ankitrishabh84 0 Posted September 7, 2014 1) Can a varifocal CCTV camera be controlled through DVR? Can I change its focus of the varifocal camera through DVR. 2) Does a usual IR camera be moved to IR mode through DVR? In case where light is low and IR mode is not automatically switched on, can it be switched on through DVR control? Share this post Link to post Share on other sites
ssnapier 0 Posted September 7, 2014 I think you are looking for a box camera with a zoom function. Most varifocal cameras are best described as set it and forget it. Here is are some examples of a box camera with zoom: http://www.aventuracctv.com/480-TVL-Sony-27x-Box-Camera-OSD-RS-485-output/ http://www.amazon.com/Zoom-Box-Camera-Super-HAD/dp/B0089DULAY# <--- my current personal favorite http://www.bhphotovideo.com/c/product/855652-REG/ACTi_KCM_5211_18x_Zoom_4_MP.html Share this post Link to post Share on other sites
