Intercom system automatically takes your home security to a whole new level. The system is so designed that it makes a connection between the external front-door unit and the interior of the house using speakers & microphones. Thus, whenever someone presses the door bells, you are instantly alerted and you can directly speak to the visitor (from the safety of your interiors); ask him to introduce himself or the reason for his presence. Being a two-way communication device, Intercom also enables the visitor to answer back to you and thus you can make up your mind on whether the visitor is familiar& expected or stranger & suspicious. Thus, any untoward incident of forced entry by a crook can be avoided.
