DESCRIPTION, FEATURES, and
DESCRIPTION
The AD1562
is a video motion detection system
for use with one or two cameras surveying indoor or outdoor
scenes. Individual programmable detection zones optimize
motion detection for each camera scene.
Only standard color or black and white video signals
the
cameras are required. No external video sync drives are
necessary. The video inputs are passively looped through the
which allows the motion detector to be turned off
with no loss of video on the line.
Successful operation of video motion detectors depends on
many factors. Review the sections on System Considerations
and Scene Management, in the Appendix, before setup and
operation of the system.
FEATURES
Digital Motion Analysis
A high-speed microprocessor in the
analyzes
detected motion for size, position, and movement to
discriminate against undesired targets and to verify a valid
intrusion before an alarm is issued.
Multiple Alarm Action
Verified intrusions initiate visual and audible alarm signals.
An audible alarm and an on-screen detection trace are provided
in response to motion detection alarms. Video outputs are
available for input to a video switcher, monitor, VCR, or other
video equipment. Separate Form C relay and
logic
outputs provide control for external devices. An alarm
message is also transmitted to a Matrix Switcher. Loss of
video sync from either channel input also triggers an alarm.
Dynamic and Guardian Modes
The
can operate in either Dynamic or Guardian
mode. Dynamic mode provides selection of all detection
characteristics for motion analysis of each video input frame.
Guardian mode sets parameters for comparing the input frames
to a stored, static image for a specified level of change in the
picture content.

Motion Detection Characteristics
The following motion detection characteristics are definable by
the user.
DETECTION ZONES: Each camera video picture is
divided into a number of motion detection cells. These
cells are grouped into patterns called Detection Zones,
within which motion detection is analyzed.
separate
Detection Zone patterns may be defined for each channel.
SENSITIVITY: This characteristic defines the amount of
video change required to initiate detection analysis.
SCENE RETENTION: This characteristic affects the
sensitivity of the unit to slow changes in the scene under
surveillance.
ADJACENCY: This characteristic defines the relative size
of a detected object, in terms of contiguous cells that must
detect motion for an alarm (Dynamic mode only).
ZONE BORDER CROSSED: This characteristic defines
the direction of motion of an object crossing zone borders
that causes an alarm (Dynamic mode only).
On-screen Menu Setup
All characteristics of the
are programmable
through on-screen menus. The menu system is
protected.
INSTALLATION
This installation should be made by qualified service personnel
and should conform to all local codes. Safeguards must be
taken to avoid unintentional operation by employees and
personnel working about the premises, by falling objects, by
customers, by building vibration, and by similar causes.
Mounting
The
is supplied as a desktop unit. Mount in a
convenient location near associated monitors and other video
equipment. For rack mounting, AD21 17 Series rack-mount
kits are available. The
is a half-rack unit.
