I don't know about the 601 model. I think it just might be my camera, as some of the other videos that others have posted look much better than my camera. I guess I can't complain too much as I only paid $167.90 total for the camera. I do like the camera, as the daytime image is slightly better than my 2 Huisun Mini Bullet PTZ cameras (in my opinion). I plan on keeping the Sunba in it's current position. I plan on replacing my Hikvision DS-2CD2032-I 12mm camera that monitors the dirt road behind our house with my spare Huisun Mini Bullet PTZ. I will use the Huisun at night for manually tracking anything of interest. Here is a sample screen capture from the Sunba last night. I spotted a coyote on the hill behind our house last night just before 1AM running back and forth underneath our pine tree. I guess the coyote was hunting something on the dirt road below the pine tree. When I tried to zoom in on the coyote, the Sunba IR just about blew out the coyote (the camera wasn't recording at the time so I don't have a sample). Items at a further distance look quite good with the Sunba, like those cars you see at the top of the image. I can zoom in on those cars and see good detail at night.
