GENEX SERIES MULTIPLEXERS
The MX4000 Genex
®
Series simplex and duplex multiplexers can accept video inputs from a
maximum of 9 or 16 cameras, depending on model. You can work in any of four languages:
English (default), French, German, or Spanish.
Duplex multiplexers let you view live video while simultaneously recording or playing tapes
using standard or time-lapse VCRs.
Simplex multiplexers have three operating modes:
• Live—The main monitor can show live video both in full-screen or multiple-screen
views. You cannot record in live mode.
• Record—The main monitor shows live video of an individual camera in full-screen
view only. You can record only in record mode. While recording, all cameras are being
recorded simultaneously.
• VCR—The main monitor displays full-screen or multiple-screen views of videotape
playback. You cannot record in VCR mode.
Simplex multiplexers can show video from the cameras on two monitors (main and spot)
while duplex multiplexers can show video from the cameras on three monitors (main, spot,
and auxiliary).
• The main monitor displays video from a single camera or from multiple cameras.
Video can be either live or from a tape playback. Multiple-screen displays can be
picture-in-picture, 4-, 9-, or 16-camera formats.
•A spot monitor displays live video from a single camera. A spot monitor is optional, but
increases the flexibility of your system. For example, you can keep an eye on all
cameras in a multiple-screen format on the main monitor while watching a full-screen
view of any one camera on the spot monitor. Or, if you are playing a tape on the main
monitor, you can use the spot monitor to watch live video.
• An auxiliary monitor also displays live video from a single camera. It also is optional,
but further expands the flexibility of your system. Again, you can keep an eye on all
cameras in a multiple-screen format on the main monitor while watching a full-screen
view of any one camera on the spot monitor. But suppose you are watching something
on the spot monitor and you do not want an alarm to occur and override what you are
watching on the spot monitor. Use the auxiliary monitor to display alarms.
Cameras can be sequenced on all monitors (the auxiliary monitor by programming only).
In full-screen view on the main monitor, a zoom function doubles or quadruples image size
for better viewing. This works only in full-screen view.
Depending on model, there are 9 or 16 alarm inputs–one per camera–that tag the camera
images when an alarm is activated. You can program main, spot, and auxiliary monitors to
display alarms. Alarm inputs also activate a relay output, which can be used to change a
VCR to its preprogrammed alarm record speed. When there is an alarm, the VCR
(depending on how it is programmed) will either record alarm cameras only or record both
alarm and non-alarm cameras. An alarm log lists the last 72 alarms.
Activity detection continually monitors selected camera inputs for activity. When the
multiplexer detects activity, it increases the frequency at which it records cameras with
activity. You can program main, spot, and auxiliary monitors to display cameras with activity.
