Video | VOT‑320 Thermal IP Camera

The VOT‑320 thermal IP camera provides high sensitivity,
uncooled long wave thermal images. It can tri-stream
video simultaneously on two H.264 streams and one JPEG
stream. The camera uses a Vanadium Oxide (VOx) focal
plane array with an image resolution of 320x240 pixels
that delivers outstanding image quality and sensitivity. It
offers a choice of various lenses—both narrow field of view
(NFOV) and wide field of view (WFOV)—and is available
with a frame rate of 8.33 or 30 Hz.

VOT‑320 is designed to combine the benefits of thermal
imaging with the well-proven Bosch IVA features. Thus a
unique product was created that offers early detection
and display of irregularities over large areas even with
poor visibility or absolute darkness. Neither dense smoke
nor bad weather conditions as heavy fog or snow affect
visibility. With a VOT‑320 there is no need for natural or
artificial lighting of the area of interest.

Focused on heat radiating objects, crisp images are
generated that are not constricted by shadows or similar
effects as regular video images are. The VOT‑320 camera
uses advanced video processing technology for pixel-by­pixel analysis. This provides the user with the most
detailed information of the scene.

Enclosed in a robust outdoor housing with integrated
window heater, VOT‑320 is ideal for a wide range of
applications like fire defense in power plants, coast line
monitoring, and traffic control in tunnels.

Features such as multicast, internet streaming, and
iSCSI recording are fully supported. The VOT‑320 camera
is designed on the state-of-the-art Bosch IP platform
which conforms to the highest standards of performance
and reliability in any security and surveillance scenario.

Functions

Outstanding Image Quality

With its 320x240 VOx sensor, the VOT‑320 IP camera
delivers outstanding image quality. The Bosch designed
digital video processing system optimally handles the
thermal image format without compromise. Temperature
differences of 50 mK or less are made visible. Video
processing features include multiple automatic, dynamic
image optimization algorithms, as well as polarity control
(white hot/black hot). Automatic flat-field correction
(FFC) updates correction coefficients of the camera,
resulting in a more uniform array output.

Efficient Bandwidth and Storage Management

The cameras use H.264 compression, bandwidth
throttling, and multicast capabilities to manage bandwidth
and storage requirements efficiently, while delivering high
image quality and resolution. Bosch's innovative tri­streaming feature enables VOT‑320 IP cameras to
generate two independent H.264 streams and one
JPEG stream simultaneously. This allows the streaming of
one high-resolution H.264 stream for live viewing and
recording, and a second lower resolution H.264 stream for

constrained-bandwidth networks. The JPEG images can
be streamed to another device at the same time. The
JPEG video stream also provides easy integration with
third-party JPEG compatible video management systems.

Recording Options

VOT‑320 cameras offer unparalleled recording options.
Attached to the network, they can use iSCSI targets
directly. The iSCSI storage target support enables the
cameras to function as a conventional DVR, while
streaming high-performance live video across the network.
The VOT‑320 cameras also provide the user with a local
storage option within the camera.

Users can record the streams independently on different
media. Thus video can be recorded centrally on iSCSI
drives managed by VRM Video Recording Manager and
redundantly on the local SD card. If necessary (for
example, in case of a network failure), VRM can fill the
gap in the central recording using Automatic Network
Replenishment (ANR).

When used with a SD card, the camera is a complete, self­contained surveillance system without the need for
additional equipment.

ONVIF Conformance

The camera conforms to the ONVIF (Open Network Video
Interface Forum) specification which guarantees
interoperability between network video products
regardless of manufacturer. ONVIF conformant devices are
able to exchange live video, audio, metadata and control
information. They are automatically discovered and
connected to network applications such as video
management systems.

Unsurpassed Flexibility

There are many ways to access the camera’s video: on a
PC using a web browser, with the Bosch Video
Management System, or with the supplied Bosch Video
Client.

Bosch Video Client Surveillance Software

The bundled Bosch Video Client PC surveillance software
offers a user-friendly interface to support easy installation
and configuration. A wizard allows the configuration of
multiple cameras simultaneously using an auto detection
device. Multiple cameras can be monitored in one screen
and video clips on the SD card can be archived and
searched in a single application.

Bosch Video Client supports up to 16 cameras without
licensing and can be expanded to up to 64 cameras by
adding 8- or 16‑channel licenses.

Easy Upgrade

Remotely upgrade the camera whenever new firmware
becomes available. This ensures up-to-date products, thus
protecting investment with little effort.
