SentryAlertSystems Posted June 14, 2015 Share Posted June 14, 2015 Anyone ever fitted a camera where you have to deliberately set the camera just out of focus to compensate for the curvature of the hemisphere? #american dynamics Quote Link to comment Share on other sites More sharing options...

JB_ Posted June 14, 2015 Share Posted June 14, 2015 I read it as its a PTZ and the hemisphere is the perspex on the bottom, wouldn't that just be piss poor manufacturing?  Or was it the curvature of the northern hemisphere of the earth? Sounds like one hell of a wide angle lens if so.

SentryAlertSystems Posted June 14, 2015 Author Share Posted June 14, 2015 The perspex bubble, yea. Was being modest by saying 'just' out of focus. Was like putting your nans reading glasses on. All in all a good camera though Quote Link to comment Share on other sites More sharing options...
macca6934 Posted June 25, 2015 Share Posted June 25, 2015 I've had similar problems with older Axis and Indigovision cameras. They seem to have sorted this now with the more up to date models. Quote Link to comment Share on other sites More sharing options...
