    Dahua NVR - DAHUA DH-NVR 4108

    It would be great to learn that the feature is not really missing, just moved or not obvious.

    Dahua NVR - DAHUA DH-NVR 4108

    "There is no official info about removal of the snapshot button (while in playback) from the menu." I agree, nothing like that is mentioned in the release notes. "You may try priviuos versions of it's firmware." I can't go back to any previous versions; these updates contain several important...

    Dahua NVR - DAHUA DH-NVR 4108

    This is 3.215.0000000.3 2017-11-06. When I bought the NVR it had release .1 and the Snap icon was next to the Mark icon but was inactive. With release .2 the icon disappeared.

    Dahua NVR - DAHUA DH-NVR 4108

    While in Playback, I go to FullScreen. The old Snapshot icon does not appear. If I click on the Start icon, the Save icon remains inactive unless I select a Stop time. No way to save one frame.

    Dahua NVR - DAHUA DH-NVR 4108

    I have the NVR4108-4KS2. The current firmware does not have manual snapshot in Playback. The feature was broken in the previous release, now it's been completely removed. I think this is a serious flaw in an otherwise decent product. It forces me to create a video clip, transfer it to a USB...

    How's This NVR Thing Work?

    I can address the NVR question: - "mini 1U" means that the chassis can only house a single 2.5" HDD. - Is there an HDD installed? - The NVR is locally controlled only by the mouse. Any settings choice that requires entering text (e.g. the password) will pop up a tiny virtual keyboard. -...

    Dahua NVR5416-4KS2 Fans

    "I think it is mostly wind noise. Might try cutting the grates over the fans." My NVR4108 (non-POE) had a high-pitch whine that was not okay given its location. This noise disappeared completely when the case cover was removed, indicating that the sound came from air passing through the vents...

    building my own POE switch

    I was advised that these cheap ($5) V/A meters might not last very long running 24x7 so there's a micro-toggle switch just to the left of the display. I just turn it on from time to time for a health check. The 12.5 volts is steady as a rock. The 1.29 amps shown was four cameras in the...

    building my own POE switch

    All four of those devices are nicely simple but all provide 48v. My first collection of $20 cameras only supported 12v. Today all my cameras are POE-capable but none have PTZ so I'm not missing out on anything. The one camera that matters most is on a 45 meter outdoor CAT5e run and runs sweet...

    building my own POE switch

    A typical 8-port POE switch with a 48v brick costs about US$85 on Ali. I believe I spent a very similar amount on this build. One driving factor to do it myself was that my first cameras were cheapie 1080p models that did not support true POE. That wasn't important to me, as all my...

    building my own POE switch

    Two years ago I put together my first CCTV and I didn't know much at all, but I was sure I didn't want an NVR with POE ports, so I built my own 12 volt insertion panel. I used parts sourced locally and through AliExpress. I can't really say why I didn't just purchase a POE switch; probably I...

    NVR 4208 replacement fan for side unit

    Followup from my post above: I got the 12vdc 40mm maglev fan from AliExpress. It turned out to be noisier than the Sunon supplied by Dahua. I also concluded that the whine I was hearing was mostly coming from the air flow through the louvers in the NVR case. So, I will calculate a resistor...

    Dahua NVR with POE, non Dahua camera's

    If an ONVIF camera doesn't immediately work on a Dahua NVR, it might be useful to run ONVIF Device Manager ver. 2.2.250 to see if the camera has any unexpected settings, like password, resolution, etc.).

    NVR 4208 replacement fan for side unit

    I just ordered a replacement fan for my noisy NVR4108. It's twice as thick (40x40x20) but I'm not expecting that to be a problem. NANILUO Free Shipping Wholesale Maglev fan KDE1204PKV2 4cm 40mm 4020 12V 0.6W silent quiet server inverter cooling fan-in Fans & Cooling from Computer & Office on...

    seeking upgrade for an odd camera

    I bought a 5MP camera thru AliExpress in 2015. It's not a great camera but it gives a usable image in 3MP and I like the 2.8 lens. Yesterday I upgraded my Dahua NVR firmware and this cam no longer provides video. The NVR finds it in Search but cannot determine what to do with it. Manual Add...

    Dahua NVR4108 - manual snapshot question

    I can now answer my own question. The NVR4108HS-4KS2 came with 3.210 firmware from May 2017. This feature did not work. Now I have installed 3.215.0000000.1.R.170902, and the Manual Snapshot icons have been removed from the Playback screen. So, the feature was broken and Dahua has chosen, at...

    Dahua NVR4108 live preview

    "Have you tried a higher resolution?" The only higher res choice is 4K. I connected that to my UHD Samsung and confirmed that the TV switched up to that mode. No impact on this 3MP jerkiness in Live Preview.

    Dahua NVR4108 live preview

    Thank you TonyR for your suggestion. I knew that my NVR came with 3.210 firmware from May 2017 but had not checked if there was anything later, and yes there is. The latest firmware for the NVR4108HS-4KS2 is 3.215.0000000.1.R.170902, much more recent. I'll be happy to install that, no matter...

    Well, I thought it was an insightful suggestion but no, switching to 4K output didn't fix the issue. I hate mysteries.

    Dahua NVR4108 live preview

    Thank you for the reply mat200. Yes, this model is capable of 4K output, so that is a real possibility. I'll drag my 4K TV in from the bedroom, see how that works, and post the results. Cheers.

    Dahua NVR4108 live preview

    I just bought this NVR and have connected 2 generic 1080 cameras, 1 generic 3MP camera, and 2 Dahua 3MP cameras. The playback on all cams is very smooth but the live preview on all the 3MP cams is jerky. I only see this via the NVR's direct monitor. If I look at the live view via PSS it's...

    Dahua NVR4108 - manual snapshot question

    I just upgraded to this NVR. It seems pretty likeable in most ways but I can't get it to take a manual snapshot during Playback. I follow these steps: 1. Main Menu->Search 2. Plug in flash drive to USB port 3. Select the day 4. Select 1 Ch. view 5. Select Ch. number 6. Select Play icon 7...

    Dahua NVR2108HS-S2 question

    My old NVR can play back up to 16x speed. Can this Dahua Lite NVR do the same? Or is it limited to 8x ?
