The kit allows use of the video entry phone system via tablets and smartphones on the Wi-Fi network, or remotely on 3G (or higher) networks.
The gateway in the pack allows connection of other devices (Comelit VIP door entry monitors or PCs). In all cases, the gateway should be connected to an ASDL router or another device guaranteeing local Wi-Fi and mobile 3G connectivity.
Depending on bandwidth limitations, the gateway can serve up to 16 appliances (including door entry monitors, smartphones, tablets and PCs) with 4 simultaneous door entry monitor streams.
It also allows "intercom" communication between all of the 16 devices served.
For mobile devices, whenever both modes are available and enabled, the APP automatically switches connection, from Wi-Fi to 3G and viceversa.
The kit consists of: 1 colour audio/video unit art. 4682KC, 1 module with 1 button art. 33411M, 1 flush-mounted box art. 3110/1, 1 frame complete with finishing frame art. 3311/1S, 1 power supply unit art. 1595, 1 power supply unit art. 1441 and 1 master gateway 1456. The kit is pre-programmed and ready to use, except for 1456 gateway configuration which must be carried out via internal web server.
