HTTPS is now a requirement ========================== This package now depends on Apache's mod_ssl package. This will automatically be installed along with ZoneMinder. Upon installation, the mod_ssl package will create a default, self-signed certificate. This is the certificate that ZoneMinder will use out of the box. Since the certificate is self-signed, you will get a warning from your browser the first time you access the web portal. This is normal. This is not intended to be an all encompasing solution for everyone. ZoneMinder will work just fine over HTTPS the way it is currently configured. However, here are a couple of considerations you may want to take. 1. Create your own certificate. The CentOS wiki has a guide that describes how to do this: https://wiki.centos.org/HowTos/Https . Additionally, Googling "centos certificate" reveals many articles on the subject. Note that some third party applications, such as zmNinja, will require you to create a certificate different than the default certificate on your machine. 2. You can turn off HTTPS entirely by simply commenting out the SSLRequireSSL directives found in /etc/httpd/conf.d/zoneminder.conf. You should also comment out the HTTP -> HTTPS Rewrite rule.
