While doing some on site maintenance the clear lens cover dropped out of a customers DH-SD49225T-HN I replaced it right away using what I call security glue.........non yellowing adhesive used for installing network and comms cable. Pretty sure it will be fine. The camera has been faultless for four years. Storm approaching so it couldn't be left as is. Now I need to go around and check my other PTZ installs for the same problem. Not what I would expect from a mainstream manufacturer. Has anyone else has lens covers drop out?
