SentryAlertSystems Posted June 14, 2015 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

JB_ Posted June 14, 2015 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. Quote

SentryAlertSystems Posted June 14, 2015 Author 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
macca6934 Posted June 25, 2015 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
