• When setting up Dry Contacts on NBN-921-P IVA serials and NBN-498 serials, it is necessary to

activate the Alarm Inputs on the camera GUI first. Users must change the Active dropdown list

value from 'None' to 'N.O.' or 'N.C.' on the camera, as 'None' means disabled and this does not

automatically change when Dry Contacts are activated on the NVR.

• Due to a camera limitation, for Bosch Dinion HD 1080P D/N IVA, if the users sets stream 1

codec H264 and 30 FPS, stream 2 codec H264 then the streams can only reach 10 FPS, due to

stream 2 being dependent on stream 1.

• Handler supports Generic functions including dual stream and audio stream with the following

limitations:

• Cameras need to provide three streams, including two H264 streams and one

MJPEG stream. So the handler can support dual H264 streams or one H264

stream and one MJPEG stream.

• Resolution list includes HD resolution (1080P and 720P) and SD resolution (CIF

and 4CIF), but cameras may only support one or several of them.

• Audio codec G711 can be supported by the audio stream, other codecs are not

supported.

• It is found that different camera firmware versions can return different camera types. This causes

the handler to recognize the camera as Generic camera. Please ensure the Bosch camera has

the recommended firmware version before adding it to the NVR.

• Due to camera limitations on the AutoDome Jr 800 HD, it supports single H264 stream when the

resolution is set to 1080P or 720P 50 (PAL)/60 (NTSC) FPS on H264 stream 1, and H264

stream 2 is only a copy of H264 stream 1 when 1080P is selected for stream 1. It supports dual

H264 streams when resolution and FPS are set to 720P and 25 (PAL)/30 (NTSC) FPS or below,

and H264 stream 2 can be set to 4CIF and CIF resolution.

• Due to camera limitation, when setting 1080P for MJPEG stream on the Autodome Jr 800HD, it

is shows 1920x1072.

Known Issues

• The FPS is only 2.75 when MJPEG streaming (25 fps) is in use. It is a known camera limitation.

Confirmed with Bosch support that for most of the Bosch cameras FPS can only reach up to 5

FPS.

• Audio and video is not synchronized with MJPEG stream on victor client. This is due to the

MJPEG stream limitation on the FPS only reaching a low rate.

• When setting Brightness and Contrast on the NBC-265-P, it returns an error message. This is

because it uses different CGI from other cameras, so these properties and functions are not

supported.

• Frequent Video Loss for Bosch Dinion HD 1080p D/N IVA is caused by the default NVR storage

setting. The recommended mount option when setting up the NVR is:

nofail,noatime,nodiratime,attr2,nobarrier,noquota,allocsize=4M

• Bosch Dinion 1080P frequent video loss during dual stream soaks.Bosch NBN-498-P IVA

frequent video loss.Pause then Play causes Victor to freeze and sometimes crash.



These three defects are due to setting the GOP structure to "IBP" on the camera GUI. It should

be set to "IP".

• When the network connection drops from the NVR to the cameras, then after a while,

reconnected, the device may not work as well. After restarting the camera, it will work as normal.

• Due to an NVR web client known Issue, when Stream 2 is enabled with the same codec as

Stream 1, the setting is a copy of the Stream 1 settings. But Bosch dual H264 stream support

has a different resolution list. So when the client applies, it shows and applies a different

1 2 ... 72 73 74 75 76 77 78 79 80 81 82 ... 107 108
