If you are looking to install an alarm system in your home, you will have to decide how many contact sensors you need. However, many homeowners are not familiar with contact sensors. You may not know what they are, what purpose they have and where you should place them. Getting answers to the questions you have about them will help you to learn what they are and how many you will need in your home. Here are some of the questions you may have about contact sensors and the answers.
What is a Contact Sensor?
A contact sensor is a two-part sensor. One part of the sensor is anchored onto a stationary object, while the other sensor is positioned on something that moves. When the part that moves moves off of the sensor on the stationary object, you are alerted. For example, one part of the sensor may be installed on the window sill and the other on the window. When the window lifts up from the window sill, the contact sensors are no longer in contact with each other and you are alerted.
Where Can Contact Sensors Be Installed?
Contact sensors can be installed in many different places in the home. They can be installed on your entry doors, your garage door, your bedroom doors, your windows and even on things like safes or drawers where you store jewelry, firearms or other valuable items. And contact sensors are not only used for home security. You can install contact sensors on your pool fencing or the cabinet doors where chemicals are stored to help alert you if a toddler is into something they should not be.
What Are the Benefits of a Contact Sensor?
The biggest benefit of a contact sensor is that you are alerted when the object you place it on moves in your home. Motion detectors have many limitations to them, and they are expensive to install. Contact sensors can pick up on motion that motion detectors cannot, and they are much cheaper than motion detectors. Contact sensors also have many uses beyond just security. You can see when your teenager comes home, monitor hazards to a toddler, or ensure your roommates don't enter your room and snoop around.
