Sensors used in Dahua cams
That would be almost impossible today, because Dahua is no longer providing any info if the sensor is Sony’s STARVIS. I believe, for the past few years Dahua has switched mostly to Chinese sensor manufacturers. I really doubt, there is any Sony/OmniVision sensor in recent Dahua camera. Right now... -
Worlds First Review - Dahua DH-IPC-HDW5849H-ASE-LED / IPC-Color4K-T - 2.8mm Turret
Issue 6 seems to be a matter of bad camera focusing. Your 4K-X looks like it is soft at infinity. The 4K-T looks fine. -
Dahua 4K for low light night vision
4K-X is at this moment the best on the market. Read the review of it here: https://ipcamtalk.com/threads/dahua-color-4k-x-in-depth-review.58999/ -
Dahua Color 4K-X in-depth review
@CCTVCam Extra tests? I haven't added anything else since publishing this review. I've expressed myself wrong. I don't think the 4K-X was the worst on COLOR out of all three cams, but it was definitely not the best one. Yes, the sentence "To me the 4K-X wins in all modes." shouldn't be there... -
Dahua Color 4K-X in-depth review
@CCTVCam You are right. I did it because I compared these camera as a whole, not just sensors itself. Thus all parameters matter. Resolution also. If this was only sensor comparison, I would have to omit for example lens brightness. The fact that 4K-X is better at night than 5442 and 4239... -
Dahua Color 4K-X in-depth review
Hi everyone, today I present you a review of recently announced Dahua Color 4K-X camera. This is a 4K resolution model with ultra bright f1.0 lens and huge 1/1.2” sensor. The combination of bright lens and such big CMOS, promises excellent image quality both in broad daylight as well as at... -
Dahua T5442T-ZE in-depth review
Hi guys, Today I present you a review of Dahua T5442T-ZE. This model is equipped with 2.7-12mm zoom lens and an excellent 4 megapixel 1/1.8 inch CMOS sensor. Compared to 5442TM-AS-LED and 5442TM-AS models, which I’ve already reviewed, this one has twice as much RAM available. The housing is... -
Review of Dahua NVR5208-8P-4KS2E + Dahua HFW7842H-Z cooperation
I hate to hear my recorded voice. And my spoken language really sucks. Just turn down the volume if you can't stand it ;) -
Anyone interested in reviews of other brands?
@john-ipvm Sure I've seen them. Otherwise I wouldn't dare to give an opinion. You've got plenty of tests and reviews, but to me these are superficial. The thing is, you never go beyond your procedure. It's always... this camera is behaving like this in our hall test, and like this in our another...- wopi82

Common issues with camera image
Exactly :) Shutter Priority and Manual mode will work the same, only Manual gives you an opportunity to restrict gain scale. -
Dahua T5442TM-AS quick review
It's a video file (done in After Effects) converted to GIF file in Photoshop. -
Multiple camera low light test
@Riclyo I think this is kind of self explanatory :) Your eyes work the same way. The less light you have, the less detail and color you see. At very low light levels you can only distinguish shapes and no color (due to human eye structure, first you lose ability to distinguish color)... -
Common issues with camera image
@wittaj It's exposure time (shutter) expressed in milliseconds instead of fractions of a second. One second is 1000 milliseconds (ms). And so 0.5 of a second is 500ms, 1/100s is 10ms, 1/1000s is 1ms and so on. If I set shutter parameter to a fixed value like 40ms, the camera will only use a... -
