    A few basic questions about IR lights

    A few years ago when I bought some 4k Dahua cameras direct from China I also bought some IR lights. The housings were half-spherical, about 2 or 3 inches in diameter, some had a face full of small regular-sized LED's, others had 4 high-power led's with lens in front of them. Both types of...

    HDW4431C constantly trying to contact a china IP address

    I have a pair of IPC-HDW4431C-A bought directly from China in 2016 with english firmware. They have different lenses and their firmware might be slightly different. The one in question has firmware 2.420.0000.17.R, build : 2016-03-13. I've configured my router to allow the cameras to connect...

    Vstarcam G96 - anyone know anything about these?

    I picked up something today (yes, I bought 2 cameras today) called a Vstarcam G96 (also for $30 CAD). It has no ethernet port. It's kind cool - it has bidirectional audio (build-in speaker) and SD card slot. When it's powered up it acts like an open wifi access point. So I connect to it, and...

    Swann SW-Viewcam (need to change language from Chinese to English)

    I picked up something called a Swann SW-Viewcam today (for $30 CAD) from a local retailer that sells a lot of "refurbished" electronics. The camera is spec'd at 720P and it looks like the older D-Link DCS-9XX cameras. It has an SD-card slot (which is nice). I see that it is referred to by...

    HDW4631C-A or 4433 or 2MP Starlight - what to buy?

    As someone who owns a few english 4431 and has seen them record video's of trespassers in the middle of the night, I have mixed feelings about the desire for low-light performance (ie - the real value of B/W recordings of intruders / thieves). Color gives so much more info (makes faces more...

    4MP Starlight 2CD3346 - pic of main board, can I downgrade firmware?

    The camera in question is a 4 mp Starlight / EXIR DS-2CD3346DWD-I. It's a turret. I'm showing a photo of the main board inside the camera. This is obviously a China-only camera. I can find no listing on the Hikvision english website for this camera (out of curiousity - is this camera offered...

    Relationship between in-camera detection settings and NVR?

    First let me say that putzing with NVR's is new to me - specifically NVR's that are capable of communication with IP cameras that is. I recently played around for the first time with such an NVR (Hikvision DS-7208HUHI-K1) and managed to connect a couple of Dahau cameras to it using Onvif. One...

    IPcamtalk website and older versions of firefox

    I've experienced instances where I give my FF browser the URL for a camtalk thread and I get the circlling thing on the tab, with the word "connecting" and it stays like that until I close the tab. Or I'm at the top level of a sub-group and can see all the threads, I click on one and again I...

    How to work with Chinese language DS-2CD3346DWD?

    A friend of mine bought what looks like a Chinese-language DS-2CD3346DWD-I and I've been trying to log into the thing (which I thought I did but maybe not) and see if there's a way to change the language to English. I did a search here on IPcamtalk for 2CD3346 but nothing came up (no mention of...

    HDBW4433R-ZS - can't get live video ONVIF Device Manager

    I have an older Dahau 4431C-A which I can get working with Onvif device manager (and Hikvision NVR) but I can't get live video stream from a new 4433R-ZS. Onvif device manager can see the camera, show the Identification, Time Settings, Network settings, etc, it can show a thumbnail still...

    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?

    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?

    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...

    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...

    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...

    Difference between different Dahau NVR models?

    All these NVR's are similar (white plastic box): DH-NVR4108 / DH-NVR4104 NVR4108-P / NVR4104-P DH-NVR1104-P NVR1108-P Some are 4 channel (4 camera) and some are 8 (the last number in the model number). What I don't understand is, some have "DH" in the model name (and some don't)...
