I suppose 5.7.4.2 and 5.7.6.4 are 'old' by today's standards, huh?
Anyway, my tried and true rock solid 5.7.4.2 has the earlier 'Get ONVIF Trigger Events' option in the IP cam configuration pane but lacks the 'ONVIF/Camera Events' configuration option available in 5.7.6.4. (a demo). The latter works as one would expect. The former on my main server is giving me a run for the money and I can't quite figure it out or find equivalent options to the 'ONVIF/Camera Events' section provided in 5.7.6.4.
Any assistance in pointing me toward the snake that probably should have bitten me already will be appreciated!
