ATM TEXT INTEGRAION
is a very popular function in CCTV field. Specially
for bank application, if we can overlay the text information such as card number, amount in the
video, and search by card number, it will be very helpful for the security management of bank.

Method of text integration
Method of text integration A
Method A---RS 232
DATA
ATM
DVR
ATM communicates with DVR via RS232 ports. After a draw, ATM send a special data packet ,which include of the card number,
Transaction number, amount, etc, to DVR followed a protocol that both sides know.
So, in this way, the protocol is very important and need customized DVR software.
And because the hardware limitation, one RS232 port can only communicate with one device. That means one ATM need one DVR!
Method of text integration A
Method A---Solution
This solution need a special communication box which pick up
the text information and overlay it to the video.
The problem is that you can not search the video by the text information.
Method of text integration B
Synchronous Data Link Control
Method B---SDLC
SDLC is developed on IBM industry system, Some ATM system use this, and this system need
A special hardware IC supports. This causes the high cost of DVR and a narrow range of application

DATA
DVR need a special SDLC IC.
Method of text integration C
Method C---TCP/IP NETWORK SNIFFER
DVR
ASCII DATA
One DVR can communicate with
Several ATMs synchronously.
We select this method as our solution
TCP/IP network is very popular in internet and LAN network, it’s the widest network in this world
And, mostly, a standard network communication method.
Our Solution
Current solution
Theory---Capture the data packet
AN ASCII DATA PACKET
Monitor from here ,we can get all of
those data packets between
ATM and Bank, and we can copy one
Data packet from Bank center to ATM
Data packet from ATM to Bank center
Current solution
Theory--- Analysis of ASCII data packet

In this Sample:
40 is the FLAG of this data packet, it means
what kind of data packet it is. In this data packet,
We can get all of those information that we need
from this kind of data packet.
Actually, we can find this kind of data packet after
Check those data packets between ATM and Center
An ASCII data packet
via TCP/IP network
There are many data packet in
the network, some of them have
the useful information that we need.
Such as this data packet, we can
get Card number,Amount,
Transaction number.

TRAN NO

So, if we can find this kind of data packet and
set those parameter, such as offset, length, we
can get any information that we want.
Current solution
Software interface & configurations
ATM NO: Normally, it’s 4, That means one DVR can communicate with 4 ATMs.
RECORD CHANNEL: The video channel that TEXT will be overlay on.
Source IP: IP of ATM or BANK CENTER
Destination IP: IP of BANK CERTER or ATM
Frame ID: The flag of data packet
the DVR checks every data packets, and pick up the data from
offset position, end as length bit, and compare it with the Key, if
it’s equal to the key, it will look it as the one that we need.
Account, Trans No, Amount:
Take those data as the rule of your setting.

Different interface between different software version.
In this way, we can capture any parts of the data packet that we need,

We also provide customized software service for actual applications.
