ALARM OVER IP

Transmitting alarm over IP and backup networks |

Once the alarm goes off at the secured building, the IP_AC interface seizes it, reads the CONTACT-ID information (additionally it can be adapted to any other alarm protocol), reformats it into an alarm over IP package and sends the package over the IP network to the monitoring center.
The signals received by the Input/Output module (which is connetcted to the IP_AC module) can be handled at the same way as alarm signals.
There is an alarm receiver called IP_REC installed in the monitoring center enabling alarm signal reception and control over the connection to the secured building over the Internet.
Data transfer takes about one second and does not exceed 70 bytes, a size which does not slow down the Internet connection at the secured building or ar the monitorting center.
The capacity of a ping coming from the receiver and being send back is a little over 30 bytes which also does not slow down the Internet connection. |

What happens when Internet connection is off? |
|
|
|
|
| |
If the Internet connection at the secured building is disconnected, an alarm goes off at the monitoring center. The disconnection is also detected by the IP_AC interface which tries to transmit the event over the telephone line or GSM (GPRS) network (secondary transfer can be prioritized - telephone line or GSM network). If the secondary connections are disconnected as well, an alarm of general disconnection with the secured building is sent to the monitoring software by the IP_REC receiver. |

The development trends of technical protection
are increasingly becoming Internet-oriented. For this reason our company GLOBTEL has developed its own application for transfer and control alarm data transfer over the Internet. Until now, the alarm signal transfer to the monitoring center has been most frequently performed over classic PSTN telephone lines or GSM networks, known to have certain disadvantages decreasing reliability and quality of the connection to the secured building.
IP_SEC (IP Security) system eliminates these flaws. It performs two basic functions:
 Alarm signal transfer over IP from the alarm control panel at the secured building to the monitoring center over the Internet and
Constant control over the connection between the secured building and the monitoring center.
There is also an alternative function, designed for higher reliability and false alarm reduction:
Alternative alarm signal transfer over telephone lines and/or GSM (GPRS) networks. |
|
|
The IP_SEC system consists of two components:
The IP_AC interface (IP Alarm Communicator) is a communication device enabling alarm signal transfer from the alarm control panel over the IP network (ADSL, cable, wireless...) and at the same time using the possibility of transfer over standard telephone lines and GMS (GPRS) networks as backups.
A receiver unit called IP_REC (IP Receiver) is installed at the monitoring center enabling alarm signal reception, control over the connection to the secured building and communication with the operating software the monitoring center.

The IP_SEC system, a system for alarm message transfer over the Internet, is designed for general use (natural persons, small companies...) as well as for more demanding users (financial and national institutions, shopping centers...). |
