    Dahua NVR to recommend

    > With modded you mean hacked? It's my vague understanding that the cameras I bought, indeed many of these 4k cameras that were being sold a few years ago (maybe still are) on ebay direct from china had model numbers that were "chinese market only" and as manufactured would have had...

    Better performance when DVR has direct camera (RJ45) ports?

    > You are incorrect. Also it's an NVR. Yea, I realized after I posted that these IP-camera recorders are usually called NVR's (N for Network?) even though the analog camera boxes (those are usually called DVR's - yes?) are also ethernet network-connectable (accessible). > The camera limit is...

    Better performance when DVR has direct camera (RJ45) ports?

    Correct me if I'm wrong, but with the Dahau 4-camera (and maybe also the 8-camera) DVR's only seem to have dedicated RJ45 ports for each camera if the DVR is a POE model. In other words, non-POE models have only a single network RJ45 port, which means they access all cameras over a single...

    What does "HS" give you? (4104 HS-4KS2 vs 4104-4KS2)

    What does the "HS" give you when looking at a 4104 HS-4KS2 vs 4104 4KS2? Is it just the size of the box? Nothing else? Also, what's the difference between, say, a 2104 HS-S2 and a 4104 HS-4KS2?

    Dahua NVR to recommend

    I have the same question regarding a recommended NVR for one or maybe at most two HDW4431C-A cameras I bought direct from China (ebay) a couple years ago. Doesn't have to be POE. The NVR just has to be able to work with these cameras (I think these came with modded firmware) and do basic...

    Carelessness cost me...I got hit...

    I'm still waiting for someone to make a commercial cell-phone IMEI catcher or sniffer that logs the presence and IMEI number of near-by cell phones. Take that to the cops when you get a break-in caught on camera and they'll be able to track down and prosecute the suspect. Because everyone...

    E-mail image frequency during motion detection 4431C-A

    I have a 4431C-A camera (bought from china with english firmware version date 2016/03/13) and I'm wondering how (or if) the camera can send more frequent emails during short-duration motion-detection events. There seems to be 2 primary settings for this - Anti-dither and Record-delay (if there...

    Why is HDW5231R-Z more than twice the price of HDBW4431R-ZS?

    The 4431's with 3.6mm lens is great for front-door security, even driveway security. Do you really need to ID people 50 yards from the camera? (The ultimate way to get an ID on people/thieves/vandals is to get the IMEI/MEID number from the cell phone that they're almost certain to be carrying...

    Why is HDW5231R-Z more than twice the price of HDBW4431R-ZS?

    > its motorized zoom and auto or manual focus. So the varifocal cameras have 2 motors? One for zoom, the other for focus? I haven't seen a need to adjust the focus on the fixed-focal-length 4431's I have (not that there's a way to actually adjust the focus on them that I can see).

    Why is HDW5231R-Z more than twice the price of HDBW4431R-ZS?

    I see one US vendor selling the HDBW5421E-Z (4MP) for $394 CAD and one Hong Kong vendor selling it for $320. That's nuts. I've bought a few HDW4431C-A (4MP) for around $100 (CAD) each and the images look great to me. Maybe the Sony sensor is better, but one or two extra IR lights aught to boost...

    Why is HDW5231R-Z more than twice the price of HDBW4431R-ZS?

    I see that the ebay price (in CAD) for the HDBW4431R-ZS (4 MP) is about $120, while the HDW5231R-Z (2 MP) is $270. Why would a 2 MP camera be more expensive than a 4 MP? Both are motorized varifocal, the 4431 has SD slot (I don't think the 5231 does). The 4431 is dome (this is a drawback, I...

    Anyone catch traffic from this?

    No need to go through the hassle of VPN. Just use port-forwarding on your router and set the camera to use some other port other than 80. I watch bots try to hit my residential IP address and beyond a few standard ports (like 80 or 8080) they rarely try anything else. I've operated many cheap...

    Trying to understand 44xx camera model-number format

    Your chart does not explain: - the difference between 4431 and 4436 cameras - how a turrent-style camera is denoted. According to your chart, the IPC-HDBW4431C-A is a "dome" type camera because of the "DB" in the model number. I think that "dome" means having a clear plastic cup covering the...

    Trying to understand 44xx camera model-number format

    I'm trying to figure out how to decode the model numbers on the 44xx line of Dahau cameras, and if certain combination of model sequences actually exist. So for starters, the model will begin with either (a) or (b) where (a) DH-IPC-HDBW (b) DH-IPC-HDW (c) DH-IPC-HFW So right off the...

    Dahua Firmware Mod Kit + Modded Dahua Firmware

    I soldered a micro-SD socket to the board inside one of my HDW4431C-A cameras and installed a 32 gb card. Once the camera powered up, I browsed through the setup options, including STORAGE, but found nothing new. In other words, the camera is not seeing or recognizing the SD card. So, if at...

    HDW4431C-A : Doorway Camera?

    Of the three 4431C-A cameras that I ordered and received last week, they came with firmware dated march 13/2016 and July 24/2016. The july firmware has the "smart encode" option (yes/no), the march firmware does not. I believe I'm seeing substantially lower bitrate (1/3 to 1/4) with smart...

    HDW4431C-A : Doorway Camera?

    I may be wrong about this, but can the HDW4431C be found on Dahua's website? Is the HDW4431C supposed to be made/sold to the China market only? I only see it being sold on ebay from vendors in China and Hong Kong (not that I've got a problem with that, I've just bought 3 of them and they were...

    Dahua Firmware Mod Kit + Modded Dahua Firmware

    Is there any way you can mod the email SMTP part of the firmware so it will work properly? I'm finding that SMTP authentication can't be turned off on the HDW4431C. My SMTP server is set up for no authentication, no ssl or tls, and I can't get this camera to work properly with my mail server.

    Can lenses for EcoSavvy cameras be bought from somewhere?

    Seems that when you order these Dahua 4 mp cameras that you have to specify a particular lens. I'm wondering why Dahua doesn't even show these lenses as accessories similar to the various camera mounts. These lenses can't be too expensive - maybe $10 each? Why doesn't someone sell a 3 lens...

    Any hardware that can detect nearby cell-phone as part of security setup?

    My idea of a perfect security setup for home (outside, driveway, etc) is to have a receiver that can detect a cellphone that comes into range (because even teen-age theives carry around their phones all the time). Ideally, the receiver could pick up on the IEMI number broadcast periodically by...

    Dealer for Dahua IPC-HDBW4300E-AS

    Can someone explain why any hi-res IP-camera includes NTSC or Pal in the specs? Because if the camera is not generating base-band analog video signals (output via s-video or RCA phono plug) then I don't see where, how or why the ntsc or pal video standard applies to IP cameras like the 4300.
