Cronjob to delete folders & files older than 3 days?

[fahl]

I have 4 cameras that automatically store .jpg & .avi in seperate folders for each camera.
I wish to use cron to delete folders & files after 3 days.
Can someone please point me in right direction.
Setup is folders


ftpcam/cam1/cam2/cam3/cam4

New daily folders are generated in these folders.

I wish to delete all folders & files over 3 days in these folders.
tried

find /home/*****/public_html/ftpcam/{cam1,cam2,cam3,cam4}* -mtime +3 -exec rm {} \;

But doesnt seem to work.
Any help much appreciated

Getting this error

rm: cannot remove `/home/bumsrush/public_html/
ftpcam/cam1/20180327': Is a directory
rm: cannot remove `/home/*****/public_html/ftpcam/cam1/20180325': Is a directory

Hello,

You'd need to update your "find" command to account for directories. Here's a third-party URL with an example:

delete file/folder older than x days

Thank you.
