The Technology ......................................... 2-22-1
Architecture ...................................................... 2-2
Software Architecture ....................................... 2-3
Trigger NG is based on a proprietary and robust video analytics technology for
object detection, tracking and event identification. Trigger NG is capable of
processing video smartly and independently near the camera, thereby increasing
detection accuracy and fault tolerance while reducing network bandwidth and
overall operation costs. An unlimited number of Trigger NG units can be managed
by the Cortex Video Management System.
The description in this user guide focuses on a single Trigger NG Video Detection
Unit (VDU) and the Cortex software as it pertains to configuring Trigger NG.
Trigger NG is currently available in 5 licensing modes:
Trigger NG: analyzes up to 2 video channels concurrently, up to 5 rules per
channel, and supplies an analog output with an overlay of analytic alerts. The
analog output can display the 2 channels side by side or switch between the
channels upon event.
Trigger NG 2S: analyzes up to 2 video channels concurrently, up to 2 rules
per channel, with streaming at 4CIF quality at 7 fps, or CIF quality at full-
frame rate.
Trigger NG 1S: analyzes 1 video channel, up to 2 rules, with streaming at
4CIF quality at full-frame rate.
Trigger NG 1A: analyzes 1 video channel, up to 2 rules, with streaming at
4CIF quality at minimal frame rate (2 fps) and supplies an analog output with
an overlay of analytic alerts.
Trigger NG 2A: analyzes 2 video channels, up to 2 rules per channel, with
streaming at 4CIF quality at minimal frame rate (2 fps) and supplies an analog
output with an overlay of analytic alerts. The analog output can display the 2
channels side by side or switch between the channels upon event.
NOTE:
All Trigger NGs support both analog and IP video inputs. Each input can be
configured to capture an analog input or an IP video stream.
All Trigger NGs support Motion JPEG or MPEG4 compression format and the
RTP/RTSP network protocol.
Behavior Tracking is a domain of Video Content Analysis (VCA) that applies
specific rules to detect and alert numerous violations and irregular conduct:
abandoned objects, stopped cars, perimeter breach, etc. The field of VCA is also
known as Computer Vision.
2.2.
Architecture
The video detection and management system built with one or more Trigger NG
units is comprised of different modules, each fulfilling a specific task. The system
is scalable from a single Trigger NG processing two video feeds, to a large
network analyzing a large number of video cameras. The architecture remains the
same, although the component parts may end up residing on different computer
platforms.
FIGURE 1: TRIGGER NG FRONT PANEL
FIGURE 2: TRIGGER NG BACK PANEL
2.3.
Software Architecture
The system consists of the following modules:
2.3.1.
Video Analytics Engine
The Trigger capturing and analyzing unit captures the analog video from the
camera. Its embedded video analytic engine loads rule-sets known as MSFs that
define the video-based alarm criteria per camera. Video frames are received from
the analog video and then analyzed to detect events that match the loaded rule-
sets.
2.3.2.
Cortex Server
Cortex Server serves as the communications and control backbone of the
application. This program automatically minimizes to the system tray on startup
and runs in the background.
2.3.3.
Cortex Policy Manager
The Cortex Policy Manager is a tool for configuring the system authorization
levels. For each of the authorization levels, there are strict permitted actions. The
tool enables an authorized person (such as an administrator) to add and delete
system users as well as to designate or modify a specific level of authorization for
each user. The Cortex Policy Manager displays a hierarchy of sites, connected
devices to each site, and the number of video feeds on each device. An
administrator can grant individual or grouped users with viewing and/or setting up
permissions for selected sites, devices and individual video feeds. This serves as a
security mechanism to limit the user’s scope in accessing and operating the
system.
2.3.4.
Cortex Viewer
Cortex Viewer serves as the main user interface for viewing the status of the
device and each of its connected cameras, and for displaying live video images
with video tracking overlay.
*The installation includes one Cortex Viewer installed on the same machine for
local operation. The Cortex Viewer is pre-configured to operate with the local
Cortex Server installed on the same machine (local IP Address 127.0.0.1).
2.3.5.
Rules Manager/Device Explorer
The Rules Manager program defines and manages rule-sets that specify the type,
shape, location and other key-parameters of detectable events. Once defined, the
rules are uploaded to reside on the device and configure the operation of the
Video Analytics Engine.
Device Explorer is used to set up the network configuration and advanced settings
of the VDU.

5.2.2.2. Video Transmission Settings
The Video Transmission Settings allow for customization of the format of the
transmitted video images.
When selecting MPEG4 mode, select the Rate Control as follows:
Constant Quality: No Rate Control mechanism is used. The quality of the
compressed video output is fixed by the means of using a constant parameter
for the quantization factor, which is determined by the Base Quality parameter.
This is the only Rate Control related value that is taken into account.
VBR (Variable Bit Rate): A bit stream of variable bit rate is generated by the
VDU. The parameters to be used in this case to adjust the performance and
behavior of the VDU are: Base Quality, Average BR and Maximum BR.
CBR (Constant Bit Rate): A bit stream of constant bit rate is generated by the
VDU. The parameters to be used in this case to adjust the performance and
behavior of the VDU are: Base Quality, Min Quality and Constant BR.
Configure the Rate Control parameters as follows:

Base Quality designates the desired quality of sent frames (the lower the number,
the higher the quality). This is the recommended setting.
Min Quality designates the minimum allowed quality of sent frames (the lower
the number, the higher the quality).
Frame Rate determines how the frames are sent (Full sends all frames, Half
sends every second frame, and 1/3 sends every third frame).
Rules Manager/Device Explorer
V4.5
Page 5-9
Inter Frames determines when a full frame is sent and not just a delta (e.g., 15
would mean every 15th frame is a full frame).
Average BR designates the desired bit rate (between 50000 and 1500000 for CIF,
and between 50000 and 3000000 for 4CIF).
Maximum BR designates the maximum allowed bit rate (between 50000 and
between 1500000 for CIF, and 50000 and 3000000 for 4CIF).
Constant BR designates the allowed bit rate (between 50000 and 1500000 for
CIF, and between 50000 and 3000000 for 4CIF).
NOTE:
For most situations using MPEG4 mode, a Rate Control of Constant Quality is
recommended (setting Base Quality to 7 and Inter Frames to 25).

output is fixed to the camera and appears as a full screen.
Alarmed Camera: The camera that gets an alarm will appear on the analog
video output for at least 5 seconds before switching to the next camera if
needed.
Both: The analog video output displays both cameras on the same display in
smaller size.
You can rescale the image by selecting a percentage from the Rescale Image %
drop down list.
Check the ByPass box to send video only to the Video Out port (without ROI
and Tracking), for example, when the video has lots of objects drawn on the
video that may interfere with a clear view of the scene.

5.2.2.5. De-Interlace Filter
De-Interlace helps prevent visual defects called interlace artifacts or combing
which occur with moving objects in the image. When there is a lot of motion in a
scene the image may be blurred and objects can be duplicated. In order to tell if a
camera is interlacing is to rapidly move the camera and see whether objects are
duplicated or not. The figure below demonstrates this phenomenon.

FIGURE 23: ALARM TAB
5.3.3.1. Sensitivity
The performance of video detection systems is usually measured by the
probability of detection for the desired event / behavior, and by the false alarm
rate. The default sensitivity is tuned to balance these two performance measures.
The sensitivity slider can be used in certain scenarios for better control of these
values. Starting with medium sensitivity (the default), you may select Low
sensitivity for further reduction in false alarm rate with somewhat reduced
probability of detection. Alternatively, you may increase sensitivity to High for
detecting small or low-contrast objects, at the expense of a slightly higher false
alarm rate.

Working with Alarm Geometries
Video-based detection algorithms analyze a stream of two-dimensional video
images, thereby allowing us to define rules and alarm criteria with high spatial
resolution.
Alarms are geometrically specified in terms of detection zones or object
boundaries, by object sizes with optional perspective and by optional ignore
zones. These parameters are drawn on the video display. The Alarm Geometry
window comprises of a Video Display, Alarm Geometry Tabs (ROI, Object Sizes,
and Ignore Zone) and a tab-sensitive Drawing Toolbar. The Alarm Geometry tabs
are displayed when a specific alarm is highlighted and may vary depending on the
Alarm type.

mouse pointer over the edges and then dragging each of its sides to the desired
location. Note that creating a self-intersecting polygon is not possible.
5.5.2.
Object Sizes Tab
When you set an alarm, it is necessary to set minimum and maximum bounds on
the size of subjects to be detected, in order to ignore irrelevant subjects and thus
avoid false alarms.
The bounds are set by a pair of concentric rectangles that represents the maximum
and minimum sizes (horizontal and vertical) of a subject you wish to detect. You
can move the indicators to an image location where it is easier to set the sizes
(possibly pausing the video to a captured object for sizing).
Object Size drawing tools include the Maximum tool
, the Minimum tool
, and the Shift tool
.
5.5.3.
Classification Tab
The Behavior Watch VDUs support the Classification feature which enables
objects detected to be classified as either 'Human', 'Vehicle' or 'Other'. This feature
is only available for the VMD, Path Detection and Static Object alarm types. Note
that Classification is set per MSF and not per individual alarm.
To enable the classification feature, select the Use Classification feature (with or
without perspective) on the Classification tab. The Human size rectangle which
appears can be resized by moving the mouse pointer over the edges and then
dragging each of its sides to the desired dimension. If perspective has also been

Working with Perspective
Video images depict a perspective projection of a 3D world captured by the video
camera. The image location of an object depends on its world location as well as
its distance from the camera that controls how large the object looks in the image.
Equally-sized objects that are located at different distances from the camera will
have different sizes in the image. The nearest object will naturally look larger.
This is known as a perspective distortion.
A significant perspective distortion has to be accounted for, or the Object Size
values defined at one image location will be highly inaccurate at other image
locations, resulting in lower detection probability and / or increased false alarm
rate.
Exact calibration of object size may be tedious and may require information that is
not available from the video images only. We have introduced a way of working
with perspective that is simple, yet accurate enough for our robust detection and
tracking algorithms: you set the object size (a pair of concentric rectangles) at the
nearest possible image location in the ROI, and then set the perspective ratio at the
furthest possible image location in the ROI by scaling down the rectangles in
accordance with that ratio.
The minimum and maximum bounds on subject size are then automatically
linearly interpolated at any image point between the nearest and the furthest point.
Note that if object-camera distance variation across the ROI is small compared
with the object-camera distance at any point in the ROI, then perspective
distortion is insignificant and there is no need to account for perspective.

5.5.6.
Ignore Zone Tab
The Ignore Zone feature is used to define up to three specific areas of an image
where no video analytics will be applied.
IMPORTANT:
Any zone marked to be ignored applies to ALL alarms within that MSF.
Possible usage:
The detection algorithm also detects and tracks subjects outside the detection
zones for improved detection when the subjects enter the zone. Some scenarios
include a high-level of activity that is not related to the desired detection, such as
a road located far from the zone. The ignore zone allows the system to ignore this
area and reduce the computational load for the algorithm.
An ignore zone may encompass a part of a detection zone, when the activity
inside that part is meant to be ignored.
Setting an Ignore Zone:
Drawing tool: Polygon button.
The Eraser button. This button is used for deleting ALL ignore zones.
Used for undoing the last performed operation (only the last action).
When setting an alarm, select the Ignore Zone tab and draw a polygon.
When the polygon is complete, it is filled by a hatched pattern to distinguish
it from a regular detection zone. Up to three separate Ignore Zones can be
created.
Use the Undo button to undo the last polygon edge drawn.
Rules Manager/Device Explorer

5.6.7.
Path Detection Alarm
Description:
Path Detection alarms are used to detect whenever a subject crosses from one area
to another in one specified direction or in both directions. A subject is first
detected in a "source" zone and its motion is tracked to the detection zone. An
alert is issued when the object moves into the detection zone.
Possible usages:
Boundary crossing: Placing both zones nearby triggers an alarm immediately
when the object moves from the source zone into the detection zone. To avoid
the ambiguity that may be encountered when an extended object is
"wandering" around the boundary, the source zone may be displaced from the
detection zone by a distance comparable to the object size.
Motion pattern: In this use case the source zone may be placed in any image
location relative to the detection zone provided that the object is tracked
between the two zones.
Rules Manager/Device Explorer
V4.5
Page 5-37
2-way path detection: Triggers alarm in the use cases above, irrespective of
the path direction: source zone to detection zone or vice versa.

recommended not to add other Alarm Types to the MSF (results in a degradation
of system performance).
5.6.11. Speed Alarm
Description:
The Speed Alarm measures speed and activates an alarm whenever a subject or a
vehicle violates the designated speed bounds. Speed is measured indirectly by
measuring the travel time between two zones. If the ground distance between the
zones is known, actual speed values may be derived. For example, suppose that
the ground distance between the zones (say A and B) is 100m and that a vehicle
has traveled that distance in less than 4 seconds. In such a case, the vehicle has
certainly exceeded a speed limit of 25m/sec or 90 Km / Hour when traveling from
A to B.
Possible uses:
Detecting speed disparities of subjects and vehicles: speeding or traveling too
slowly.

6. ACCESS WATCH (TAILGATING)
6.1. Application Description
Access Watch is a combined video content analysis and access control solution
for real-time tailgating detection, by simultaneously analyzing video data from
two different cameras focused on the same access point and comparing it to the
data received from the access control device.
6.2. Tailgating Detection
Tailgating is the practice of following an authorized and credentialed
individual through an access control point without having or using a separate valid
credential. This evasive practice compromises all security control measures;
therefore detecting tailgating is critical for secure access control. Tailgating is
characterized by the number of people entering being greater than the number of
cards swiped. Configuring tailgating alarm will notify accurately and promptly
when a violation occurred.
6.3. Principle of Operation
Access Watch combines a very accurate video-based directional counting of
people and groups of people with access control integration to detect and alert
upon cases when the number of cards swiped is less than the number of people
counted. As collaborative piggybacking may be too close to call by a single side
view, or a top view camera, Access Watch provides a unique solution to that
problem.
Unlike portals and man-traps, Access Watch does not reduce throughput, as it
“passively” watches the normal access process, alerting only when a violation has
been detected.
Rules Manager/Device Explorer
V4.5
Page 6-54
6.4. Architecture
Our solution uses top and side view cameras located above and nearby the entrance counting
the number of people passing by, a TTL used to notify the edge device about each approved
entering and a TTL used to move the edge device between ready and standby states.
A violation event appears whenever counted number of people is greater than the number of
approval events on a given timeslot, as long as the system is in a ready state.
6.5. Camera Installation
Correct camera positioning and installation is the key to obtaining optimum system
performance as follows:
Rules Manager/Device Explorer
V4.5
Page 6-55
1. For accurate detection, minimum camera height of the Primary Camera (the
distance from the bottom of the lens to the floor) should be 2.5m or 8ft, and the camera should
point vertically downwards (see diagram below).
2. Please make sure the Secondary Camera is aligned to the same direction as the first camera,
e.g. people move from left to right.
3. Accuracy can be reduced by reflections from the floor and by hard shadows. Position the
camera and optional lighting sources to minimize these factors.
4. Make sure the people to be detected are fully visible in the image, even when traveling near
the edges of the detection zone. Increase the height of the camera or change its lens if
required.
6.6. Dependency Rule Topology (MSF Description)
We will use a template MSF for Access Watch rules manipulation. This msf will be provided
when receiving a tailgating license as it allows easy installation.
Rules Manager/Device Explorer
V4.5
Page 6-56
Upon receiving such MSF do the following:
1) Import appropriate msf to feed1 (top view camera) and to feed2 (side view camera).
2) Update the ROI on both feeds.
3) For top view learning counting alarm, do learning.
4) Activate the MSF's.
Please notice that the tailgating MSF will work only if your license supports dependency,
people counting and tailgating licenses.
Below we explain in detail what the MSF's define:
Following table describes system inputs:
Channel name
Channel description
Abbreviations
Video In Feed 1
Top view camera
V1
Video In Feed 2
Side view camera
V2
TTL Channel 1
System state device
TTL1
TTL Channel 2
External verification device.
Each event should be
signaled by a 600ms high
level pulse followed by a
600ms zero level.
TTL2
The rationale is to create for each feed an alarm if number of people counted is greater than
the number of cards swapped (number of cards swapped is received through TTL input #2).
We do this for both top-view-camera (V1) and side-view-camera (V2). We then do an OR
between both alarms (effectively by giving them the same name of 'AccessWatchFeed' and
doing a single event to rename it as 'AccessWatch'), and we do AND to verify that the system
is in a ready state (defined by TTL2).

The Alarm Video Clip Server (AVCS) is an optional application for extending the
Video Detection Unit's capabilities, and enabling the saving of a video clip that
displays the pre-alarm and post-alarm event video images with an object overlay.
The video is sent from the Video Detection Unit and stored on the AVCS for
browsing and presentation via the Cortex Player.
The AVCS works only in the Trigger NG 2 mode and not in the 2S, 1S, 1A, or 2A
modes.
7.1.
Launching AVCS
Either double-click on the AVCS desktop icon
(if AVCS was installed from a
separate CD) or launch the AVC Server application from the Tool menu of
StartUp Application, and then click the AVCS icon which minimizes to the
system tray.

RTP/RTSP VIDEO NODE
You can open an RTP/RTSP video node in QuickTime. If you do not add parameters to the
URI, the default parameters will be used (configurable via the video settings tab in device
explorer).
To open a RTP/RTSP video node in QuickTime:
1. Make sure a video source is properly connected to the first input of your board.
2. Input a URI to your video player.
In QuickTime this is done by choosing Open URL from the File menu or
pressing Ctrl-U on the keyboard:
FIGURE 46: QUICKTIME OPEN URL
The Open URL window appears:
FIGURE 47: URL INPUT DIALOG
3. Type your board’s current IP address.
4. Click OK.
RTSP URI Format
A Uniform Resource Identifiers (URI) is a compact string of characters used to identify or
name a resource on the Internet. The main purpose of this identification is to enable
interaction with representations of the resource over a network, typically the World Wide
Web, using specific protocols. URIs are defined in schemes defining a specific syntax and
associated protocols.
8.2.
General Structure
The URI is built of stream specifications. Each stream specification contains a keyword that
identifies the type of the stream (by which stream handlers are registered in the application),
and optionally a list of parameters that modify the default behavior of the stream.
Rtsp://ip.address/keyword[?param1[=value1][¶m2[=value2]…].]/keyword…
A more detailed example of the RTSP URI format is as follows:
rtsp://ip_address/?multicast{¶m1{=val1}{¶m2{=val2}...}}/video_media{?param1{
=val1}{¶m2{=val2}...}}/audio_media{?param1{=val1}{¶m2{=val2}...}}
Note: Curly braces indicate optional parameters
Where:
ip_address is the address of the board.
multicast section is optional if the user wants multicast streaming (otherwise streaming is
regular unicast).
The user can specify a stream of video_media and/or a stream of audio_media.
Video_media can be “mjpeg”, or “mpeg4”.
Audio_media can be “pcma”, “pcmu” for audio. PCMA and PCMU are G.711 A-Law and μ-
Law, respectively.
Param, val: A list of parameters separated by ‘&’. Some parameters appear on their own,
others have a value. In that case they will appear as param=value. Except as noted, any
parameter not specified in the URI will take its default value from the Web page settings.
The default values given in the following tables are the initial factory settings. With the
exception of “cam” and “mic”, they may all be changed in the Web menu.
Some examples are:
rtsp://192.168.22.59/cam=1&ngop=10…..
rtsp://192.168.0.127/mpeg4&cam=0&imgsize=4CIF&rcmode=CONSTANT_Q&qinit=4
8.2.1.
Mjpeg Mode Example
You can request a stream of mjpeg:
rtsp://192.168.22.59/mjpeg&cam=1&q=70
8.2.2.
Multicast Streaming
Request a multicast stream to the specified address, and use ports 6790 for the video
rtsp://192.168.0.123/multicast=1&mcast_addr=224.1.0.3&mcast_port=6790

8.4.1.
Opening a Stream with OSD
For the first 10 seconds after a stream is opened, three white lines appear overlaid on the bottom of the
video image. The lines contain the following information:
[Device Name] [Device Number]
[Main encoder characteristics]
[IP] [Camera Name]
After 10 seconds and during ongoing streaming one white line appears overlaid on the bottom of the
video image contain the following information:
[IP] [Camera Name]
The content should be minimal in order not to affect processing.
The Factory default mode is a software only mechanism to reset the system to the original factory
defaults. The Trigger has three factory default modes:
State 1: Factory default is not active
State 2: Factory default is active for all none networking parameters
State 3: Factory default is active for all parameters (except MAC address)
The Factory Default state machine is determined by System factory default counter.
State 1: Factory default counter equal 0
State 2: Factory default counter equal 2
State 3: Factory default counter equal 3
The following scenario will clear System factory default counter:
Let system run for more then 10 seconds (steady state)
Push reset push button a short push
The following scenario will move System factory default counter into level 2 (state 2):
Push reset push button a short push
Wait until 4 LEDs are set, followed by clearing at least one of them
Push the reset push button and hold it for 4 seconds
Release reset push button.
Wait until 4 LEDs are set, followed by clearing at least one of them
