Smartphone-Based Access System

Highlights

After upgrading the client’s intercoms to a comprehensive security management system, PSA was entrusted with further enhancing their product line. The next step was to strengthen access control through a mobile app, making it a key link in building a robust security ecosystem.

Challenge

Client Challenge

Empower the security management system by providing smartphone-based access control.

Project Objective

Create a mobile app that provides access intercom functionality, to be integrated within the client’s security management systems.

Solution

To ensure the app functioned effectively as an intercom, the PSA team conducted a deep investigation into the client’s devices and identified the most suitable connectivity options. We reviewed the original system’s functionality and capabilities to set clear business objectives and use cases and delivered an initial UI demonstration to align expectations.

Running on both iOS and Android, across smartphones and tablets, the intercom app enables reliable communication and access to premises. It acts as the central coordinator and controller for all intercoms deployed on-site. We ensured the app delivered the following key features:

Device discovery in the network using the proprietary protocol
Audio and video calls between doors and the app, as well as app-to-app communication
Secure door release functionality with SSL encryption
Broadcasting messages to multiple devices simultaneously
Push notifications in real-time

Our team replicated the core business logic of the master intercom, ensuring full compatibility with network devices. Significant efforts were devoted to protocol-level scope, defining and implementing discovery and configuration protocols to seamlessly integrate with third-party SIP stacks, which the client intended to use. Licensing and configuration options were thoroughly researched and integrated to meet all client requirements.

To optimize system performance, we conducted extensive engineering tests to assess memory consumption, ensure smooth business logic implementation, and validate the app's operation in various environments.

As a result, our client received a user-friendly mobile app that controls entry to the premises without the need for an intercom device inside. This innovation allowed the client to offer their customers more advanced and flexible security management solutions, enhancing the overall security ecosystem.
