Window and Door Contacts
In every home, the exit and entry points are the most vulnerable to burglars. To a thief, a door or a window that isn't secure is simply an invitation to come inside. Door contacts — also known as contact sensors, entry sensors, or window sensors — are a necessary, integral part of your smart home security system.
What Are Door Contacts?
A door contact will trigger an alarm when doors, windows, gates, cabinets or other entrances are opened. Being composed of two parts (example: one part on the door frame, and the other on your door)... the sensor becomes separated when a door is opened, so the alarm goes off.
When a security system is armed, it does feature a slight delay before the alarm is fully activated. This way, homeowners have time to disarm the system with a keypad or security panel when they arrive home.
