ProductsDigital Receiver
Most security alarm panels have a digital dialler built in as a standard option. A digital dialler uses the conventional telephone service or PSTN (Public Switched Telephone Network) to transmit signals to the monitoring centre.
Control Room utilises the very latest equipment including; FE 900 Digital IP Receivers which have a host of added features, such as Caller ID handshake assignment allowing more secure, efficient and faster transmission acknowledgement. CID Signal tracking, Handshake listen and record for diagnostics and a whole lot more.
Diallers are the most common method of communicating to a monitoring service; the initial outlay is very low however ongoing costs can fluctuate dramatically because the Client (end user) pays a local phone call cost every time the alarm panel communicates with the Control Room Monitoring Centre.
As part of our Total Quality Management plan we utilise 1345 **** numbers, the benefits of these numbers are:
Redundancy is provided to the end user by way of provision for the alarm panel to report to two separate 1345 numbers which in turn are connected to two separate answer point numbers on different PSTN networks and with two dialler receivers. This makes the transmission path fully duplicated but it is still not constantly monitored. It is strongly recommended that 1345 numbers be used rather than the standard 10 digit numbers. Should our (Control Room) PSTN lines fail the 1345 number is automatically re-routed to our Multi-Path IP SG2 receiver.
Portability- Should our monitoring centre relocate to a new exchange area there is no added cost to the Bureau or their client for reprogramming the Alarm System. The transfer can take place seamlessly in an instant.
Priority – 1345 **** numbers have priority in the event of service interruptions and changes to the ever expanding Telco networks, thus saving the cost of reprogramming alarm systems.
Cost – We receive rebates from Telco’s for traffic across the 1345 **** numbers and these rebates are used to offset monitoring fees to the customer.
The use of a dialler as the transmission method is based on the risk assessment for the premises as contained in Australian Standard AS2201 Part1 (Systems Installed in Clients Premises), and the specifications and limitations are contained in AS2201 Part5 (Alarm Transmission Systems).
GSM
GSM is used to transmit digital alarm signals as a backup to, or to replace, the PSTN Telephone Digital Dialler. A GSM module containing a SIM card is included in or added to a security alarm panel by the Alarm Installer to allow reporting over the GSM Network, normally sharing with mobile phone services supplied by Telco’s.
Where GSM is used it should be realised that on most occasions it shares the network with voice communications which contains many users, a voice priority in demand, a complicated switching between cells, and variance in signal strength. Alarm Data over GSM Networks is sometimes corrupted and messages lost.
GSM over a VPN (Virtual Private Network) has the highest availability and reliability but, it is recommended that the user be aware of the limitations and should not compare the service to the Multipath Service or (Securitel Monitoring even with its Limited availability). It is an alternative to Dialler Monitoring and as a Backup to Dialler Monitoring provides better availability.
Some systems also use the SMS (Short Message Service) path to transmit signals but this should only be used for low priority messages not alarm conditions as SMS is a “Store and Forward” method with no time requirements for message delivery.
GPRS
Control Room offers both Permaconn and SG2 GPRS Solutions. GPRS is designed to meet Class 2, 3 & 4 in accordance with AS2201.5.In an emergency it doesn’t make any difference if the telephone line is out because some one intentionally cut the cable or because high winds knocked a tree down on them - the message needs to get through. GPRS has a permanent wireless connection that ensures all alarm messages are received by the Control Room Central Monitoring Station without the need for phone lines.
Benefits;
• No telephone lines to cut.
• Permanent online connections.
• Choice of polling plans; 4 Hour, 1 Hour or 90 Seconds.
• Compatible with most existing Alarm Systems (including Digital Diallers).
• Fixed Monthly Costs.
• GPRS coverage from Telstra or Optus.
Multi-Path IP
Multi-Path IP is control room redundancy solution that can avert 100% of control room failures by using multiple, highly secure, encrypted data transmission paths. With one receiver the control room is able to provide multiple high security services including industrial GPRS monitoring networks as well as such services as Securitel and Asset Tracking.
How it Works;
Security systems are able to use multiple data delivery methods and when used collectively, or more accurately, as primary, secondary and tertiary redundant paths they form the highest level of redundancy monitoring ever seen in Australia.
The SG2 Receiver uses three main redundancy paths on a networking level for data transmission and delivery,
• Path 1 – Primary: VPN (Virtual Private Network).
• Path 2 – Secondary: GPRS (General Packet Radio Service)
• Path 3 – Tertiary: Satellite (Optional).
Redundancy;
On a systems level the SG2 utilises the data delivery solution Intelipath. In the event of line failure Intelipath automatically re-directs all alarm traffic and data transmissions via the multiple encrypted redundancy paths. Using this delivery method, the SG2 can take care of Control Room data communication failures, including PSTN failure and Receiver failure.
