The detection range of alarm sensors varies depending on the sensor type, model, and installation angle. Not all sensors cover the same distance. Motion sensors, glass break detectors, or outdoor sensors have different detection areas.
How many meters away can motion sensors detect motion?
Standard indoor PIR motion sensors typically include:
-
Detection range of 8-12 meters
-
90° – 120° viewing angle
It has.
The number of sensors should be planned according to the size of the room.
How many meters away can outdoor sensors detect?
Outdoor dual-tech sensors:
-
It can have a detection range of 10-15 meters.
Infrared barrier systems include:
-
20 meters
-
40 meters
-
60 meters and above
It can provide protection over long distances.
How many meters is the effective range of glass break detectors?
Acoustic glass break sensors typically:
-
It covers an area with a diameter of 6–9 meters.
A single sensor can protect multiple windows.
Is there a magnetic contact distance?
Magnetic contacts do not measure distance.
It is triggered when a door or window is opened.
However, the distance between the magnet and the sensor is usually:
-
It should be between 1 and 2 cm.
How many meters does gas and smoke sensor coverage cover?
These sensors are not distance-based:
-
It operates based on the concentration of gas or smoke in the environment.
A single sensor can cover a specific area in square meters;
However, multiple detectors are recommended for large areas.
What factors affect detection distance?
Detection performance depends on the following factors:
-
Sensor quality
-
Mounting height
-
Viewing angle
-
Ambient temperature
-
Whether or not there is an obstacle
Incorrect installation can reduce the spacing.
Will a blind spot form?
Yes.
In case of incorrect positioning:
-
Behind the furniture
-
corner of the wall
-
behind the column
Areas such as these may not be detected.
That's why professional investigation is important.
How many sensors are needed for large areas?
In large areas:
-
One sensor may not be enough.
-
Planning is done by dividing the area into zones.
Sensor distribution should be based on square meter area.
Sensor Planning in Workplaces
In warehouses and stores:
-
Shelf height
-
Open space width
-
Entry points
The number of sensors is determined by taking this into consideration.
How to Create the Most Accurate Distance Plan?
For proper planning:
-
The square footage of the space should be measured.
-
The sensor's technical data should be examined.
-
A test setup should be performed.
Professional scouting plays a critical role at this stage.
