How To Install Your Own DIY Security System

Installing a DIY home security system is an affordable way to protect your home. With advancements in technology, these systems have become more accessible and user-friendly, allowing you to take charge of your security without relying on professional installation or costly monitoring services. In this article, we explore the process of installing your DIY security system, drawing insights from This Old House expert Ross Trethewey’s demonstration in the video above. 

Understanding DIY Security Systems

DIY security systems are a flexible and often more affordable alternative to traditional, professionally installed systems. These systems typically consist of a central hub, various sensors, cameras, and other smart devices that work together to monitor your home.

Components of a DIY Security System

A comprehensive DIY security system usually includes the following:

• Central hub or control panel
• Door and window sensors
• Environmental sensors (smoke, carbon monoxide, water leak)
• Mobile app for remote monitoring and control
• Motion detectors
• Security cameras (indoor and outdoor)
• Smart doorbell with camera

Benefits of DIY Installation

Installing your own security system comes with several advantages:

• Cost savings on installation and monitoring fees
• Easy relocation if you move
• Flexibility to customize and expand the system
• Integration with other smart home devices
• No long-term contracts

Preparing for Security System Installation

Before you begin installing your DIY security system, plan and prepare properly.

• Assessing your home’s layout: Walk through your home and identify primary entry points, high-traffic areas, vulnerable windows, ideal camera locations, and the best spot for your central hub.
• Choosing the right system: Choose a system that fits your needs and budget. Consider factors such as your home’s size, the number of entry points, your desired level of monitoring, compatibility with existing smart home devices, and cellular backup options for power outages.

Installing the Security System’s Central Hub

The central hub is the brain of your security system. Trethewey demonstrates how to install a central hub near the front door in the video.

Steps for Hub Installation

Here’s how to install most hubs: 

• Choose a location near your main entrance and a power outlet.
• Plug in the hub using the provided power adapter.
• Secure the plug with the included outlet cover to prevent accidental unplugging.
• Download the corresponding mobile app and scan the hub’s QR code to register it.

Setting Up Security Sensors and Detectors

Door and window sensors are central components of any security system. They alert you when entry points are breached.

Installing Door and Window Sensors

Follow these steps to install most door and window sensors: 

• Clean the surface where you’ll place the sensor.
• Remove the adhesive backing from the sensor.
• Attach the main part of the sensor to the door or window frame.
• Align and attach the magnetic piece to the door or window itself.
• Test the sensor by opening and closing the door or window.

Placing Motion Detectors

Motion detectors add an extra layer of security by monitoring movement within your home. Choose strategic locations such as hallways or large rooms, mount the detector at the recommended height (usually 6-8 feet), and aim the sensor away from heat sources and windows to avoid false alarms.

Installing Security Cameras

Security cameras provide visual monitoring and can deter potential intruders. Both indoor and outdoor cameras are demonstrated for effective home surveillance.

Outdoor Camera Installation

Here’s how to install an outdoor camera: 

• Choose a location with a clear view of entry points or vulnerable areas.
• Make sure the camera is within range of your Wi-Fi network.
• Mount the camera securely using the provided hardware.
• Connect the camera to a power source or install batteries if it’s wireless.
• Use the app to adjust settings and viewing angles.

Indoor Camera Setup

Below is how most indoor camera installations are completed: 

• Select areas that cover main living spaces or entry points.
• Plug in the camera and position it on a stable surface, or mount it to the wall.
• Use the app to configure settings like motion detection and night vision.

Setting Up a Smart Doorbell for Your Security System

A smart doorbell with a camera adds security to your main entrance. The process involves some electrical work but offers real-time video capabilities.

Installing a Smart Doorbell

Below is how to install a smart doorbell: 

• Turn off the power on your existing doorbell at the circuit breaker.
• Remove the old doorbell and disconnect the wires.
• Connect the wires to your new smart doorbell.
• Mount the doorbell using the provided mounting plate and screws.
• Restore power and follow the app instructions to complete the setup.

Configuring Your Security System

Once all components are installed, it’s time to set up your system for peak performance.

Setting Up Modes and Schedules

Create different modes such as “Home,” “Away,” and “Night” using the app. Set up schedules for automatic arming and disarming. Customize notifications for different events and sensors to suit your lifestyle.

Maintaining Your DIY Security System

Regular maintenance helps your system continue to function effectively and remain up-to-date.

Expanding Your System

As your needs change, improve your security setup by adding additional sensors or cameras, environmental sensors, home automation devices, and smart locks.

Routine Checks

• Clean camera lenses periodically
• Replace batteries in wireless devices as needed
• Test your system monthly
• Update software and firmware when available
