Anyone tried zoneminder for camera control

From time to time it'd be nice to have a remote control camera
connected to my Pi. Most likely use would be watching for
unwelcome critters in the garage or garden.

Knowing absolutely nothing I downloaded zoneminder. It looks
like a much more complex system than I need, but it's available.
At this stage I'd just like to find out  if it runs on a Pi4
running up-to-date 64 bit RasPiOS. It's installed but the man
page is little help and running zmu reports a permissions error.

Any tips or links would be much appreciated.

Thanks for reading,
