Hybrid NVR User Manual
69
Bitrate Type:
Set the bitrate type to be Variable or Constant.
Video Quality
: Set the video quality of recording, with 6 levels configurable.
The Stream Type, Resolution, Bitrate Type and Video Quality are not configurable for the Main
Stream (Event) of the IP Camera.
Frame Rate:
Set the frame rate of recording.
For LTN87XXK-HT series NVR, when 5 MP signal input is connected, the frame rate of the
main stream cannot exceed 12 fps. When 4 MP signal input is connected, the frame rate of
the main stream cannot exceed 15 fps.
LTN8708K-HT/ LTN8716K-HT cannot exceed 8 fps, When 8 MP signal input is connected.
Max. Bitrate Mode:
Set the mode to General or Custom.
Max Bitrate (Kbps):
Select or customize the maximum bit rate for recording.
Max. Bitrate Range Recommended:
A recommended max. bit rate range is provided for
reference.
Max. Average Bitrate (Kbps):
Set the max. average bit rate which refers to the average
amount of data transferred per unit of time.
Video Encoding:
You can configure H.264 or H.265 for the main stream (continuous) of IP and analog
cameras.
When the connected IP camera does not support H.265, only H.264 can be seleted for the main
stream (continuous).
Step 3
Check the checkbox of
Enable H.264 ZIP+
or
Enable H.265+
to enable this function.
Enabling it helps to ensure the high video quality with a lowered bitrate.
For –K series NVR, the analog and IP cameras support enabling H.264 ZIP+/H.265+ if the
video encoding is H.264/H.265 for the main stream.
After enabling H.264 ZIP+ or H.265+, the
Bitrate Type
,
Video Quality
,
Max. Bitrate Mode
,
Max. Bitrate(Kbps)
and
Max. Bitrate Range Recommend
are not configurable.
If H.265+ is enabled, line crossing detection and region entrance detection are not
supported.
For the connnected IP camera, the H.264 ZIP+ or H.265+ should be supported by the
camera and added to the NVR with the protocol.
