The“recordingbuffer”allowsusertodene“pre-alarm”and“post-

alarm” time for event recordings. The “pre-alarm” time sets the NVR

to record in advance when an event is triggered. The “post-alarm”

time sets the NVR to continue recording for a period of time after an

eventtriggerisnished.

Recording frame rate allows you to set different frame rate for dif-

ferent types of recording instead of recording at one frame rate only.

Use the drop-down menu and select one of the pre-dened frame

rates for a particular recording type

* The “Pre-alarm” function only

works when the “Continueous”

recording is also activated.

Users can also set to keep a previous number of days of recording

data by enabling the option below. This is quite often used in applica-

tion such as banking which certain countries requires to always keep

a minimum previous number of days of recording data.

* If this option is enabled, once the hard drive is full, the recycle function will

then start but it will ensure that the number of days of recording data dened

here will stay in hard drive instead of wiping out 20GB of data at a time.

* If the hard drive is not full, the NVR re-calculates twice a day (each at

2:30am and 2:30pm) to keep the dened number of days of recording data

from these two particular point of time backward.
