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.

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.

3.4 RECORDING

Your DVR is factory set to record when motion is detected. Most users prefer this as it means that

it is easier to locate an event using the Search function (see Section 3.5) and it will take longer

before the DVR will need to overwrite older ﬁles on the hard drive. You can override this in the

Record menu, as discussed below, or you can schedule the hours when the NVR captures motion.

MANUAL RECORDING

This window allows you to override the scheduled recording times of selected cameras. You can

access the Record Menu via the Shortcut menu or by pushing the Record button on the remote.

There are three status modes: Schedule,

Manual and Stop. The status of each

channel is shown by the ﬁlled circle under

its number. Each camera can only have one

status at a time. Changes take effect once

the OK button is selected.

Manual – The selected cameras will begin

recording

Schedule – Cameras record based on your

settings made in the Schedule Menu or

Detect Menus (See Sections 3.6 and 3.7

respectively)

Stop – All selected cameras stop recording

You can assign the same values to all cameras by selecting the desired status in the “All”

column.

Resolution – Depending on your model, your system will support recording and playback of

video at four different resolutions:

CIF: 352x240 pixels 2CIF (also known as HD1): 720x240 pixels

D1: 720x480 pixels 960H: 960x480 pixels

A comparison is shown below (at 33% actual size). Each resolution encompasses the area of

the smaller resolutions in addition to the area labeled.

The larger resolutions will require more storage space on a hard drive than the smaller formats.

On some systems, there is also a trade-off during recording or playback where the larger

formats will need to be played back or recorded at a reduced frame rate than the smaller ones.

This is especially true when multiple videos are being played back at the same time.

The Extra Stream can only use the CIF resolution.

The Specifications pages in the back of this manual contain information about your DVR’s

recording resolution capabilities.

Frame Rate (FPS) – Variable between 1 to 30 frames per second. The higher the number, the

smoother the playback.

Bit Rate Type – Variable versus Constant. Variable provides better compression, but issues

may arise when streaming for remote viewing.

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.

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.

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.
