In olden days, security meant shutting doors and locking them to prevent intruders. Today, entry systems for apartment buildings, offices and homes in London have gone beyond simple locking and unlocking of doors. Keeping threats out and providing the feeling of security has become a vital aspect of living in a modern society.
These days' most residential, business and office premises in London use entry systems. Entry systems provide security by letting a person talk to the visitor through an intercom/telephone or see the visitor through CCTV. Once the person is satisfied and wants the visitor to enter the premises, he/she just needs to press a button to open the door.
There are many different types of entry systems in London. Though the basic function is of controlling and ensuring that only right people have access to a designated location, these different products can be used for different purposes depending on the specific need of the end user.

3) Card Readers: Users and swipe the card through the card reader to activate the door release.
