Door access systems update you on who enters and exits your property. They create an audit trail of who and when someone accesses a particular area. The systems also allow you to set access restrictions to private spaces, create a roll call in the event of fire and clock staff members in and out. Access control is a preventative tool to use against unwanted visitors and crime.
You can also choose to install voice recognition systems, allowing you to talk to a visitor before enabling entry. Used both on domestic gates and commercial properties, door access systems are adequate security measures 24 hours a day.
