The Bosch Video Recorder 400 Series is a 4 channel digital
recorder that uses the latest H.264 compression
technology. With a built-in web server for browser-based
video management, the 400 Series is a fully integrated,
stand-alone video solution that's ready to go, straight out of
the box.
Available in basic and advanced versions, the 400 Series
features a highly reliable embedded design that minimizes
maintenance and operational costs. The basic version
provides one audio input, while the advanced version has
four audio inputs and a DVD writer.
System Overview
The Bosch 400 Series takes advantage of the latest H.264
compression technology that allows for more efficient video
compression. This reduces the amount of storage and
bandwidth needed while also producing better image
quality. The 400 Series records multiple video and audio
signals while simultaneously providing live multi-screen
viewing and playback. Comprehensive search and playback
functions provide quick recall and viewing of recorded
video.
Recording
Ease of use is key to the 400 Series design. Simply connect
the cameras, apply power, and the unit begins recording
automatically. All recording takes place in the background
with no operator intervention required.
The use of H.264 compression reduces the file size of
recordings by as much as 30% compared to standard
MPEG-4, without sacrificing image quality. The Bosch Video
Recorder 400 Series can record at up to 25 (PAL) /
30 (NTSC) images per second, per channel at CIF
resolution. Recording at 2CIF and 4CIF resolution is also
possible by reducing the recording image rate settings. The
recording rate and quality are individually configurable per
channel for maximum flexibility.
The recording archives are split into two partitions. Alarm
recordings (input and motion) are stored on one partition,
while continuous recordings are stored on a separate one.
An overwrite mode can be selected separately for each
partition if required.
Dome Control
The 400 Series can control pan/tilt/zoom (PTZ) equipment
via RS‑232 and RS‑485 serial communications. PTZ devices,
including the Bosch AutoDome Modular and AutoDome
Easy II, are supported.

Alarms
All models have extensive alarm handling functions and
telemetry control. Alarm functions include motion detection
in user-definable areas of the image on any camera input.
Local control and operation
The unit can be easily operated and programmed via the onscreen display menu system using either the front panel
control keys, the mouse, or the remote control. Two
monitor outputs provide full-screen, quad (main monitor
only), and sequenced viewing.
Looping auto-terminating video inputs and outputs, audio
inputs and output, and alarm inputs and outputs are located
on the rear panel. The VGA connector provides an output
for monitor A (main monitor). A CVBS video output is also
provided for monitor B (spot monitor). Monitor A displays
live and playback in full-screen or quad digital pictures that
can be frozen and zoomed. Monitor B displays live fullscreen pictures.
Remote control and operation
Use the built-in web application via a network for live
viewing, playback, and configuration; there is no need to
install any additional software for viewing. Four users can
control the Bosch 400 Series simultaneously.
The Bosch 400 Series includes an authenticity check for
both local and remote playback, ensuring recording
integrity. The Bosch 400 Series Archive Player is provided
for playback of secure video files.
