I have one of the new hikvision WiFi doorbells in the UK, and as we don’t have 16v-24vac chimes in this country, I am having a challenge in finding a solution for a chime. Has anyone found a solution to trigger some sort of digital chime using the output of a hikvision DVR? So when the dvr receives a signal from the WiFi doorbell, I link it to an alarm output, thus sounding the chime as an alternative to connecting it to the doorbell itself.
