Modern devices in our homes are, first of all, convenience. A smart refrigerator will check what products are missing, and a wireless vacuum cleaner will remove dirt from the floor. In addition to the equipment, thanks to which you can spend less time at home and have more time for yourself, it is worth considering the purchase of a security system Сontrol.uathat allow you to feel safer. Among them, motion sensors and powerful systems for home video surveillance prevail.
Modification, that is, a system of motion sensors, is increasingly chosen not only by residents of houses, but also of apartments. This is one of the simplest and at the same time relatively inexpensive ways to deter potential robbers.
Active and passive motion detectors
Detectors, that is, otherwise, motion sensors, are divided into two categories - passive and active. How does the motion sensor work? Passive has the ability to detect changes in thermal radiation, which means that it can detect the movement of a person or animal and distinguish it from radiation transmitted through an object.
In the case of passive motion sensors, you should not overlook several points that can disrupt the operation of the device. The sensor cannot be located in the immediate vicinity of a heater, fireplace or other heat sources. The safe distance is 1,5 meters. In order for the detector to work without complaints, you should not place it near sources of water vapor, and also make sure that the light does not fall directly into the lens.
Active sensors detect electromagnetic waves. In the initial situation, the receivers of the waves are objects located within the range of the detector. A person (or an animal) that appears in this area leads to the fact that the frequency of the reflected wave changes, and the detector "catches" the movement. In order for the device to work in accordance with the rules, it should not be facing a window or balcony, so as not to accidentally detect movement outside the house or apartment. It is also important to install the sensor away from electronic devices, including the second sensor in the same room - the detectors can create interference and noise for each other.
The internal motion sensor is convenient for pet owners. The detector, after preliminary adjustment, may not detect animals up to 25 kg, so that residents are not afraid of false alarms caused by the entry of a pet into the room. This device is for those who want to feel safer in their home, and, at the same time, are afraid of complex installations.
How to connect a motion sensor?
It is enough to put the device on the furniture or mount it on the wall with the help of strong double-sided adhesive tape. Connect it to the application, which will guide you through the installation process and show you the best place to place the sensor. If a danger is detected, you will immediately receive a notification about the event on your mobile phone.
The second option for increasing the level of security in the house is the purchase of a door and window opening sensor. The device is sewn to the door jamb, but this applies not only to front doors, windows on the first floor or garage doors. The sensor also works as a guard for tool cabinets, home first-aid kits or other closed spaces to which children should not have access.
Thanks to the mobile application, family members can monitor the condition of the apartment. Any intrusion request is reported. There is already a new function of monitoring the pet's activity. The sensor can be installed on the pet door and receive a notification about the pet leaving and its return home. Security is also increased by the system being notified of half-open doors or windows when leaving the house or before going to bed.
Security alarm system or motion sensor?
Security alarm system is another step in ensuring the safety of the house before the visits of uninvited guests. The kit most often consists of sensors and annunciators. Modern sets allow for many things: connection to Smart TV, cameras or media players. On the market, you can find devices that can be controlled both with the help of a messenger and an application in a smartphone, and by voice.
Does this mean that an alarm system will provide greater security than app-compatible motion sensors? No. Modern detectors successfully cope with their tasks. In case of danger, turn on the alarm, warning the householders, as well as law enforcement services. Alarm systems are focused on a larger number of devices and cannot be associated only with the hacking function.
Which option to choose?
It all depends on the expectations and needs of the family. Well-chosen motion sensors will provide peace of mind in the house, and systems - greater convenience. Regardless of the choice, remember that even the most modern devices will not replace ordinary precautions.
