Pros And Cons Of GSM Home Alarm Systems in 2022


A GSM alarm system is also known as a landline-free or personal digital alarm. It operates precisely like any other personal alarm. It utilizes a multi-network SIM Card instead of a telephone line to contact the alarm monitoring center when the user hits their pendant button.

What is the mechanism of a GSM alarm?

A GSM home alarm operates the same way as a cell phone SIM but can connect to more than one mobile network. A GSM alarm’s multi-network SIM will connect with the best available network to provide continuous, dependable service. Switching between networks using the SIM card in the personal alarm is possible.

What Are The Benefits of Installing GSM Security Alarms In Your Home?

One trustworthy option for home protection is a GSM alarm system. Intruders attempting to disable your home security system won’t succeed if they focus on disrupting your electricity or telephone service. Even if you lose mobile service, your GSM security alarm will generally operate since it is still linked to the GSM network.


Additionally, GSM home security alarms are wireless devices. The setup of your GSM alarm will be simple and fast as a result. Because they don’t need extensive wiring to be run within the walls of your house, wireless home security systems may be installed wherever you choose.


Your new GSM alarm system is flexible, allowing you to place sensors anywhere you see most appropriate. The security alarm control panel, sensors, cameras, and sirens of a typical wireless home security system are all powered by batteries. Home security systems that run on batteries make it simple to maintain constant power and functionality to prevent breaches in safety.

On top of all that, you may be able to set up your wireless home security system without hiring a professional. Don’t worry about the high expense of setup! A wireless GSM home security system is an excellent choice if you often change residences (whether you rent or own them) because of its freedom to carry your security setup.


You may locate a home base for your alarm system anywhere you choose. When using a GSM alarm, you may put the GSM auto-dialer base unit anywhere. A “classic” analog warning requires proximity to a telephone jack since the operators must wire it to a landline. In contrast, a GSM alarm system is not limited in this way. As long as you have a fine cell signal, you may install the base unit anywhere you’d want it, for example, in a room or kitchen.

4-No Manual Call Picking 

If you don’t have a landline phone available at your residence, a personal alarm that uses a SIM card is the next best thing. There has been a rise in the number of individuals who use their mobile phones exclusively for making and receiving phone calls because they choose to avoid paying line rentals for a landline. You won’t have to pay the cost of installing a fixed line to use a digital GSM alarm; it will function like our regular personal alarm. You may have a whole home security system without needing a landline by combining our alarm kit with our wireless smoke detectors.

5-GSM alarm guarantees Protection

Since a GSM personal alarm doesn’t require an analog telephone network, it will continue to operate even after phone companies switch to digital infrastructure. Telecommunications companies are finding it more and more challenging to support the aging public switched telephone network (PSTN) that relies on analog calls.

Telephone companies may upgrade their services and better meet the needs of their customers by switching to Voice Over Internet Protocol (VoIP) instead. Phone companies have varying strategies and timelines for transitioning from analog phone lines. By 2025, companies want to move their subscribers to digital networks. Your cell phone service provider should be able to provide you with more information about their programs.

6-Inhibitor of Criminal Activity

Commonly included with home alarm systems are yard signs and window decals to let others know that your house is secured. Even if no additional security measures are in place, just seeing this warning may deter would-be intruders. Make sure the stickers and notices provided by your monitoring service are prominently displayed.

7-Reduced Premiums for Health Insurance

Putting up a home alarm system might be expensive, but it may save you money in the long run. It might reduce your homeowner’s insurance premium if you install a security system. Having an alarm system and, in many situations, a fire alarm may reduce the likelihood of expensive incidents resulting in a claim. Your insurance company can then reduce your premium.

Where do GSM home alarm systems fall short?

The SIM card in your phone is similar to the one used by GSM alarm systems, and both are used to send an alert to the authorities. Therefore, similar to a SIM card in a mobile phone, you will need to pay a monthly fee to maintain your home security system connected to the cellular network.


When budgeting for a GSM home security system, remember that it will be in addition to the usual security setup (alarm control panel, motion detection sensors, security cameras, door and window opening sensors, etc.).

2-Network Issues

The signal from a GSM home security alarm may be disrupted by a cellular network jamming device, which burglars have used in the past. Given that your GSM alarm relies on the mobile network to function, it will be rendered useless if any would-be burglars can disrupt that network.

Do not mistake a PSTN (Public Switched Telephone Network) home security system with a Global System for Mobile (GSM) alert. On the other hand, PSTN alarms utilize your landline connection to sound the alarm.

3-False Alarms

Even though a home alarm system might make you feel safer, it also irritates you. Your system will often trigger false alerts. Before you can clarify the error to your security provider, it may send the police or fire brigade to your house. Certain agencies may assess a fee if the police are summoned to your home frequently for no apparent cause. Ask your alarm provider about the potential causes of false alerts so you can disable them.
