10.4.1 Date and Time
10.4.1.1 Summer/Winter Time
When the clocks change between wintertime and summertime, the
DATE/TIME
setting must not be
changed. Instead, the Summer/Wintertime setting should be used. In the UK and the rest of Europe, the
default
AUTO Summer/Wintertime setting ensures that this happens automatically at the correct dates so
the user requires no action.
10.4.1.2 Date/Time (DD/MM/YY HH:MM:SS)
For proper operation of the VDM Digital Recorder is essential that the date and time are set correctly. If the
displayed date and time is incorrect, set it as follows:
Use the 1-10 keys (10 key is Zero for numeric entry) to enter the date and time in the following order: Day,
Month, Year, Hours, Minutes (Time is in 24-hour mode). The displayed day and summer/winter-time must
also be correctly displayed (automatic).
10.4.2 Timers
Each of the timers has a start and end time for each day of the week so any period of each day may be
specified. For example you might enter 80:30 as the first time and 17:30 as the second time. This makes the
time active during the day.
If rather than a specifying single period during the day, you wish to specify a nighttime period that overlaps
one day to the next, entering the latest time
first and the earliest time last . For example, if you enter 17:30 as
the first time and 08:30 as the second time, the timer will be active from 17:30 in the evening to mid-night
and from mid-night to 080:30 in the morning.
10.4.2.1 Custom Recording
This timer is used in conjunction with the Custom record settings (section 10.4.3.2). Custom record settings
apply during the specified time periods.
Examples:
•
All Day: 00:00 to 23:59
•
Typical Working Hours 08:30 to 17:30
•
Typical Night time Hours 17:30 to 08:30
Custom recording can be used for a number of purposes, two in particular:
•
To increase recording rates to a defined frame rate during specific peak periods. Note that more
hard drive space will be used, and that the update rate under Normal recording conditions will be
reduced. If too high a rate is specified for too long, it may be impossible for the system to attain the
specified image retention period (section 10.4.3.1.1).
•
To decrease recording rates to a low level during off-peak periods. This will free up more hard drive
space for Normal recording periods and therefore increase Normal recording update rates. For a
given image retention period. If cameras are turned off (Section 10.4.3.2.2), then no recording will
occur during the programmed Custom recording periods.
10.4.2.2 Alarms Enable/Disable
Alarms are enabled for particular times of day, for each day of the week
Examples:
•
All Day 00:00 to 23:59
•
Typical Working Hours 08:30 to 17:30
•
Typical Night-time Hours 17:30 to 08:30
