O Hook é ideal para auxiliar em momentos de urgência, permitindo o acionamento de um alarme para emergências médicas e de segurança com apenas um toque na tela do seu smartphone ou controle remoto, que gera uma notificação automática para um grupo de pessoas da sua comunidade. Após o acionamento, o sistema notifica através de um dispositivo que conta com uma sirene eletromecânica e luz estroboscópica. Além disso, o Hook também conta com acesso ao chat durante a emergência, identificação do usuário com seu endereço e contato, disponibilização de ficha médica e ainda se integra à câmera de segurança.
