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 08:30 as the first time and 17:30 as the second time. This makes the

timer active during the daytime.

If on the other hand you wish to specify an inactive period during the day, enter 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 inactive between 08:30 and 17:30.

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, enter: 00:00 23:59

• Typical Working Hours (08:30 to 17:30), enter: 08:30 17:30

• Morning and evening (00:00 to 08:30 and 17:30 to 00:00), enter: 17:30 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, enter: 00:00 23:59

• Typical Working Hours (08:30 to 17:30), enter: 08:30 17:30

• Morning and evening (00:00 to 08:30 and 17:30 to 00:00), enter: 17:30 08:30
