Home Security Hardware Devices, Choosing The Ones You Need

Home Security Hardware: Choosing The Right Devices

The right home security hardware devices can help you establish solid home security. You need to choose the right sensors, contacts, and detectors.

There is a huge variety of home security products available to you.

There exists a home security hardware device for practically every security threat that you can image. Depending on your particular situation, they may not all be necessary.

As a general rule, start off with the basics and build your home security system slowly. Build it a little at a time until you reach a level of security that meets your security needs. A level that makes you feel safe and comfortable in your home.

Consider the following four home security hardware devices as your basics.

Think about them now, before you decide which do-it-yourself home security package to purchase. Decide how many of each you will need.


Door And Window Contacts – Typical do-it-yourself home security packages can include anywhere from 5 to 10 to 20 or more door/window contact sensors per kit.

Count the number of exterior doors and windows that you have. You’ll need contact sensors for each and keep in mind that every windowpane that opens requires a contact sensor.

If you have a sliding window for example, the two interior sliding windowpanes require one contact sensor each. You may therefore need two contacts per window depending on the type of windows you have.


Motion Detectors – A do-it-yourself home security packages will usually include 1 motion detector per kit. You may need one additional detector, depending on the setup of your home.

Motion detectors are typically installed in hallways and staircases or in any area that a burglar would have to walk through. People tend to get carried away with the number motion detects they need. Don’t get carried away. The average home requires 1- 2 detectors at the most.

You can buy more if you want to (or need to), but I recommend starting with the 1 motion detector that comes with the kit. If you have a pet, you can even get a pet-free motion detector that will ignore the movement of anything under 40 lbs.


Smoke Detectors – Smoke detectors are usually installed in the hallway close to the bedrooms. It’s also a good idea to have one smoke detector on every floor of your home.

Unfortunately, not all do-it-yourself home security packages include smoke detectors. You can contact your local fire department and find out how many your home requires according to the safety standards and by-laws of your district.

Be sure to include the required number of smoke detectors when purchasing your kit.


Carbon Monoxide Detectors – Carbon monoxide detectors are usually not part of a standard DIY home security kit. They’re home security products that you need to purchase separately.

You will need to install a minimum of one carbon monoxide detector per each floor of your home. Don’t forget to include the basement and any room containing a fuel burning devices (like a furnace or a gas water heater).

As always, first talk to your local fire department official regarding the carbon monoxide by-laws and regulations of your area. And of course, make sure that the detectors will work with the rest of your alarm system.

Other Home Security Devices To Consider – Always make sure that the alarm system’s central control panel or receiver allows for future upgrades so you’ll be able to add these devices later on.

After the basic four devices listed above, the next two devices you may want to consider installing are:

  • Glass break sensors
  • Heat detectors

They’re two additional home security devices for detecting both forced entry attempts and environmental dangers.

And possibly after that (if needed):

  • Additional Keypad (for secondary entrance)
  • Cellular Module (in case of phone line failure)
  • Outdoor Sirens and Strobe Lights
  • Temperature Sensors
  • Flood Water Sensors
  • Intercom System
  • Wireless Panic Buttons
  • Wireless Medical Alert Buttons
  • Combustible Gas Detectors

As was stated earlier, choosing the right home security hardware devices makes all the difference.
