With the increasing demand in security for estates, video surveillance system is installed to monitor the public areas for security incidents. The use of video surveillance system saves the security resources and allows the security guards to remote monitor different locations in the estate in one single screen. The system keeps the video for days and even months. The video can be played back later for criminal activity investigation.

Besides, smartcard becomes an essential part of daily life. Every resident is assigned with a smartcard and they can travel around their estate with it. Main gate, tower entrance door, car park and even lift can be equipped with smartcard readers to prohibit unauthorized access. With one single card, residents can get into the clubhouse, and pay with smartcard for facility booking. Estate is a private area, to keep track of visitor activities, a visitor management system can be used to record the date, time and reason of the outsiders to enter the estate.
