If you're in the market for a DIY security system, you'll likely find that contact sensors come with nearly every kit, regardless of brand or size. Learn more about why contact sensors are included in most modern home security systems and how they help provide you with an extra layer of protection.
Understanding How Contact Sensors Work
First things first — before we dive into learning more about contact sensors, let’s get a better understanding of how they work.
The most common type of contact sensor has two distinct parts: a reed switch and a magnet. If someone opens a door or window when your alarm is armed, for example, the two parts separate, breaking the circuit that triggers your alarm system and will send a signal to the control box. If you subscribe to Ring’s professional monitoring services, the center is notified immediately.
The Difference Between Window and Door Contact Sensors
Window and door sensors work in similar ways. Many security providers offer a single model that can be used for both, while others have slightly different options. Door sensors are typically attached to the door frame and the door itself, with a sensor on each side. Window sensors usually consist of two parts as well; one part of the sensor is placed on the window frame, and the other is installed on the pane.
Common Types of Door Sensors for Alarm Systems
You can use contact sensors to secure practically any type of door in your home — but some doors require a specific type of sensor:
Choosing Where to Place Door Sensors
While you can install sensors on nearly any kind of door, it’s a good idea to start with your home’s most visible entry point — the front door. Once it’s secure, you can place sensors on all of your ground-floor doors, since they’re the most vulnerable to unwanted visitors. As your needs change, you can add more sensors in additional locations to enhance your home security system.
Where to Install Window Sensors
Like doors on your home’s ground floor, windows on the lower level are also the easiest entry point to access, so it’s a good idea to start there and work your way up. Window contact sensors only work on windows that open, so don’t worry about installing sensors on any non-opening windows. If you’re concerned about leaving them vulnerable to an unwanted visitor, you can secure and monitor non-opening windows in your home with glass break sensors.
Other Benefits of Contact Sensors
Contact sensors are a great way to protect your home, but that's not all they can do!
Secure Easily Accessible Items and Valuables
Sensors can also be used to secure storage spaces such as cabinets and jewelry boxes. By placing a sensor on the access points to these items, can help you track if anyone is getting into them without your permission. If someone tries to access your valuables, you’ll be notified.1
Keep an Eye on Entry Points of Your Home
Ring Alarm Contact Sensors provide an extra layer of security, allowing you to know when a door or window is opened so you can take action. You can set up real time notifications to get sent to your phone from the Ring app, in addition to being able to hear the contact censor chirp.2 Our sensors can easily be mounted to any door or window frame in your home for an easy DIY installation process.
A Unique Window Sensor Accessory
Contact sensors that come with Ring Alarm Kits can be used on windows and doors, but we also offer a separate accessory specifically designed to enhance the way you secure the windows in your home. Leave sliding doors and windows cracked open for ventilation and still have security with the Ring Open Window Magnet for Ring Alarm. It allows you to install an additional contact point that easily mounts to any window frame, so you can feel secure even when the windows are open.
Now that you have a better understanding of how contact sensors work together with your security system, you’re better equipped to help keep your home, family, and neighborhood safe.
