Log Errors on New Install

[jimkoh]

I just installed ZM 1.34.25 on Debian 10.09 and am getting the following errors:
Failed to write frame image
Can't open /mnt/surveillance/3/2021-04-25/34/04841-capture.jpg for writing: No such file or directory zm_image.cpp 1042

There are a now thousands of these. Any idea what's going on?
Thanks
Jim

Most likely it is a security issue.

This is my #3 directory:
