    Our solution does not require the installation of individual fixed audio/video door stations in the tenants' unit. It works on current smartphones and tablets as long as there is an Internet connection. This automatically brings down the cost of installation and equipment.
    Our ZerCon feature which is short for zero configuration means there is no need to perform complex technical configurations on the tenant's mobile devices. We will assist the client on how to use the service and we will handle all customer support issues to allow the building admins to focus on their core business. Help is available online 24 x 7.
    Audio door intercoms can deny the tenant from seeing who is ringing the door bell. A flaw that is often exploited by thieves and trespassers. With Kontaxio's door cam solution, we hope to prevent theft and trespassing from happening.

    All door intercom stations are normally installed in a fix location of the apartment unit. To answer the doorbell, the tenant has to stop what they're doing and physically go to the door intercom station.

    With Kontaxio's door cam solution, tenants can check and unlock the main building door from anywhere* in the apartment from either a smartphone, tablet or computer.

    Tenants can also use their smartphones as an alternative to the physical key or they can use it to unlock the main door / gate for their guests regardless of where they are*.

    *Internet connection required

    Trivia: People nowadays will likely forget their door keys when they leave the house, but will almost never forget their smartphones.
