JasonOfOz Posted October 10, 2013 Share Posted October 10, 2013 Hi Everyone, Our Client would like to get a head/shoulders shot of people as they enter through the main entrance door of the building. Current camera position is 7m away from the door. My calculations suggest that I would need a 45-60mm lens. Mostly that would mean a box camera with lens attached but he thinks it's ugly looking so does anyone know of a dome camera with a long lens on it as I've never come across them before. Thanks! ps. needs to be wide dynamic too (just to make things even more challenging) Link to comment https://www.thesecurityinstaller.co.uk/community/topic/35432-dome-camera-ideas/ Share on other sites More sharing options...

JasonOfOz Posted October 10, 2013 Author Share Posted October 10, 2013 not really. DDA width of doors should be 900mm don't want it too much wider or won't get head/shoulders. ps. i hope the arm is healing nicely Link to comment https://www.thesecurityinstaller.co.uk/community/topic/35432-dome-camera-ideas/#findComment-348326 Share on other sites More sharing options...

RichL Posted October 10, 2013 Share Posted October 10, 2013 something covert with your choice of lens might be the way to go, have a look at systemq. Originally said by Charles Babbage On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
