I have been using the HFW4300S model for a couple of years. The company I work for is always expanding so I install around 10-12 cameras every couple of months. The 4300S has so much better images vs. the HFW1320S, HFW4421S, etc that I'm able to get on amazon now. I've tried them and sent them back due to the image being more grainy than the 4300S models I have all over my current installations. Has anyone else noticed that these new sensors aren't as good? Any suggestions on a good model in the 3-4mp range?

Yep, thanks, that FS108P was already there from a previous IP cam installation by a local alarm company, and now that I'm responsible for the place I put in my own stuff before realizing the switch was the problem. I had never run into it before because I use a Procurve 2530-24G at home with my setup but that switch would have been way overkill and too expensive for this install.

It definitely was the switch. Watched footage from a busy night last night and it's all smooth video now.

I started thinking about it being some sort of network issue so I went in yesterday evening and connected one of the cameras and the DS115 to a HP Procurve switch and uplinked that to the rest of the existing network to see if anything improved with that one camera compared to the rest of them and I think it did. While I can't justify leaving a $1200 switch in this small bar, I did order a Netgear GS108PE as a gigabit replacement to the FS108P switch that is in there now. I also took another DS115 and a couple of the same model cameras and set them up in a test environment using a better switch than the FS108P and didn't have any of these issues no matter how much or how fast I moved. The bad thing is I really have to wait until Thursday night when the bar is open again to see for sure if it's fixed.

Last night I changed the fps to 10fps, 10 iframe, and 2048cbr on one camera and turned off the noise reduction on one of the others and left the third alone. Still the same results. I just went by my office and picked up a new in the box DS115 and two unopened HFW4300S cameras to set up in a test environment and then I'll start swapping out settings and parts until I figure it out I guess.

This is a Dahua HFW4300S set at 1920x1080 20fps CBR 4096 recording to a Synology DS115 running Surveillance Station 7. I'm not sure you see this when just viewing the camera in a browser, so I'm wondering if it's a Synology issue, a bitrate issue, etc. I have two more of these exact cameras in this bar that are doing the same but yet I have three of them at home (outside, not inside) with a Synology RS814+ that have never shown this behavior. The issue starts around 26 seconds into the video and does it again when I get near that back post also. The video is the mp4 file off the Synology. 7b00jwAEQL8
