Resolution
You can set the recording resolution for each camera from the Resolution drop
down list. The resolutions available will depend on the camera.
A higher resolution will record higher quality footage but takes up more storage
space.
Frames Per Second (FPS)
The frame rate is how many images are captured per second and determines how
smooth your recorded footage appears. You can set the frame rate in the FPS drop
down list.
A higher frame rate produces smother footage but takes up more storage space. For
example TV shows are usually filmed at 24 frames per second however this is
unnecessary for most CCTV Systems. A frame rate of 12 frames per second would
still capture 12 high resolution images every second.
Video Encode Type
The video encoding type is the compression technique used when recording footage
and can be set in the
Video Encode Type drop down list.
H.265 is a clever compression technique that is twice as effective as H.264. This
means you can effectively record at double the quality or for twice as long using the
same storage space.
However, you may wish to record using H.264 encoding if you plan on backing up
footage to watch on a device that doesn't support H.265 encoded video files.
Bitrate Control
The bitrate is simply the amount of data transferred per second so the higher the
bitrate the higher the quality of the image produced.
You have two options to choose from in the Bitrate Control drop down list, VBR or
CBR .
VBR (Variable Bit Rate) - allows the bitrate to change based on the complexity of
the image. This means the bitrate can increase or decrease when needed which
could produce higher quality video however it can take longer to process as there is
more work involved. VBR will use the bitrate set in the Bitrate column as a starting
point and then adjust as required.
CBR (Constant Bit Rate) - allows you to set a specific bitrate used for recording.
Files are easier to process but the recoding is less flexible as the bitrate doesn't
change irrespective of how much or how little action is taking place in the camera's
image. CBR will use the bitrate set in the Bitrate column when capturing images.
