CHAPTER 5  MENUS

This window allows you to manage the quality of the recording from each channel as well as 
the transmission rate and whether there’s an accompanying audio feed.
 

As with other windows described earlier, 
each channel can be set individually or all at 
the same time. Settings can be copied from 
one channel and pasted to another. Only by 
hitting Save will your settings be retained. 
Right-clicking or hitting Cancel will leave the 
system with your previous settings.
The system is configured to record using the 
H.264 format and this cannot be changed.
In addition to the settings for display on the 
DVR, you can also adjust the settings for 
the sub-stream display, referred to as Extra 
Stream 1 in this window. This stream is 
the data that is sent to remote monitoring 
devices. Due to bandwidth concerns, these 
data streams are generally smaller than those 
sent directly to the DVR itself. These streams 
run in parallel with the main stream sent to 
the hard drive and they do not affect each 
other.

Resolution – This system supports the D1, CIF or QCIF recording format. D1 is equivalent to 

full TV resolution at 704x480 pixels and offers the best resolution at the cost of taking 
up the most disk space. CIF is roughly one-half the resolution of D1 at 352x240 and 
correspondingly takes up less room on the drive. QCIF is smaller still at 176x120 
pixels. 

The Extra Stream can only use the QCIF resolution.
Frame Rate (FPS) – Variable between 1 to 30 frames per second. The higher the number, the 

smoother the playback.

NOTE! Generally, the trade-off for higher quality and increased frame rate is 
the amount of room a video file will take on the drive along with how much 
“bandwidth” the signal takes up within the system. This system cannot record 
with all channels set to maximum resolution and frames per second and it will 
limit you to one channel set at D1 recording at 30FPS with all other channels 

Bit Rate Type – Variable Bit Rate (VBR) versus Constant Bit Rate (CBR). VBR provides better 

compression, but issues may arise when streaming for remote viewing.

Quality – Only enabled when VBR is selected, this can be set from 1 to 6 with 6 having the 

highest image quality.

Bit Rate (KB/S) –Configurable from 192 to 1024 kilobytes per second, this is the maximum 

bit rate the selected channel can utilize. Your network may not have enough 
bandwidth to handle maximum rates from all of your cameras. Adjusting these 
settings to suit your network will improve performance and on-screen image quality.

either being limited to CIF at 30FPS or less, or D1 with a maximum frame rate of 7FPS.

Audio/Video – Selecting this box adds an audio feed (if you have a microphone located at 

or near the camera). On the Extra Stream, you can enable the  Audio (first box in that 
column) only if the Video box is also toggled.

Overlay – This window allows you to mask off areas from view.  This is useful in 

circumstances such as when a camera’s field of view includes a combination lock or 
other similar situation.

You can mask up to four areas in each 
camera’s field of view in two modes. Preview 
mode blocks the area for both local and 
network viewers. Monitor allows the local 
user to view the area but remote viewers 
cannot see the area. These privacy blocks 
affect both the live view and playback. You 
can select either or both allowing you to 
block selected areas for one set of viewers 
but not others.
Clicking any of the numbered boxes will 
create a black area in the upper left corner of 
the screen. If you select more than one, they 
will all be located in the same place. Clicking 
on the Set button will hide the Overlay 
window and give you a view of that camera’s 
video feed along with the black box(es). The 
active box will be outlined in green and you 
can switch between boxes by clicking on 
another one. Each box will have its number 
inside. It can be moved and sized as needed 
using the mouse.  Right-clicking on the 
screen will return you to the 

Overlay window.

Time Display – This allows you to display the 

system time on the channel’s screen 
during playback or not. In addition, 
by clicking the Set button, the time 
display can be relocated anywhere on 
the screen by clicking and dragging. 
A “Before” and “After” example is 
shown in 

Picture 5-16

.

Channel Display – Like time display, this toggles the appearance of the channel’s number on 

the screen during playback as well as allowing it to be repositioned in a similar fashion.
