【
Channel
】
Select “All” to adjust all channels at the same time, or use the drop list to select a
particular channel.
TIP:
Most installations have similar settings for all cameras. Use the “All” selection first, set
your parameters, SAVE your settings, then go back and edit individual camera channels to
customize the system to your needs.
【
Encoding Type
】
Affects the resolution of the recording. CIF has the lowest resolution, but
uses the least amount of hard drive space, D1 is considered “full resolution” and consumes
more hard drive space, 960H is an expanded wide screen resolution and consumes the most
hard drive space.
【
Frame Rate
】
Select 1 to 30 frames per second. More frames recorded per second requires
more hard drive space. Use 30 frames to record fast moving activity or to capture subtle
changes. 15 frames per second is fine to capture a person walking without a noticeable jitter,
and a few frames per second is enough to notice normal changes in a scene.
【
Encoding Mode
】
CBR (Constant Bit Rate) is used when the internet connection that will
transmit the recorded video is slower than normal. VBR (Variable Bit Rate) is the most
popular selection, and performs well with most high speed internet connections.
【
Image Quality
】
Image quality is purely a judgment call. Select from five options, again the
highest setting consumes the most hard drive space, and the lowest uses the least amount.
Most people will start with the highest setting, and eventually lower a non-significant channel if
more recording time is preferred before the hard drives overwrites (loop records over older
video).
【
Pre-Alarm Rec
】
Is a very useful feature if you are event recording with the video motion or
alarm features. Pre-alarm record will store a short segment of video before a trigger (event)
occurs, and later show on playback the activity that happened just before the trigger occurred.
【
Audio
】
(Optional) Select “Open” if a microphone or camera with audio is connected to the
channel.
