If you install a surveillance system
with just one camera all you need to do is connect it to a monitor or TV to
view the images. But if you have a number of cameras then you will need a
device that enables you to select and manage the images efficiently. There
are three types of devices for this:
 VIDEO
SWITCHERS
take several hard-wired video inputs and have a keyboard which
enables you to select which camera to view on screen, or shows them all in
rotation. DSE do not produce anymore video switchers since they have been replaced by quad's in small systems and DVR's in larger systems.
QUAD
SPLITTERS take up to 4 hard-wired video inputs. As well as acting
as a video switcher, a quad is used to split the TV or monitor screen into 4
quadrants and view images from 4 cameras simultaneously. The image
containing the 4 camera views can also be recorded.
MULTIPLEXERS
perform all the functions of quads and switchers and also enable you to
record images from all the cameras simultaneously using a time-lapse cassette video
recorder.
QUAD SPLITTER
for viewing images from 4 cameras on a single monitor
|
QUAD SPLITTER
A quad splitter is a device which enables you to view images from
4 cameras simultaneously on one single monitor or TV. Positioned
alongside the monitor, it divides the TV or monitor screen into 4
quadrants and shows images from one camera in each quadrant. The
advantage lies in being able to monitor 4 different areas at the same
time, with the option of pulling up a full-screen view from a specific
camera at any time.
DSE quads also offer switcher functions, thus delivering three types of
viewing: quad, full screen single camera image, or camera views in
rotation.
On the front of the device are buttons numbered 1-2-3-4 to select each
camera, as well as the quad button and switcher button. DSE quads are
suitable for both black/white or colour cameras, logically without audio
input.

How is a QUAD
connected?
A quad has 4 video inputs (with BNC connectors), each of which
connects to a camera. Traditional hard-wired cameras can be connected
directly to these outputs, while RadioEye® wireless cameras require a
receiver for each camera (4 receivers in all), each of which delivers the
video output from one camera. For ease of use with 4 separate receivers, it
is advisable to opt for
 receivers
without control panels such as
RE-RX3, not much bigger
than a cigarette packet, which can easily be placed by the quad. The quad
has a video output for the monitor and one (with fixed quad image) for video
recording devices.
We also offer a 9 PIN connector which takes 4 alarm inputs, from sensors or
switchers for example. When an alarm is activated the camera in question is
pulled up to full-screen.
Multiplexers for recording images from 4 or 8 cameras simultaneously
|
MULTIPLEXERS
If you send output from a switcher
or quad to a time-lapse video recorder it will record exactly what is
shown on the screen, therefore, depending on what was selected, a single
camera, quad or sequential scan.
If you wish to record images from all the cameras at the same time there
are 2 options: buy a DVR or utilize a multiplexer with your time-lapse
video recorder.
DSE offers black/white or colour multiplexers with 4 video inputs.
Modern Digital Video Recorders do not require multiplexers having multiple video inputs. |
technical data |
Multiplexers connect to a TV or
monitor, and like a quad, enable you to view images from up to 4 cameras at
the same time, dividing the screen into 4 quadrants. The multiplexer also
functions as a switcher, offering timed rotation of the cameras or the
option of viewing one single camera full screen.
The key function of the multiplexer is when connected to a time-lapse video
recorder with cassettes. The multiplexer transmits one frame from each
camera in rapid succession and then in playback mode selects all the frames
from one camera and shows them as a single recording.
During playback you can select images from each camera using the keyboard or
view them all simultaneously, like a quad. Although only one video recorder
is used, you will be able to record images from all cameras, as if you had 4
or 8 video recorders, each one linked to a camera.
How is a multiplexer connected?
A multiplexer has 4 video inputs, each of
which connects to a camera. Hard-wired cameras can be connected directly to
the multiplexer, while if you are using RadioEye® wireless cameras you will
require a receiver for each camera (4 receivers in all), each of which
delivers the video output from one camera. For ease of use with 4 separate
receivers, it is advisable to opt for receivers
without control panels such as RE-RX3, not much
bigger than a cigarette packet. The multiplexer is connected to the
time-lapse video recorder with one outbound and one
inbound cable.
We also offer a 15 PIN connector which takes 4 alarm inputs, from sensors or
switchers for example. When an alarm is activated the camera in question is
pulled up to full-screen
