Reply To: How to choose the best intercom system?
The presence of a memory unit in aiphone intercom is quite expensive, which means that models with it are rare. The device with a memory unit is capable of automatically photographing guests or bystanders who are near the entrance to the facility or house. The data obtained is stored in the memory of the device and can be transferred to a computer. The functionality of such intercoms is not limited to photographing people. If you want, you can connect motion sensors to the door station, so that when someone appears near the entrance, the shooting starts automatically.
