GSM & GPRS Wireless Security Systems Explained
Deciding whether to purchase a GSM or GPRS communicating security system is a relatively easy choice once you understand the differences. Here we explain the signicant differences.
GSM Security Systems
GSM security alarm systems are the most basic. Customers are required to supply their own mobile phone SIM card, which can either be Pay as you go or monthly / yearly contract (although contract SIMs are the most reliable as they never run out of credit).
GSM alarms are designed for users who only require activation alerts and status messages to be sent to between 1 - 10 mobile phones. These are ideal when system owners are based on or close to the site being protected and are happy that a simple text message is sufficient to alert them to an activation. Customers with higher security requirements or those needing a fully Alarm Receiving Centre monitored security system will require a GPRS security system.
The GSM alarm systems are programmed via a PC using a programming cable. Software is supplied on a CD or by downloading from our monitoring page.
GPRS Security Systems
GPRS security alarm systems are more complex and flexible than GSM security systems allowing them to be monitored via an Alarm Receiving Centre (ARC). These systems are supplied with a dedicated GPRS SIM card.
GPRS security systems are suitable for clients using multiple systems on multiple sites and/or those needing high levels of flexibility to cope with large numbers of people who require access to sites at different times.
Programming and Monitoring of GPRS Systems
GPRS based systems provide a two stage monitoring feature:
Each user is provided with secure access to our online portal. Each system can be viewed, programmed and armed / disarmed via the online portal, in real time, from anywhere in the world.
This is sufficient for users with their own control room, providing it is manned 24/7.
For users without their own control room, ARC monitoring is available via one of the UK’s largest accredited monitoring stations. Even if ARC monitoring is used, users can still monitor their systems in real time and make programming and arm / disarm changes via the secure online portal feature mentioned above. If an alarm activation occurs, the ARC staff will contact whoever you have designated on your keyholder list until they speak with someone.
