accurate update files;

Image preview or playback abnormal, 4 kinds of ordinary situations as below,
1
st
, IP Camera IP address can be searched, multi-images sub stream and single image main
stream all cannot have image;
2
nd
, Single image main stream has image, multi-images sub stream is on black screen;
3
rd
, Multi-images sub stream has image, single image main stream is on black screen or still image
as well as black-screen playback;
4
th
, image or screen crashes
To choose mode is very important when NVR can be access to different brand and different
resolution IPC.
Above 4 kinds of malfunctions are very common in real utilization and this is all following the steps:
Setting→Device→Device info→Stream type.
The first 3 numerical values must be matched with IPC’s stream setting. IPC’s main stream, sub
stream and reference frame must be equal to or less than the numerical values of NVR’s stream
type. Stream type adjustment need to be saved and restart to make it effect.
The first numerical value of stream type “main” represents the IPC accessible channel numbers
and main stream resolution ratio; The second one “sub” is subs stream’s resolution ratio; The third
one “ref” is the reference frame IPC can get access to; The fourth one “play” is the playback
channel numbers under this kind of stream type.
Solution of 1
st
situation which IP address can be searched but without any images:
1
）
Adjustment of stream type, choose stream type with ref value for 4ref. To get access to
Ambarella solution IPC needs 4ref;
2
）
IPC’s username and password should be correctly filled in;
3
）
This IPC has not been butt joint or version outdated, which needs supplier’s confirmation for
butt joint and then update NVR firmware.
Solution of 2
nd
situation which single image main stream has image and multi-images sub stream
is on black screen:
1
）
Adjustment of stream type, choose stream type with sub stream of 720×576, please be aware
if main stream resolution ratio and IPC’s are matched;
2
）
By IPC’s IE(IPC IP address access) or PC Client, users need to adjust IPC’s sub stream for
resolution ratio of VGA or CIF;
3
）
To update NVR firmware.
Solution of 3
rd
situation which multi-images sub stream has image and single image main stream is
on black screen or still image as well as black-screen playback:
1
）
Adjustment of stream type to 1080P mode;
2
）
By IPC’s IE(IPC IP address access) or PC Client, users need to adjust IPC’s main stream with
resolution ratio for 960P or 720P;
Solution of 4
th
situation which image is crashed is same as 3
rd
situation; If the whole screen is
crashed, it may be connected with NVR hardware malfunction or lunk. Please check if monitor
resolution ratio is matched or exchange of another monitor and lunk.
