To ensure maximum security of private home ownership and control the operation of fixtures and lamps in the entrances and on the streets, it is important to know how to configure the motion sensor and create conditions for the accurate operation of the device. Measures aimed at these tasks include the correct installation of the device and the setting of significant parameters.
Posting Rules
To optimize the adjustment of the motion sensor (DD), the correct choice of the installation location of the device in the room is important. It is necessary to place the sensor in the area where people and large animals most often pass. This rule applies not only to appliances placed inside an apartment or house, but also to structures that overlook the space outside. This approach, in addition to improving the performance of the DD, will save more electricity.
According to the placement criterion, the sensors are divided into ceiling and wall. Moreover, the principle of operation of the devices of the two groups does not differ. However, it is better to install the ceiling version in a small room at a sufficiently high height (2.5-3 m, if the dimensions allow) - then the greatest efficiency will come from its use. Such models can span up to 20 meters.
Wall options are mounted both indoors and outdoors. In the latter case, the device must be placed so that it is aimed at the places of greatest movement or crowding. In the rooms, wall models are hung at a height of 2 m. It is advisable to place the DD in the corner of the room - this ensures the best view. The maximum distance to the object upon detection of which the sensor can turn on is a variable parameter and depends on the model. Scattering rays into large spaces increases the likelihood of a false positive.
When placing the DD, it is necessary to remove lighting devices from the field of view - they can create visual distortions; and heating due to the high sensitivity of the sensor to the movement of air flows. Place the device so that no objects block the view.
How to adjust the detector
Available on the modern market, sensor models are equipped with regulators, with the help of which the user adjusts the switching parameters. Manually adjusts the lighting level, sensitivity and the period of delay off. The installation angle must be adjusted during operation. Older models of devices have only two of these controls, and when using such a device, it is recommended to purchase an additional light indicator.
Settings
Energy saving is one of the main reasons why it is important to properly configure the light sensor. If all regulators are correctly turned on, you can save up to 50% of this resource. On the latest DD models, Time controllers are usually placed - the delay period after which the control unit turns off the sensor; Sens - sensitivity - determines at which disturbance of space DD is triggered); Lux - lighting threshold.
Installation angle
In the room, most often the device is placed in the corner sector near the highest point. This position allows you to most effectively serve the area where the most intense traffic occurs.When installed in the entrance or in a room where you can get from several neighboring ones, the DD is sent to where he can cover the maximum area, so that when a living creature appears in the field of view, an alert will work.
Outside the room, you can put the device at any height, but care should be taken that objects that are not practical to perceive, for example, tree branches, are not caught in the field of infrared rays.
Sensitivity
In order for the use of the device to bring the greatest efficiency, the user needs to know how to adjust the sensor so that it works only when reading in the space of people. To do this, you need to set the sensitivity indicator to an intermediate indicator (neither large nor small) - with this setting, the sensor will not respond to the movement of small objects. You can divide the range into zones of 45 degrees with limiters - then the recognition of objects will be more accurate.
Decrease in sensitivity on the motion sensor
Sensitivity can be adjusted by two knobs with a wide range of values.
Illumination
This parameter is controlled by the Lux control. If you unscrew the indicator to the maximum value, the DD will falsely trigger in the daytime. The closure threshold is tied to a completely dark environment: deep night or closed space without windows. It is possible to reduce the indicator by connecting a photo relay or by purchasing an expensive sensor model with control of the time delay delay.
Delay time
Devices with this option have a wide range of possible values for the response speed to shutdowns (from 1 to 600 seconds), and the user can set the time according to his desire. Experts advise making it equal to one minute.
After the initial use of the device, the delay time will be slightly longer than specified in the settings, but during the second and subsequent uses, the DD will operate strictly in accordance with the user settings.
Wireless motion sensors
A distinctive feature of wireless devices is the ability to function without being tied to the mains. The nutrient element in them is a lithium-ion battery, a solar battery or a set of “fingers”. Without additional charge, the wireless sensor can function for six months to a year. The range of DDs on sale is heterogeneous in sensitivity and price.
Budget options are suitable only for indoor installation: they are able to erroneously react to a pet, are poorly protected from the action of street factors, transmit a signal only a short distance (up to 100 m). For outdoor installation, expensive models are used that work without interference in any weather. Rainfall or direct sunlight does not affect the quality of functioning of such devices. They are characterized by flexible settings and are equipped with the option of ignoring moving objects whose weight is less than 40 kg, which allows us to differentiate pets.
DDs are also issued, specially tailored to a limited area survey. Such a device is placed next to a door or window to prevent intruders. The sensor transmits a protected radio signal to the receiver. The transmission range, subject to the presence of the DD and the signaling unit in the field of view of each other, can reach 500 m.The GSM mechanism is mounted in the unit, and when the DD is triggered, a signal is sent to the control module that initiates the transmission of SMS messages to the owner’s telephone. The number is tied independently before starting the operation of the wireless DD. Such a scheme will allow you to install tracking a garage or other premises remote from a residential building.
Having taken care of the correct placement and configuration of the device before turning it on, the user will provide the best protection to the protected object and minimize the likelihood of a false alarm.
