Wireless Door Bells operate via GSM technology or local Wifi network. They are especially designed for companies where are not staff at all times.
When the mail or courier arrives, the driver push´es the “door bell”. They are immediately connects to the company staff by telephone. It will be easy to agree procedures immediately. The door phone has an integrated door opening system, so the electric lock has the ability to allow the driver to enter if necessary.
A door phone with a keypad can be used to open the door with a code number. A multi-channel door phone connects to multiple apartments in the property through the same device.

If devices are operating over a Wi-Fi network then they will make a local alarm and connect to the phone after, for example, in 15 seconds. The visitor can leave a message or hear the voice message themselves. He can be let in by an electric lock or be captured on video.
