4.0 Brief Description
DMD-4 is a digital video sensor for simultaneous monitoring of four camera signals
(channels) for indoor and outdoor applications.
The sensor is also capable of detecting video picture changes under difficult light
conditions.
The PC setup program interface of the DMD-4 allows comfortable setting of all sen-
sor parameters.
First, the respective camera picture has to be transmitted from DMD-4 to the PC
and displayed in an editor window. Each channel can be configured for four time
zones. Using the PCs mouse you can now define four sensor areas per channel ac-
cording to the local conditions.
For each sensor area there are extensive setting possibilities such as number of
sensor cells, sensitivity, perspective, reset timer or alarm strings.
For recognition of sabotage events like spraying or other manipulations you can ad-
just a special sabotage analysis.
In case of a detected object the sensor can control a dome camera regarding to the
centre of gravity („Dome tracking‟). You can choose a protocol from a list of many
well known manufactures.
Having programmed all setup-parameters, these are transferred from the PC to the
DMD-4. The sensor now operates with the new parameters independently from the
PC.
The setup data can also be stored on hard disk/diskette. Thus it is possible to trans-
fer standardized settings without great effort to several sensors. In case of failure,
the service engineer can determine whether the setup has been changed by unau-
thorized persons and he can directly reestablish the original configuration.
The camera pictures including the defined sensor areas can be stored in graphic
format (*.jpg or *.bmp) for documentation purposes.
DMD-4 uses state-of-the-art Flash technology:
Upgrading the operating software (firmware) can be performed without opening the
equipment; upgrades can be loaded via PC or laptop via the RS232 interface.
In the following sections the setup functions, the individual sensor parameters and
their settings are briefly described. The diagram on the following page shows an
overview of the parameters that can be configured in the menu.
