The
Digital
BUS-WATCH®
R1001 Single Channel DVR default settings are for
the best video quality (and least amount of record time) which is configured with a
resolution of D1, a record Quality of 1, and a Frame Rate of 30 FPS; as shown in Figure
66 on Page 66. For the Digital BUS-WATCH® R4001 4 Channel DVR, there is a
maximum bandwidth that can affect how the DVR is configured as shown in Figure 65
above. If the DVR is set to record at a resolution of D1, the maximum frame rate for
each of the 4 cameras is 8 Frames Per Second (or 30 frames composite). If the DVR is
set to record at a resolution of HD1 (or ½ D1), the maximum frame rate for each of the 4
cameras is 15 Frames Per Second (or 60 frames composite). If the DVR is set to record
at a resolution of CIF (or ¼ D1), the maximum frame rate for each of the 4 cameras is 30
Frames Per Second (or 120 frames composite).
When using the Digital BUS-WATCH® R4001 4 Channel DVR
with only 3
cameras, the group resources are the same as with 4 cameras. The 3 cameras must
conform to the same group resolution, quality, and frame rate resource pool. However,
record times are longer with any given size hard drive when using 3 cameras as opposed
to 4.
When using the Digital BUS-WATCH® R4001 4 Channel DVR
with only 2
cameras, the group resources can now be split differently. If the DVR is set to record at a
resolution of D1, the maximum frame rate for each of the 2 cameras is 15 Frames Per
Second, if the DVR is set to record at a resolution of either HD1 or CIF the maximum
frame rate for both cameras is 30 Frames Per Second; as shown in Figure 67 on Page 66.
