Automatic door locking mechanisms, door phone systems, fingerprint door lock system, retina scan before the door opens, gate automation etc are all systems that are available in the market for home security.
Sensors, magnetic locks, electronic strikes etc are used to for door security systems. Card readers including magnetic stripe and barcode cards are also very popular. These cards need to be held near the door sensor. Door systems like the voice, finger print and iris scanners are the most secure as well as expensive systems. Electric strikes are a good option for the corporate world as they are cheaper and better for doors. Magnetic locks can be used for situations where users have to check in and check out of secure areas. Doors can also utilize magnetic contact sensors to detect the visitor when the door or window is opened. The sensor is placed on the frame of the door or window, and the magnet is installed on the door itself.
