroître aussi bien la
qualité des images que la vitesse d’enregistrement et la durée de ce dernier.
Par exemple, un disque de 40 Go permet d’enregistrer jusqu’à 8 jours avec les
paramètres par défaut (mode “Time-lapse” 24 heures en qualité S-VHS).
Calcul de la durée d’enregistrement
Le D4 effectue automatiquement le calcul de la durée d’enregistrement dès
que les données relatives à la vitesse et à la qualité d’image sont saisies.
Alternativement, il est possible de télécharger un utilitaire de calcul interactif
à partir de notre site Internet :
www.dedicatedmicros.com
Le D4 peut être installé en 4 étapes. Etant donné qu’il s’agit d’un équipement “plug
and play”, il est prêt à fonctionner dès que le raccordement est terminé : les caméras
sont détectées et leurs images peuvent être enregistrées automatiquement.
ETAPE 1. Connexion des caméras
Raccorder les caméras sur les entrées vidéo repérées VID1 à VID4. Utiliser la
rangée inférieure de connecteurs pour établir une liaison en boucle vers d’autres
équipements.
ETAPE 2. Connexion des moniteurs
Raccorder la sortie vidéo repérée MON A sur le moniteur principal (pour la lecture
numérique et la visualisation multi-écrans).
Raccorder la sortie vidéo repérée MON B sur le moniteur d’observation optionnel
(visualisation d’images analogiques en mode plein écran).
ETAPE 3. Raccordement de dispositifs externes
S’il est nécessaire de connecter des dispositifs externes au D4, se reporter au
paragraphe “Raccordement de dispositifs externes” se trouvant à la page suivante
avant de passer à l’étape 4.
ETAPE 4. Connexion de l’alimentation secteur
Une fois le D4 installé sur son emplacement définitif et tous les appareils externes
raccordés et mis sous tension, connecter le bloc d’alimentation à l’arrière de l’appareil
et mettre celui-ci en marche. La procédure de mise sous tension peut prendre jusqu’à
une minute avant que le D4 puisse être utilisé.

Le D4 utilise un mode de mise en réseau par bus 485 pour interconnecter les produits
et accessoires Dedicated Micros. Des dispositifs de stockage peuvent être connectés au
port SCSI.
Les dispositifs pouvant être associés au D4 sont entre autres :
Dispositifs de stockage
Alarmes et relais
Dispositifs audio
Réseaux Ethernet
Modems à transmission téléphonique
Si aucun de ces dispositifs ne doit être connecté au D4, se reporter directement
au paragraphe “Configuration du D4”, page 9.
Connexion de dispositifs de stockage
Les images sont enregistrées directement sur le disque dur interne, permettant
à l’opérateur d’effectuer une lecture ou une recherche instantanée. La capacité
du disque détermine la quantité d’images enregistrables et, par conséquent,
la durée d’enregistrement possible. Par exemple, un D4 équipé d’un disque dur
de 40 Go peut enregistrer pendant 8 jours au mode “Time-lapse” 24 heures.
De même, un D4 pourvu d’un disque dur de 160 Go peut enregistrer pendant
un mois à ce même mode.
Le disque dur interne constitue un dispositif de stockage temporaire puisque les
images enregistrées sont, après une certaine période, remplacées par de nouvelles.
Si certaines images nécessitent d’être conservées plus longtemps, il faut avoir
recours à un dispositif de stockage externe. Celui-ci doit être connecté au port
SCSI-2 haute densité avec connecteur 50 broches situé à l’arrière du D4.
Pour un stockage de longue durée, les images doivent être copiées sur des CDR. Les
CD représentent en effet un support idéal pour l’enregistrement de petites quantités
d’images telles que des événements, des clips vidéo ou des incidents. Les images
ainsi copiées sur CD peuvent alors être lues à partir de n’importe quel ordinateur
équipé d’un lecteur de CD et sur lequel le logiciel de visualisation DM a été installé.
Le tableau ci-dessous présente les durées d’enregistrements sur CD aux vitesses
d’enregistrements types (qualité d’images de type S-VHS, 18 ko) :
Connexion d’alarmes et de relais
Les contacts secs d’alarmes peuvent être raccordés directement sur les entrées
d’alarme se trouvant sur le panneau arrière du D4. Cinq entrées d’alarme sont
disponibles (une pour chaque caméra plus une pour les alarmes générales).
Les broches de raccordement se présentent comme suit :
La polarité des alarmes (normalement ouverte ou normalement fermée) peut être
paramétrée via le menu "Paramétrage caméra".
L’entrée “Alarme générale” permet d’activer ou de désactiver la fonction
“Programmation horaire”. Le déclenchement d’une alarme peut provoquer
l’exécution des actions suivantes :

de toutes les caméras sont copiées sur le même CD.
