    Dahua NVR > what does this mean? "Switch Operating Disk: /dev/sda(0)-->/dev/sda(1) reason(0)"

    Not that I installed (on the NVR). I'll have to physically check if someone plugged one in while I was gone.

    Dahua NVR > what does this mean? "Switch Operating Disk: /dev/sda(0)-->/dev/sda(1) reason(0)"

    I only have 1 HD. (I checked if someone installed another drive while I was gone. SmartPSS > Storage > Disk Manager > only 1 disk is listed (and it has the old recordings).) So any other ideas what this means?

    [restart fixed, but unknown cause] Crippleware [or bug] by Dahua? Motion Recording was disabled for all non-Dahua IP cams on Feb 27, 2024

    Clarification. I used SmartPSS > logs; I didnt check logs on the actual NVR interface. Is that what you mean (that the NVR version isnt helpful)? Ty.

    Dahua NVR > what does this mean? "Switch Operating Disk: /dev/sda(0)-->/dev/sda(1) reason(0)"

    I checked my NVR logs for suspicious activity. Someone is tampering while I left the house. What does this mean? And how/where do I go to undo it. Ty. "Disk" category Switch Operating Disk: /dev/sda(0)-->/dev/sda(1) reason(0)

    [restart fixed, but unknown cause] Crippleware [or bug] by Dahua? Motion Recording was disabled for all non-Dahua IP cams on Feb 27, 2024

    So any suggestions on which Category to re-check in the logs? I want to rule out bug, user error, or hacking. Ty.

    [restart fixed, but unknown cause] Crippleware [or bug] by Dahua? Motion Recording was disabled for all non-Dahua IP cams on Feb 27, 2024

    Thanks for your post. So you did update the NVR, and then non-Dahua IP cams would not work (with motion detection)? Or did the non-Dahua IP cams ever work (with motion detection)? If you want, post your Manufacture list (Cam > Channel list for IP cams). But blur out the exact ports and serials...

    [restart fixed, but unknown cause] Crippleware [or bug] by Dahua? Motion Recording was disabled for all non-Dahua IP cams on Feb 27, 2024

    Thanks for telling us this. And to clarify, I dont think I or anyone made changes to the IP cameras using any NVR interface. (I checked the logs and didn't find anything except the S.M.A.R.T. entry, whatever that means?) But if someone can tell me anything else to check for in the logs (which...

    Hi guys, thanks for the replies and checking on me. UPDATE 1 - fixed Summary UPDATE 1: Restarting the NVR FIXED it - now the IP cams show yellow Motion bars using SmartPSS.

    [restart fixed, but unknown cause] Crippleware [or bug] by Dahua? Motion Recording was disabled for all non-Dahua IP cams on Feb 27, 2024

    1. Did Dahua push a stealth "crippleware" update? 2. How can I re-enable Motion Recording (yellow bar playback) on my IP cameras? 3. After #2, please explain how to setup IVS on my IP cameras? Thank you. On Feb 27, 2024, after 7:30AM – the Motion Recording (the yellow bar) was disabled on all...

    What causes Analog camera delay and ghosting?

    Thanks for the summary. Can you remind me where to go to enable AI Human detection per camera? SmartPSS or Web interface and which Topic/tab? (I forgot where, but I want to show you a pic - that it wont let me select the IP channels to set.) Yes. I manage view 2 devices and get my recordings...

    What causes Analog camera delay and ghosting?

    The pic didnt post. Can you fix it? (Im not exactly sure where to click on SMartPSS to get to the AI settings. Do you have a vid that shows how to set this up from within SmartPSS? Years ago I searched, but what their video showed, wasnt displayed as a setting for me.) 1-8 are Analog channels...

    What causes Analog camera delay and ghosting?

    Thanks for the link, and it's on Amazon (easier to shop/ship). So do his own brands work for the AI on the Dahua XVRs? Or only the specific Dahua cameras that he sells? (but they have to say Dahua?) I see "EmpireTech 4MP Smart IR Fixed-Focal Lens Mini Bullet IP Camera,Support SMD 3.0 and IVS...

    What causes Analog camera delay and ghosting?

    Yes, Im seeing that now. But the seller/listing did not tell me that (years ago when I was shopping for XVRs). And I talked to Dahua support recently. They said that I have to use Dahua cameras to use AI detection for IP cams. But again, they didnt disclose that. (It sounds like theyre using...

    What causes Analog camera delay and ghosting?

    Thanks for that extra info. The Analog brand is unknown or "Quadbrid." (I ordered a Varifocal Dome, and they sent me this Turret camera - listing now updated. So Im testing it, learning what it actually is.) https://www.amazon.com/dp/B0BNM4W717 And my IP cameras are a mix, but not Dahua or...

    What causes Analog camera delay and ghosting?

    Wow, thanks for that link. (It has been difficult to find comparison information.) I have the Penta-Brid XVR5116H-X: "16+8 Channel 5MP Mini 1U Digital Video Recorder Support 16CH HD-CVI/HD-TVI/AHD/Analog up to 5MP, 8CH Additional IP up 6MP" So does this model support full 5MP for analog? (I...

    What causes Analog camera delay and ghosting?

    I have a Dahua XVR hybrid that uses IP and Analog cameras. Question 1) What might be causing my Analog camera delay? I had a low detail Analog camera setup (900 lines or something). Then I re-used the BNC cable to connect a new 5MP Analog camera (which has settings for HD CVI, Analog, AHD, and...

    Where to local buy PTZ Ceiling Mount Bracket?

    Thanks everyone for naming hints. I was trying to think of what they would be called at Home Depot. Update: I did have clearance to install this with the L bracket. But wow, this camera rotates so fast when going from Preset point 1 to 2. Plus it has 30x zoom. So with the weight balanced on the...

    Where to local buy PTZ Ceiling Mount Bracket?

    Thanks. Wasnt sure if we can post AZ links. Yours costs a lot, so would this one not be the correct weight rating? My camera weights about 5.2lbs. https://www.amazon.com/BeElion-Aluminum-Mounting-Hikvision-Surveillance/dp/B09T2XY2MR/

    Where to local buy PTZ Ceiling Mount Bracket?

    This alternate style. Outer diameter of the socket (camera Male that goes into the Female mount) is about 45mm. And on Amazon, I saw the Female diamater is 49mm, so I'm guessing that is the standard I am looking for. Ideas of local store names I can search? (Fry's Electronics shut down.) Thanks...

    Where to local buy PTZ Ceiling Mount Bracket?

    Hi, can anyone give me names of Local stores that sell PTZ Ceiling mounts (Im in SoCal), that I can buy in person today? Thank you. I just got a shipment, discovered I'll need a Ceiling mount instead of L. But Amazon wouldn't ship for 3 days, and I don't know the names of local stores that...

    How to calculate zoom from Lens range?

    Thanks so much for the pictures! I appreciate that. A related question. I see a lot of the high end PTZ cameras have only 4MP. (My NVR is 6MP max, but I aim for 5MP since it is faster to display.) So do the high end cameras (sold by IPcamtalk) have better lens that their 4MP has as much detail...

    How to calculate zoom from Lens range?

    Hi can someone please tell or direct me: how can I confirm the zoom range based on lens range? E.g. if it says lens = "4.5- 148mm" I thought the calculation is 148 / 4.5 = 32.8X Optical zoom, But I thought these cameras only come in 30x then 36x formats. Thus when someone says their camera is...

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    Thats what wasted weeks of my time. I did read the stats for many listings, then had to specifically ask each seller and tell them that others were selling fake cameras, so tell me the real lens range. And most were fake. So then I had to ask the next seller. Then I found the camera in OP and it...

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    I saw a post here where someone used different firmware model in their cameras, and it worked. Thats why I asked here. Im hoping someone has 30x firmware for a China PTZ, that may be compatible with mine. I also read that some China sellers are hacking their firmware (before sales) to give fake...

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    This cam has a physical reset button near the POE connector. Would that reset the Firmware to their original one? or just the settings? And Im willing to risk the Firmware since if it fails I can still return. Not my fault their factory firmware doesnt work. And what did you pay for how much...

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    Ah, I see. Thanks. I did look at their list. Way too expensive for only a 25x optical - costs $700 more than my 20x optical (which works good). Im in the market for a 36x optical for $255 from the 20x seller that I trust. But his cams arent available in time. (He sells from China and on Amazon -...

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    Thanks for the reply. Technically I have the Firmware for my 20x PTZ. But Im seeking more information if it's safe/possible to use Firmware for a 20x on a 30x. Or if someone has a better match. And Im not a business, I cant afford your cameras. So that's not an option.

    Please help with Firmware for 30x PTZ camera (that has buggy firmware) - for Duhua NVR

    Hi, can someone please 1) Give me firmware for a 30x PTZ camera (it is 8MP, but I only need 5mp). It has white and IR LEDS. (But I want the Whites disabled.) It has human AI detection. 360 rotation, POE connection, and no WIFI. Let me know if there's anything else I need to tell you about...
