    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 lux@F1.5" ... 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...

    DITTO ... or better yet, how about the super-light-sensitive 1" Canon SPAD Sensor! ;-)

    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...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Ummmm ... I'm probably not explaining this well - sorry about the confusion. First, the Hikvision certainly has 12VDC in to power it which can be used to power the camera. My current setup is PoE injector to Ethernet cable which plugs into the Hikvision - provides BOTH data and power. And I...

    PoE Splitter/Adapter of choice to power IR illuminator?

    First, I'm super-appreciative of everyone chiming in ... thanks a bunch! Yep - I realize since that microphone has a 12V pass-thru, I don't need to further split. And sure, I could use that 12V pass-thru to power the camera, but now I'd have to add another cable into the camera itself- I was...
