I'm in the process of building an alert system that can be manually triggered via the dahua app (gdmss) through the NVR. The scenario would be: a customer is alerted that a person or vehicle is present, the customer pulls up the camera via app on phone, to verify, and then could trigger the alarm via app to deter the trespasser. Testing on the 5216, most of it is working as I attended, except that I cannot figure out how to have the alarm out (NVR) cycle for a specified amount of time. I see in the app when I select the alarm icon, I have the option to "open" or "close" to turn the alarm device on or off. What I would like to do is be able to have it turn on for say 30 seconds, then automatically turn off. Is there a way to do this? Or am I stuck having to always manually turn it off once activated? Any other advice or suggestions appreciated.
