Can we take just snapshots without loading the RTSP stream ?

[Softwaremaker]

Hello Folks - thanks for this project. I am evaluating this but I have some constraints

I will be running this in a Synology NAS where RAM is extremely limited and tight. We are talking about 500MB only.

I have 4 cameras that I just need to pull snapshots and not streams. Is this possible with 500MB of RAM and crappy CPU ?

Thank you
