Effective motion detectors can significantly increase the security of your building.
Motion detectors are one of the most crucial components of a truly integrated security system.
Quality motion detectors can detect unusual movements, the opening or closing of windows or doors, as well as detecting and reporting intruders.
Additionally, strategically placed sensors can detect when someone approaches a property entrance or when unauthorized persons attempt to enter a restricted area of your business, such as a server room, security office, direction, a safe or any other critical space.
The three main categories are: Dual Technology Motion Detectors, Microwave Detectors, and Passive Infrared Detectors.
-
To identify intruders, passive infrared sensors are made to detect body heat. After the sensors “warm up,” they surround an area with a protective grid that can help the system detect threats. The detector’s sensor is triggered when a moving person or other hot object disturbs the grid and changes the energy level of the system.
-
Dual technology motion detectors limit the possibility of false alarms by combining passive infrared and microwave sensors. Dual-technology motion systems must first trigger both sensors for the alert to trigger.
-
Microwave detectors are created to deliver pulses of microwaves and determine how quickly moving objects reflect those pulses. Compared to their infrared counterparts, microwave sensors can easily secure a wider area, but they can be susceptible to electrical interference.
-
Type of reflective area. To secure a space, the sensors generate infrared light through LEDs. To assess whether people or objects have entered a prohibited area, their sensors calculate the distance between people or objects and the detector.
-
To detect vibrations, vibration sensors use a small device on a lever that activates a switch when a vibration occurs nearby. These sensors can be unreliable, although they are clearly low-tech (and simple versions can even be built at home). They are also not susceptible to being influenced by electrical interference.
Motion detectors are useful for a variety of tasks, security and logistics
Motion detectors can be used for a variety of other security purposes, in addition to being used to monitor the perimeter of buildings and other properties.
-
Coupling with video surveillance: The motion detectors are sometimes used with cameras to initiate the recording process. Solid-state hard drives have made this less necessary, but motion sensors continue to notify cameras to flag crucial footage for later review or to immediately signal security personnel to focus on a flux.
-
Motion detectors are well suited to be part of access control systems, such as turnstiles. Plus, when someone enters a space, motion sensors can instantly turn on lights or secure doors.
-
Automatic doors: During working or opening hours, motion detectors naturally open and close automatic doors in businesses, schools or businesses. When someone approaches a door or enters a certain area, they can also trigger an alarm or activate a doorbell.
-
Also, intrusion detectors: Of course, alarms are often built into motion detectors, and they sound when motion is detected.
Motion detectors enhance the ability to detect hazards that visual means alone cannot detect. They help security guards focus their attention on particular CCTV areas. Using them as part of an overall security strategy can provide an additional and crucial layer of security. Especially if the connection of the device is secured by encryption like, for example, the motion detectors for security alarm from Ajax.
