I just bought five more of the IPC-T5442TM-AS. Below is a sample on how well this camera is with low light. It's almost 10pm at night, my backyard has no lights and this camera is still in color mode.

Wooo, that is bit good even has snow at 10pm.
(Edited) I am definitely impressed with the better nighttime view compared to a IPC-HDW5631RP-ZE it was replacing. How do I clean up the blurred image?

Something doesnt seem right about those images... I've installed many dozens of the 5442's and have'nt seen anything even close to that bad. Looks like very low bitrate substream images
What bitrate are you running? and what Expsosure and DNR?
Odd how certain plants are blurry and others arent?

Agreed - that is a low bitrate and maybe some backlighting going on.
I have that with one location where you have a lot of bright contrasting imaging and processing the camera has to do. Most of mine I can run fairly low, but one spot, regardless of camera, has to run a higher bitrate.
Try like 20,000 and then back down until the image blur starts again.

I had it set to VBR and the bit rate showed 2560. All my other cameras set to VBR with bit rates 4096 or 5888. Raising it up in intervals up to 20000 cleaned most of it up. I will lower it back down to a good spot

I found 8192 to be optimal for my setup, but YMMV.
Will it fluctuate much under VBR? Should I use CBR to keep it at a set rate?
For a problematic camera spot like that, yes use CBR. What is happening with VBR is it is a static image with a lot of processing going on but the bitrate drops because of no motion.

Agree. I prefer CBR on all of my cameras and 8192 is a good rate for a 4MP camera. 2000 is way to low

Thanks for the info. All of my 2mp and 6mp cameras have stayed between 4096 and 5888 with perfectly clear images. I kind of surprised that I'm having to adjust bit rate on this one quite a bit higher to clean the image up. I will give CBR and 8192 a try.

frame rate and I-frame interval the same (which on the 2mp model I did just fine) the camera has a problem doing the compression correctly.Instead, make sure your

I jumped the gun on assuming there was something wrong with the camera and edited my original post. I guess I got complacent with camera settings. I set up my other eight cameras two years ago with good images in the initial settings. I applied those settings to this new camera. The image is looking better now after changing to CBR/higher bit rate. I will check out the frame interval next to see if it has any effect. Thanks.
Actually, I haven’t sent the first one back. May be looking at what other camera I can replace.

That's great! I was under the impression from your first post that said you received a replacement that you had sent it back and came here for advice after the replacement exhibited the same behavior. Glad to hear you aren't one of the many that quickly return cameras thinking it is broke (when it was just a wrong setting) and thus increase the costs for the rest of us because vendors have to deal with cameras that they might not be able to resell. Now if there is a problem, yeah go for it.
I am sure you will find an older camera location to replace or add a camera to your system with this great camera!
