    DS-2CD2387G2P-LSU/SL Panoramic 4k

    Have a look on Ebay- there's a Chinese seller with them listed.

    DS-2CD2387G2P-LSU/SL Panoramic 4k

    Interesting. You've got the S22 with the three lenses- not the Ultra- was it taken in 1x or 3x mode? I've got an S22 as well- I would have thought the pictures would be brighter. Although, I do run my 8MP Colorvu at faster shutter speeds.

    2CD2387G2-LSU/LU Tear down and refocus (with pictures)

    In the other photo it shows locator lugs on the lens assy that fit in between the suspect long screw and the glued screw. (Into the black hole which is visible on the copper section.) There's matching holes in the silver bracket. So the orientation appears okay. Perhaps it's just happened that...

    2CD2387G2-LSU/LU Tear down and refocus (with pictures)

    Closest pic of your camera I could find compared to mine. (Light levels played with on your pic to show more shadow detail.) When I looked closely I wasn't so sure that the CCD/ optical sensor could move independently to the lens barrel. That copper bit seems to be more of a heatsink than a...

    DS-2CD2387G2P-LSU/SL Panoramic 4k

    I'm tempted to replace 2 x 3Mp DS-2CD2335FWD-I cams ("powered by dark fighter" Color: 0.008 lux) with the one. I've got them set to colour and use LED floodlighting (in addition to the dismal street lights.) That would free up an NVR channel which would be handy. The one 8MP Colorvu I've got is...

    2CD2387G2-LSU/LU Tear down and refocus (with pictures)

    There was a small amount of glue left on the threads of the lens which made it stiff to adjust- so I didn't bother putting any glue on mine. On some older Hik cams I've done lens changes and used teflon plumbing thread tape to make the lens firm (so you can still adjust it, but it won't move...

    2CD2387G2-LSU/LU Tear down and refocus (with pictures)

    I'm not so sure that's the purpose of those screws as the optical sensor appeared to be fixed in relation to the lens. But there are two screws, adjustable, with locking glue on them. So my camera was substantially out of focus. I moved the lens probably 5 to 10 degrees. Distant objects are way...

    2CD2387G2-LSU/LU Tear down and refocus (with pictures)

    I've got mine apart now. That lens glue is a PITA to get off, I've only just started removing it. One thing I have noticed is the silver metal bracket (the lens module mounts to) has adjustment screws. They are used to mount the lens square to the optical sensor. I've got the LHS of the video...

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    That's the same as mine. You've got 80Mbps total incoming bandwith- so 10Mbps per channel (averaging it.) Increasing the bit rate will improve the picture detail. I did a screen capture (jpg) on the NVR to show the LHS focus issue, it doesn't really show it up as much as the live view on a 55"...

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    Are you using an NVR? With H265+ and H264+ I've always had bizarre issues crop up after a couple of days (corrupt frames etc.) Give H264 a go and see if it's better, do you have enough bandwidth to bump the bitrate up too? My NVR limits me to an average of around 10000 per channel. I don't have...

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    Try out plain H265 and h264. I think I've got mine set to h264 as the detail is clearer. Your bitrate is low for an 8MP camera, but I guess your FPS is lower too. I've got mine set to variable at around 11000.

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    It will be obvious when it's installed if there is the same problem. Mine looks out over my double width paver driveway, it's obvious the LHS of the screen has soft focus no matter what the distance. (When viewing the pavers, tree leaves etc.) It will be interesting to see what you think once...

    Hikvision 4k colorvu acusense turret focus

    3.1m is the closest it will focus (as set up by the factory so the focus to infinity is correct.) As mentioned, the only way to change it- so it is focused at 1m- is to pull the camera apart and adjust the screw mounted lens. It's not something I'd recommend doing unless you're familiar with...

    Hikvision 4k colorvu acusense turret focus

    The lenses are a screw mount and pre focused at the factory. The Colorvu cameras use a wide aperture lens (which lets in more light), but the down side to that is the depth of focus (the distance range in focus) will be reduced. The specs do mentioned the minimum focus distances, for your 2.8mm...

    Hikvision 4k colorvu acusense turret focus

    You can change lenses too. I've done it on some older 4MP Hik cameras, I've run up to a 12mm lens for a long and narrow side path. It would be interesting to try say an f2.0 lens. The depth of field (minimum focus distance) would improve, but the low light sensitivity would take a hit. How much...

    how to set up Hikvision DS 7608 NI-I2 NVR and Hikvision 2CD2047G2 LU network camera for lowest delay from real time live view

    There should be settings on Liveview something along the lines of "Realtime/ Balanced/ Fluency". Unlock the NVR and they're at the bottom of the camera picture when you hover over the bottom section.

    Hikvision 4k colorvu acusense turret focus

    Keep in mind adjusting the focus for closer objects will affect the focus for distant objects. You may be able to find a better balance between the two by adjusting it.

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    It's there all the time - be it over 30C or below 10C. I could pull it apart and try to manually adjust the focus, but the luckily the side affected isn't within the area we're most concerned about monitoring. If it was on the RHS I would be looking into it further. Edit: I've had similar...

    DS-2CD2387G2-LU 4mm 8MP ColorVu out of focus, black pixels when zoomed in?

    Yes, as already mentioned anything closer than that range will go out of focus. Mine also has an issue with the far LHS of the frame being slightly soft in focus compared to the rest of the frame (at all distances.)

    You'll revert to black and white images though. That can make it harder to identify any intruder.

    DS-2CD2147G2-SU - you can't see anything at night despite colourvu

    That's a bit odd. As others have said, you do need some visible light for the ColorVu cameras to work. You mentioned it is inside- I've got a few different motion activated night lights inside my house. Something like that would supply enough light.

    DS-2CD2147G2-SU - you can't see anything at night despite colourvu

    You could turn the on onboard LED light on- that's what it's fitted for. Much like the IR lights on normal cameras.

    No audio from Hikvision IP Camera linked to Hikvision DS-7216HUHI-F2 (2016)

    Have a play around with them all to see which gives the best sound quality. There can be a very noticeable difference.

    No audio from Hikvision IP Camera linked to Hikvision DS-7216HUHI-F2 (2016)

    Have you got the Audio compression set to G.711u ? That appears to be the only standard the DVR supports. It will probably only be accessable via the camera's web set up menu, not via the DVR. https://us.hikvision.com/sites/default/files/data_sheet/510658_thdds72xxhuhifxnseries091316na.pdf

    Hikvision DS-7732NI-14/16p after firmware update cannot type user name in?

    If the NVR was bought from an Australian Hikvision retailer the NVR will be locked to only accept Australian firmware updates. Loading other firmware (from the Europe site etc) will lock you out. Contacting your selling retailer to get the unlock file is your easiest option. A side point is...

    Anybody try the new Hikvision ColorVu 8MP ?

    Scanning quickly- 10m more light range on the "3", 10bD better WDR on the "2"... probably lots of other stuff I missed.

    Hikvision DS-7616NI-SE/P NVR Replacement

    Same here. A lot of the Dahua NVR's seem to have incoming bandwidths greater than 10Mbps per channel and are readily available. I'm not sure how compatible they are/ how well they work with Hik cameras though?
