Sean Mao 0 Posted August 15, 2015 There are three ways to realize motorized lens camera with auto focus and auto zoom function (1).Synchronized Motorized lens: the focal length is adjusted with one motor on vari-focal lens to make sure each focal length have a clear view. when camera got auto focus commands from DVR, camera will change its focal length to get better video performances. this way is simple and stable to realize auto focus function. (2).Non-synchronized Motorized lens: the focal length is adjusted with two motors on vari-focal lens (one motor for zoom,the other one for focus),when camera got auto focus commands from DVR,camera will drive the zoom motor,then drive the focus motor to get the right focal length. (3).Auto focus by Algorithm:camera DSP will adjust the focus length to get a better video performances automatically by algorithm.video will be a little blur in night time in this way,because the light condition is variable and unstable in night. I post this topic for more people in this forum who have other opinions on motorized lens camera.Thank you for reading it and welcome to talk about this topic in this forum ------------------------------------- Sean Skype:mxtforever email:mxtinlv2015@gmail.com www.smart-views.com ------------------------------------- Share this post Link to post Share on other sites
