    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Yep - you gotta have SOME light! ;-) Just to be clear, when you say "But with the same amount of illumination, the Z4E comes close to the 4K", you are referring to visible light comparison - not B&W infrared on the Z4E- right?

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Can you expand a bit more on this ... particularly WRT to low-light quality? I.e. if you put the Z4E against a 4k-1/1.2" sensor camera, how would they compare WITHOUT illumination ... and NOT putting the Z4E into infrared mode? I certainly agree that a BIG WIN for the Z4E is using the optical...

    Mini-Review - 5442-ZE-S3 AKA T54IR-ZE-S3 - Replacement to 5442-ZE

    Thanks @wittaj and @Parley for the low light impressions and that sounds pretty encouraging. @EMPIRETECANDY - any comments from your experience and/or the factory about this significant improvement ... and similar advances being applied to upcoming products?

    Mini-Review - 5442-ZE-S3 AKA T54IR-ZE-S3 - Replacement to 5442-ZE

    Assuming I'm reading the specs correctly, this F/1.8 and 1/1.8" sensor camera has comparable low light capability (Min. Illumination lux) as the the IPC-Color4K-T ... which is F/1.0 and 1/1.2" sensor. It would be interesting to see a real-world comparison since IF SO, this would be quite an...

    Dahua Visit at Oct.12th and 13th

    Ditto that one can hope it is there ... with F/1.0 lens ... ;-) The pole with dozens of camera's on it is pretty hilarious!

    DS-2CD5526G0-IZ(H)S

    Here's a shootout I did back in 2018 which is when the 5526 first came out ... and that camera has been used since to Watch Grass Grow! ;-) Note that I'm (currently) using 1/6s shutter speed at night ... so that's why the image looks semi-decent (common "trick" by the vendors to show how they...

    DS-2CD5526G0-IZ(H)S

    I've had a 5526 for several years and am generally pleased with it ... but one can always hope for more low-light capability ... although 2MP in a 1/1.8" sensor (the lens is F/1.2-2.5) should do really well since it will have large pixels. I like the vari-focal since you can frame the image...

    Dahua WIZMIND X SERIES

    Even without the over-saturation, that literally is a Disney show - well done @patc WRT night footage, have you tried NOT allowing the camera to go into IR mode and is there any chance of capturing stuff with a decent frame rate?

    Dahua WIZMIND X SERIES

    You are sharing (and figuring out) some great info @patc - thanks. Any chance you share some nighttime footage with camera settings?

    Dahua WIZMIND X SERIES

    That's really impressive @EMPIRETECANDY ... curious if the aperture/iris/F-Stop was held constant as it didn't appear that the light levels changed on the zoom in/out. BTW, if you put that 1/1.2" sensor in a HDBW7442E1-Z4-X (less MP makes for bigger light sucking pixels) and want a tester, I'd...

    Dahua WIZMIND X SERIES

    Just to provide an example of what I wrote earlier, I looked up the specs of the SD8C845FG-HNF (nice San Diego skyline - although quite a bit of noise reduction in that image) and it says "Color: 0.0005 [email protected]" ... but because it's a BIG zoom (8 mm–360 mm), the Max. Aperture goes from F/1.5...

    Dahua WIZMIND X SERIES

    Great point ... and yes, I have noticed that on SOME camera's, they'll show the min/max FStop. Wouldn't it be nice if all the vendors showed a common set of data with agreed upon measuring methodology so one can reasonably compare ... WRT Zoom: As you increase the focal length, to maintain the...

    Dahua WIZMIND X SERIES

    Yep - "F/" is "F/" ... ;-) And also agree the minimum lux (as you pointed out well earlier) doesn't mean much without a shutter speed, etc. specification. But I just found it confusing why within those same-family of Dahua cams, that there wasn't more of a difference ... unless the measuring...

    Dahua WIZMIND X SERIES

    Great discussion. As a photographer, I'm somewhat familiar with the effect of aperture, shutter speed, and sensor size (and mega-pixels) on light gathering capability. Sensor technology also plays a role and it sounds like Wizmind X series is a step up in that department ... although not quite...

    5442 end of life?

    Ditto all the other comments that have 4K on 1/1.2" sensor (or 1"!) with varifocal on their Christmas wish list! ;-)

    Review-OEM Loryta IPC-T5442T-ZE Varifocal 4mp camera (Dahua)

    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...

    Review-OEM Loryta IPC-T5442T-ZE Varifocal 4mp camera (Dahua)

    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!

    REVIEW: HIKVISION DS-2CD2387G2P-LSU/SL

    That's an AWESOME "Dunkin Doughtnuts" story Chris - I can only imagine how much "eye-rolling" my son would have done if I had said "lets talk to these Hikvision people" ;-) Thanks in advance for the review - that's a pretty nifty camera. And yea, my experience with my Hikvisions is that IE...

    Hikvision ColorVu + 4K (DS-2CD2087G2-L)

    Ditto a varifocal with the 1/1.2" sensor or larger ... combined with F/1.0 lens and latest sensor technology that doesn't have too many megapixels. A LOT of those would be sold!

    Long Time Listener, First Time Caller - Dahua/Empire 4k Color Cams

    LOL @Kevin Doe when you commented "Any lower and all the cameras would have to be installed on either brick walls, or vinyl siding, a situation the wife would certainly not go for." Speaking from experience, WAF (Wife Acceptance Factor) is a very significant issue that has to be...

    Unauthenticated Remote Code Execution (RCE) vulnerability in Hikvision IP camera/NVR firmware (CVE-2021-36260)

    FYI FWIW that I tried the script and it worked great once I installed the required software/modules on my CentOS box - thanks for the quick confirmation test!

    Dahua Color 4K-X in-depth review

    Thanks for the info @wopi82 and I don't mean to hijack your (excellent) camera review thread, but you got me looking around and I found this Sony page that shows their various security sensors with links for more info - I'm sure you already know about it. That IMX482 appears to actually be a...

    Dahua Color 4K-X in-depth review

    GREAT review @wopi82 - as a Canon shooter, I especially appreciate that comparison and your using the exposure triangle to make apples-to-apples comparisons. That IMX585 sounds pretty impressive and the "70% better NiR quantum efficiency – at 850nm" should make for even cleaner B&W imaging, but...

    Anybody tested the first vari-focal Hikvision ColorVu's: DS-2CD2747G2-LZS (Dome) and DS-2CD2647G2-LZS (Bullet)

    I saw that Hikvision has added their first vari-focal ColorVu cameras - DS-2CD2747G2-LZS (dome) and DS-2CD2647G2-LZS (Bullet) - curious if anyone has tested them yet? These are F/1.0 lens and 1/1.8" sensor with 2,688x1,520 resolution ... so should be pretty decent in low light. But I think...

    Funky problem upgrading firmware on DS-2CD5526G0-IZHS

    So an update on this thread from a while ago. Recall that the problem is I have a fairly early model Hikvision DS-2CD5526G0-IZHS that routinely "took" firmware upgrades to 5.5.91 ... but then would not take 5.6.0 ... or 5.6.10 ... or 5.6.12. Just for grins, I tried downloading them again from...

    Unauthenticated Remote Code Execution (RCE) vulnerability in Hikvision IP camera/NVR firmware (CVE-2021-36260)

    Thanks @watchful_ip ... although I was surprised that Hikvision has recent firmware for that G1 - link to European Portal (and release notes there show it applies to the 2735). Another camera I have is the 5526G0 ... which I believe (?) is in the H3 family. That also appears NOT to be affected...

    Unauthenticated Remote Code Execution (RCE) vulnerability in Hikvision IP camera/NVR firmware (CVE-2021-36260)

    Wooooo ... as a network/security admin in a previous life, this is some serious sh*t ... That is an EXCELLENT report @watchful_ip - well done ... and the community (and hopefully Hikvision) thanks you. It's a bit confusing trying to figure out exactly what models/firmware is affected. For...

    PoE Splitter/Adapter of choice to power IR illuminator?

    I agree that powering the camera via the 12VDC would be plug-n-play ... but it would equally be so if one were using a splitter like @tigerwillow1 mentioned ... that actually does pass power (and data of course) through the Ethernet cable. However, the Anvision does NOT ... so that's the answer...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Actually, because the microphone has a pass-thru 12V, I don't even need a 12V splitter if I use that very viable solution of using that to power the camera. The two questions I'm trying to answer are: 1. Does the ANvision "remove" power from the Ethernet and only pass thru data? I'm pretty sure...
