Good to know who's knocking For your own safety, it's always good to know who's at the door before you open it. The Sygonix Wi-Fi door intercom with peephole notifies you of visitors via push notification when it detects movement and rings the doorbell. Contact can then be made either via the 10.9 cm (4.3 inch) TFT LCD screen or, if you are out and about, via your mobile device. Burglary protection Burglars like to ring the front doorbell to find out whether a property is empty. The real-time video function of the Wi-Fi door intercom makes it possible to see who is asking for entry at any time and from any location. It can also be used to pretend to be present. The option of video recording also acts as a deterrent and may help with later clarification. MicroSD cards of up to 64 GB can be used for this purpose. Flexible use The Sygonix Wi-Fi door intercom can be used universally as it is battery-operated, so does not require a power connection, and supports Amazon Alexa and Google Home. The door thickness can be between 35 and 105 millimetres and the compatible hole diameter ranges from 15.5 to 60 millimetres. In addition to the peephole camera and indoor monitor, the scope of delivery includes a USB cable, a reset pen, the manual as well as a bracket and screws for installation. Special feature: spy camera.
