 CCTV
cameras can be connected to a PC using any kind of video capture card. All
you need to do is connect the video output from the camera or RadioEye®
receiver to the input of the capture card to view the images from the camera
on the monitor. However a normal video capture card will not do much more
than this. If you want to upload images from more than one camera at the
same time, and view a smooth stream of images with a high number of frames
per second, record days and days of filming onto PC, or connect from a
remote PC, you need a product which has been specifically developed for
video surveillance. Like the D-Vision system.
D-Vision capture cards
The D-Vision PC-based video surveillance system comprises one or more cards
which are inserted into the PCI slot of the computer. You can use a desktop
PC or PC in industrial housing for rack-mounting, but not a laptop, as these
do not have a PCI slot.
There are two families of D-Vision capture cards:
 D-Vision
XP : capture rate : max 12.5 frames/second
per channel. Suitable for most video surveillance needs with excellent value
for money
D-Vision
RT : capture rate : max 25 frames/second per channel. Suitable
for high end applications, guaranteeing you will not lose a single frame,
and delivering smooth, television quality viewing

customer service.
DSE D-Vision
software
The D-Vision software package is a software for
Windows 2000/XP/VISTA which controls all the functions of the D-Vision
cards. Once installed it detects all the cards installed on the PC, displays
images from the cameras and enables you to manage all the recording and
surveillance functions.
Despite the high number of functions and options it offers, the graphic
interface is user-friendly: it can be used right away without specific
training. The updated graphics resemble a video recorder and are intuitive
and attractive right from the start. D-Vision software comes in two
versions:
 D-Vision
XP for capture cards DV-XP4 and DV-XP8+TV
D-Vision
RT for capture cards DV-RT4 and DV-RT8
Compression
Compression is the most important characteristic of D-Vision. The cards
utilize the exclusive VGZ proprietary compression algorithm, now further
optimized compared to the previous version (VGX). This is the only
compression algorithm specifically designed for surveillance purposes and
long-term recording. It offers the best compromise currently possible
between image quality, space occupied on the hard disk and video
transmission efficiency, delivering results which are not possible with
generic compression protocols such as MJpeg, Wavelet etc.
VGZ recordings, the length of which can be programmed, can be viewed using
the DV-Player and exported in AVI format.
DV-RT4 and DV-RT8 Real Time cards also includes a powerful hardware
compression chip H.264 (MPEG Part 10), the very latest development in
digital video compression, which offers high performance image capture
without overloading the CPU of the PC.
Super-resolution 704x576
Thanks to its exclusive compression algorithm and the use of the most
advanced acquisition chips, D-Vision records and displays images an at
unbeatable resolution of 704x576, delivering clear, sharp, full-screen
images.
Now you can forget the stamp-sized windows offered by generic compression
systems and traditional capture chips, which make you miss the days of
cassettes video recorders.
High capture speed
Thanks to its powerful processors, D-Vision cuts through all the old
barriers in terms of image fluidity. Installed on the fast PCs now
available, D-Vision finally delivers a high resolution (full screen) smooth,
continuous flow of images, instead of an irritating series of jerky frames.
The capture engines in the XP series allows up to 12.5 frames/second per
camera when recording 16 cameras simultaneously. This smooth jerk-free video
is suitable for most surveillance applications.
D-VisionRT cards, thanks to the powerful H.264 compression chip,
capture 25 frames/second, Real Time performance at the speed of television
images.
Full Triplex
The system does not stop recording during playback of previous recordings or
during access from a remote PC. There are no security lapses in any usage
mode.
Transmitting images via LAN, Modem,
Internet
D-Vision offers remote access via LAN, meaning
you can set up an unlimited number of control and recording stations using a
company TCP/IP network. You can also access the system from a remote PC
using the internet or a simple modem-modem call. You can view images from
all the cameras remotely, operate the controls (I/O) and even control Speed
Dome Cameras.
D-Vision has superb networking capacities. You can run very large systems
featuring numerous PCs and hundreds of cameras, all connected in real time.
You can also save your favorite layouts displaying cameras from different
PCs and different sites on the same screen.
Video and Audio synchronized locally and remotely
DVision XP records audio in the same VGZ file as the video,
automatically synchronized.
To hear the audio from a camera all you need to do is click on it, whether
in local or using a remote connection.
False-alarm free motion detection
D-Vision is able to signal intrusions in monitored areas by
monitoring changes in the pixels comprising the image. The D-Vision motion
detection system has evolved over time, and now offers numerous different
settings which make it a highly sensitive device virtually false alarm
proof. When an intrusion occurs the system can be set to start recording,
take photographs, play sounds on the PC, activate the outputs of the VG-IO
card, make telephone calls, connect up to remote PCs and even send emails
with photos and films attached.
VG-IO – Internal module 4 inputs + 4
relay outputs
The D-Vision software can also be used to control inputs and relay
outputs which can be used to interface with external electrical devices.
For example, the relay outputs can be used to activate a  siren,
turn on a light or open/close a door. These functions can be activated
following an intrusion or manually from local software or from a remote PC.
The inputs can be used to connect the alarm output from a burglar
alarm, for instance, or an infrared sensor, or a contact on a door, in order
to activate recording.
The VG-IO card has 4 inputs and 4 relay outputs and connects directly to the
D-Vision card by a flat cable. Each DV-XP4, DV-XP8+TV or DV-RT4 card accepts
a VG-IO card. Only the DV-RT8 card can take 2.
PT-811 + PT-908 – External module 8 inputs + 8 relay outputs on serial cable
RS485
 Module
PT811 has 8 inputs and 8 Open Collector outputs which can be entirely
controlled with D-Vision software. Unlike the internal VG-IO module, the
PT-811 module connects to the COM port of the PC with a twisted pair cable.
You will need to convert the serial port of the PC (RS232) into an RS485
connection using converter SD-232485 which can be ordered separately (see
below).
You can install up to 32 PT-811 modules on the same RS485 line, setting up a
different address using the configuration software. The RS485 BUS allows
wiring PT-811 modules up to 1200 m. far from the PC.
The PT-908 relay module can be cabled to the PT-811 to convert the voltage
outputs into relay outputs which can control powered devices directly.
The PT-811 modules are more expensive then the internal VG-IO modules, but
are very useful when the devices to be connected are positioned at a
distance from the PC or when you require more inputs/outputs than can be
obtained with the internal VG-IO cards.
Controlling High Speed Dome cameras
With the D-Vision XP and D-Vision RT software,
you can control the movements of High Speed Dome cameras, without then needs
of a dedicated external keypad.
The RS485 twisted pair cable, used to control the Speed Dome cameras is
connected to the COM port of the PC using interface SD-232485 (to be
purchased separately).
The cameras are controlled by the virtual Joystick on the right of the
screen, operated simply by using the mouse.
DSE Speed Dome cameras SD-22 and SD-27 can be fully connected right away,
and you can even pre-set the positions of the cameras using the software.
D-Vision also features the most common market protocols used to control the
most popular brands of SPEED-DOME cameras.
SD-232485 – Serial interface
 D-Vision
software can interface with external units such as speed-dome cameras and
input/output modules. These are connected by means of a simple twisted pair
cable using serial connection RS-485. Unlike the common RS232 format used
for serial connections between PCs, the RS485 BUS can be used for cabling up
to 1200 metres.
If your PC only has RS232 ports (as in most cases) you will need to purchase
an SD232485 converter which you can insert directly into the COM serial
port, enabling you to connect the twisted pair cable directly to its
terminal board (A/B).
Product package
The order code includes the PCI card,
installation CD and PDF manual.
The CD contains the drivers for the card, the D-Vision software which allows
operating all functions, and the D-Vision Server software which enables you
to connect remotely via LAN or the Internet (this is not needed for remote
connections via modem).
The D-Vision software also includes the DV-Player for VGZ files, which lets
you view recordings without installing the D-Vision software, and can
convert VGZ files into AVI format.
The package also includes the cable for connecting the watchdog, if
required.

The main functions
|
Multi-function monitor |
Real-time viewing of one camera full screen,
or more than one camera (up to 16), including images from remote PCs.
Sequential scan mode also available. Date, time, name of camera and card
can be displayed on screen in the colour of your choice. Digital zoom
on recorded images. |
|
Video recording
|
Each camera records practical compressed files, the
length of which can be programmed, and which are easy to consult and
store. The exclusive compression algorithm enables you to record
hundreds of hours of continuous recording onto a normal hard disk.
You can set aside a certain portion of the hard disk to ensure Windows
functions and the other software and use all the rest for recording, to
enable D-Vision to record uninterruptedly. You can set the dimension,
resolution and time lapse of the recordings in order to ensure the
recording time required will fit on your hard disk. D-Vision uploads
images at the outstanding resolution of 704x576. |
|
Audio |
D-Vision
records synchronized Video and Audio in the same file. You can also hear
the audio in real time from a remote connection. |
|
Transmitting recordings via modem
|
D-Vision lets you send
images to a remote computer via modem. D-Vision software must be
running on both PCs. You can select the cameras, set the viewing
parameters and activate the input and output module. |
|
Transmitting recordings via local network
(LAN) |
D-Vision
lets you send images to a number of remote computers connected in a
LAN network. This uses a server software which is included in the
D-Vision CD, and enables companies to set up a system with various
surveillance control points, using their existing LAN. |
|
Transmitting recordings via Internet
(TCP/IP) |
D-Vision
lets you send images to a number of remote computers connected via
Internet. This uses a server software which is included in the
D-Vision CD. We recommend you use a 24 hour ADSL connection, preferably
with a fixed IP address. Using this you can monitor your site from
anywhere in the world. The DV-Webcam plug-in means you can view camera
images using Internet Explorer without having to install the D-Vision
software. |
|
Remote controls |
Once you
have enabled remote access you can view camera images as you wish, but
also activate and deactivate outputs and control PTZ and dome camera
movements. You can also access the remote database and import films and
images. All of this without interrupting filming (Full Triplex) |
|
Motion detection and alarm triggers |
For each camera you can
set a range of sensitive areas (masks), which when modified (in the
event of an intrusion) trigger an alarm. This alarm can activate
a local WAV sound file, start recording, activate telephone voice
messages or send messages to a PC and outputs from the I/O module. You
can also software it to send out e-mails to ensure that films and images
will be safely stored on a remote computer. A sophisticated system for
setting the sensitivity prevents false alarms due to variations in
light. |
|
Activating and deactivating motion
detection |
The motion detection function can be
activated/deactivated according to a programmable calendar. You can also
activate motion detection by means of an external contact (with the I/O
module). |
|
Interactive maps |
The software handles customized maps (BMP
images supplied by the client) featuring icons of the various cameras.
The colour of the icon shows which cameras are recording, which are off
and where an intrusion has been detected. The maps are interactive and
enable you to view the film from any camera simply by clicking on the
icon. |
|
Access passwords |
Access to D-Vision can be controlled by various
levels of passwords with fine-tuning of level of access to the
system. |
|
Storage of alarm events and user access |
D-Vision
saves a record of each alarm event and user access, both local and
remote. This makes it easy to view the recording of each event. |
|
Recording calendar
|
Each camera can be set to record automatically
according to a programmable calendar. You can also activate
recording by means of an external contact. |
