Alarm Over IP (Aoip) -IP Module

The development trends of technical protection are increasingly becoming Internet-oriented.

IP_SEC (IP Security) (ip-ac.eu) system eliminates all alarm transmission flaws.
It performs three basic functions:

• Alarm signal transfer from the alarm control panel at the secured building to the monitoring center over the Internet,
• Constant control over the connection between the secured building and the monitoring center and
• 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 alarmcontrol panel over the IP network (ADSL, cable, wireless...) and at thesame time using the possibility of transfer over standard telephonelines 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 communicationwith the operating software the monitoring center.

Transmitting alarm over Internet and backup networks

Once the alarm goes off at the secured building, the IP_AC interface seizes it, reads the CONTACT-IDinformation (additionally it can be adapted to any other alarmprotocol), reformats it into an IP package and sends the package overthe IP network to the monitoring center.

Thesignals received by the Input/Output module (which is connetcted to theIP_AC module) can be handled at the same way as alarm signals.

There is an alarm receiver called IP_RECinstalled in the monitoring center enabling alarm signal reception andcontrol over the connection to the secured building over the Internet.

Data transfer takes about one second and does not exceed 70 bytes, asize which does not slow down the Internet connection at the securedbuilding or ar the monitorting center.
The capacity of a ping coming from the receiver and being send back isa little over 30 bytes which also does not slow down the Internetconnection.

What happens when Internet connection is off?

Ifthe Internet connection at the secured building is disconnected, analarm goes off at the monitoring center. The disconnection is alsodetected by the IP_AC interfacewhich tries to transmit the event over the telephone line or GSM (GPRS)network (secondary transfer can be prioritized - telephone line or GSMnetwork). If the secondary connections are disconnected as well, analarm of general disconnection with the secured building is sent to themonitoring software by the IP_REC receiver.

Whatis the most important is that the monitoring center keeps CONSTANTCONTROL OVER THE OPERATION OF THE INTERNET LINE at the securedbuilding. The receiver and the interface constantly check theirconnection in preset adjustable intervals (pings).
