Magnet Sensors for Door and window Security
Home and Workspace security is paramount and most newly constructed spaces integrate security products during construction. Security consists of monitoring the state of doors and windows, locks, motion and having them controlled by a central controller which is generally integrated to an smart phone or a custom website.
Reed Switches are used in the production of sensors for monitoring the state of doors and windows as well as locks. Magnets are mounted on the interior frames of doors and windows, and the reed sensors, on the fixed frames. As long as the doors or windows remain closed, the contact is not broken.
Normally Open, or Normally Closed reed sensors can be used depending on the circuit logics but in most cases, normally-open devices are preferred. Special reed sensors which contain highly accurate magnets can even sense metal doors using the principal of field shunting. In a workspace or a home installed with door and window security, information such as which door needs to be closed at the time of exiting the place, or how many times the front door was opened can be collected and saved for analysis or push notifications to mobile devices.
