ionu 0 Posted December 29, 2008 Is it possible to add an IP PTZ to an existing system? The existing system is a 4 camera max plex dvr connected with coax cable. It is accesible via the internet. Any comments would help. Share this post Link to post Share on other sites
Soundy 1 Posted December 29, 2008 The DVR itself would need to support IP cameras, and it would need to support the specific IP camera you're using. Share this post Link to post Share on other sites
