The K2-4G is a highly configurable GSM intercom, for 2 separate properties, with remote online configuration & user management.
The unit is a robust design with brushed stainless steel fascia and powercoated stainless steel surface backbox. The IP68 antenna is pre-fitted into the top of the unit eliminating the need to install an external antenna.
The stainless steel keys on the unit are LED backlit with an IP68 silicone membrane behind for maximum protection against the ingress of water and dust.
The unit operates on 2G/3G and 4G with a 4G (vo-LTE ready) module onboard for future-proof mobile connectivity.
Door release can be activated from the user's phone keypad during a call and also at any other time by Caller-ID 'free-call', SMS, App, Web-browser or via times preset using the inbuilt 24/7/365 time-clocks (2).
The audio quality is nothing short of perfect. Configuration and user management is done via web-browser or smartphone app, primarily designed for installers.
ControlFreq apps are intended for an installer to offer a managed service to end-clients, thereby generating recurring service revenue, while providing the best possible managed service to the client – supported by ControlFreq, 7-days, by phone.
