Record Mode: 2 record modes are available.
Normal + Event: This recording mode includes continuous and event recording.
Event Only: Video will be recorded only when events occur.
Record Dual Stream: Select "Enable" to record dual stream. Select "Disable" to disable this function.
Resolution (Main Stream): Select recording resolution based on video format for main stream.
NTSC: 704x480 / 704x240 / 352x240
PAL: 704x576 / 704x288 / 352x288
Resolution (Sub Stream): Select recording resolution based on video format for sub stream.
NTSC: 352x240 / 176x120
PAL: 352x288 / 176x144
Record Quality (Main Stream / Sub Stream): Select an image quality for recording. There are five
different qualities available: Superior, High, Standard, Basic and Low. A higher image quality uses more
HDD space.
Normal Speed (Main Stream / Sub Stream): Frame rate in frames (images) per second (FPS) for
continuous recording. The speed is limited by the maximum total recording capacity of the DVR as
allocated across all the installed cameras, with an upper limit of 30 FPS (NTSC – 25 PAL) per individual
camera (real time recording). The DVR is capable of recording 480 CIF (352x240) sized frames per second
(NTSC; 400 PAL); each 704x240 image (2 CIF) per second requires allocation of two of those CIF frames
from the overall capacity of 480 CIF frames, and each 704x480 image (D1 or 4 CIF) per second requires
allocation of four of the CIF frames from the overall capacity. Thus the DVR can record a combination of
CIF, 2 CIF and 4 CIF images, with different combinations of image size/resolution and different FPS rates
on different cameras, so long as the total CIF equivalents allocated is not greater than 480 CIF per second.
Choices for possible record speeds are 30, 15, 10, 7.5, 5, 3, 2 and 1 FPS.
Examples:
16 cameras at CIF resolution at 30 FPS: 16x30=480 FPS
2 cameras/4CIF/30FPS plus 5 cameras/2CIF/15FPS plus 9 cameras/CIF/10FPS:
2 cameras/4CIF/30FPS plus 2 cameras/2CIF/30FPS plus 12 cameras/CIF/10FPS:
In these examples, the recording capacity of the DVR is fully allocated to normal recording, with no reserve
capacity for increasing image size and/or FPS rate in response to a motion or alarm event (see next item).
2x4x30+5x2x15+9x1x10= 240+150+90 = 480
2x4x30+2x2x30+12x1x10= 240+120+120 = 480
