In the year 2015, the number of crime cases in the city of Mumbai was a whopping 42,940. You realize these numbers could easily become the numbers in your hometown as well, and fear for the safety of your home and loved ones. Therefore, you decide that a smart security system would be best. However, your town lacks a stable WiFi connection, and this in turn would hinder the functioning of your smart security system. Lucky for you, with a GSM-based security system, you won’t have to rely on a WiFi connection to make sure your home’s safe— all you’ll need is a GSM SIM card a security device that supports one!


Wait, what’s GSM?

GSM is basically a communication protocol, or frequency, on which our cell phones work. Remember a time when there used to be GSM and CDMA based phones? Well, GSM is now mainstream and is used by almost all mobile devices. So the SIM card you get from your telecom operator is a GSM one (besides those CDMA devices which are sort of being phased out by most telecom operators) . Besides your phone, this SIM card can go into other devices, such as security systems.


What’s a GSM Security System?

Simply put, the GSM-based security system uses cellular as well as data networks including 2G, 3G and 4G LTE via a GSM SIM card to alert you (with an SMS and phone call) in case of any sort of intrusion in your home— they’re pretty convenient in places with zero Internet connectivity.


Here’s more about why GSM-based  security systems are so convenient:


Never miss a single alert!

Since these types of security systems function with SIM cards, you’ll receive a phone call, as well as an SMS if there’s been an intrusion in your home, so you won’t have to rely on an app, which uses the Internet to work.

GSM security alerts on a smartphone

Receive every security alert via a text message or phone call with a GSM-based security system.


View live video streams of your home

Away on a vacation but find yourself worried about your home? Relax! GSM security systems allow you to view a live video stream of your home. They aren’t limited to just screenshots and alerts, you know. By being able to view a live video stream of your home, you can make sure everything’s in order. You can check whether your domestic help is doing a proper job, and can also make sure they’ve closed every door and window in your home before leaving.


24/7 monitoring

Worried about days when your Wi-Fi is down, thus being an obstacle to your home’s security? Well, worry no more. As these security systems don’t rely on a Wi-Fi connection, you’re guaranteed 24/7 monitoring, as well as security alerts, that’ll you’ll receive via a text and phone call.


It’s variety of peripherals like:

  • Security cameras: These are the most common peripherals of GSM-based security systems. Security cameras are the ones that record video footage of intruders, as well as let you view a live stream of your home through them.
  • PIR Motion Sensors: Passive Infrared, or, PIR motion sensors, are able to detect unsolicited movement in your home— even in the dark. With their ability to detect occupancy, intrusions, and movement in general, these smart sensors are vital to your GSM-based security system so that you are notified when there’s been an intrusion in your home.
  • Fire and smoke alarms: Fires cause major damage when they’ve been attended to late. So why risk your home being torn down by a fire? Certain fire and smoke alarms can also be GSM-based, and so, in case of a fire, you’ll be called, as well as texted immediately.


The peripherals aren’t limited to the above, however. Other peripherals available include wireless sirens, as well as door and window sensors.

Here are a couple GSM-based security system brands to consider investing in:

  • D3D Security: This brand offers a wide range of GSM-based security devices such as fire alarms, burglar alarms, sirens, PIR motion sensors and more, and are also quite a popular choice in the Indian market.
  • Arduino: Arduino, that also specializes in IoT software, is also quite a popular brand when it comes to GSM security systems. This brand too, offers a wide range of GSM-based security devices for homes.


GSM-based security systems are therefore one of the most reliable solutions in zero-internet zones when it comes to keeping your home safe. Especially in India, where Wi-Fi connections are quite unreliable, these types of security systems come to your rescue, by solely depending on a GSM SIM card, that’s easily available. Additionally, by receiving texts and a phone call in case of an intrusion, or a possible fire, you won’t have to depend on an internet enabled phone either, no matter where you are.
