Record: Mainstream (720p model)
Channel:
Select a camera that you would like to edit.
Resolution:
By default the recording resolution is automatically select-
ed to match the capabilities of the provided cameras. If you have an
older analogue camera connected, lower the resolution to “960 x 480”
for NTSC and “960 x 576” for PAL, to match the camera’s recording ca-
pability.
FPS:
The number of frames per second (fps) that your DVR will record.
The default is 25fps, however you can change this if needed. In the
HomeSafe View app, you can select “Mainstream” in Live mode to view
your cameras. Lower the frame rate if you’re having issues streaming
to your mobile device (lowering the frame rate to 15fps for example, will
reduce the bandwidth required without sacrificing image quality).
Bitrate Control:
CBR (Constant Bitrate) utilises a fixed bitrate and band-
width to record video. This means your DVR will use the same number
of bits throughout the entire recording, regardless of what is happening
on-screen. VBR (Variable Bitrate) utilises a bitrate and bandwidth that
changes when your DVR is recording. The bitrate will increase or de-
crease depending on how complex the scene is.
Which method should I choose?
Scene complexity can vary significantly
over several hours of recorded video, and the bitrate you select for re-
cording will have an effect on image quality, bandwidth consumption,
and hard drive storage. A complex scene with moving action, such as
traffic on a city street, or a scene with a lot of contrasting colors, will
affect image quality and bandwidth consumption more than a less com-
plex scene, such as an interior room with very little action or movement.
