    How To Upgrade Amcrest / Lorex to Dahua Firmware And Get All Dahua Features

    Nope. Those direction are for HikVision firmware and cameras. see Dahua IPC EASY unbricking / recovery over TFTP ( I find the simplest way is to add the required IP's to my Windows box in the 'advanced' section of the Ipv4 configuration)

    How To Upgrade Amcrest / Lorex to Dahua Firmware And Get All Dahua Features

    your camera is an SA (per the updateSerial=IPC-HFW3841EP-SA you posted). just because the -AS exists as a Dahua doesn't mean it's the same... (then again, they may well be close enuf that the same FW's work) I would try the firmware with the right HWID in it (as i linked to) that most closely...

    How To Upgrade Amcrest / Lorex to Dahua Firmware And Get All Dahua Features

    actually, the HWID you want to match is IPC-HFW3841EP-SA . Look for DH_IPC-HX3XXX-Dalton_MultiLang_NP_Stream3_V2.800.0000000.7.R.201118, which has that exact HWID in it's check file... I previosuly posted it here: Smartening up the Lorex LNB8005C 8MP mini bullet. there's also a newer 14.R...

    Review of the Hikvision OEM model IPC-T2347G-LU 'ColorVu' IP CCTV camera.

    no, it must be set to timing (auto disables the 'triggered by event' option. BUT, you must also 'link' the event to the 'Flashing Alarm' in the event/Linkage Method page(s)...

    Review of the Hikvision OEM model IPC-T2347G-LU 'ColorVu' IP CCTV camera.

    although, I just re-loaded the 5.6.2 with 'triggered by event' option and am not seeing the same behavior. (ie, it seem to work fine w/o resetting anything) I only see 'triggered by event' option if 'LED On' is set to 'timing' (nopt 'auto'), and only see the threshold setting if 'triggered by...

    Review of the Hikvision OEM model IPC-T2347G-LU 'ColorVu' IP CCTV camera.

    'restore' from the GUI will usually do the trick. 'default' (same as holding reset button down on reboot) would require reconfiguring networking and admin password, more of pain and last resort...

    How To Upgrade Amcrest / Lorex to Dahua Firmware And Get All Dahua Features

    upgarding to the newere amcrest FW may have updated your bootloader, which may prevent (or at least make it harder) taking non-Amcrest fw going forward. So you may be SOL.. my most reliable way to get DH firmware on these is to put the oldest possible Dahua fw that supports the hardware first...

    Hikvision how to set up another computer on the same network to see the cameras?

    Initial review of the DS-2CD2347G2-L(U) ColorVu 2.0 IP camera.

    good, info. I'm sure that will save others some head-scratching. Depending on your NVR solution, you may be able to rotate the image there, for example BI can do that (but of course, one must disable camera overlays or live with them sideways)

    Figuring out Dahua OEM model of Lorex

    I believe the P in the model number is some sort of feature identifier (like not having an SD card or soemsuch), but i'm pretty sure it's not NTSC/PAL. yes. N/P is used in the firmware filenames for NTSC/PAL, but not in the mdoel numbers. In any case, this firmware has IPC-HFW4830EP-S in the...

    Smartening up the Lorex LNB8005C 8MP mini bullet.

    yes, the run commands are aliases defined in the current bootloader environment and it's important to make sure the new FW has the same .img files as defined in the env, tho Not all of them need to be replaced (particularly the boot loader itself) tho. and as for Lorex FW, we already have...

    Smartening up the Lorex LNB8005C 8MP mini bullet.

    use a small flat screwdriver or spudger to pick up and peel off the front cover and reveal 4 philips screws. the adhesive is decent enuf that you can re-apply later.

    Best night cam special use case - No illum/No Ident

    FWIW, Hikvision's default 'auto' exposure mode has always been a limit setting. IE, setting it to 1/60 means the longest exposure will be 1/60s.... ( I doubt Anke would disable that - make it truly fixed - for market differntiation)

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

    did you get the 2.8 or 4mm version? "Lens Distortion Correction" is really only useful on the 2.8's that have significant distortion/stretching around the edges, and it works (mostly) by cropping the image somewhat. So you might as well just get the right lens in the first place...

    Lorex LNB8005B-C and Dahua firmware (Solved with instructions)

    see also: Smartening up the Lorex LNB8005C 8MP mini bullet. dahuawiki seems to have US model numbers, that are not the same as the international model numbers, which may explan not finding the ipc-hfw4830EP-S the Lorex LNB 8005c/8111c maps to.

    Lorex LNB8005B-C and Dahua firmware (Solved with instructions)

    I've only been able to get the Dahua firmware onto the LNB8005c (and lnb8111c) using the TFTP update mechanism. see Dahua IPC EASY unbricking / recovery over TFTP but if you've got the ONVIF compatibility you need with the later Lorex FW, maybe you don't need the DH FW? in any case, the DH...

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

    I'd have to agree this is my new 'hero' cam. My only regert is having bought (2) of the 4mm instead of (3) 6mm to cover the 180 degree 'overview' on the street side of our house. 50% more pixels per foot with that sort of low-light chops goes a good ways to making people more identifiable...

    gama/brightness problems

    I see you list two cameras in your sig and have at least 3 in your BI setup. that doesn't tell me which one you're talking about, or even if it's any of them in your sig, which could be out of date or incomplete. i suppose i could guess or ASSume, but we try not to do that around here. just...

    Coating on lens

    ah, that makes some sense. condensation inside the lens assembly itself. should work itself out eventually, assuming the cam's moisture-sucking silca pods still have some life in 'em... these can also be 'refreshed' by baking in a very low oven (170F or less) for an hour or two to drive off...
