Bosch Video Management System

Recording Settings

Technical Note

1 Overview

The basic settings (non-scheduled) have been separated from recording settings (scheduled). Basic settings are for the initial configuration of streams. Recording settings are for assigning these streams to different use-cases, such as continuous recording, pre-alarm recording, or alarm recording. The recording settings are arranged in a new dialog called Scheduled Recording Settings, accessible via the Cameras and Recording page. For more details, see Changing qualities in schedules, page 10.

Use cases for multi system access

Two Bosch VMS features valid for multi system environments are available: Enterprise System and Server Lookup.

An operator might want to access a multi system environment for the following reasons:

3 Basic stream settings (schedule-independent)

You can configure different codec profiles in the Camera and Recording page of the Configuration Client.

3.1 Codecs and HD resolution

Codecs are part of the basic stream settings. The Bosch VMS gives you default settings for all codecs and qualities. You can change these settings to your own configuration.

It depends on the camera device family which codec you can select. See the list below for detailed information per device family.

Device family Description
VIP X 1600 XFM4 You can configure H.264 BP+ (Baseline Profile+) and H.264 MP (Main Profile). By default, H.264 MP is configured for both streams 1 and 2. We recommend not changing these settings.
Note: The H.264 BP+ codec for XFM4 is limited to 2500 kbps.
For VIP X 1600 XFM4 devices specific H.264 codec functions are available in the Stream Quality Settings dialog box.
You can enable or disable H.264 deblocking filter and CABAC (Context-based Adaptive Binary Arithmetic Coding) individually for each stream quality. If many Image panes are required to display in Operator Client, resolve performance issues by disabling CABAC and H.264 deblocking filter.
The MPEG-4 SH++ codec profile is available. H.264 Baseline Profile (BP) is not supported in Bosch VMS for VIP X platform devices.
Device Family 1 The MPEG-4 SH++ codec profile is available. H.264 Baseline Profile (BP) is not supported in Bosch VMS for VIP X platform devices.
Device Family 2 For an ARM SD device, select a pre-defined H.264 codec profile (H. 264 MP Low Latency). You can configure H.264 MP Low Latency and H.264 BP+. By default, H.264 MP Low Latency is configured for both streams 1 and 2. We recommend using this setting.
Note: The H.264 BP+ codec for ARM SD devices is limited to 1200 kbps.
Note: For displaying live video on a VIPX Decoder, select H.264 BP+ due to hardware limitations of the decoder. It is only possible to use H.264 BP+ on one stream. If H.264 MP is selected, live video on a decoder is not possible.
Device Family 3 As the codec for HD is always H.264, the HD resolutions 720p and 1080p are fixed with the codec configuration. Stream 1 is the main HD stream. You can copy stream 1 and generate a second HD stream with the same settings. Bosch HD devices are able to generate an independent second stream in SD resolution with different settings to stream 1. To generate an SD stream in SD resolution for an HD device, limit the performance of stream 1 (see device's data sheet). Configure the stream quality settings in the stream quality dialog.

Stream assignment for Live Video

You can assign either stream 1 or stream 2 for Live Video. The quality and codec of the basic stream settings are used.

Stream 1 Codec Stream 1 Quality Stream 2 Codec Stream 2 Quality Live Video Stream Live Video Profile Device Family Recording Setting
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm
H.264 MP 1080p25/30 fixed HD Quality (1080p) Copy from Stream 1 Quality of Stream 2 Stream 2 Device Family 3 Continuous, Alarm
H.264 MP 1080p25/30 fixed HD Quality (1080p) Copy from Stream 1 Quality of Stream 2 Stream 2 Device Family 3 Continuous, Alarm
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm
H.264 MP (Low Latency, SD) Good H.264 MP (Low Latency) Good Stream 2 Device Family 2 Continuous, Alarm
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm
MPEG-4 SH++ Normal MPEG-4 SH++ Good Stream 2 Device Family 1 Continuous, Alarm

5 Scheduled Recording Settings

To display the Scheduled Recording Settings dialog box, click Edit scheduled recording settings in the toolbar of the Cameras and Recording page.

Cameras are typically grouped by location and/or schedule (e.g. Alarm Recording Night and Weekend), and not by technical differences between camera models.

You can map these groups as templates in the Scheduled Recording Settings dialog. You perform all recording configurations in this dialog box.

Continuous, Alarm Recording is the default setting for a camera that is added to Bosch VMS.

The following dialog box illustrates the Scheduled Recording Settings:

Dialog Description: The dialog box titled 'Scheduled Recording Settings' allows users to configure recording settings. It includes fields for 'Name' (e.g., 'Alarm Recording'), 'Device Family' selection, and 'Recording Settings' with options for 'Day', 'Night', and 'Weekend'. Under 'Continuous or Pre-alarm Recording', users can set 'Recording Mode' (Continuous, Prealarm), 'Stream', 'Quality', and 'Duration'. For 'Alarm Recording', options for 'Alarm Recording', 'Motion Alarm', 'Stream', 'Quality', and 'Duration (Post-alarm)' are available. Users can enable or disable these settings and click 'OK' to save or 'Cancel' to exit.

The table below shows the recording settings for different device families and schedules:

Recording Settings Device Family 1 Device Family 2 Device Family 3
Recording On / Off (setting valid for all device families)

Duration (post-alarm) 5s - 3h 5s - 3h 5s - 3h

You should give your configuration a descriptive name which is then displayed in the Available Recording Settings list.

You can select all configured recording settings in the cameras list. Assign one recording setting per camera. You can copy and paste one setting to all cameras for fast configuration.

5.1 Changing qualities in schedules

You can configure stream qualities per recording schedule. Depending on the encoder/camera devices, you can modify the quality properties.

The following table details stream quality modifications:

Device Family 1 Device Family 2 and 3
Streams You can change recording qualities (incl. resolution change) for example for alarm recording. You can modify the existing stream with the settings of another stream quality. But only Image encoding interval and Target bit rate are modified. Other settings like the resolution are not modified.
Notes For the XFM4 platform possible recording gaps can be up to 4 frames, 133/160ms (NTSC/PAL) on alarm recording and schedule change if active recording quality differs. Possible recording gaps can be up to 12 frames, with 1 IPS up to 12 seconds on schedule change if active recording quality differs from old to new schedule.
Examples Stream 2 is selected for normal recording and configured with Normal quality. For an alarm the Excellent quality is selected. When an alarm occurs, all settings of the Normal quality are used except Image encoding interval and Target bit rate which are modified with the values of Excellent.
