Hi everyone, I have a question and please help me as you can. I want to connect my DVR with a universal GSM dialer, in order to get notifications if something is wrong. I know with power cut it can be done but how can i connect the GSM to get notifications for Video loss. The DVR Cant be networked because its located in a field with no internet access. I know the DVR makes a beep noise when there is a power loss , so my question is , can i use that circuits voltage closing to trigger an input of the GSM? Can anyone help please?
