I just found this recent video https://www.youtube.com/watch?v=5MoynorQ3y0
Since he stated he uses Blue Iris (Unless a specific camera doesn't), they will obviously work with BI too

Glad to see he thinks the same as me; a PTZ could be a useful addition to a system, but it can't really replace a few well placed fixed cameras. Just look in the movies - wait for the camera to pan the other way - and run
