A quality video intercom is not only composed by a device similar to an intercom and a camera. There are some features that are essential for its good functioning.
Night vision: If the video entry camera does not have good quality night vision, it will be useless at night. It is necessary that clear images are produced regardless of the time of day.
Connection with locks: The best video intercom models can be connected to more than one lock. Thus, the device can control access to various environments of the residence or company.
Call transfer: If you can not be on site all the time and eventually need to approve access from afar, you can register a mobile phone number and do the control through this device. This makes your life much easier!
