Hello everyone,

I'm pretty new to the whole topic of cameras.

I initially wanted to buy a Reolink system, but after a lot of research I came across Dahua.

Now Dahua has what feels like 100 different models.

I'm looking for 6-8 cameras to hang at a height of about 7 meters and monitor the whole house. This involves a large garden, the front towards the street and the entrance area.

I have currently come across the Dahua - IPC-HDW3841TP-ZS-S2 - IP - Eyeball model, which actually looks really good with 8MP.

Can you tell me something about it or do you have any better suggestions?

Basically, I like the eyeball version looks, as it doesn't stand out so much.

Please forgive me if I don't know everything in this field. I would really appreciate any explanations as to why these or other cameras are better.

Thanks to everyone in advance.

Not too good, just use the IPC-T54IR-ZE s3 4mp for very low light or 4K IPC-T58IR-ZE s3 if normal light at night

those are Dahua 5442-ZE / 5842-ZE sold under different much cheaper brand (Dahua OEM).
The same hardware / firmware / features...
very popular here on the forum...
54IR-ZE is most popular cam here due very good quality, good night performance, lots of AI and best value for the money...

Yes. Same exact cameras with a different sticker. EMPIRETECANDY is a direct supplier favored here. I’ve been buying from him since 2017 or so

The 5442 series (T54IR-ZE s3) is the go-to camera for most of us

there is difference.. if you have some street light, 54IR will work much better in color...
if there is no light, then You will run on IR (infrared light from camera) and in this situation difference is small..

Thread '8MP IPC-T581R-ZE-S3 fuzzy view'

Hi,
I decided to renew my 10 year old cameras and ordered some from Andy, I have the 4MP IPC-T541R-ZE-S3 and then ordered the 8MP IPC-T581R-ZE-S3 as I thought the 8MP would give me a better clearer view.
I have spent a few weeks trying different settings and resetting the 8MP camera various times but cannot get rid of the fuzzy picture, the 4MP works with default settings in most places (except I set night to colour and it works fine).

Here is the same time screen shot from both cameras, the first one is the 4MP and is nice and clear, however the second pic is of the 8MP and is fuzzy...

thanks alot again. one more question. i would go for the 4mp cameras. how about the nvr recorder. there are 2AI and AI recorder. whats the difference?
 
there are the same (Dahua NVR52xx-EI)..
Andy have a little mess with NVR naming...
in theory this digit before AI informs about HDD count, but for some reason some 2HDD NVR are called simply AI without 2..

You have 8/16/32 channel models, some with POE switch (8P or 16P), some without..

One Last question haha.

IPC-T54IR-ZE-S3. vs EmpireTech IPC-Color4K-T 8MP 1/1.2" CMOS Full-Color Vs. EmpireTech IPC-Color4K-T180 4K Full-Color 1/1.8"​


the Camera would hang around 7-8 Meters under the roof. Is there any benefit which makes the Full-Color cameras superior? Or would you Recommend the Full-colour instead of the t54ir-ze-s3?

Unfortunately they have no Zoom. It might be to Long distance without zoom at 7-8 Meters height or?
 
Are you saying the camera would be 7-8 meters high?

In that case, you are getting OVERVIEW and not IDENTIFY captures with those cameras.

You have lost the entire IDENTIFY distance in the vertical.

Th 4K-T suffers from a narrow focus range of about 15-18 feet and anything shorter or longer than that will be soft/blurry.

But at 8 meters high, there will be no IDENTIFY with a 2.8 or 3.6mm camera anyway.

so the only real option is the IPC-T54IR-ZE-S3 becouse of it zoom to 12mm? or is even that not that good for that height?

might be better to go with 8mp to have better image while zooming?
 
No, you need to lower the height of the camera
 
Yes, the 7-8m the ivs will not accurate, too high, normally 3-4m is the best height, or else use the big zoom cameras or PTZ.

Hello Andy, i wrote you an mail with pictures from our house. maybe if you have time you can check it. wrote it to sales02@empire.....com. thanks alot
 
Digital zooming only works in the movies and on TV.

You can get by with a little, but not a lot, and the ability drops exponentially at night.

See this thread where someone was upset that the difference between 8MP and 3MP digital zoom wasn't better. And this was a perfect situation of standing still in the middle of the day.

You need to lower the camera and/or change your expectations of the goal of the camera.

If you can find a pinch point out further in the distance to optically zoom in to, then you can get away with a PTZ or one of the higher focal length varifocal cameras.

See this thread for the commonly recommended cameras (along with Amazon links) based on distance to IDENTIFY that represent the overall best value in terms of price and performance day and night.

Color4K is a toy with a lots of problems (lack of sharpness, heavy digital processing, compression artifacts, underpowered CPU/SOC).. I don't use it in any installations at all.

Color4K-T180 is only overview camera, which don't see IR (only white light). Sometimes I use it in installations where I have very long wall and need to put camera in middle. It have big 2 meter half circle dead spot under camera. For 7-8 meters height very bad idea....

54IR-ZE (plus telephoto version 54IR-Z4E) - 90% used by me for installations cams are 5442 (54IR) in different versions.. most universal (different versions, different lenses etc), very good at night (with some street / garden lighting), huge AI functionality, best value for the money cam..

is there any chance to install those cams lower?
you can use bullet and mount to horizontal wall lower (but you need there cat5 cable)...

in case of installation at 7-8 meters You will have very big problems with human faces.. people which will be 5 or less meters from camera, will be captured from up (top of heads not face)..
that camera height will only work for people at LONG DISTANCE from camera (but then face details will be small without optical zoom).

if 7-8 meters is the only option, to have chance to record faces You will need to mount / direct and zoom those cameras for places at distance (opposite side of bulding/area) around house...

normally You mount 2 overview cams in front of building - on left and right side.. both cams record overview at 90-110 degree horizontal and records people under camera. Both records all front of building plus everything which is in front of house.
With those overview camera You can Identify people from 4Mpx cams up to around 7 meters and Recognize up to 14 meters (DORI distances from camera spec sheet). For more You install third camera with strong optical zoom (Z4E) directed at entrances.

in You case You must mount 2 very zoomed-in cameras which will record only opposite sides of building (from center to the end) plus much smaller area in front of building. Plus third camera above entrance which will be directed/zoomed into plot entrance.

With 7-8 meter hight installation directing camera at places AT DISTANCE from camera (and using strong optical zoom-in) is the only method to record faces from front side of people (not up side).
Recording people at distance is the only way to lower angle from which camera captures people / cars..

For that You will need probably 54IR-Z4E model (which have optical zoom 3x-9x - 45 to 15 degree horizontal FoV - this is not overview camera), which is only available as bullet or dome (there is no turret option - optics is too big for turret).

Even with that, You installation have worse characteristics as typical one done at 3 meters height.
