I am absolutely new here in the forum and on the topic ZoneMinder. At the beginning I greet you and sorry for my bad English

First I tell something about my ZoneMinder System. I use a Raspberry Pi Model 4 with a Ubuntu 18.04.4 LTS Server operating system. As a datastore I use my Synology with a NFS share. I linked the complete "/var/cache/zoneminder" directory to my Synology. I use the ZoneMinder version 1.34.7 with a MySQL database and a Apache webserver with SSL only. I use two Vivotek IP cameras FD9367-HV and FD8369A.
I use this thread for my questions. Thank you!
