Key-less entry? Sounds great! This feature allows you to unlock doors without keys and to keep track of people who are coming and going. You can even set up employee time schedules that control when specific employees are allowed building access during the work week, weekend and/or after hours. Access control is also a valuable tool to integrate into a home-automation system. For example, at the time the access control receives a valid entry it can turn off your security system, open/close the blinds, turn your lights on/off, set the thermostat, turn on your TV, turn on music and even turn on the coffee pot. It can then reverse these actions when you leave!
