Access control is the use of devices like intercoms and keypads to solve the limitations of mechanical locks and keys. Intercoms can be used to allow entry to your home via the front gate at the enterance to your property or any door that you choose.
Intercoms can be used to allow entry to your home via the front gate at the enterance to your property or any door that you choose. You can set your intercom system up so that the channel on your television changes to the video camera at the door or gate so you can see who is requesting access. An added benefit with this system is that, for example a repair man is coming to your home but you cannot be there when they need access, when they call you you you could connect to the house remotly via your home automation syetem and open the gate and front door to your home. This stops the need to give out keys to people.
A wide range of user credentials can be used to replace mechanical keys like a pin number, radio tag, fingerprint or eye scan. When access is granted, the door is unlocked for a short time to allow entry and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.
