1.2. DESCRIPTION AND DATA
1.2.1. DESCRIPTION
a. Purpose
TASC Series Features Built-in Analytics Advanced Motion Detector
in TASC cameras utilizes a state of the art algorithm that signifi-
cantly reduces false alarms normally caused by movement of nat-
ural (background) objects such as leaves, clouds or small animals.
Object Tracking function when activated will capture and track all
moving objects and register their path in the field of view. Object
Counting function counts all captured objects. Trip Wire function
allows users to set up any configuration of virtual tripwires in the
field of view, that when crossed in preset direction, will trigger an
alarm. Perfect solution for passages, driveways or perimeter secu-
rity. Trip Wire can also be used to detect wrong direction movement
on roads. Speed measurement feature turns your TASC camera
into speed radar that automatically measures and records speed
of all moving objects in the field of view. When applied inside Clean
Zone can also set off an alarm when a moving object exceeds user
preset speed limit. Clean Zone solution allows users to set up a
perimeter and create alarm rules that best resolve specific secu-
rity issues by activating any combination of functions mentioned
above as well as Clean Zone specific algorithms such as Loiter-
ing Detection and Dropped Objects Detection. Loitering Detection
function sets off an alarm if an object stays in the Clean Zone longer
than a specified period of time. Dropped Objects Detection function
alarms user of all objects left in the field of view. Tampering alarm
informs an operator if the camera is mechanically manipulated with
or if the view is obscured. ATN Corp is proud to present the new
TASC series Thermal Acquisition Security Cameras! 18 years of
experience in enhancing vision, vast expertise in development of
thermal devices and recent advances in electronics enabled us to
create these easy to use products with almost unmatchable set of
skills that also come at very reasonable price. Our new cameras
utilize advanced thermal technology and optics used in the univer-
sally recognized Thor series scopes, together with Pan/Tilt capa-
1-6
bilities, state of the art built-in analytics and features like autofocus
that were previously available only in top-end professional models.
TASC series caters to the most important need we all share - the
need for security. We truly believe that it can become an invaluable
instrument in outperforming potential threats to personal security
and safety of your possessions.
b. Function Description
1. Focus length/rotation speed auto matching technology
In the situation that focal length is long, the imager will be dis-
torted because thermal speed dome responses so fast that even
a tender touch of joystick could make the picture shift rapidly. Base
on human design, this speed dome thermal imaging camera can
automatically adjust pan and tilt speed according to the focal length
to make the manual trace operation easier.
2. Automatically flip
If operator keeps press the joystick after reaching the limitation in
vertical direction, the lens would automatically flip 180°, so we can
monitor the back scene.
3. Set and call preset
Preset is a function that we can store the angle of PTZ and the
length of focus to the memory, and the thermal speed dome could
adjust itself to reach the angle of PTZ and the length of focus when
you call the preset.
4. Tour
Automatic tour, which arranges presets in the wanted order and
dwell time by programming,is a build-in function of this thermal
speed dome. With a command, the camera of thermal speed dome
would tour automatically and continuously according to the route
and dwell time preprogrammed.
5. Automatically scan
This high speed dome camera can automatically and repeatedly
scan 360°in both high speed and slow speed.
1-7
6. Limit scan
To set the starting point of limit scan by using the limit start com-
mand in the control keyboard,then control the joystick to move to
the end point of limit scan with a certain speed. After calling the limit
scan, camera will automatically scan between the start and end
points with the speed which joystick moving.
7. Home point
Home place is a function that if there is no operation in a long time,
dome thermal camera would back to a certain important preset
place. Waiting time before home point function starting is from 1 to
255 second.
c. Features
TASC has the following important features:
Advanced Thermal Detectors with resolution 336x256 or
640x515 pixels.
High quality thermal image with 9/30/60 Hz frame rate.
Built-in video analytics.

AC power supply
didn’t connect with
speed dome in right
way.
2. Power failure or
transformer break-
down.
1. Check whether thermal speed
dome connect to 24V AC power
supply. Make sure that the well
connection between speed dome
and 24V AC power supply.
2. Check whether the power supply
is in working order and whether 24V
AC transformer work normally.
After self
testing,
keyboard
can’t control
Thermal
speed dome.
1. IP address Switch
of speed dome set
incorrectly.
2. Reverse connec-
tion and open circuit
of RS485 control
bus.
3. RS485 control
bus breakdown.
1. Reset DIP switches according to
DIP switch setting table.
And make sure that the IP address
speed dome is the same with that
of keyboard.
2. Check connection of RS485
control bus, guarantee well and
correct connection.
3. Refer to common sense of
RS485 control bus.
Fan
don’t work.
1. Poor fan connec-
tion.
2. Ambient tempera-
ture is below 10°C
1. Make sure the well connection. If
fan don’t work when connection is
well, please contact supplier.
2. Make sure that thermal speed
dome work in proper temperature.
The picture
is fuzzy.
1. Thermal speed
dome is in the
manual focus status.
2. Transparent lower
dome is not clean.
1. Change the manual focus status
to auto focus status.
2. Clean transparent lower dome.

THE GENERAL KNOWLEDGE OF RS485
4.2.1. BASIC CHARACTERISTIC OF RS485
RS485 is a half duplex communication bus whose impedance is
120Ω. Its carrying capacity is different because the different con-
nection interface, IC is 32-128 actual load (including master equip-
ment and slaves equipments).
4.2.2. RS485 TRANSMITTING DISTANCE
When 0.56 mm (24AWG) twisted pair line is used as the commu-
nication electric cable, there are different transmission distance
according to different Baud rate setting. Maximum transmission
distance and corresponding.

Maximum
distance
2400 BPS 1800 m 4800 BPS 1200 m
9600 BPS 800 m 19200 BPS 600 m
The max transmission distance would be shortened in conditions
as: when this product uses a slim communication electric cable
or the thermal speed dome is used in the environment with strong
electromagnetic interference or there are many equipments con-
nected to control bus, vice versa.
4.2.3. CONNECT MODE AND TERMINAL IMPEDANCE
The RS485 requires daisy-chain connection mode, and two 120Ω
terminal impedances should be connected. The mode was showed
as figure 4.1. Simplified connection mode shows in figure 4.2, make
sure that the distance of D can’t be more than 23 feet (7 meters).

4.2.4. QUESTION IN APPLICATIONS
In the actual construction, user often adopts y-junction connection
mode whose terminal impedance are connected with the furthest
two equipments (as B and D in figure 4.3). But it doesn’t comply
with the use requirement of RS485 industrial standard, so it would
lower the reliability of control signal by causing the problems such
as signal reflection and a weaker antiinterference ability in the
situation that there is long distance among every equipment. Its
reflecting phenomenon is that speed dome isn’t under the control
completely or under control off and on or can’t stop from automat-
ically running. We advise to use RS485 allotter which can avoid
problems and increase the communication reliability in the situa-
tion mentioned above by change y-junction mode to the connection
mode complying with RS485 industrial standard.
