Frequently Asked Questions

What are door sensors?

A door alarm (also called a door sensor) is an essential part of a home security system to keep your home safe. A door sensor keeps track of whether a door is open or closed. These alarms alert you audibly and/or with a text notification when a door has been opened (depending on your settings). With a door alarm, you can know that your home is secure and that no one is coming or going without your knowledge. The same technology used for door sensors can also be used on windows. This technology is simple, reliable, and affordable, making it ideal for DIY home security systems.

How does a wireless door alarm sensor work?

The sensor itself is a two-piece device. One part of the wireless door alarm is attached to the edge of the door, and the other part is attached to the door frame. Both parts are mounted with an adhesive strip. The two pieces are parallel with one another, almost touching. When the door is opened, it breaks the invisible connection between the two parts of the sensor, tripping the alarm.

To elaborate, one part of the sensor has a magnet inside, and the other part contains a magnetically sensitive trigger called a "reed switch." The reed switch houses two magnetic wires that are prevented from completing a circuit when its sister piece is next to it. When the part of the door sensor that contains the magnet moves away from the other half of the sensor, the two wires of the reed switch are able to touch, which triggers a signal to your Cove Touch Alarm Panel.

What type of sensor is best?

We recommend wireless door sensors because of their simplicity, reliability, and customization. Cove uses wireless sensors because their wired counterparts are quickly becoming outdated. The hassle involved in installing wired alarm systems usually requires many hours of setup time by a trained professional. This can be an expensive nuisance. Additionally, wired systems are often more conspicuous and susceptible to failures or tampering.

How many security alarms for doors do I need?

Security systems for doors are essential to the safety of your home. We recommend sensors be installed in every possible access point to your home. You’ll want them installed on all doors and windows so that there is no way a thief, burglar, or home invader can enter your home without triggering an alarm. Door alarms and window sensors are essential to a complete home safety system. Sensors on any possible entry points keep you and your security monitoring service in the know about any potential threats so that you'll be protected.
