I'd like to monitor an area about 100 ft from the camera, about 50 ft wide. At night, 1 street light nearby, color not necessary (can be IR / BW). I don't think I'm interested in anything larger than 4mp, but I probably need some sort of vari-focal. I believe the IPC-HDW2441T-ZS would fit the bill, but I don't see it mentioned much around here. Is there anything else that fits this bill?
Any comments (or maybe better alternatives) for IPC-HDW2441T-ZS

4MP on a sensor smaller than what is good for 2MP is why you don't see it mentioned much around here.
If you want 4MP, the go to is the 5442-ZE (54IR-ZE), but keep in mind that will not IDENTIFY at 100 feet. But if you wanting to just monitor, it would be ok.

Is there a varifocal 1/1.8 4mp?
You know what, I probably don't need 4mp. 2mp would be fine in a 1/2.9 if it had the same (or better?) low-light performance as a 4mp 1/1.8. But it has to have the zoom I want.

A camera that I have now that I think has good night vision (or maybe I should say, good IR vision with external IR flood) is the IPC-HDW2431T-AS-S2 (4mp 1/2.9). I see that it currently costs about $80. The IPC-T5442T-ZE is $195 (but it has zoom).
Is there a 2mp version of the 2431 with 1/2.9 sensor that has better night vision and zoom?
I guess the HDW2441T-ZS would be equivalent in night vision / IR vision to my HDW2431T-AS-S2?
Probably a topic for another thread, but what is the current state of these cameras in-camera motion detection when it comes to rejecting lightning, snow or rain?

Everyone's idea of "good night vision" is relative.
Is your good night vision a static image or an object in motion?
Please post an example of an object in motion from this camera that you think has good night vision.
The 2MP you would want would be on the 1/2.8" sensor, which would be the 2231 (22IR) ZE

Not that I can add anything useful to what is already posted, but it would be helpful to know what you are trying to achieve for the area in question. What is the purpose of the camera, detect, observe, recognize or identify?

This is single frame from a recent motion-detection capture from my IPC-HDW2431T-AS-S2. I think this was a bat. It's been a cold April here, colder than normal. Ambient temp was probably 35 - 40 F. This was 1:18 am.
This was the main stream, substream is disabled. Encoding mode was H.264, smart codec off, resolution set to 1280 x 720. So I am not streaming / recording at full resolution. Frame rate is set at 8 fps, variable bit rate, quality is 6 (best). I-Frame interval set to 16. This bat entered the frame to the left of this position (about where the first car is parked) and appeared in a total of 4 frames. There is an IR flood light wired to an aluminum gutter that runs horizontally along the wall on the left, it points directly at the boat. This is a flat chip array IR (3 rows of 10 LED's) with no shielding or hood, so it's dispersion is probably quite wide. There are no visible lights illuminating this parking lot. If you were there, it would be pitch black. There is another IR light around the corner, it's light is visible in the distance.
This was captured in the camera, using in-camera area-based motion detection grid settings. An e-mail of the trigger frame was sent to me by the camera, I went to the camera to obtain the full video clip. The video clip is 24 seconds long, with 3 seconds of pre-detection video.
I tweaked some camera settings. Changes I made - Backlight mode was off, now is BLC. That brightened things up. Exposure shutter is now 1/60 (it was auto I think).
I've scaled these down to 50%. Here is a current image capture:
I can remotely turn off the IR flood. Here is how it looks with the closer IR light turned off:
There is a full moon out tonight, I don't know if it's still visible or not. The IR flood around the corner is more visible. Oh yea - I have the camera's IR lamp always turned off. Not using it.

Just my thoughts, as I am still learning, so take what you can from it.
Obviously, a single camera with little available light isn't going to get much coverage or see a whole lot. I have drawn zones over your still capture to what I "think" might apply to detect, observe, recognize and identify activity.
Green would be the Detect and observe zone, you'll detect and possibly observe activity, but you really won't be able to get much in the way of details.
Yellow would be the recognize zone to where you can make out some details of the activity
Red would be the area which you could possibly identify the activity.
All other areas NOT in a zone here probably won't get much of anything.
Again, these are just boundaries based on what I see in the still you provided, so not really accurate. To get a more accurate idea, I would go out and walk around the whole area to see where these zones are, based on a real target.

I posted the pics because someone wanted to see an example of low-light (or IR-illuminated) motion blur of my 1/2.9" camera, which caught a respectible few frames of a bat flying through.
The T54IR-ZE-S3 (1/1.8" sensor) is priced at $195 (currently sold out on IP Camtalk store) and the HDW2441T-ZS (1/2.9" sensor) is available from one amazon vendor for $129 and quite a few ebay vendors for around $180. It seems the availability and price of the HDW2441T does not make it a competitive choice against the T54IR-ZE-S3. The actual availability of either camera is (to me) unknown.

It really hard to say what camera will "fit the bill" without knowing what subjects and activity you are trying to capture.
Ok, so definitely blurred, but I can't think of any camera that it wouldn't be blurred on. So, let's go back to the basic question again, what are you trying to capture here. Knowing what activities and subjects you are trying to capture will go a long way to making an informed camera decision
That really isn't a fair representation image of the camera as it is in close quarters and a ton of IR bounce is coming off the boat cover.
It will respond completely different if it were in an open area without IR bounce off of close objects.
I generally agree with JPMedia summary of the zones and what you would capture.
I have a 4MP on the 1/2.8" and I have a decent amount of light and some IR blasters and it won't reach 200 feet, barely 100 feet.
Here is the 4MP on the 1/2.8" sensor. That box is 52 feet away and you can see how dark the rest of the image is. It drops off fast. Shutter is 1/60.
This camera shows you how much light and IR I have in that area with a default shutter.
In my case, I have no IR bounce from a close object that greatly helps illuminate the area.
It has also been requested several times, what is your use case/goal for the camera location - that can greatly impact the camera choice. Detect and Observe is one camera as it can run on default/auto while Recognize/Observe is another as it will run faster shutters.

There is a small office complex across the street (in these images it's to the upper-right and not visible from this camera). For some time, perhaps more than a year, for a few nights a week a car leaves this parking lot at some wee hour of the morning. The headlights shine across to my lot when it's leaving, and that triggers the detection in this camera. The captured video shows the headlights through the hedge, I can see it creep slowly out of the that lot and turn either left or right. I want to set up a temporary camera (at a different location) that would be able to see across the street into that lot and give me some idea if this is a cop car or civillian car, and whether or not it entered the lot a few minutes before it leaves or a few hours (I never see it enter the lot but then again it's headlights would be facing away from me so I wouldn't see that). I could configure a camera looking at that lot to be able to trigger on any car entering or leaving. I'd only be interested in maybe 11 pm to 4 am. Very quiet around here generally at that time.
If you go the 54IR route, we suggest either direct from EmpireTech or his website or direct. Who knows when it will be available here.
The 2231 I linked that is on a slightly better 1/2.8" sensor is $6 cheaper than the 2MP you are looking at.
I can assure you the 2441 would be no match with the 54IR.
Having played with these things for a long time, the larger sensor makes a huge difference.
The 2MP can get away with items closer to the camera or with IR bounce like inside, but the larger sensors will perform way better outside with open views.
