Record: Mainstream (3 Megapixel)
Channel: Select a camera that you would like to edit.
Resolution: By default, the recording resolution is automatically selected to
match the native 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 capability.
FPS: The number of frames per second (fps) that your DVR will record. The
default is 7fps, 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 (low-
ering the frame rate to 4fps 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 decrease 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 recording will
have an effect on image quality, bandwidth consumption, and hard drive stor-
age. 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 complex scene with little action or movement.
