The QR4x and QR8x quads are the devices enabling the simultaneous displaying
of 4 cameras on one monitor. The QR8x quad also offers the possibility displaying of the 2
pages of 4 cameras. The refresh sequence of displaying cameras is 50/60 fields/s.
The QR4M and QR8M quads have one MAIN and one SPOT video output. The MAIN
video output is used for connecting a monitor and enables either the displaying of split
screen, or particular cameras in full size. The SPOT video output is used only for the
displaying of split digital picture and is usually used for recording to the time lapse
recorder. The QR4C and QR8C quads have also one S-VIDEO output that is identical to the
MAIN video output.
The QR4x and QR8x also contain the well-arranged setting menu, which can be
used for easy settings of all parameters on the display.
The QR4x and QR8x have one alarm input for each video input. After the alarm
input is activated, the relay contacts are switched ON. The relay contacts are lead out to
the alarm connector. The alarm can be active during the whole time, when the alarm input
is active, or in the interval from 2 to 255 seconds since the activation. The alarmed
camera is displayed on the whole screen, as long as the alarm lasts. The alarm is
signalled acoustically too.
The QR4x and QR8x enable the manual or automatic switching of particular
camera and quad pictures on the MAIN monitor output. The quads automatically switch
according to the programmed sequence, where can be set up the order and time of switching
camera. The switching time can be set up within from 1 to 255 seconds. The switching
sequence is programmed with the help of on-screen menu and can be of 16 steps at maximum.
