MVS-14 video-servers are used to
connect any analogue camera from the DSE range directly to a TCP/IP network,
like a LAN network or the internet.
Introductory information
The differences
between analogue and digital cabling
In traditional analogue cabling cameras are connected using coaxial
cables which carry video signals to monitors and video recorders.
In IP
cabling, an MVS-14 video-server is positioned beside each camera. This
has BNC connectors for analogue video on one side and a network connection
(LAN, WAN or Internet) on the other side. The video server converts the
video signal into digital format, thus enabling it to be visualized from any
PC in the network, simply by using a browser like Internet Explorer.
The differences
between video-servers and "IP cameras"
On the
market there are cameras known as “IP cameras”. These are nothing more than
an
analogue camera and a video server inside the same housing. DSE does not
incorporate its video servers into its cameras for the following
reasons:
By
using a separate video server you can select the camera which is most suited
to the application in question (low-budget, high resolution, low-lux, with
IR illuminator, waterproof, vandal-resistant, mini-cam, etc.).
By using a
separate video server the camera can be installed at a certain distance,
which is indispensable in tight spaces, or when hidden cameras are needed.
With a
separate video server it is possible to use wireless cameras, linked via
radio.
The
differences between video-servers and digital video recorders with remote
access
The most
advanced DSE digital video recorders, like those in the
D-Vision
range,
easily perform all the functions of a video server, as they are
network-enabled and allow remote access by TCP/IP. It is therefore possible
to create a modern CCTV system over IP in two ways:
By
using cameras linked with coaxial cable to one or more D-Vision digital
video recorders connected to an IP network.
By
using cameras with individual MVS-14 video-servers directly connected to the
IP network. Images are recorded using software installed on PCs in the
network.
The
choice between these two solutions depends on cost factors and questions of
convenience/feasibility of cabling.
How the MVS-14 video-server works
Easy
installation
The MVS-14
video-server is a compact (120x146x46 mm.), completely autonomous unit. On
the camera side it has 1 video input and 1 audio input which can be linked
to any DSE camera. It also has an analogic video output to carry the video
signal towards any other devices required. On the network side it has an
RJ45 connector for the LAN network, the connection for the 12VDC power
supply (power pack included), and an RS485 port which can be used for
conveying commands to SD Speed Dome cameras.
Wi-Fi
version
The Wi-Fi version MVS-14W is available for
connection to wireless LAN IEEE 802.11g. The device includes the site survey
feature that detects all available access points in the area. The
MVS-14W video server supports WEP encryption to protect the video streaming
from unauthorized access.
Instant
configuration
Once the
LAN network is connected you can set the IP address of the video server. We
provide an IP INSTALLER software which enables any PC in the network
to detect the video servers present in the network, and configure the
factory-set IP address as you wish.
LAN
access with Internet Explorer or Quicktime
Camera images can be visualized from any PC in
the network, just by entering the IP address of the video server into the
address box on Internet Explorer. A clear Active-X graphic interface enables
you to visualize the images from the camera linked to the video server, or
even a simultaneous quad image with images from up to 4 MVS-14 video servers
in the network.
All the settings of the video-server can be modified on the
password-protected configuration pages. Instead of Internet Explorer, the
Quicktime free player could also be used to connect to MVS-14.
Internet
access with Internet Explorer or Quicktime
If the LAN network is connected to the
internet you can also access the video server remotely, in the same way as
you would from the LAN network. The video server can also be installed by
connecting it directly to a router and to the net via the router, without a
network of other PCs.
With internet connections it is preferable to use a fixed IP address, though
the MVS–14 also supports DDNS services, which enable variable IP addresses
to be used.
Main features
Dual-codec MPEG4 –
MJPEG compression
Unlike most of the video servers on the market, which use MJPEG
compression, the MVS-14 contains a hardware compression chip which transmits
streaming in MPEG4 format (at constant or variable bitrate). MPEG4
compression enables large images and a high number of frames to be
transmitted without occupying great bandwidth.
Full D1 resolution
720x576 pixels
MVS-14 offers D1 resolution - 720x576 pixels (DVD quality). The
images transmitted via web are high resolution, full-screen and zoomable.
The use of full D1 resolution is the main feature that makes the MVS-14
video server stand out from most of the competing products in this price
range, which use less advanced acquisition chips, and deliver a
disappointing little window in low resolution.
Frame Rate of 25
frames/second in real time
Thanks to the use of MPEG4 compression the video streaming is
smooth and never jerky, even at maximum D1 resolution.
High quality real time images guaranteed.
If you have already experienced the frustrating sensation of using cameras
on IP where you have to lower the resolution to avoid getting a jerky image,
the MVS-14 will change your opinion of video transmission on IP.
Long-term operative
stability
The main parameter to take into account when choosing an IP video
server is operative stability. With video over IP there is nothing worse
than a system with unstable digital conversion, subject to regular crashes
and needing to be rebooted from the power supply to function once more.
The firmware of the MVS-14 video server undergoes lengthy testing and
careful beta-testing before each new release. You can confidently install
the device even in out of the way positions, safe in the knowledge that you
will not need to intervene again.
Firmware updates can be downloaded via FTP from any PC in the network.
Synchronized audio
The video-server has an audio input for transmitting PCM compressed audio
signals. The audio quality is maximum fidelity, without gaps or interference
of any kind. The audio is reproduced on the remote PC perfectly in sync with
the video images, without any delays or echoes caused by IP transmission.
PTZ commands for
speed dome cameras
MVS-14 has an RS485 port which means it can also be used for
speed dome cameras, which can be controlled via internet explorer. The most
common communication protocols are included: PELCO P/D (DSE SD range of
cameras), Lilin, Dynacolor.
User control
This is password-protected for up to 10 remote users, with
scheduled access. There is a supervisor password for modifying the
configuration.
Motion detection
The video-server also has a motion detection function which
allows images to be sent via email or FTP in the event of intrusion.
Recording software
Unlike analogue systems that need all cameras to be connected to video-recorders, in IP CCTV the video-recording is usually operated over the network by IP surveillance software.
DSE range include 2 powerful products for IP video recording:
SCB-IP - 16 channels surveillance software suitable for DSE IP cameras and video servers only
SCB-IP PRO - 64 channels surveillance software suitable for most IP cameras on the market today.
DSE IP cameras and video servers are also compatible with most multiprotocol IP surveillance software on the market.
