Ajax DoorBell has been designed to modernise the traditional video door entry experience by integrating compact design and advanced security technology into the Ajax ecosystem through the JetSparrow transmission protocol, developed by Ajax for the efficient transmission, storage and management of video data. It is designed to provide ultra-fast and stable video streaming in real time, without delay or interruption. It uses peer-to-peer (P2P) technology and TLS encryption, ensuring secure data transmission. Thanks to its high efficiency, it enables smooth navigation in both live viewing and archiving of recordings, optimising the monitoring and security management experience.
With long-rangeWi-Fi connection and secure backup, the Ajax DoorBell operates with 2.4 GHz Wi-Fi , but in case of network failure, it guarantees continuity thanks to the proprietary Jeweller and Wings protocols.
