How Does GSM Security System Works
Nowadays, all of us are concerned about safety. Why nowadays, most of us who live with our families have always been concerned about safety. It is not enough that we live in brick and concrete houses with padlocks and bolts; we also need to ensure that the house and our possessions are safe when we leave them to go out. This is where excellent alarm systems come into the picture! A good alarm system does just that – it alarms us or rather raises the alarm whenever someone breaks into our house or safe to steal our possessions. In the e-enabled age that we live in, things have gone the digital way. The same is the case with alarm systems. Nearly every alarm system that is available in the market now is a digital alarm system, such as GSM security system. And just as nearly every aspect of our life having gone the digital way, this too is likely to remain. So how does a GSM security system work? And how exactly is it different from mechanical alarms? Is a GSM security system safe? What is GSM? GSM stands for Global System for Mobile Communications, which is basically the mobile phone network as we know it. It is a worldwide standard, operating in more than 170 countries and supports not just voice communications but also text messaging and data transfer.
An alarm system can work with different sensors or alarm accessories, and it usually has auto-dial or sms features. When a sensor (eg. door sensor) or an accessory (panic button) triggeres the alarm, the alarm system can activate the siren (if installed) to give out loud sound and then auto-dial to the pre-set phone numbers / call center to notify the alarm event. The alarm can also send sms notifcation to the pre-set phone numbers to report details of the alarm event.
A basic alarm system usually consists of the following devices:
1. Alarm host: The central unit of the alarm system which is connected to phone line or has GSM connection. Alarm setups can be customized by user or installation company. User can control arm or disarm status with the alarm host. The alarm host can send out signals to siren, make auto-call, or send sms notifications to alert the user, call center, or neighbour about the alarm event.
2. Keypad or remote control: You can arm, disarm, or trigger emergency panic with the use of keypad or remote control. With the use of keypad and remote controls, the user can store the alarm host in a private secure place and operate the alarm host with the keypad and remote controls instead.
3. Siren: During an alarm event, the siren receives signal from alarm host and give out loud sound. Some siren models also provide stobe light feature. This can help warning the intruder to leave the property and also notifying any person in the property (for partial arm use) or neighbours.
4. Motion detector: It can detect human presence within the detectiong range. When motion is detected, the device emits a signal to the alarm main unit to set off the alarm.
5. Door sensor: It can detect opening or closing of any door or window. When sensor is triggered, the device emits a signal to the alarm main unit to set off the alarm.
6. Smoke detector: It is used for fire detection triggered by particles in smoke. When smoke is detected, most smoke detector models can give out loud sound and LED light indication, and send a signal to the alarm unit to set off the alarm.
There are many different kinds of sensors that can be added to the alarm system: panic button, glass break shock sensor, IR beam detector, gas detector, etc.
