    API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening

    Good idea @wittaj , but I should have been more clear above that I have looked at this a LOT ;-) The camera is running at 6FPS and I've trying varying the Compression, Encoding Strategy, CBR/VBR, etc. It's super simple to grab a PNG from the web interface ... and then I just compare to the same...

    Merry Christmas And Happy New Year!

    Welcome back @EMPIRETECANDY - LOL was that fireworks video taken with one of your camera's?!? ;-) Since you said you are "going back to work", can I "ping" 'ya with some software bugs that I think should be easy to fix? They are repeatable on both of my T54IR-ZE-S3's ... and I suspect exist...

    API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening

    On post #190 of this thread, @bigredfish posted some images showing the exact same problems with the "big brother" Z4. As mentioned, maybe it's because I'm a photographer, but the banding just jumps out at me as absolutely terrible from the API image. Yes, you would obviously expect some drop...

    Any tips on how to improve audio quality on the internal microphone of T54IR-ZE-S3?

    Thanks @duplo as that seems to work a little better - I'll try doing some more testing. BTW, I like the Noise Filter idea ... but it's either ON/OFF and (IMHO) overly aggressive. So maybe in a future release, they will provide a slider to adjust the amount applied.

    Any tips on how to improve audio quality on the internal microphone of T54IR-ZE-S3?

    Thanks for the feedback @wittaj .. any idea why the microphone is better on the bullets? BTW, since the Z4E is a "telephoto" camera, nice work by Dahua with whatever they did so the microphone similarly "reaches" out. FYI that on the T54IR-ZE-S3, it's a small "slot" on the bottom of the...

    Any tips on how to improve audio quality on the internal microphone of T54IR-ZE-S3?

    I recently picked up a couple of T54IR-ZE-S3 eyeball cameras that I've been pretty happy with. Nice bonus is that it has an internal microphone ... which is certainly easier than running a powered pigtail and audio plug to an external microphone that one has to "hang" somewhere. The audio is...

    WebSocketServer.exe?

    OK - add me to the list of people annoyed by this! ;-) So what exactly do you do to get rid of this message? It pops up with Edge, Chrome, and Firefox. I too had have webserver23450.exe in the recently created directory of C:\Program Files (x86)\webrec\Torch\5.0.412649.0 ... so I moved...

    Internet Explorer via W11

    FYI that here's another/easy way to run Internet Exploder - simply creating a desktop short-cut that has a Target of "C:\Program Files (x86)\Internet Explorer\iexplore.exe" ienotdead -embedding" Click on that, allow it to install the plug-in, click OK for all the security warnings (YIKES!)...

    Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps

    As always @wittaj, your suggestions are excellent. Reading through the threads ... and then doing my own research, it seems the easiest way to run Internet Exploder is by simply creating a desktop short-cut that has a Target of "C:\Program Files (x86)\Internet Explorer\iexplore.exe"...

    Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps

    Great point @TheOtherMike - I never thought to look at the data sheet since I assumed it would be 10/100/1000 ... since most stuff is these days. For example, I just looked up the specs on the 5 year old Hikvision 5526 that it supports 10/100/1000. When I did the test with SmartPSS, it took a...

    Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps

    Good suggestion ... but unfortunately I don't have switches that show that info. My "solution" is to hook my laptop up to the end of the cable run and run Speedtest. If it comes back at 100 Mbps, I know there is "something" limiting going on. But if I see 500+Mbps (I have GigE to the house)...

    Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps

    Ooops ... as a network guy, it's embarrassing that I made that typo ... and yes, MBps is (about) 10X Mbps. Thanks for pointing out @bp2008 and fixed in in OP. While it would not surprise me that there is a different code path (good point on buffer size), it's amazingly coincidental that the...

    Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps

    UPDATE: If you use Internet Explorer (with plug-in), you can download videos via the web interface at the full 100Mbps speed - note you can't go any faster because the NIC doesn't support GigE. Thanks @TheOtherMike for pointing that out on the data sheet (maybe for 2024, Dahua will go with...

    2MP vs 4MP vs 8MP

    AGREED!!! It would also be helpful if they would give us some idea of how "good" the sensor technology is ... or at least a date ... since a 2023 1/1.8" sensor should be able to outperform one from 5 years earlier. Obligatory comment that I would love Dahua to come out with a "light-sucker"...

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    What's doubly frustrating about the poor qualify of the JPEG from the API call is that the camera clearly has a sensor, lens, etc. to generate a pretty darn image ... so there is something goofy going on in the image processing software. Also see the examples I show in this thread. As a...

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Thanks @bigredfish for doing this. Maybe it's because I'm a photographer, but the banding just jumps out at me as absolutely terrible from the API image. Yes, you would obviously expect some drop in image quality, but seems like waayyy more than one would expect. I pulled the PNG into Photoshop...

    latest Version of DAHUA HTTP API FOR IPC Documentation ??

    Is there updated API documentation for the 5.0 software? I'm running 3.100.15OG000.0.R Build Date:2023-11-27 on a IPC-T54IR-ZE-S3 (with 2nd one showing up today - early Christmas present! ;-)

    Mini-Review - 5842-Z4E-S3 AKA B58IR-Z4E S3 - Replacement to the 5842-Z4E (8MP on the 1/1.8" sensor)

    GREAT examples showing the difference - well done! Ditto what you (and @EMPIRETECANDY ) said about how they are for different use cases. Gotta say I'm surprised to see that, because while the 8MP camera has smaller size pixels, the overall sensor size is the same (yes?) so assuming all those...

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Nope - just login to the web interface and grab a snapshot via that interface using the camera icon at the top right which (for me) is a multi-megabyte PNG. In another tab at about the same time, hit this URL - USERNAMEcolonPASSWORDampersandIP/cgi-bin/snapshot.cgi - which (for me) is a several...

    Ditto what @bigredfish and @wittaj said that I'm sure @eggy you'll be happy with the T54IR-ZE-S3 camera. I certainly am ... and in fact, just ordered a second camera ... plus have already switched to it at Watching Grass Grow ... ;-) LOL for cat lovers that here's a 12 second time-lapse from...

    Hikvisions newest Pro Series Hybrid cameras

    How would you compare the low-light performance of the Dahua 5442-ZE-S3 versus the 5526 and more recent 2/5/7xxxx cameras from Hikvision? Also, the Dahua "H" series has an F/1.2 lens versus F1/.8 ... so the light gathering is 2X ... but otherwise sensor quality, etc. is similar?

    Hikvisions newest Pro Series Hybrid cameras

    Can you please expand more on this @steve1225 ? I have a Hikvision 5526 from a couple of years ago and recently got a Dahua 5442-ZE-S3 ... the later appears to have noticeably better low light performance. Anyone making a vari-focal camera with F/1.0 lens and (good!) 1/1.2" sensor?!? ;-)

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Thanks for the response and it sounds like it's not specific to the "little brother" ZE ... which makes sense because this would not be a device specific function - i.e. might be part of the Web5.0 release - is that what it is called? There are some super-experienced Dahau users on this thread...

    Mini-Review - 5442-Z4E-S3 AKA B54IR-Z4E S3 - Replacement to the 5442-Z4E

    Any chance someone with the "big brother" Z4E can confirm the poor snapshot image quality that I'm seeing on the "little brother" ZE? Super simple - just take a snapshot using the web interface and then surf to USERNAMEcolonPASSWORDampersandIP/cgi-bin/snapshot.cgi The former should be a...

    Mini-Review - 5442-ZE-S3 AKA T54IR-ZE-S3 - Replacement to 5442-ZE

    Sorry I somehow fat-fingered the link above - click here to see how the image quality from grabbing an image from snapshot.cgi is MUCH less than if you do a do a Snapshot from the Live view using the camera icon. Any ideas on how to improve the quality?

    API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening

    While not as obvious in the daytime pictures, the same problem exists. 1st image is the 3,697KByte PNG as generated from the web interface. 2nd image is the 187KByte JPEG as generated from an API snapshot. 3rd image is a 170KByte JPEG generated from Photoshop using the the original PNG and...

    API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening

    Finally, here's a comparison of the "road area" of the Web versus API snapshot. This done by pulling the originals into Photoshop, cropping the same 1500x400 top right corner, and then combining into a single image. You can "see" the lightening plus the blockiness.

    API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening

    Here's a GIF (glad to see the forum allows it to cycle) that shows the Web snapshot versus the API snapshot. So yea, when I convert to GIF, the color space changes ... but if you look at the originals I posted above, you'll see the same "lightening" of the image. That's why I'm wondering if...
