    B5422E-Z4E / HFW5422E-Z4E specification

    Mmm - I guess there are several possibilities. I wondered if the difference refers to Dahua now specifying the minimum illumination (in colour and maybe 1/3s shutter) when at full optical zoom which I imagine is worse than when zoomed fully out. It would be helpful if Dahua is able to clarify...

    Review: OEM IPC-B5442T-ASE-NI 4MP Pro AI Full-color Fixed-focal Bullet

    Hello bigredfish Thanks for this post. I was just at the point of ordering two of these from Andy (one bullet and one dome) but hadn’t realised that it would appear “full colour” cameras have a permanent IR block. I live in the country without street lighting and at the moment use lots of...

    B5422E-Z4E / HFW5422E-Z4E specification

    Needing a 4MP camera with a long lens and the best possible low illuminance performance, I bought a B5422E-Z4E from Andy. It's an excellent camera. I am confused by the minimum illuminance specification - Andy's web site states 0.0006 lux. I now see that Dahua has published two...

    Blue Iris does not find my new B5442E-Z4E

    Bingo! This works. What fantastic support from across the pond! Very many thanks. I wonder if I will find another problem without ONVIF?

    Add what in front of channel? (ps. copy and paste plus changing subtype works fine for all my other cameras)

    Blue Iris does not find my new B5442E-Z4E

    I get video with the generic screen too but BI doesn't read the substream etc PS I'm not clever enough to know why I get the full image and a thumbnail

    Blue Iris does not find my new B5442E-Z4E

    I did update the password (to the same one in the ONVIF account. Before climbing the ladder, I’ll try a different password.

    Blue Iris does not find my new B5442E-Z4E

    Thanks again for your support samplenhold. Unfortunately, the ONVIF password had been updated automatically. When I blank the address in BI and do a camera discovery, this one is not in the list - doesn’t need any password. ONVIF definitely still not working. Unless you have any other ideas...

    should i install a new poe cam

    Thanks for the quick reply samplenhold! I have the same firmware version as you. With Edge, my CPU load is 70-75% with 15fps, i frame 30 and max bitrate (6144kbps). I am not an IT expert but for Blue Iris, it now looks like my ONVIF is not working. However, the camera says ‘on’ in...

    should i install a new poe cam

    Hello samplenhold My new B5422E-Z4E is not found correctly in Blue Iris. What about yours? I created a post in Blue Iris/troubleshooting but so far no feedback. Another comment is that when using a browser, the camera automatically switches to the substream after a short time I think due to...

    Blue Iris does not find my new B5442E-Z4E

    Having entered the correct IP address for my new B5442E-Z4E from Andy (Dahua HFW5442E-Z4E), although I can get video using Dahua RTSP, BI does not recognise this camera (suggests foscam) and so, for example, does not correctly read the sub stream (unlike all my other Dahuas). Nor is it in the...

    Benefit of a dome cameras instead of a turrets or bullets

    Hi mech, thanks for your message. If I interpreted your video correctly, it looks like the IR200 has a very narrow spot beam and yet according to the spec it’s much broader. I want the illuminator to reach from the house down the drive to the road which is a distance of around 100ft. I think...

    Benefit of a dome cameras instead of a turrets or bullets

    Many thanks for your feedback fenderman, you have now made me think a bit harder. I don’t use the built-in IR but it’s true to say that my two turrets also don’t normally suffer with cobwebs. It could be the problem especially with two of my four HFW8231E-Z bullets is their location on the...

    Benefit of a dome cameras instead of a turrets or bullets

    After several years, I am going to add a couple more cameras to my system at home (currently a mixture of 11 x Dahuas) and am researching my preferred choice. Most forum members appear to favour turrets. However, my bullets and turrets are plagued by cobwebs, even soon after climbing the...

    BlueIris isn't recording smoothly

    You know what senrab, mine’s now intermittently started to do the same thing. I’m a sucker for installing the latest updates even though I haven’t as yet started to use the new features apart from viewing the sense and trigger rectangles on the console. Did you try installing an earlier...

    Pandemic threat? Anyone else concerned?

    Hello Q (Herman Munster). In general, I read your comments with interest. However, don’t you think that in this thread, the time has come for you to rise above it all? I’m sure that we all still want to hear the result of Lily’s test (your wife), but being a vampire with a fiery temper I’m...

    Common issues with camera image

    Hello wopi, many thanks for your reply. As you have explained, it’s important for me to discover that (unfortunately) the scale is logarithmic when making comparisons. It’s also interesting to know that sensor performance has further improved. However, being a pensioner, unless my cameras die...

    Common issues with camera image

    To add a little information about my very basic sensor comparison test, I think I recall reducing the shutter time by around 3x to get a broadly similar image brightness on the starlight camera (not 10x if it’s merely a simple linear relationship). However, without noise reduction, the image...

    Common issues with camera image

    Hi wopi, I have 11 cameras around my home, all Dahua and are as follows:- 1 x SD3282D-GN (initial Dahua purchase in late 2013) 1 x HDW4221EM (focus not brilliant but the lens assembly is glued together in this model) 1 x SD22204T-GN 1 x SD29204T-GN 1 x HDW4300C starlights:- 4 x HFW8231E-Z...

    Common issues with camera image

    As reported by others wopi, many thanks for your very informative post. Having both starlight and non starlight 2MP Dahua cameras, I have a related query regarding sensor performance. The sensor sizes and other parameters appear to be similar and so I ask, is the huge 10x difference in the...

    SD22204T-GN Firmware Update Issue

    I too have an old hardware version of a branded SD22204T-GN that I updated using firmware dated 2016-05-17 (see below) but doesn't quite work properly. The camera itself is happy when changing the password but Blue Iris will only find the camera model etc when its password is "admin" and on...

    Review-I'll be the guinea pig for the new SD59225U-HNI PTZ.

    Hello CastleSurveillance, in the video start caption I am approx 28 feet away from the camera, the french window door is at 33 feet and the small dog fence through which I enter is at 42 feet.

    Review-I'll be the guinea pig for the new SD59225U-HNI PTZ.

    Just seen these recent damning posts for the 59225 auto tracking and couldn't resist chipping in with a few positives. 1. If you want to "see who did it and not just what happened", zooming in is probably necessary, especially when trying to identify someone who you don't know. 2. Tracking a...

    SD29204T-GN latest Firmware ?

    Thanks for the helpful suggestion looney2ns. The camera is now working in Pale Moon with newer firmware and finds its sd card. I set it back to factory default first. That may have helped but I'm pretty sure that what cliched it was using a different file download from dahuasecurity's...

    How to capture clear frames of fast moving objects?

    Thanks for the response ipOsX. I guess I wasn't very clear, I currently use 200GB for each of 10 cameras, 2TB in total. Attached is a setting example for one of my cameras. I generally record direct to disc with Blue Iris unless I'm trying to pick out spurious alerts with overlay rectangles...
