DESCRIPTION, FEATURES, and

INmALLATION

DESCRIPTION

The AD1562

DnoTect-C

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 from the

cameras are required. No external video sync drives are

necessary. The video inputs are passively looped through the

DuoTect-C, 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

DuoTect-C

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

T&level

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

DuoTect-C

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. Three 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

DuoTect-C

are programmable

through on-screen menus. The menu system is

passcode

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

DuoTect-C

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 DuoTect-C is a half-rack unit.

General Menu Procedures

When any menu is displayed, one line or section is blinking,

indicating the menu cursor. The cursor blinks on the setup

function that can be selected or changed. Use the front panel

UP or DOWN buttons to move the cursor to the desired menu

line. When the desired function is blinking, press the MENU

button to advance to that menu or function.

All menu parameters are set in the same way: position the

cursor to the parameter name with the UP/DOWN buttons,

then change the value with the LEFT/RIGHT buttons.

When the desired changes have been made to the parameters,

press the ALARM button to save the displayed values and exit

the menu system. In Guardian mode, this action also saves the

current input video image to be used in the Guardian

comparison function.

Current Mode

Dynamic or Guardian

The

DuoTect-C

can operate in either Dynamic or Guardian

mode. Dynamic mode provides selection of all parameters for

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.

Both channels of the

DuoTect-C

are set to the same mode.

The selected mode is shown in the CURRENT

MODE line of

the Main Menu. The default mode is Dynamic. The current

mode may be changed via the Set System Parameters setup

function, page 7.

Motion Detection Parameters

Motion detection in the

DuoTect-C

is controlled by setting

several parameters which establish the criteria for detected

motion in each video channel. These parameters, listed above,

are used in different combinations depending on the current

mode, Dynamic or Guardian.

The following paragraphs define the motion detection

parameters. The pages identified in the above table describe

the setup procedures for these parameters.

Detection

A video picture input to the AD1562 is divided into detection

cells within which motion can be detected. (There are 896

cells in the AD1562

NTSCIRS-170

model and 1024 cells in

the

AD1562X

CCIRPAL

model.) These detection cells can

be grouped by the user into patterns called Detection Zones

that cover areas of the video picture. Three separate Detection

Zones can be defined for each channel, with different motion

detection characteristics set for each zone. To provide

optimum motion detection for individual camera scenes, the

pattern (size and shape) of each Detection Zone should be

adjusted for the areas being viewed.

The Scene Retention parameter affects the unit’s sensitivity to

slow changes in the scene under surveillance, such as changes

due to the movement of the Sun and its shadows. The range of

settings for Scene Retention is from 1 to 15, where 1 is

maximum retention and 15 is minimum retention. High

settings result in higher sensitivity to slow or infrequent

motion, such as the movement of leaves on a tree. Low

settings result in decreased sensitivity to such movements.

Scene Retention is set in conjunction with Sensitivity, below.

Sensitivitv

The Sensitivity parameter adjusts the motion detection

circuitry of each channel to detect moving objects of varying

speed and contrast. The range of settings for Sensitivity is

from 1 to 15, where 1 is the lowest sensitivity and 15 is the

highest sensitivity. High settings of Sensitivity result in

detection of slow moving objects with very low contrast, while

low settings require greater contrast or speed to cause an

alarm.

The Adjacency parameters specify the number of adjacent cells

that must detect motion in the same video frame. Low settings

of Adjacency result in the unit being more sensitive to smaller

objects. Adjacency is set separately for both horizontal and

vertical movement; an alarm is initiated if adjacent movement

occurs in either direction. The setting range is from 1 to 7

where 1 is minimum (no) adjacency, and 7 is maximum

adjacency (seven adjacent cells must detect motion). If either

direction is set to

there is no adjacency in both directions.

7me

1.2.

and

The Zone Enabled parameters determine if each Detection

Zone is enabled for standard motion detection. Zone Enabled

is set to either YES or NO for each detection zone. If set to

YES, any motion detected within that zone, in accordance with

the prior detection parameters, initiates an alarm. If set to NO,

standard motion detection is not enabled for that zone. If

either Zone 1 or Zone 2 are set to YES, both Zone Crossed

detection parameters, below, are reset to NO.

l-2

Cross&.&

Zone 2-l Crossed

This parameter establishes a direction of motion detection

between zones 1 and 2 for each channel. If “ZONE 1-2

CROSSED” is set to YES, an alarm is activated only if motion

is detected crossing from Zone 1 to Zone 2. The “ZONE 2-l

CROSSED” parameter establishes this criteria in the opposite

direction; if set to YES, there must be motion crossing from

Zone 2 to Zone 1. These parameters are exclusive; if one is set

to YES, the other is reset to NO. Also, if either Zone Border

Crossed parameter is set to YES, both the Zone 1 and Zone 2

Enabled parameters, above, are reset to NO.

View Obstruction

The View Obstruction parameter defines the relative amount of

change in picture content, as compared with a pre-stored

image, which is required for an alarm. There are three settings

for View Obstruction. The LOW setting results in a motion

detection alarm when there is over 50% change in the picture

content from the stored image. The MED setting results in

motion detection when there is over 75% change, and the

HIGH setting results in motion detection only when there is

over 87.5% change in the picture.

SETUP

Alarm Operation Parameters

The following paragraphs describe several parameters which

control the

DuoTect-C

response to detected alarms. The

channel setup menus, pages 10 and 12, provide procedures to

set these parameters in either of the setup modes.

Beeaer

The audio beeper provides an audible alarm when a motion

detection alarm is activated. The beeper is enabled or disabled

separately for each video channel. When alarms are enabled

and valid motion is detected in a cell, the audible alarm

indication sounds if it is enabled (ON).

When a loss of video is detected on a channel, the audio beeper

sounds intermittently. The beeper sounds even if it is disabled

(OFF) by the setup menus.

Detection Trace

Detection Trace is used to identify and follow detected motion

in Dynamic mode. When motion is detected in a cell, a white

dot is displayed in that cell. When motion is no longer

detected, the intensity of the dot gradually fades, through eight

levels of intensity, until the dot is the same level of intensity as

the input video. The rate at which the intensity fades is set

with the Trace Fade Rate parameter, page 7. When another

cell detects motion, this process repeats. This gives the

appearance of following the detected motion on the screen.

Detection indicator

In Guardian mode, when the current image in a zone changes

by a specified amount (View Obstruction setting, page

5),

the

entire Detection Zone is filled with white dots in each cell.

The dots do not vary in intensity; they are removed when the

change in the image drops below the specified amount.

Alarm Mode

When valid motion is detected by the DuoTect-C, audible and

visible alarm indications are activated. The Alarm Mode

parameter of each channel determines the method of clearing

the alarms. The are three Alarm Mode clearance methods:

Instant (INS)

When motion is no longer detected in any

cell, the alarm automatically clears.

Auto

(AUTO)

When motion is no longer detected, and after

a 20 second delay, the alarm clears. This 20 second delay is

intended to catch any momentary type alarms.

Manual Acknowledge (MAN)

The operator controls the

clearance of an alarm by pressing the ALARM button.

See Operation, page 17, for a further description of the Alarm

Clearance procedures for each of these modes.

Alarm codes are transmitted by the

DuoTect-C

to a Matrix

Switcher/Controller via the RS-232 Output port (page 2). For

alarm processing in the Matrix Switcher/Controller, each video

channel must be assigned an Alarm Contact Number

(ACN).

The ACN range is from 1 to 1024 (the maximum ACN may be

less for certain Matrix Switcher/Controller systems).

To provide a valid ACN in the transmitted alarm codes, two

parameters must be established via the setup menus: AD

Contact Group and AD Contact Number.

The AD Contact Group specifies the range of ACN’s that

may be assigned to either channel’s alarm codes. There are

16 Groups, A through P. The AD Contact Group is set via

the Set System Parameters menu, page 7. The same value

is set for both video channels.

The AD Contact Number specifies the relative Alarm

SETUP

Setting Channel Dynamic Attributes

Setting channel Dynamic attributes is the second setup

procedure of the Dynamic mode setup. A Channel Setup menu

for Dynamic attributes is displayed following completion of

the Configure Detection Zones setup procedures (page 9).

This menu, illustrated below, is used to set the motion

detection criteria for the selected channel. The system default

values are indicated in this menu illustration.

Three separate parameters are used to control motion detection

in Dynamic mode for each Detection Zone in a channel:

SCENE RETENTION, SENSITIVITY, and ADJACENCY.

These parameters together determine the movement detection

characteristics of each zone. An alarm is activated when

detected movement meets the criteria set for all three

parameters.

Note:

After adjusting any of these parameters, it is essential to

test each channel and zone to verify the settings.

SCENE RETENTION

The SCENE RETENTION parameter affects the unit’s

sensitivity to slow changes in the scene under surveillance,

such as changes due to the movement of the Sun and its

shadows. High settings result in higher sensitivity to slow or

infrequent motion, such as the movement of leaves on a tree.

Low settings result in decreased sensitivity to such

movements. Retention is set the same for all zones in each

channel.

The setting range for SCENE RETENTION is from 1 to 15

where 1 is maximum retention, and 15 is minimum retention.

The default setting for SCENE RETENTION is 8. To change

the setting for the selected channel:

Move the cursor to the SCENE! RETENTION line.

2. Press the LEFT or RIGHT button to decrement or

increment the value, from 1 to 15.

SENSITIVITY

The SENSITIVITY parameter adjusts

the

motion

detection

circuitry of each channel to detect moving objects of varying

speed and contrast. High settings of Sensitivity result in

detection of slow moving objects with very low contrast, while

low settings require greater contrast or speed to cause an

alarm. Sensitivity is set separately for each zone in the

selected channel.

The setting range for SENSITIVITY is from 1 to 15, where 1

is the lowest sensitivity and 15 is the highest sensitivity. The

default SENSITIVITY setting for each zone is 8. To change

the setting for each zone:

1. Move the cursor to the SENSITlVITY line for the desired

zone.

2. Press the LEFT or RIGHT button to decrement or

increment the value, from 1 to 15.

Repeat the above steps to set the SENSITIVITY parameters

for each Detection Zone.

ADJACENCY

The ADJACENCY parameters specify the number of adjacent

cells which must detect motion in the same video frame. Low

settings of Adjacency result in the unit being more sensitive to

smaller objects. Adjacency is set separately for both horizontal

(HOR) and vertical (VERT) motion, and for each zone in the

selected channel. An alarm is initiated if adjacent movement

occurs in either direction. An example scenario using

Adjacency is shown in the Appendix, page F.

The setting range for ADJACENCY is from 1 to 7 where 1 is

no adjacency (any motion within a single cell is an alarm

condition), and 7 is maximum adjacency. If either direction is

set to 1, there is no adjacency in both directions.

The default ADJACENCY setting is three cells for both

horizontal and vertical motion. To change the setting:

1. Move the cursor to the ADJACENCY line for either

horizontal (HOR) or vertical

(VERT),

for the desired

zone.

2. Press the LEFT or RIGHT button to decrement or

increment the value, from 1 to 7.

Repeat the above steps to set the ADJACENCY parameters for

both horizontal and vertical for each Detection Zone.

must be detected in the first zone, and then be detected in the

second zone immediately after motion stops in the first zone.

If motion exists simultaneously in both zones, border crossing

is not detected. The minimum size of each zone is four

adjacent cells in the direction of motion.

These parameters are mutually exclusive, only one can be set

to enabled (YES). If either is set to YES, both ZONE 1 or 2

ENABLED parameters are reset to NO. The default setting of

each ZONE CROSSED parameter is NO, border crossing

AUT:

Guardian mode comparison of input frames to the stored image

is controlled by three parameters: VIEW OBSTRUCTION,

SCENE RETENTION, and SENSITIVITY. These parameters

work together to detect a level of change in the input image.

To initiate a motion detection alarm, all three criteria must be

met.

An example scenario using Guardian mode is shown in the

Appendix, page E.

VIEW OBSTRUCTION

The VIEW OBSTRUCTION parameter defines the relative

amount of change in picture content, as compared with a pre-

stored image, which is required for an alarm. There are three

settings for VIEW OBSTRUCTION LOW results in a motion

detection alarm when there is over 50% change in the picture

content from the stored image; MED results in motion

detection when there is over 75% change; and HIGH results in

motion detection only when there is over 87.5% change in the

picture.

VIEW OBSTRUCTION is set to the same value for all zones

in each channel. The default setting is LOW. To change the

setting for the selected channel:

1. Move the cursor to the VIEW OBSTRUCTION line.

2. Press the LEFT or RIGHT button to cycle the value,

between LOW, MED, or HIGH.

SCENE RETENTION

The SCENE RETENTION parameter in Guardian mode

affects the unit’s sensitivity to slow moving objects. High

settings result in higher sensitivity to slow or infrequent

motion, such as the movement of leaves on a tree. Low

settings result in decreased sensitivity to such movements.

SCENE RETENTION is set the same for all zones in each

channel. The setting range for SCENE RETENTION is from 1

to 15 where 1 is maximum retention, and 15 is minimum

retention. The default setting for SCENE RETENTION is 8.

To change the setting for the selected channel:

1. Move the cursor to the SCENE RETENTION line.

2. Press the LEFT or RIGHT button to decrement or

increment the value, from 1 to 15.

SENSITIVITY

The SENSITIVITY parameter adjusts the motion detection

circuitry of each channel to detect moving objects of varying

speed and contrast. High settings of SENSITIVITY result in

detection of slow moving objects with very low contrast, while

low settings require greater contrast or speed to cause an

alarm.

SENSITIVITY is set separately for each zone in the selected

channel. The setting range for SENSITIVITY is from 1, the

lowest sensitivity, to 15, the highest sensitivity. The default

setting for each zone is 8. To change the setting:

1. Move the cursor to the SENSITIVITY ZONE line desired.

2. Press the LEFT or RIGHT button to decrement or

increment the value, from 1 to 15.

DETECT INDICATOR

DETECT INDICATOR places white dots in all cells of the

entire Detection Zone when the current image in a zone has

changed by the specified (View Obstruction) amount. The

dots do not vary in intensity; they are removed when the

change in the image drops below the specified amount.

The DETECT INDICATOR parameter can be set to ON

(enabled) or OFF (disabled). The default setting is ON,

enabled. To change the setting:

1. Move the cursor to the DETECT INDICATOR line.

2. Press the LEFT or RIGHT button to select ON or OFF.
