Product Description

Functions and Features: An Overview

The video alarm system ACom carries out remote surveillance and remote control of vid­eo surveillance devices via ISDN or other public telecommunication networks. The sys­tem can easily be connected to a multiple ISDN-connection and can send data either to
an internal substation or to an external connection. In order to receive the data you will
need a computer programmed with the CMConnect (part of the delivery) or another
H.320-compatible outstation such as a video telephone. You can enter simple control
and configuration demands for the models ACom6A and ACom6HA already with the dig­ital dial of an ordinary telephone.

Apart from the basic system ACom6, you have the choice between several other models.
In addition to the transmission of images, the model ACom6A enables you to transmit

audio data as well (from an intercom or another talk-back-circuit).The device transmits
the audio data bidirectionally and parallel to the transmission of pictures.

The model ACom6H is equipped with an integrated hard disc and a memory capacity of

2.1 GB. The hard disc records video data, depending on its configuration, either in a pro-

grammed sequence or “event-driven“, i.e. in the case of an alarm.
The model ACom6HA is equipped with both audio function and hard disc (2.1 GB).
Ideally, ACom is transmitting via the digital communication network ISDN (Integrated

Service Digital Network). All ACom-devices have an integrated ISDN-adapter. Rapid
transmission of large data volumes is best conducted simultaneously on both B-channels
of a basic ISDN-connection S
channel, too. The analog phone networks or GSM-networks (Global Systems for Mobile
Telecommunications) can also be used for the sake of data transmission. For these pur­poses, however, you need an external modem.

The device is capable of compressing the data in compliance with the norm H.320 in or­der to accelerate the data transmission. This enables it to communicate with other
H.320-compatible systems (such as video conferencing systems or video telephones).

Apart from video data, ACom is capable of transmitting control commands for movable
cameras and other appliances. The range of controllable appliances is steadily being ex­tended. You may contact your local CBC-branch for more detailed and up-to-date infor­mation. Two relays can activate further switch functions such as door openers or lamps.

In order to turn work with the ACom system into a convenient experience, the software
CMConnect has been designed to make your life easier. You can watch and evaluate vid­eo pictures on a computer and easily control the peripherals/appliances connected to the
ACom with mouse and keyboard. The programme has been developed for Windows 95/
98/NT and is delivered with a manual of its own.

For the purposes of local installation and configuration of your ACom, you should make
use of the software CMCtrl which is delivered together with this product.

Assembly

Assembly

The ACom is suitable both for operation as a desktop and for being mounted on the wall.

Attention!

z

❚ Do not set up the device in the immediate vicinity of radiators or other heat sources.

Avoid sites which are exposed to direct sunlight.

❚ Create sufficient space for lines and cables.
❚ Ensure sufficient ventilation of the device.
❚ For cable connections, use only cables which have been part of the delivery or are

otherwise suitable and which help to suppress electric interference.

❚ When laying out the lines and cables, make sure that they cannot be easily damaged

and ease wherever possible tensile loads and stresses.

Wall-Mounting

The device is intended for indoor use. Do not expose it to either extreme tem­peratures or extreme humidity at any time and choose its setup site accord­ingly. The ambient temperature must fall within the range from 5 to 40 °C at all
times, the relative humidity of the air must not exceed 80 %.

At the back of the ACom you will find four fixing holes that you can use for mounting the
ACom on the wall.

☞

• Push against the flaps by the side and lift the lid to open the casing.

• Screw the ACom to the wall by using the four fixing holes.

Important

Mount the ACom in immediate vicinity to your NTBA for it to be the first device
to be connected to the S

-Bus.

Connections

You have two options of feeding the connection cables through into the interior of the
casing. You either use the openings in the back of the casing or you punch out the desig­nated section at the bottom side of the casing and feed the connection cable through the
hole.

Camera

You can connect a maximum of six cameras or other video sources. If you use only one
camera, you can connect it either to the BNC-socket marked Video1 or the first pair of
terminals V1. You can connect any additional cameras to the remaining terminals.

☞

• Connect the video camera with a video cable (75 ohm, BNC-plug) to the BNC-socket
of the ACom.

or

• Remove terminal block from the socket.

• Put signal conductor on terminal V1.

• Put shield on terminal ⊥.

• Connect additional cameras where applicable.

• Insert terminal block in socket.

• Lead cable around the pivot several times (to reduce tensile loads and stresses).

• Switch on terminal resistance of the video connections not in use. Turn the respective
DIP-switches to position ON.

ISDN

You can easily connect the ACom to the S
cable which is part of the delivery.

Attention!

Make sure that the ACom is the first device you connect to the S
ately after the NTBA. This is the only way for you to ensure that the ACom is
capable of emitting an alarm even if the ISDN-line has been damaged. Addi­tional appliances (phone, fax) may if necessary be connected to the ISDN-out­let of the ACom (ISDN OUT).

Assembly

Example:

In the course of a burglary in your home, the ISDN-line is short-circuited at a free ISDN­socket, thus paralysing all additional ISDN-connections. Only the first device (e.g., an
ACom installed in your basement) is not affected and still capable of emitting an alarm.

• Put the plug into the socket ISDN IN of the ACom and the phone socket until they
snap in with a clearly audible “click“.

• If necessary, connect additional appliances to the socket ISDN OUT of the ACom.

Modem

If you cannot use the ISDN for ACom, you may alternatively connect an analog modem
to the serial interface COM1. Data transmission via analog phone networks, however, is
considerably slower. This is why connections via analog networks does not support the
transmission of audio data. Video data and configuration parameters, meanwhile, are
transmitted as they would be with an ISDN-line.

The system supports all modems with an asynchronous RS232-interface and which op­erate with the Hayes command set. Once you have connected the modem, ACom auto­matically recognizes it and sets the highest possible data transmission speed.

☞

Screen

You can connect a local surveillance monitor to the video output OUT of the ACom, if you
want to check the camera pictures during the installation in situ.

• Remove terminal block from socket.

• Put signal conductor on terminal V.

• Put shield on terminal ⊥.

• Insert terminal block in socket.

• Lead cable around the pivot several times (to reduce tensile loads and stresses).

Alarm Inputs

The alarm inlets of the ACom allow you the intrusion of one or several alarm triggers such
as door contacts or sensors. If you configure the system accordingly, an alarm trigger
can for instance cause the automatic establishment of a connection between ACom and
CMConnect.

Important

For best results, use modems of an identical make on either side of the data
transmission process.

14 ACom6

Assembly

At the connections Alarm IN 0-3, you will find four potential-free alarm inputs. The poten-
tial-free alarm inputs are galvanically separated (by optical couplers) from the other
ACom components and thus give you the greatest possible protection from outside in­terference. They need a direct voltage between 5 and 12 V. When connecting the alarm
inputs, please make sure that you are connecting the polarry correctly.

Alternatively, there are four potential-linked alarm inputs at the connections Alarm IN 4-7.
Here, you may connect switches or closing contacts directly without the need for any
separate power supply. Connect the respective input and the common ground.

Attention!

z

• Remove terminal block from socket.

• Put conductors to the terminals in strict compliance with their polarity. Ensure correct

assignment (+. –. ⊥)

• Insert terminal block in socket.

• Lead cable around the pivot several times (to reduce tensile loads and stresses).

Connection Outputs

The ACom is equipped with two relay outputs (Rel1 and Rel2) for the connection of exter­nal appliances such as lamps or alarm sirens. The relays function as throw-over switches
and the symbols Open, Closed at the screw terminals each refer to the resting state.

In cases of galvanic separation by optical couplers a common ground should
under no circumstances be used. External voltage must not exceed 12 V. En­sure correct polarity.

Attention!

z

• Remove terminal block from socket.

• Connect the contacts in the middle and to the left. The relay functions as normally
close.

or
Connect the contacts in the middle and to the right. The relay functions as normally

Audio Connection

☞

ACom6A and ACom6HA are both equipped with two audio inputs and outputs respec­tively at the audio terminal block. Here, you can attach two parallel audio and video connec­tions such as a microphone, a loud-speaker and a phone receiver. At any one time, howev­er, only one of these may be active.

The audio signals are transmitted bidirectionally and simultaneously with the video sig­nals. This can be used, for instance, to activate a loud-speaker at the surveillance site or
to listen to an intercom at the entrance door. Transmission of audio data is generally only
possible via the ISDN-network, not by using ordinary phone lines.

Video/Audio

On this tab, you configure the parameters for audio and video transmissions. You can
switch the video inlets.

Audio

ACom6A and AComAH transmit an audio signal in their basic configuration. You can de­activate the audio transmission for transmitter separately and select the compression
mode. You can adjust the audio level of the ACom (input and output) in order to improve
the quality.

Furthermore, you can also activate the automatic audio transmission in the course of the
establishment of a connection. If you also transmit audio data, the line capacity for the
transmission of the video image will be reduced by 56 kbit/s. This may reduce the picture
quality (lower frame rate and/or reduced picture resolution).

• Select the right options by clicking the respective fields for transmitters and receivers.

ACom6 27

Configuration with CMCtrl

• Click Level. A dialogue window will appear on your screen.

• Select the required settings for Volume and Input sensitivity by moving the scroll bar
(keep the mouse button down).

• Click on the X in the title bar to close the dialogue window.

• Set the audio parameters of your computer by using the respective Windows pro­grammes (such as the programme for your sound card).

• Click Off when you want to finish the audio transmission.

The sound card terminates the playing back. The transmission capacity taken up by the
audio signal until now will again be released for use by the video signal. This immediately
improves picture quality.

Video

When a connection with an ACom has been established, you can switch between the six
video inputs. You can determine the video play back quality. You have the choice between
a high-resolution and a lower-resolution mode.

❚ The Common Intermediate Format (CIF) supports a local resolution of 288 lines x 352

dots. This is the resolution of the default setting.

❚ The format Quarter CIF (QCIF) has a resolution of 144 lines x 176 dots.
Selection of the lower resolution may prove to be sensible if you prefer a higher frame

rate (refresh frequency) to a high resolution. The resolution of the video signal currently
received is identified in the field Video inside the control window: green indicates higher
resolution (CIF), yellow the lower resolution (QCIF).

Furthermore, you must find a compromise between the conflicting demands of high im­age definition (sharp focus) and a rapid, “lifelike“ representation of movement inside the
picture.

If your priority is a high refresh frequency, the picture quality in terms of sharpness and
focus will decrease in direct proportion to the increase of movement in the camera range
(blurred and distorted images). If you prefer pictures with the highest possible sharpness
and a clear focus, this means that the refresh frequency decreases when there is move­ment to be detected. If movement is anticipated only in a limited part of the frame, you
may be well advised to prioritise sharpness. The smart compression process is capable
of refreshing only the parts of the images concerned by (spatially constricted) move­ments. The unchanged rest of the picture will be represented with the highest possible
degree of sharpness.

By selecting the option PiP (Picture in Picture) you can display the image of the local
camera as a part of the surveillance frame.

• Click on one of the fields Camera to receive the desired camera image or video signal.

• Define your choices by clicking the respective options.

• Move the scroll bar between Sharpness and Motion to create the right balance.

The text will always be displayed, whether there is an alarm or not.

(12/99)

ACom6 29

Configuration with CMCtrl

If alarm active

The text will only be displayed in case of an alarm.

Hold

The alarm signals (text and symbol) remain displayed once the alarm is over.

• Enter the required text in the text panel Alarm message:.

• Click Set to save the text.

• Click the desired option or control box.

Alarm input activation

You can activate the available alarm inlets of the ACom individually and add short texts
for prompt and easy identification. Apart from the alarm inputs, you are free to choose
additional events which will trigger an alarm. An alarm can be automatically caused by an
interruption to the ISDN-line, the modem-line or the video connection. Status panels iden­tify the present status of an alarm trigger:

Grey: not activated
Green: activated and in rest mode
Red: activated and in alarm mode
The ACom gives you the option of using the alarm input 0 as master alarm. This may be

useful when a key switch is being used to activate the system. If this option is activated,
the alarm input 0 must itself be active (red status panel) to clear all other alarms.

You can decide for every individual alarm input whether it is meant to trigger an alarm in
the case of voltage detected (On) or not detected (Low active).

• Select the right options by clicking the respective boxes.

• Enter a text (description) for every alarm inlet in the text panel provided.

• Click Set to save the description.

Motion detection sensitivity

All ACom models are equipped with an integrated video sensor capable of identifying
changes in the video signal based on image processing according to the norm H.320.
These changes are caused mainly by movements within the visual range of the camera.

The sensitivity of the video sensor can be adjusted so that a certain “movement threshold“
must be crossed before an alarm is triggered. The threshold values range from 0 ... 15 with
the highest value representing a maximum of sensitivity.

30 ACom6

Configuration with CMCtrl

The video image is divided into 242 square cells (regions). You can activate or deactivate
all cells.

For the video sensor to function properly, the following pre-conditions must be met:

❚ At least one alarm call number must have been entered for the video sensor.
❚ All cells (regions) must have been activated.
❚ The sensitivity must have been set at a value above zero.
❚ Where applicable, the master alarm must have been activated.

☞

• Click in the control box On to activate the video sensor.

• Set the required level of sensitivity by moving the scroll bar to the desired value (keep
the mouse button down).

32 ACom6

Configuration with CMCtrl

Output Settings

The switch functions of the available relay outputs of the ACom can be defined individual­ly. Each relay can be assigned the function of normally open (rest status open) or normal­ly closed (rest status closed).

By selecting the switch times you also determine whether the switch relay in question is
meant to react in a bi-stable or monostable manner. Example: When a lamp which has
been turned on by an alarm is meant to remain switched on after the end of the alarm,
you would have to select the option Forever. If a siren which has been switched on by an
alarm is meant to emit a sound for the duration of 45 seconds, you would have to select
the option 45 (seconds).

Attention!

z

• From the list boxes, select the rest status for each relay.

• Select a switch time for each relay.

Under normal circumstances, you would define the function of the relays by the
choice of terminal. Therefore you should choose the option In idle state the

Access control

Any establishment of a connection to a protected ACom requires the password, no mat­ter which side the call is coming from. You can, however, turn off the password protec­tion for the case of an alarm. This is a useful step for unmanned alarm centres which are
accessed by the ACom via GSM- or modem connections. The connection will then be
established also with devices which are password protected.

• Click in the control box Disable Password protection on alarm to turn off the access
restriction in the case of an alarm.

Important

You can only ever change one of the two passwords at any given time. If you
want to change the other password, too, you will have to open the dialogue
window again.

Other Settings

You can set the internal calendar clock of the ACom by taking over the system time of
the computer. The present ACom time is displayed in the text field. For prompt and easy
identification, you may assign a name and an identification number (ID) to the ACom.

38 ACom6

Configuration with CMCtrl

You can enter an identification number for the ACom (no more than 12 digits). This
number is to be read during the establishment of any connection before (if applicable) a
password is entered. This allows you to identify which ACom is calling even if the devices
are password protected. It is not permitted to give the same ID-number to two or more
different devices.

• Click on Set to take over the system time of the computer for the ACom.

• Enter a name in the text box Unit Name and click on Set to save your entry.

• Enter a number in the text box Unit ID and click on Set to save your entry.

EAZ/MSN

The MSN is a complete call number (without area code). You must programme the entire
call number to which the ACom is meant to respond. The ACom will only accept the call if
the call number as dialled is identical with this MSN.

• Enter the number in the text box EAZ/MSN: depending on the protocol in use either
the MSN (entire call number) or the EAZ (last number) of your ISDN-connection.

ISDN-protocol

You can perform different settings for the ISDN-connection. You may, for instance, define
whether the connection from the ACom will be operated as a switched line or as a non­switched line via one or both of the B-channels.

• Select the ISDN-protocol applied from the list box.

ACom-HW Version/ACom-SW Version

These are the generation numbers (version numbers) of the hardware components and
the software installed in the ACom. Write down these numbers before you contact any
branch of computer services.

Modem init string

by using a single ISDN-channel. This may make all the difference in the case of
an alarm.

Redialling

You can determine how many attempts the ACom is meant to perform in order to estab­lish a connection and in what intervals. This setting applies to all call numbers.

• Select the required settings from the list boxes.

Output actions

You can assign a number of actions to the available switch outputs of the ACom. You can
determine

❚ to what events an output responds (Follow),
❚ how an output responds in case a connection is interrupted (After Disconnection).

42 ACom6

Configuration with CMCtrl

No Change

The output does not respond to any of the following events.

Camera 1 ... 6

When you select a camera, the output is activated. This allows you, for instance, to
switch on a spot-light to illuminate the scene.

Connection

The status of the output responds to the status of a connection. An existing connection
may for instance be signalled by a control lamp.

Local Input 0 ... 6, Remote Input 0 ... 6

The status of an input is passed on to the output. Example: on activating an input via a
door contact the output will switch on a siren. Inputs and outputs of two ACom-devices
may also be cross-connected to make the switch relays follow the inputs of the other
device. This allows you, for instance, to turn on a spot-light on a remote site by using a
switch in the local control station. Vice versa, an alarm sensor at a remote ACom can
trigger a siren in the control station.

Alarm Sources

Apart from the inputs, internal alarm events (ISDN, modem, video sensor, movement)
can also be used for switching an output.

• Select the required actions for every switch output.

Input Actions

You can define the switching of the video inputs for the ACom. You can set which alarm
input activates which video input. On the basis of this configuration, you can switch both
local and remote cameras to a keyboard which is connected with the ACom without us­ing a computer programme.

As long as no connection has been established via the phone network, the local video
inputs are being activated; when a connection exists, the video inputs of the remote
ACom are used.

You can rule separately for every input whether a local or a remote video source is to be
activated. The setting - - - - - - - - does not cause any change.

Hold Function

When several alarm sensors (such as movement detectors) are connected to the ACom,
it may happen that different sensors trigger an alarm in rapid succession and thereby
switch on the cameras assigned to them. Such multiple switching actions can be avoided
by activating the holding function. If you have activated the holding function, only the first
alarm will cause the camera image to be offered. Any further alarm will not have a bearing
on the camera picture as shown.

Functional Test

The ACom offers a large variety of configuration and connection options. You should
therefore confirm that it functions properly and according to your requirements before
you put it into service. This way you ensure that the ACom will give you the required
service in case of an alarm.

Check the following functions:

❚ the ACom can be accessed (by dialling) in remote mode
❚ the ACom transmits all the required data
❚ the ACom dials the alarm numbers as saved
❚ the ACom responds to alarm events according to the configuration
❚ CMConnect ensures correct control of cameras and other peripherals (where applica-

ble)

❚ ACom6H and ACom6HA: the optional hard disc saves the data as specified in the

configuration

❚ Service and user password protect the ACom from unauthorised access

Attention!

z

Make sure that the service switch is always switched to Betrieb. Otherwise,
the password does not protect the ACom from unauthorized access any­more.

MFD-Control

Modern telecommunications networks support Multi-Frequency Dialling (MFD). This
means that on dialling you are hearing a succession of high-pitch tones. The models
ACom6A and ACom6HA allow you to enter simple control or configuration commands
by using the dial of a telephone if you are operating them via an ISDN-line. The ACom
confirms correct commands by a brief answer signal and responds to non-valid com­mands with a long tone.

☞

Before controlling the ACom by MFD, you will have to identify yourself by entering your
password. A user password gives you access to some of the control functions of the
MFD-code. A service password gives you access to all MFD-codes.

(12/99)
