How to allow access for visitors to access into the premise with the access control system intact?

You will want to welcome most of those who visit your premises, so it must be easy for them to let you know they are there.

The three additional products that you can add on to the access control package to allow your visitors to be able to communicate with you when you are inside, and the most common means of attracting their attention are:

• A simple door bell system which alerts your staff to the fact that there is someone waiting outside.
• An audio intercom panel which allows the visitor to have a direct conversation with a member of your staff and, if appropriate, the door can be remotely released.
• An audio-video intercom panel which allows your staff to see who wants to enter the building before permitting access.

All this will be able to add on the package on a reasonable amount.
