Although no one is exempt from being robbed, there are many security devices to protect your home and not make it easy for thieves. The motion sensor and the presence detector will help you make your home safer, but what are the differences between the two and which option is better?
Sensor or detector: what it is and characteristics
Sensor and detector are used interchangeably, since they both mean the same thing. Now, there are various types of sensors or detectors : for doors and windows, for smoke, motion and presence detection, etc.
In this article, we are going to focus on the main differences between the motion sensor and the presence detector . Although they do not have exactly the same use, they are often confused.
To begin with, this is the general definition of detector or sensor, whatever its function: it is a device capable of identifying any change in the place where it is placed. That is why it is so useful for prevent theft or send an alert immediately to the owner if there are intruders in the house. Even to notify the Police directly.
Another very important function, in addition to security , is that they help you save energy in your home. A clear example is the lights that turn off and on only when there are people in the room. Likewise, they offer a great comfort , since you will not have to locate the switch in the middle of the dark.
Before installing a motion sensor or presence detector, we advise you to take into account these characteristics of your home:
- The dimensions. First, you will need to have enough space to place a sensor or detector. This will depend on the type of device you want to install. Putting a motion sensor in the hallway is not the same as putting a smoke detector on the ceiling.
- The location. While you will have to place the motion sensor on the wall (at least two or three meters high to increase the viewing angle), you will have to install the presence detector (also called people detector) where you think people will pass by.
- The situation. It is also not the same to install this device in a private space, such as your home, than in a public space. This is also very important that you take into account, to know what type of sensor or detector suits you best . What exactly do you want to protect yourself from?
Differences between motion sensor and presence detector
Now that you know what exactly a detector or sensor is, what types there are or what you should take into account to install one at home, let's differentiate the motion sensor from the presence detector . They only have one thing in common: that both devices have a built-in timer.
Additionally, each device has some very specific functions. The motion sensor turns on and off when it detects heat from people and certain moving objects. When incorporated into a alarm or surveillance camera , they will capture that movement based on its field of vision or detection.
Timing
Both the presence detector and the motion sensor They are activated for a certain time . In this way, they can detect when an alteration occurs in the environment.
Sometimes what can happen is that they do not activate for too long. So you may believe that they do not work correctly. But in reality it is not like that. Here it must be taken into account that not all detectors or sensors They work the same.
On the other hand, it is not the same to place it in the hallway, in the bathroom or on the terrace. Maybe in some rooms you will end up finding it more convenient to use a manual switch to turn on the lights and in places like the entrance to your home If it is more necessary to install a motion sensor , to prevent theft.
First of all, you should evaluate the area and what type of sensor is best for you . If you are going to place one at home, consider what your needs are and look for a device that suits what you are looking for.
Sensitivity
Unlike the motion sensor, the presence detector is more sensitive to light or heat. In turn, the presence detector or people acts as a surveillance system, as it detects if someone is hanging around your house. The latter is activated when detecting infrared energy, emitting an alarm sound.
For his part, the motion sensor It is not able to detect the presence of people so easily. Unless the movements are very abrupt , clear. In that sense, you may be more interested in a presence detector to reinforce security inside your home.
Brightness
Light is another key factor when choosing between a motion sensor and a presence detector. Here, the luminosity detector It does not work as effectively on one device as on another.
On the one hand, the presence detector It constantly measures the amount of light in the environment, whether it is working or not. Instead, the motion sensor It's not as rigorous in that regard, since it can only measure light while it works.
These devices have become increasingly modernized and another of their objectives is to save energy throughout the day. Of course, as for the security that both devices offer at home, we assure you that both will give you the tranquility and comfort that you need.
