Query: What a piece of junk

I have many cameras, network and otherwise, PTZ and fixed, and this is by far the worst one. It has difficulty focusing, it's noisy, doesn't hold presets well, and the image appears to start "melting" every few seconds, then snaps back to clear. The wireless connection is pretty reliable, but that's about all I can count on. The API support for this thing is nil, along with the options they give you. Tech support is usually no help at all. I just purchased an Axis 213 PTZ, and it completely blows this thing out of the water. No more DLink for me.
