Считать сухие контакты через ONVIF Dahua/SNR

Специально не стал создавать тему в разделе Dahua, ибо, не исключаю, что такое поведение на всех камерах.

 

Как считать состояние сухих портов через ONVIF?

GetDigitalInputs возвращает только наличие самих портов, но не их состояние:

В стандарте есть способ получения состояния через Events, но мне в работе он не очень удобен (не могу постоянно отслеживать события). Существуют ли адекватные способы через ONVIF?

Blacklotus, это через механизм Events. Я так понимаю, в ONVIF другого способа и не существует.
