I'm not really sure why/if you meant to put this in the #Module Development subcategory - it doesn't sound like that's the way you're leaning.

> I tried calling the camera’s ONVIF endpoints directly from Ignition using `system.net.httpGet` / `httpPost`, but I always get **401 Unauthorized**. ONVIF requires WS-Security (UsernameToken, PasswordDigest), which is hard to implement in Ignition’s Jython scripting.

Never use `system.net.httpGet/httpPost`, always use `system.net.httpClient`.  
There are some examples floating around this forum of doing digest auth via scripting, e.g:

> [@\[IGN-4258\]Digest auth with httpClient](https://forum.inductiveautomation.com/t/ign-4258-digest-auth-with-httpclient/66137/10):

Tangential, but MongoDB seems a very strange choice for binary file storage. NoSQL gives you no benefits if you're storing well formatted binary image snapshots.
