4. ALARM RECORD RATE:
For an NTSC unit we provide many different speeds ranging from 0 to 60 frames per second, and
for a PAL unit the figures are from 0 to 50 F/S.
5. ALARM RECORD MODE:
The recording images of the specific channels are much needed when the alarm sensor or motion
detection is working. Each channel is provided with four levels of alarm record rates: NORMAL,
DOUBLE, INTERLEAVED, and EXCLUSIVE, and each provides a different specific gravity of
recording:
NORMAL: The alarm record priority is off.
DOUBLE: The recording images of the specific channels are doubled.
INTERLEAVED: Interleaves the images of the specific channels with the normal recording.
EXCLUSIVE: Only records the channels where the alarm sensor or motion detection has been
activated.
If / when your DVR is connected to four cameras, you have the following four options in settings:
Normal, Double, Interleave, and Exclusive. Let us show you how they operate by giving the
following example.
Say an alarm occurs in the camera 1 zone (channel 1):
1. Normal: This mode will display the channels in their normal numerical sequence, as follows:
channel 1 - channel 2 - channel 3 - channel 4, and then repeat this above sequence indefinitely.
2. Double: In this mode the display will start with a double display of channel 1, followed by a
display of the other channels in their usual numerical sequence, as shown below:
channel 1 - channel 1 - channel 2 - channel 3 - channel 4, and then repeat the above sequence
indefinitely.
3. Interleave: This mode displays the channels in a sequence that alternates the channel 1
display with a display of each of the other channels, as follows:
channel 1 - channel 2 - channel 1 - channel 3 - channel 1 - channel 4, and repeat the above
sequence indefinitely.
4. Exclusive: This mode will display only channel 1 exclusively and exclude the display of all the
other channels, as follows:
channel 1 - channel 1 - ... indefinitely.
6. ALARM RECORD QUALITY:
Similarly enter and set each channel to record an alarm at qualities ranging from BEST, HIGH, and
STANDARD to BASIC.
