SW-D7000U, 9CH. COLOR VIDEO MULTIPLEXER
JVC PROFESSIONAL, IMAGING PRODUCTS 55
If EXCLUSIVE alarm recording is selected, then the alarm-input sensors used need to be:
"
very comprehensive, so that alarm events are not missed, and
"
reliable, so that the system does not start exclusive alarm mode recordings for false alarms.
NOTE:
If only one camera is in alarm and the alarm speed is set to the 2 hour mode, then the
unit will automatically select INTERLEAVED recording even though
EXCLUSIVE mode is
selected.
Interleaved:
During INTERLEAVED
recording both the alarmed cameras and non-alarmed cameras are recorded,
but alarmed cameras, having a higher priority, are interleaved between non-alarmed cameras.
INTERLEAVED mode offers increased recording of cameras in alarm, without stopping the recording
of other cameras. This is the mode recommended for most installations.
Example:
Non-alarmed cameras: 1,2,3,5,7
Cameras in alarm:
4,6
INTERLEAVED recording sequence:
1,4,6,2,4,6,3,4,6,5,4,6,7,4,6,1, ....etc.
NOTE:
Because of the fast update rate of the SW-D7000U, if one camera is in alarm then
INTERLEAVED
mode will result in real-time Playback of the camera in alarm. In
general, on the SW-D7000U, INTERLEAVED
recording will give very fast update speeds
of cameras in alarm even for multiple alarms.
INTERLEAVED
mode is the
recommended setting.
ENABLE / DISABLE
Any alarm input can be set up as being active (enabled) or inactive (disabled). In this option you may
select:
INDVIDUAL ENABLE
ENABLE ALL
DISABLE ALL
ALARM HISTORY
An alarm history is kept in a cyclic buffer. History data, including camera number and time and date
is kept in memory for up to 100 events. The most recent 100 alarm events can be viewed on-screen
in the menus, by selecting the ALARMS menu and then selecting ALARM HISTORY. A table will
appear, allowing the programmer to browse forward and backwards among the last 100 alarmed
events. Each event relates is recorded with the Alarm #, Date, Time and Relay #. The RS-232
remote control capability also allows an operator to upload the alarm history to a PC or a similar
controlling device.
LINK TO A MACRO
Any alarm input can be linked to any macro function. This can be used to start a pre-programmed
sequence of keystrokes each time an alarm occurs. Several alarm inputs can be linked to the same
macro function. To link alarm inputs to macro functions, use the LINK TO MACRO menu in the
ALARMS sub-menu.
