    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...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Ahhhhhh ... so I am being a numbskull! ;-) All this time I thought the the Ethernet cable to the camera would carry BOTH data and PoE ... but that is NOT the case ... as only data is carried there ... and only the 12V splitter has power. Well that's a bummer ... since I think it's easiest...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Yea, that would be awesome. I agree it seems pretty darn straightforward. I.e. Just take the existing PoE cable from the powered injector/switch and plug it into the female end of the splitter. Then plug the camera into the male end ... and use the 12v pigtail to power the microphone. Heck...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Yea, duly noted those don't look too weatherproof plus they are much bigger ... which is why I ordered the Anvision ones ... which appear to be a bit more weather resistant. I'm just puzzled why @icpilot posted here that he is using the exact same Anvision splitter and reports that "The Anvision...

    PoE Splitter/Adapter of choice to power IR illuminator?

    Thanks for the great info @Teken ... and assuming I want a 12V output, it looks like the model number is PS5712TG which is on Amazon. BTW, if I zoom in on the ethernet cable, it's not clear if all 8 pins are wired (?) But if you say these ROCK, that good enough for me and I can give it a shot.
