The installation cost will depend on your door type and configuration. The Proxy Mobile Reader is installed in a similar manner to other door readers so it is something that a typical security installer should not have a problem installing. If the installer of your choosing has any questions, we would be happy to have a conversation with them and provide clarification as needed. The installer can also provide you with a quote after they've had a chance to do the assessment. Proxy can only provide a cost for the Proxy Mobile Readers and subscription monthly charges.
