Installing a home security system is an effective way to protect your property and loved ones. Many modern systems are wireless and designed for easy do-it-yourself installation. This guide walks you through setting up your own security system. You can follow along with Kevin O’Connor from This Old House as he installs a wireless alarm system in the video above.

Components of a DIY Security System

A DIY security system typically includes the following components.

Base Station

The base station serves as the central hub of your security system. It communicates with all other components and often includes a built-in siren. Here are some tips for choosing a location for your base station:

• Select a central area of your home.
• Make sure it’s within range of your Wi-Fi router.
• Place it near an electrical outlet for power.

Entry Sensors

Entry sensors detect unauthorized access through doors and windows. These sensors consist of two parts: a magnet and a sensor containing a battery. When installing entry sensors, keep the following in mind:

• Place the sensor on the door or window frame.
• Attach the magnet to the moving part of the door or window.
• Check that the two pieces align when the door or window is closed.

Motion Detectors

Motion detectors add an extra layer of security by sensing movement within a specific area. Follow these guidelines when installing your motion detectors:

• Place them in high-traffic areas or entry points.
• Mount them at a height of 6–8 feet for better coverage.
• Avoid pointing them at heat sources or windows to prevent false alarms.

Control Panel or Keypad

The control panel or keypad allows you to arm and disarm your system. When choosing where to put the control panel, follow this advice:

• Choose a location near your main entry point.
• Make sure it’s easily accessible for quick arming and disarming.
• Mount it at a comfortable height for all household members.

Security System Installation Process

Installing a DIY security system is a straightforward process that most homeowners can complete in a few hours. Follow these steps to set up your system:

1. Unpack and organize all components.
2. Install the base station in a central location.
3. Mount entry sensors on doors and windows.
4. Place motion detectors in strategic locations.
5. Install the control panel or keypad near the main entry.
6. Set up additional components such as cameras or smoke detectors.
7. Connect the system to your home’s Wi-Fi network.
8. Test all components for proper functionality.

Programming and Testing Your Security System

Once all components are installed, program and test your security system with these steps:

1. Follow the manufacturer’s instructions to set up user codes.
2. Program emergency contact information.
3. Configure notification settings for your smartphone.
4. Test each component individually for proper functionality.
5. Perform a full system test by arming and triggering the alarm.

Enhancing Security with Environmental Sensors

Environmental sensors further protect your home from potential damage caused by environmental factors. Here are some types of sensors you can install:

• Glass break sensors: These sensors detect the sound of breaking glass and trigger the alarm. They effectively deter intruders who attempt to bypass entry sensors by breaking windows. Place them near windows or glass doors. Make sure they cover the maximum area for the best results.
• Temperature sensors: Temperature sensors can alert you to extreme temperature changes that might indicate a fire or HVAC failure. Place them in areas where temperature fluctuations can cause significant damage, such as near furnaces or freezers.
• Water leak sensors: These sensors notify you of potential leaks and water damage. They are especially useful in areas prone to flooding or leaks. Place sensors near water heaters, sinks, or basements. Connect them to the main security system for instant alerts.

Additional Security Features

To enhance your home’s security, consider adding these components to your system:

Security Cameras

Wireless security cameras allow you to monitor your property remotely. When installing cameras, keep these tips in mind:

• Place them at entry points and high-traffic areas.
• Give them a clear view of the desired area.
• Connect them to your home’s Wi-Fi network for remote access.

Smart Smoke and Carbon Monoxide Detectors

Many DIY security systems offer smart smoke and carbon monoxide detectors that integrate with the main system. These devices help alert you to fire and gas leaks.

Smart Door Locks

You can control smart door locks remotely and integrate them with your security system. They offer keyless entry options and can be programmed to lock automatically when you arm your system.

Smart Home Integration

Integrating your security system with other smart home devices can increase convenience and security. Consider integrating the following features.

Smart Lights

You can program smart lights to turn on and off at certain times or in response to specific actions. Here are some examples of ways you can use smart lights:

• Program lights to turn on when motion is detected.
• Program lights to turn on with certain voice commands.
• Schedule lights to turn on when you’re away to simulate occupancy.
• Sync lights to the sun, using cooler colors during the day and warmer ones in the evening.

Smart Garage Door Openers

Integrating a smart garage door opener with your security system allows you to monitor and control your garage door remotely. You can program it to close when you arm your security system and receive alerts when the door is left open.

Maintaining Your DIY Security System

To keep your security system functioning at its best, follow these maintenance steps:

• Clean camera lenses and sensors periodically to maintain performance.
• Regularly check and replace batteries in wireless components.
• Test the system monthly to make sure all components are working correctly.
• Update the system’s software when prompted.
