Dear Derek and IPVM team,

Thanks for testing Unview products.

I want to explain one of the “disadvantages” in your test – No Simple Autofocus.

Usually, zoom adjustment is a necessary step during installation for varifocal cameras. Uniview’s cameras support auto focusing after the cameras are manually zoomed to provide better image quality.

This function avoids unwanted autofocus in case of a scene change, compare to these cameras support autofocus by detecting scene change. We believe it’s more easy-to-use and it meets the needs of the deployment.

Thank you.

Thanks for that explanation. I agree with your main points that auto focusing after zooming is necessary and focusing on scene change is a good feature, at least in theory.

The issue we have seen is that auto focus on scene change sometimes fails, and when that happens there is no simple way to trigger auto focus again to get the camera in focus. We actually have seen auto focus sometimes fail when zooming from very wide to telephoto, as well. So having a way to trigger autofocus manually simplifies things in these situations.
