YS-DX504P
Duplex Multiplexer
The Sony YS-DX504P Duplex
Multiplexer is designed for use
in multiple-camera monitoring
and recording systems. This
unit allows up to 4 video
channels to be displayed
on a single monitor.
The YS-DX504P provides a
high level of functionality in
surveillance systems. Features
include sequential switching,
picture zoom and freeze, and
a full range of alarm functions.
This model is equipped with
an RS-232C interface, allowing
it to be remotely controlled by
an external computer.
With these and many more
features, the YS-DX504P
multiplexer can make an
important contribution to
efficient and effective
monitoring and recording
in surveillance systems.

Powerful alarm functions
Alarm functions are indispensable in surveillance systems. The YS-DX504P incorporates a number of powerful
alarm functions and these can be tailored to optimize the information displayed to the operator.
External alarm
Activity detection
The YS-DX504P provides 4 alarm inputs - one for each
corresponding Camera Input connector.
The operator can designate one sensor point per camera
anywhere on the screen. If the brightness level at this point
changes, an alarm is initiated and the Active Recording mode is
triggered. An important feature is that a sensor point can be
allocated such that it senses change in ambient light to avoid a
false alarm being triggered. The overall sensitivity of the sensor
point can be set for both day time and night time conditions.
External alarm inputs also trigger the Active Recording mode.
When an input alarm signal is received, the associated
video input is displayed. The display on Monitor 1 can be
pre-selected from one of the following two options:
A) Full screen
When an alarm trigger is received, the picture from the
camera corresponding to the alarm input is displayed in full
screen.
B) 4-division split screen
When an alarm trigger is received, the display switches to a
4-division split screen.
(Video sensor alarm)
Recording modes:
Mode 1: The video signal from the alarmed camera is recorded
exclusively.
Mode 2: Recording of the video signal from the alarmed camera
alternates with sequential recording of the remaining cameras.
Sensor point
When an input alarm signal is received, the associated
video input is automatically displayed in full screen on
Monitor 2. When two or more alarm triggers are received
simultaneously, Monitor 2 sequentially displays the images
from the cameras corresponding to the alarm triggers.

Video Loss alarm
Recording duration
The illustration below shows outputs of all the cameras
recorded during daytime, but only cameras showing a moon
(1, 3) are also recorded at night.
If any of the input video signals are lost, a buzzer sounds and
an LED associated with the failed camera input flashes. If a
split-screen display is being viewed on the Monitor 1 screen,
the most recent image of the lost signal is frozen, with the
words “Video Loss” flashing. When a full-screen display is in
use, Monitor 1 continues to display the selected camera. If this
is the camera that has failed, then the image is frozen and the
flashing “Video Loss” message is displayed.
Sensitivity
Individual alarm duration/output
The sensitivity range of the video alarm sensor can be
changed to accommodate day and night time light levels.
The duration of an alarm event can be individually set from 1 to
180 seconds for each camera.
The recording time of each video camera can be
programmed individually. You can increase or decrease the
number of cameras recorded according to the time of day.
