Smart Cameras: These are integral components of any home security system. They offer live video feed of your home which you can monitor remotely through an app on your smartphone. Some smart cameras also include motion detectors and the ability to record video, making them incredibly versatile.

Alarm Systems: These can be as simple as a siren that sounds when a door or window is opened without deactivating the system or as complex as a system that integrates with a professional monitoring service.

Sensors: Typically, there are three types of sensors used in home security systems: door/window sensors, motion sensors, and glass break sensors. Each has its own specific function and can be used individually or combined to create a comprehensive system.

Smart Hub: This is like the brain of your home security system, connecting and coordinating all the devices.

Ring Devices: These are smart doorbells equipped with cameras, offering you the ability to see and speak to whoever is at your front door.

Professional Monitoring Services: While not a device, this is an option you might consider. These services monitor your system and contact the authorities in case of a breach.

DIY vs. Professional Installation

After selecting devices, you need to decide on the method of installation. This section will provide insights into DIY and professional installation.

DIY Installation: DIY home security systems are becoming increasingly popular due to their affordability and flexibility. These systems often provide user-friendly instructions and require minimal tools for installation. You have complete control over where and how devices are installed, and you can easily modify your system as needed.

Professional Installation: While a professional installation comes with an added cost, it offers the benefit of a professional’s expertise. The system will be installed quickly and correctly, and many companies offer a warranty or service plan, providing peace of mind.

SimpliSafe: An Affordable and Versatile Option

SimpliSafe is a home security brand that offers affordable, no-contract plans and versatile, user-friendly devices. If you’re looking at an easy entry into DIY home security, SimpliSafe could be an ideal option.

The SimpliSafe system includes a variety of devices such as a base station (the hub), an entry sensor, a motion sensor, and a yard sign. Additional devices like a smart camera, smoke detector or extra sensors can be added on at an additional cost.

Monitoring Apps and Software

Once your system is set up, you’ll need a way to monitor it. This is where home security apps and software come into play.

There’s a plethora of monitoring apps available, many of which are compatible with various smart devices. These apps allow you to monitor your home remotely, receive notifications of any suspicious activity, and even control your system remotely.

Smart Home Integration: If you have other smart devices in your home like a smart thermostat or lights, consider an app or software that integrates with these. This will enable all your devices to communicate with each other and create a comprehensive smart home ecosystem.

Create a Backup Plan

While a smart home security system can go a long way in protecting your home, it’s essential to have a backup plan. This could involve integrating your system with a professional monitoring service or setting up a network of trusted neighbors to keep an eye out. Your plan should also include regular maintenance checks on your system to ensure everything is working correctly.

Building a low-cost smart home security system requires careful planning and research, but the result is a personalized, effective solution tailored to your needs. Consider your options carefully, and remember that the best security system is one that provides peace of mind without breaking the bank.

Smart Home Integration

Smart home integration is the process of linking different smart devices, such as your home security systems, with other home devices. This process allows all your smart devices to communicate with each other, creating a unified smart home ecosystem. Examples of other smart home devices include smart thermostats, smart lighting systems, smart doorbells like the ring alarm, and smart speakers like Amazon Alexa or Google Home.

This integration can offer additional security benefits. For example, if your security system detects an intruder, it could automatically lock all the doors in your home, switch on all the lights, or even play loud music or sound an alarm to scare off the intruder.

To achieve this, you need a base station or a hub that links all these devices. Some popular options include Abode smart, which is compatible with most major smart home brands.

In addition, consider using an app or software that allows you to control all your devices from one place. These apps usually offer features like live video streaming, real-time notifications, remote control of devices, and even the ability to set routines and schedules for your devices.

It is essential to note that not all devices may be compatible with each other. Thus, when choosing your home security systems and other smart home devices, ensure they can work together seamlessly.


Building a low-cost smart home security system can be a rewarding and cost-effective venture. It not only provides you with a sense of security but also gives you better control over the safety of your home.

Remember to carefully consider your specific needs when choosing the devices to include in your system. Whether it’s smart cameras, alarm systems, sensors, or a ring alarm, each comes with its unique features that add to the overall effectiveness of your security system.

When it comes to installation, both DIY and professional installations have their pros and cons. DIY installation gives you more control and can be more cost-effective, while professional installation ensures your system is set up correctly.

Including smart home integration in your plan allows for a more comprehensive security approach. Through this, you can link your security system with other smart home devices, creating a more secure and personalized environment.

And finally, always have a backup plan. This could be through professional monitoring services or a network of trusted neighbors. Regular maintenance checks are also crucial to ensure your system is always up and running.

In the end, the best DIY home security system is one that suits your needs and provides you with peace of mind, all without breaking the bank.
