In many cases if you use find/inspect for your camera this option will be checked. I have it checked on three different Hikvision camera models as I'm successfully able to use Hikvision's intrusion detection features with
Blue Iris instead of using the camera's and BI's motion detection features which cuts down on false alarms (the feature also enables the use of line crossing detection in BI, but don't use it). Anyway, I also get the subscription warnings in the BI status window for these cameras--are these warnings expected indications when the pullpointsubscription box is checked, or is it simply an incompatibility with my particular cameras? BI Help states:
The
Get events with PullPointSubscription setting is set automatically if you use the Find/Inspect tool and it discovers that your camera supports Events. The software will monitor the events stream from the camera in order to facilitate camera-based motion detection and triggering, which also must be enabled on the Motion/Trigger tab. It has been found that some cameras do not properly support this, resulting in a high network activity as the software attempts to pull the events, in which case you may wish to override this feature by disabling it.
