Workings of GSM signalling
A GSM alarm is a piece of security equipment that uses mobile communication—specifically, sending a signal to a smartphone—to alert the object’s owner to unwanted acts. Using the digital GSM mobile cellular communication standard, GSM signalling data is transferred.
The GSM signalling protocol’s basic working principle
You must comprehend how the GSM alarm system functions before deciding on this security solution. This rather straightforward device has a central unit or panel that has a GSM module and motion sensors. You can connect wireless sensors for gas and smoke, breaking glass, and unlocking in addition to the control panel.
Security systems provide an SMS-formatted alarm signal directly to the property owner’s mobile phone. With the help of the system’s many setup modes, it is possible to set up alerts for fire, object penetration, and gas leaking, and the messages will be sent simultaneously to several recipients from a list that has been generated in advance. A siren is turned on in the room at the same moment. Until a return (acceptance) signal is sent, the alarm will continue to ring. It is possible to configure each zone in the room for a unique signal, making it easy to pinpoint exactly where the device was triggered.
The owner can independently call the police or the rescue service after receiving an alert signal. Homes, flats, small businesses, cottages, workplaces, and retail spaces frequently have these security systems installed. Mobile phones are used to remotely manage some systems. The main GSM alarm unit only has a few features. When purchasing equipment, it is important to consider the size of the object because it is attached to a particular number of sensors.
Modern technology allows the system to function in accordance with the following principle:
- Only let the owner know. To 1 to 10 recipients, such as family members, the director, the security control panel, and other services, messages are conveyed. Everything depends on the danger.
- If, for instance, there is a fire or smoke, the siren is activated, or the evacuation exits are illuminated, turn on a mass notification.
- Include defence and additional systems. The ventilation system, fire extinguishers, gas supply, and water supply are all controlled via GSM signalling. The security system immediately turns off everything if there is a water leak.
The excellent functionality of such tools makes it possible to completely safeguard any piece of real estate.
What components make up the GSM security system
- Control panel serving as the security system’s brain. Here is where the sensor data is transmitted. All the data is evaluated in the main module, following which the warning signal is generated by the device.
- Control elements that allow you to regulate how the equipment operates. Typically, this is a cell phone or a radio key fob (in more advanced models).
- Room-wide sensors that can see and hear everything. They are the ones who send all the data to the main module.
- Alerts (siren or other elements). In some cases, the owner will suffice to alert the security station or the mobile phone.
The GSM security system’s benefits
It is simpler to understand the benefits of these gadgets for individuals who are familiar with how an alarm functions using a GSM module:
- Dependability. The possibility of signal interception is greatly decreased because all data sent to the central unit is encoded.
- Further functionality. There are models that can connect to a “smart house” system to start the heating and climate management.
- Maintains and safeguards property. Simple settings. Such an alarm system can safeguard not only real estate, but also a car and a safe where valuables are kept.
- It’s really easy to install a GSM alarm system; you only need to follow the instructions.
- Possession of any object. It is possible to keep an eye on the company’s employees, as well as the behaviour of nannies and other staff members, if all the sensors are installed correctly.
- A large area of effect due to the inclusion of an additional amplifier.
The potential for autonomous operation (from lithium batteries, accumulators). When a wired security system cannot be installed, this option may be used.
GSM signalling classification
Leading suppliers provide both wireless and wired security systems, which are comparable. To choose the right equipment, it is vital to understand both of these categories.
Wires are used to link the receivers to the main unit. These types are affordable, but connecting wires must be laid for them to operate normally. This entails a significant amount of building and installation work, and the cost will be on par with wireless systems.
The wires make it challenging to maintain the system and are simple to cut, rendering the security apparatus useless. Additionally, wired sensors use more power, but you can save on batteries by using them instead of wireless devices.
Even though these alarms are more expensive, they have the major advantage of not requiring installation. They are simple to install and keep up. Since no one can cut the wires and remove the safeguards, they are also more dependable.
If you get a model with an Internet module, you can learn what is occurring in the workplace, flat, or other location. The owner receives an SMS message with a picture or a video if there has been penetration. The owner can then call the police once it is known if a person or an animal set off the alarm.
The intensity of the signal transmitted to the sensors must be considered while selecting a wireless system. There is a chance that the signal won’t reach the owner in a timely manner if there are several walls between them and the GSM module. Their usage of batteries that discharge for electricity is one of the drawbacks.
Wireless models fall under a separate classification as well. They are broken down into:
- PRO stands for professionally installed and linked equipment. Such equipment is backed by quality certificates that attest to its ability to protect any object. They could be shown on the main console as well. While maintaining these systems is not difficult, it is challenging to quiet them, and the communication quality is much better.
- DIY equipment is something which can be quickly installed by the user. These models do not offer as much protection, though. It is simpler to shatter them, quiet them, and sabotage the line of communication. Direct connections to the security panel are not possible.
- Hybrids are cutting-edge devices that mix the PRO and DIY market sectors. They were inspired by these segments and adopted their rich settings, control system, and easy installation. Remote software updates are available for the system. They borrowed dependability, good protection, and no nutritional issues from PRO. These devices typically include an extra battery, jamming protection, and an extra channel for the GSM signal to be transmitted through.
