Setup Digital IO for Relay output

[Willy]

Hello, I am new to Blue Iris. What I like to do is setup BI to trigger a relay when there is motion. What type of IO relay card is compatible with BI.

Thanks

Several options if you explore the manual. Maybe the easiest is an Arduino on a serial port. Then output the Arduino to a relay board. Per the manual, SeaLevel apparently makes some DIO (digital input/output) boards that it can talk to.
