| Intelligent Video Motion Detection into its Range of IP Network Video Products

o More efficient use of bandwidth and storage o More reliable CCTV surveillance
and alarm handling with reduced human involvement o Lower running
expenses
Bosch Security Systems is introducing new Intelligent Video
Motion Detection (IVMD) into its IP network video products to significantly
increase the possibilities for fully-automated CCTV surveillance and to reduce
demands on bandwidth and storage capacity.
Transmission and storage of
continuous video streams during CCTV surveillance puts considerable strain on
both bandwidth and storage capacity as well as on the security personnel who
have to monitor scenes in which, for the majority of the time, nothing happens.
By introducing a more event-based surveillance regime, IVMD ensures that only
scenes in which important changes occur are captured, transmitted and stored.
Utilizing the increased processing power and intelligence inherent in today's IP
network video products, Bosch's IVMD essentially makes a series of basic
pre-decisions governing scene capture based on parameters set by the user during
system configuration.
Bosch's current IP network video products based on
firmware release 1.5, which comprises the VIP X1, VIP X2 and Dinion IP cameras,
already include sophisticated motion and tamper detection as standard functions.
From end May 2006, these products will be supplied with firmware version 2.0
which will also include a licensable option to enable IVMD. All newly introduced
products, like the VIP X1600, also support IVMD.
The IVMD function
includes an advanced background learning algorithm developed by Bosch's own
research group that saves computational power by suppressing unwanted
notification from, for example, moving trees, branches, leaves, clouds, shadows
and falling rain and snow. The algorithm is also capable of adapting to changes
in background. Alarms are triggered only in real alarm situations, the
parameters of which are set by the user.
Up to 16 independent detector
fields can be set up for alarm generation. These can be freely arranged over the
video image as polygons with up to 16 vertices. Even completely overlapping or
identical shapes with different trigger parameters can be set. Moreover, alarm
parameters such as size, speed and direction discrimination can be set up
independently for each of the detector fields. With this function a single
camera can, for example, monitor the individual activity through several doors
in a hallway whilst suppressing general activity within the hallway itself.
The IVMD function also features camera calibration for metric or
imperial measurements. This is done via a graphical user interface using a 3D
grid to allow objects to be distinguished by their real size, including the
addition of perspective relations necessary for reliable size and speed
discrimination in all directions. With this function, it is possible to trigger
alarms only on objects below or above a specified size, for example just for
trucks or cyclists. Or to trigger alarms just for objects travelling below a
specified speed, say pedestrians walking on a highway.
Owners of Bosch's
current IP network video products will also be able to benefit from IVMD
functionality by upgrading their products' firmware to version 2.0 (which is
freely downloadable from the Bosch web site) and purchasing a license to
activate the new functionality.
