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-by-pixel 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 tri-streaming 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 constrainedbandwidth 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,
self-contained 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.
Access Security
Various security levels are available for accessing the
network, the camera, and the data channels. As well
as password protection with three levels, 802.1x
authentication using a RADIUS is supported. To secure
Web browser access use HTTPS with a SSL certificate
stored in the camera. For total data protection, the
video and audio communication channels can be
independently AES encrypted with 128‑bit keys by
installing the optional Encryption Site License.
