The best security system means the one that works, and that keeps a homeowner safe and protected. Those aren’t necessarily hard to find, but there are some options that definitely work better than others. It can depend on a specific homeowner as to what they really want to see in their home security system. Of course, there are also plenty of options these homeowners have to choose from — and that can lead to confusion.

One of the areas where homeowners commonly get confused is in the difference between a door sensor and a motion sensor. These aren’t the same, but they are similar in some ways. That can lead to misunderstandings, and can mean that a home isn’t as protected as a homeowner thought it was. Making the right choice and getting the right kinds of sensors is very valuable when it comes to peace of mind.


What a Door Sensor Offers for a Homeowner

For a homeowner, a door sensor is designed to do just what they would expect — it lets the homeowner know when the door is opened. This can be a good way to monitor whether other people are going in or out of the house, but it can also be a good way to alert the homeowner if someone should force their way in where they shouldn’t be.

In short, a door sensor is designed specifically to detect the motion of the door, and not designed to focus on any other types of motion that may be seen around the doors, outside the home, or in the interior. With a very specific focus, the door sensor has one job that it must do.

Placed correctly, it will do that job very well. Placed incorrectly, and it can become problematic with false alarms. It also may not notify the homeowner the way it’s supposed to, which can also become a serious issue.

What is a Motion Sensor, and What Does it Do?

The right home security system is one that detects and also deters. With a motion sensor, the idea is to do both of those things. Often, motion sensors are tied to things like lights, alarms, or security cameras, so someone who may be thinking about breaking into a home will change their mind. Additionally, motion sensors can detect motion in a house, after someone has already broken in. That can trigger both alarms and cameras, in order to drive the person away and let authorities see what the person looked like. When choosing a motion sensor, a homeowner should consider:

  • the range of motion the sensor detects
  • whether it automatically triggers an alarm
  • whether it notifies the authorities and/or a smartphone app
  • if the sensor can trigger a camera or other type of recording device
  • the cost of the motion sensor versus the value it offers

With a good understanding of what a homeowner can get from a motion sensor, they can make the choice between that sensor and the door sensor.


Choosing a Security Company to Help with Sensors

Finding the right security company to help with motion sensors and door sensors is a good way to find out more information about both of those options and what they can truly provide. Most homeowners have both of these types of sensors in their security system, in different locations. Having both external and internal motion sensors, along with door sensors, is one of the best ways for any homeowner to get the true level of security and peace of mind they’re looking for.
