@austwhite can type faster than me so I won't re answer but in ref to your edit- How many snapshots are taken is going to be determined by how often you tell BI to do so along with all the other ways you can limit that. AI-
Tools is not triggering BI it is simply sending the images to DS (that is my understanding) If your queue is getting filled up then you may need to update your BI box, I have no idea of your set up so I am making an assumption here, Mine is set up all on 1 computer (no DOCKER) and my computer is a old ass Dell optiplex, I have never had queueing issues myself (9 cameras). As far as how to write the trigger do a search here or check out one of the several threads on GitHub or some of the alternate set ups on YouTube, there are no shortages of examples. I struggle with that topic myself simply because I have no flippin idea how to write
them.
currently I am using these:
[BlueIrisURL]/admin?trigger&camera=[camera]&user=[Username]&pw=[Password]
[BlueIrisURL]/admin?trigger&camera=[camera]&user=[Username]&pw=[Password]&flagalert=1&memo={Detection}
and in the Cancel block this one:
[BlueIrisURL]/admin?camera=[camera]&user=[Username]&pw=[Password]&flagalert=0
This is exactly how they are entered the user/PW info is on a different location in AI-Tools and get pulled from there *that is how it is with version I use you may have a newer or older version.
**Again I am no expert so if jacked anything up someone PLEASE correct me so there is not bad info out there.
