lucha 0 Posted September 5, 2011 Does anyone know about IVS camera from Avtech? There are some model with new feature, such as AVK 522 has smart zoom function. So, I guess these cameras use varyfocal lens. Is it right? Where do I have to install the camera? Can I put in crowded places or only in certain area that doen't have a lot of people? How about the lifetime of this camera since it has motorized lens? Because if the cameras doesn't use varyfocal lens, the zoom will be digital zoom. And the result will be not clear enough. How about AVM602V, does it have smart zoom? Thank you very much Share this post Link to post Share on other sites
