Can anyone help with info on PoE fisheye cameras for use with Blue Iris 5?

I'm trying to achieve maximum coverage of the interior and perimeter of a small (1,000 sqft) house on a 12,000 sqft lot. I'm hoping to keep the cost below $1-2k total for 2 interior and 2 exterior cameras, if possible. I plan to add dedicated identification cameras at entry points, so the fisheyes will be used mainly for monitoring and observation, and possibly to trigger other cameras. There is a fair amount of wildlife in the area, but minimal foot traffic, so the ability to distinguish between humans and animals could be a plus.

Dahua seems to have a handful of cameras that look interesting, but I haven't been able to find much info on how well they work with Blue Iris (Fisheye Cameras – Dahua Technology USA Inc). The 5MP N55CT5 appears to offer what I need for indoors, but for the exterior areas I'm not sure whether the 8MP N88BR5V provides a significant improvement over the 5MP N55CS5.

I read that Blue Iris can currently only dewarp on playback, not the live stream, so I would like the camera to be able to send separate dewarped streams for live viewing. Even better if it can provide a stream that blue iris will treat as a virtual "PTZ" camera. Should I be looking at different vendors for this functionality? Are there any "gotchas" that I should be aware of when adding fisheye cameras to Blue Iris, or any other important features that I should be looking for?

Thanks for any input you can provide!

Thanks. That looks like an unbranded Dahua N55CT5. Can you tell me a bit about how Blue Iris handles it? Does it provide dewarped streams or a PTZ emulated mode that BI recognizes? Is Blue Iris still limited to dwarping only the recorded footage or can it dewarp the live video as well? How well does Blue Iris handle dewarping in either case?

That is actually a Dahua OEM International version. It is the same as the equivalent model from Dahua and can have its' firmware upgraded safely. I bought from Andy at EmpireTech, a member here, he stands behind what he sells and also gets firmware modified by Dahua based on requests and critiques provided by members here. He also has excellent pricing compared to buying from an "authorized" Dahua dealer assuming they'll sell you one camera.

Thanks @sebastiantombs. I will likely buy from Andy, but need to first understand whether the camera is likely to meet my needs. Can you provide any info on the streams that the camera can provide and how BI handles the video? That's what I'm trying to find out but I've not been able to find any specifics online. The datasheet only says that it offers dewarping modes when "connected to an NVR or a DVR that supports dewarping methods." It's not clear what this means for an NVR like Blue Iris that only supports dewarping during playback, or whether it only works when connected to a Dahua NVR.

I think there's a review of the camera from Andy somewhere here, probably in the Dahua thread or Andy's thread. I know there are a couple of threads that mention this camera and how it performs. I think you could contact Andy directly to get the information you're looking for, but my guess is that BI won't dewarp the live view.

I just opened the box, hung them up, and set them to Auto.
I aint got no DeWarp factored in.
I'd have to go thru the menu's at work Monday.
and see if Dewarp is on the Device, and/or on the Blue Virus.
I mighta played with a setting or two after I had them up for awhile :)

I have this unlucky gift of Gait recognition, I can tell which resident it is by thier walk, I honestly don't remember If I dewarped anything, the doors in the pics look pretty straight, all things considered.
I'm mostly interesting coaching the non compliant residents not to throw cardboard boxes down my trash chute.
and to return the Shopping carts to the parking garage.

Thanks, everyone. Based on the review that @EMPIRETECANDY linked to and other bits of info online, it doesn't look like these cameras have onboard dewarping function or the ability to send separate dewarped streams to BI. It appears that BI can provide a dewarped panoramic view during playback, but it can't dewarp the live stream or export a dewarped clip. I found an old post from Dahua about a firmware update to provide on-board dewarping in their "DH-IPC-EBW812A0N" and "DH-IPC-EBW86A0N" models (I can't figure out their naming scheme), but it looks like even on those, the camera combines all of the dewarped views into a single stream, rather than providing multiple streams with one view each.

I have seen the features I'm looking for in videos for cameras from vendors like Uniview, but from what little information I can find, it seems that these dewarping and PTZ features also require an NVR from the same vendor, so they must not be built into the camera and therefore wouldn't be available in BI.

I think I may need to keep my eyes open for a camera with onboard dewarping, or maybe there is some sort of dewarping utility that can process the stream before handing it off to BI
