SD22204T-GN vs SD29204S-GN

I purchased these 2 cameras a month ago and they just arrived. I started to play with the cameras and I noticed there are quite a bit of quality difference between the two.

On paper, they seem to have the same sensor maybe because 22204 has a dome on top it makes the image less clear than 29204? On 29204 I get a very clear crisp image but 22204 the image is less desirable (still good but not ad good)

Now, I know i will need the IR from 29204 because I need to put 1 of them outside to monitor my door. But 29204 does not seem as weather proof as 22204.

Other than these 2 things I think the 2 cameras a pretty much on par. Can anyone comment on if 29204 is safe to put outdoor (could be exposed to snow or rain) because I don't feel 22204 without IR can do the job for my out door camera.

Thanks

Yeah I read nayr thread and decided to buy one to try along with the 22204 to see the difference between the two.

What model would you recommend to put outside with exposure to rain/snow and IR capabilities? I think all 22204 missing is the IR for me.
 
take the dome off and see if that helps, might just need a good polish of the dome.. but if there is any lighting on the dome it can cause issues.

are they both configured for the same bitrate settings? the defaults might not be the same between the two.

the weakspot of the mini black face is the top of it, if you can keep water from getting to the top I think it'll do fine outside..
 
Don't believe in what sellers tell you or post on their websites, believe in specs posted on Dahua website.

There is no mention of Sony sensor on these two models by Dahua:
SD29204T-GN(-W)

SD29204S-GN(-W)

I see the "S" line is a 1/2.8" sensor and the "T" line is 1/2.7" sensor. I assume the 1/2.8" is better?
 
I also took off the cover and set the bitrates to be the same. The cameras are not the same quality. This could only lead to different sensor within the camera.

but of course there is no IR sensor

I believe the 22204 has an IR cut filter and sees IR lighting, but doesn't have IR lighting. You could add external IR lighting.
 
These are the specs for SD22204T-GN.

As a general answer regarding sensor size:
the smaller the sensor is, the less light it will capture (so less sensitive). Also, at the same resolution, a smaller sensor might show more noise (especially during the night). Also, there might be a difference in the horizontal and vertical angles, depending on the optics.

I found this video on youtube of SD22204T-GN which does not have an infrared illuminator:

I have to say the video does not look bad, to my eyes it looks good.
 
add some IR flood lights on important targets and chokepoints.. alot of people find external IR is preferable to built in IR because it keeps the bugs away from the lens and wont lightup rain/fog/dust as badly.

or add some visible lighting, its cheaper..
 
the mini black face has 360 degree rotation, [TABLE="class: ke-zeroborder, width: 100%"]

the dome has 355 degree rotation, so not quite full 360.

With high zoom PTZ's you def want onboard IR, they usually have multiple channels with wide and narrow focus that turn on/off as you zoom in.. no need to have a 45 degree flood light when you have a 5 degree FOV and vice versa.. but with under 12mm optics, its well within the range of most flood lights so external lighting w/a PTZ should not be too much of a problem.. the mini black face has a dimmer on its IR that gets brighter as you zoom more, but its all flood lighting (vs spotlighting)
 
I too believe the image quality difference is between the sensors that is offered. I am considering to add in sensors to my doors so that when people approach, it turns the lights on so that way I do not have to deal with no light.
 
You are probably right as you know more about Dahua. But that first link you sent doesn't say Sony Exmor.

Also I've seen lots of adverts for IMX222/322 back when I was first buying these types of cameras and they all varied from 1/2.7" and 1/2.8".

It's odd that Dahua don't advertise that as they do advertise it on other models.
