2024-09-12 00:00:00 You can now enhance the security of your residential or commercial building with the building security app - Gate Scanner. Are you looking for a simple, easy-to-use app that you want to install only on the security guard's mobile and keep track of visitors who visit the building premises? Disturbing residents is not right. The security guard just has to verify the mobile number of the person entering the building and click their photo for the records. The security guard won't have access to the photos clicked.
