Berg en Dal Estate is a Secure Estate which provides various physical, technological and human barriers as a first line protection system for the residents of the Estate. The Estate also restricts access to the estate by Visitors, Contractors and Domestic workers. However no systems are fool proof and must be continually maintained and upgraded as technology advances to counter the increased sophistication of perpetrators attempting to enter the Estate.

The Board of the Home Owners Association, while using its best endeavours to ensure that the estate defences are as good as possible, recommends that all residents also have their own alarm system installed, properly maintained and switched on at the appropriate times.
