Hey @EMPIRETECANDY - I have some of these cameras at my old house. What would you suggest as updated models for this camera for my new house? Or is this the latest model and just stick with it?

These are still the king of the hill, especially if you need infrared.

While newer, the 4K/X is an incredible full color camera, but does need light or use the white led on it. But they don't have a varifocal version.

Perfect! Thank you

Great to know you will move to new house, the T5442T-ZE still be very good, if want to get a 4K version with IR check the IPC-T5842T-ZE, it's working great too after the new fw update.
If place has some light in the night use the IPC-Color4K-X bullet or IPC-Color4K-T, they are full color killer cameras now!

Any chance @EMPIRETECANDY we'll see a varifocal version of the 4K/X coming down the pipe?
A varifocal with F/1.0 lens and 1/1.1.2" sensor would be a killer product.
Even more so if "just" 2MP (which works since you can frame precisely) which means the pixels would be huge and serious light suckers!

 

[bigredfish]

Don’t think you’ll see a VF anything with F/1.0, that’s one of the advantages of fixed lens

 

[sebastiantombs]

And if you see an F1.0 varifocal bring your checkbook and first born young to pay for it.

 

[alekk]

At a recent Hikvision webinar, they talked about the DS-2CE79DF8T-AZE ... which has nice specs: Vari-focal, 2MP (works since you can precisely frame things), F/1.0 lens, 1/1.8" sensor ... so that's pretty darn close!

And I believe the price point is "reasonable" ... BUT ... it is a Turbo-HD product, not a Network Camera ... darn!

 

[sebastiantombs]

Bet the F1.0 is at 2.8mm only. At 12mm it'll be close to F2.0.

 

[EMPIRETECANDY]

Currently low light camera 2mp, 1/2.8cmos are bit good to go for low light place if budget is limited, like the IPC-T2231T-ZS, IPC-T3241T-ZAS.

Hi Andy can you list the differences between IPC-T2231T-ZS, IPC-T3241T-ZAS. Thanks

Ah just found looneytoons review for the IPC-T3241T-ZAS and also statement that the IPC-T2231T-ZS does not have audio.

How can I check what the zoom level of this camera is equivalent to focal length in mm? I'm trying to use this camera to help me establish what focal length I need at different areas so I can buy fixed lens cameras.

I was hoping there would be a way to find this on the camera itself, but so far no luck:

 

[IReallyLikePizza2]

My view is that you should just get all varifocal cameras. So often I've been set on a view, and then in the future realized that moving it to the left and zooming in makes more sense. Often its because I've moved something that I'm focusing on, or something like I've added a tree etc.

Not a single one of my cameras are on the same zoom level as when I first installed them

 

[mephisto_uk]

I was informed in another topic about Focal Length Calculator

My idea with fixed lens is to get the best quality possibly where I've settled for the focal length. I read somewhere the quality of image on varifocal decreases a bit compared to a fixed lens.

By the way, what a difference between my crap Unifi G3 Flex and the IPC-T5442T-ZE as it gets darker. I'm so pleased!

Set the Zoom Speed to '1'. Hover your cursor over the slider and a value will pop up. This is the current setting.
Move the slider to the far left to get the minimum number, and to the far right to get the maximum number.



Go to the calculator that you linked to and use these numbers.

Realize that for the 5442 cams, the fixed lenes are on a different mount than the varifocal cams. Which means that the calculated value will not be the exact value of the fixed lens version. I did a test of this in the following thread:

Comparison of a Fixed Lens and a Varifocal Lens Camera's FOV

I was testing out a new Dahua T5442T-ZE 2.7-12mm Varifocal camera (from @EMPIRETECANDY ) and was going to compare it's performance to the Dahua HDW5231R-ZE and the HDW5431R-ZE cameras, which are 2.7-13.5mm varifocals, along with the T5442TM-AS fixed lens at 6mm camera. The HDW5431R-ZE has been...

What I have found is that the fixed lens versions have slightly better specs, but I do not think that this translates to a better image that one can see in real life.

 

[bigredfish]

It depends

Granted this comparison is 3 years old when the 5442's were fairly new, but Ive seen same with other models. I generally use fixed focus camers where possible but there are plenty of cases where having a VF is quite handy

See post #26
Review: Dahua HFW5442T-ASE 4MP Starlight+

 

[bigredfish]

I think it’s mostly about F Stop

With the current 5442 VF MAX aperture is F1.8
The fixed is F1.6

Again not a photography expert but the MAX aperture assumes 2.7mm focus in this case on the 2.7-12mm VF. As you zoom, that number increases. (Lower is better) so at say 6mm the FStop might be 2.0?

With higher zoom PTZs it becomes more obvious, and the specs typically give the aperture range based on zoom

Example:
On my SD6AL433XA-HNR

Max. Aperture

F1.5–F4.8
