Searching for tools to guarantee home security is increasingly important for many families, who are aware of the need to ensure the protection of their property and loved ones.
However, it can be greatly complicated given thenumber of options offered by the market, since technology advances very quickly.
One of the possibilities is to install a volumetric detector, although before doing so you should know what it is, how it works, and if it is really worth investing in it for home security.
Next, we explain everything you need to know about volumetric detectors.
What is a volumetric detector
As its name indicates, This is a device that detects the volume , although its operation is somewhat more complex than this.
The concept of volumetric detector serves to describe a set of sensors that can function in different ways, but that have theability to specify the volume of an object.
These sensors can be programmed to notify the alarm by detecting specific characteristics regarding the volume, which serves to filter the warnings and prevent false alarms.
In this sense, they can be a good option for the home, although before deciding it is worth knowing more about how they work.
How volumetric detectors work
As with all types of sensors, these can bemore or less precise. Generally speaking, a volumetric detector activates with movement , with the difference that it is capable of determining the volume of the body it is detecting.
A normal motion sensor would only detect the activity of the object. Therefore, the sensors They are placed at different strategic points of the space you want to monitor, thus creating perimeter surveillance.
When one or more of these sensors notice movement, are activated, sending a signal to the alarm to which they are connected. Depending on the type of alarm we are talking about, this It will be activated directly, or it will send a signal to the Alarm Receiving Center (AVE).
If you use a connected alarm, it will be the central staff who decide if the danger is real or if it is a false alarm, after which will notify the authorities Security camera with video analytics: is it worth it?
You may still have doubts about the differences between a volumetric detector and a conventional motion sensor. Why is it worth investing more in the first one?
Everything will depend, of course, on the level of protection you need. The main advantage of a volumetric detector is thatYou can program it to react only to the characteristics that you indicate..
This way, it would not jump at the movement of any target. The device will be prepared to warn only when "something" appears that, due to its volume, could constitute a real danger.
What types of volumetric detectors are there?
Precision is a key element when installing a volumetric detector, and this will depend, among other things, on the type of detector you decide to install.
There are different classes that are divided according to technology. through which they detect movement and specify the volume. Thus, there are four types of volumetric detector:
-
Infrared technology volumetric detector: Infrared technology can detect the temperature of a body, so the alarm would go off when it perceives a temperature very different from that of the environment.
Its main disadvantage is that the sensors are extremely sensitive to sudden changes in temperature. This may cause certain failures in some stations or environments.
- Microwave technology volumetric detector: These sensors work thanks to the Doppler effect, which means that they detect the waves that a body emits when moving near the sensor.
The fact that they are especially sensitive to movement makes them false alarms may occur frequently, which is why they are considered somewhat less effective than those with infrared technology.
- Outdoor Infrared Volumetric Detector: as their name indicates, they are also infrared technology. The difference they have is that they are more advanced thanks to a digital processor and two PIR channels. They are designed to better detect false alarms in environments where there is a lot of movement.
- Hybrid or mixed volumetric detector: combines infrared and microwave technology, so that it perceives both temperature and waves generated by movement.
Advantages of the volumetric detector: is it worth it for your home?
Among the advantages of volumetric detectors, the fact that they work thanks to movement and temperature stands out. Thanks to this They serve both day and night, unlike conventional surveillance cameras.
They are very effective when it comes to protecting both the interior of a home and its exterior. Furthermore, its advanced technology makes itare much more effective than other deviceswhen preventing certain dangers.
Their ability to determine the temperature of the space makes them also useful as a protection element in cases of fire, and not only to prevent a home invasion.
Considering all the features and advantages of these complex devices, it is clear that they have many benefits for home security.
However, false alarms They are perhaps one of the main problems to improve, especially considering that the fact that they jump continuously could lead to a fine.
For this reason, we consider that a volumetric detector at home is a worthwhile investment,in case you connect to a CRA, from which you can check in advance if the warning that appears is justified, or if it is a sensor failure.
In this case, we would avoid the problem of false alarms, making the protection of our home as precise as possible. With this and the volume sensing features of these devices, we can provide very complete security in our home.
