DIY Security Systems That Protect Your Home on the Cheap

May 16, 2018 |

Whether you’re a techie or a novice at home automation, we’ll offer options to install your own home security system at a price you can afford.

Previously, building out your own affordable home security system was a pretty ambitious endeavor. Translation? Non-techie types need not apply. But times and technology have changed. These days, securing your home doesn’t have to be a big, expensive commitment involving extensive wiring and many, many YouTube videos.

Today’s DIY approaches are straightforward, wireless, and able to integrate home automation in unprecedented ways that even novices can manage. Before you decide that do-it-yourself security is the answer, let’s discuss how a home security system works and what components can make the difference during a break-in.

How Do Home Security Systems Work?

Home security systems generally have two main features: surveillance devices and sensors that trigger alarms. These include various components like security cameras, alarms, and door or window sensors that are connected through a central hub allowing users to control and respond to incidents.

Compatible Devices that Communicate Wirelessly

While you could have these elements hardwired to a phone line or cable connection, that’s an old-school approach that most security experts advise is easily sidestepped by thieves. One strategic cut and your alarm system is off-line and your home exposed, especially if you’ve opted to forego the professional monitoring. To alleviate that concern, we focus on affordable components and systems that allow home owners to connect and monitor wirelessly.

But with that convenience comes a new challenge. Your components need to be compatible with each other. Choosing cameras, alarms, and sensors that employ the same communication protocols is vital for a working, fully integrated home security system. For a more in-depth discussion of two communication protocols, ZigBee and Z-Wave, visit our ZigBee vs. Z-Wave comparison article.

The bottom line? ZigBee gives you more flexibility, but Z-Wave is easier to use and has more security industry support. For that reason, most of the recommendations we’ll make for home security components will rely upon Z-Wave technology.

Monitoring

Professional monitoring is both the advantage and disadvantage of DIY home security systems. While you can get away cheap by self-monitoring and managing the components yourself, this method also puts you in charge of responding to incidents. Rather than automatically deploying police to your home, your security system will simply alert you and allow you to decide whether to act. During a break-in, delays in responsiveness can be crucial to property loss and damage.

While you might start out monitoring your own security system, it would be wise eventually to employ professional monitoring for more convenient management of alerts and alarms. While some security companies insist that you use their brand devices to sign up for their monitoring services, a few support customers who buy and install their own devices.

Components of a Home Security System

What goes into a security system? The perfect recipe for protecting your home depends on balancing how much you can invest with the protection you need. At a minimum, you want to choose devices that are multifunctional, wireless, able to communicate well with each other, and flexible enough to expand the system affordably. You’ll see some variation of the following components in our recommended packages.

  • Control Panel or Hub: This device acts like the brain or command center of your home security system, receiving signals from various components and providing alerts and status updates.
  • Door and Window Sensors: These relatively inexpensive sensors can be attached to doors, windows, and more to detect disruption, breakage, or vibration should someone attempt to enter your home.

See SafeWise’s Top 5 Self-Install Door and Window Sensors.

  • Security Cameras: Both indoor and outdoor cameras can be incorporated into a home security system to provide surveillance on the property and alert you to intruders.

  • Motion Sensors: Sensors installed inside your home alert the system to suspicious movements and can be used to confirm activity from other security devices.

Get more information about how to effectively install motion sensors.

  • Siren or Alarm: These devices are typically rigged to emit screeching, ear-splitting noise in the event of a break-in and scare away potential thieves.
  • Yard Signs and Stickers: Sometimes, it’s simply the evidence of a system, provided by signs and stickers, that effectively discourages a robbery.

How effective are security signs? SafeWise investigates.

  • Monitoring Services: Professional security companies provide 24/7 monitoring services so that they can keep tabs on your security system, disable false alarms, and deploy police to your home quickly during an incident.

Unmonitored and monitored security systems. What’s the difference?

  • Key Fobs: These convenient little gems attach to your keychain and allow you to disarm or engage the system remotely, much like a garage door opener.

What is a key fob? SafeWise knows.

  • Integrated App: You’ll need a place to view updates from your hub and manage cameras, alarms, and other connected devices. Most security device manufacturers have an app that allows you to do this and syncs with your mobile device.

Building Your Own DIY Security System

Go Minimal for Under $100

You get what you pay for, and in this case it’s not much.

If you’ve only got a few bucks to spend, you can take some basic steps toward installing an affordable home security system, but you won’t have the bandwidth to buy a hub. That’ll leave you managing any components independently, so we focused here on multifunctional devices that offer surveillance and the appearance of security. It’s the fake-it-until-you-make-it approach.

  • Yard Signs and Stickers: $20
  • Outdoor Security Camera: $35.00

SafeWise recommends: Zmodo Outdoor Wireless Security Camera

  • Indoor Security Camera: $39.99

SafeWise recommends: Zmodo Wireless Indoor Camera

  • Cloud Storage for Video Surveillance: $5–$10 per month

See our recommendations for the best cheap home security cameras.

What You Get: Video surveillance, the appearance of a security system, and the ability to view video online. You will, however, have to pay a nominal fee (about $5 a month) to store it in the Cloud. Essentially, you’ll be able to see what’s going on at your front door and inside your living room. You just won’t be able to do anything about it.

A Touch of Tech for Under $200

You don’t need to be a smarty-pants to start securing your home with Samsung’s SmartThings.

If you can splurge just a little bit, you’ll be able to start things out right with an affordable smart hub. This unit is the brain that controls the network of connected devices that manage not just your home security, but also your home automation devices like lights, thermostats, and more.

  • Control Hub: $89.99

SafeWise recommends: Samsung SmartThings Hub, 2nd Generation

  • Yard Signs and Stickers: $20
  • Door Multi-Purpose Sensor: $35.99

  • One Motion Sensor: $35.99

What You Get: SmartThings is a system you can expand to integrate with other home automation devices, including cameras. Add on sensors and alarms later without concern since Samsung has adapted SmartThings to work with a wide range of other devices. SmartThings also has a free app to help you manage all your home automation in one place.

You won’t, however, get the option for video or professional monitoring since you’ll be shelling out up front for the hub. Good things, or SmartThings as it were, come to those who wait.

See our review of Samsung’s SmartThings system for more information.
