JVC VR 601 instruction manual PRE- Alarm

PRE- ALARM:

This option determines that images prior to an alarm occurs will be recorded in the hard-disk drive. When an alarm is triggered the device will record the image prior to the alarm for 5 seconds in NTSC (**20 fields/sec) or 6 seconds in PAL (**17 fields/sec).

ON: Enables this function.

OFF: Disables this function.

NOTE: If the device is already under recording mode before alarm occur, the pre-alarm recording would not take effect.

**: For NTSC and Mux Off Mode, recording rate 20F/S would be actually 15 F/S For PAL and Mux Off Mode, recording rate 17F/S would be actually 12.5 F/S.

( This adjustment is to avoid image shaking during playback at the same speed )
