if you are using a standard camera in a housing & it has<br clear="none">

I learnt that trick off someone who uses it commercially.<br clear="none">

I am interested in what experience we have collectively on using subsea cameras and displaying monitor as virtual viewports. Has any one commissioned one of these cameras? What brand and model did you use and what HMI or monitor did you use? Has it worked? What has worked well and what whould do differently on your next boat?<br clear="none">
