IR sensitivity differences between 5442-S3 and T54PRO-ZE ... puzzling results
In some of the discussions about trying to get good night-time motion capture with the 54PRO's, I commented that "Is it possible that the "3D NR" on the 54PRO that (as you can imagine with something that "averages" over multiple frames) just does dismally with moving objects in low light?" and... -

T54PRO-ZE Field-of-View (and change in aperture/exposure) as focal length changes
A while back, I read this post from @Perimeter ... so I setup a T54PRO-ZE 10' away from my garage along with some various "measurement props" and then took a dozen snapshots as I zoomed from 0 to the maximum of 2426 - recording the zoom/focus numbers. I then pulled those images into Photoshop... -

T54PRO-ZE wiring harness - lots of wires - believe 12V power OUT is new (and probably on other 2025 cams)
FYI FWIW that here's a picture of the wiring hardness from the T54PRO-ZE ... figured a searchable post might be handy for those down the road wondering who, like me, are not long-time expert installers like many here. I believe the other new cams have similar wiring ... and that the 12V power... -

T54PRO-ZE versus ... another ... T54PRO-ZE ... ;-)
Why would there be anything interesting about comparing a T54PRO-ZE versus ... another ... T54PRO-ZE?!? Well ... it might provide some insights into unit variance ... albeit it's only two cameras. Plus when I had 'em mounted several feet apart (vertically), I thought I was some softness in the... -

Less sharpness in T54PRO-ZE (versus 5442-S3) possibly due to noise reduction being applied even if set to ZERO?
[Spinning up a separate thread from the "main one" if anyone want to comment SPECIFICALLY about this topic] So I have the been comparing the T54PRO-ZE (running the 0731 firmware) and the 5442-S3 for several days now ... and one things that keep "bugging" me is the T54PRO-ZE pictures just don't... -

T54PRO-ZE versus T5442-S3 in low light
[I figured this specific topic was worth spinning off from the main comparison thread] UPDATE: The first set of pictures were taken with the 0928 Firmware ... but the Gain controls were changed from what we are used too. Per @EMPIRETECANDY, consider rolling back to 0731 Firmware. I just got... -

Boat Detection is a recent new feature per the "Network Camera Web 5.0 Operations Manual"
LOL that I was looking at the manuals associated with the T54-PRO-ZE at this link ... and there's a recent new feature of Boat Detection! ;-) Per the top of the document Revision History - V1.2.5 - Added Boat Detection - August/2025 And there are several pages starting at page 113 that is... -

Minor Bug: Encode->Overlay->Channel Title is NOT enabled, but text shows up on snapshots (not on video as it should)
I've got a IPC-T54IR-ZE-S3 running the very latest software ... although I believe it may have been in the previous version as I looked at snapshots from before the recent upgrade. Encode->Overlay->Channel Title is NOT enabled ... but the default value of "IPC" was still there for Input Text... -

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... -

Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps
2025_10_18 UPDATE: This problem still exists with the new T54PRO-ZE ... using both @EMPIRETECANDY and Dahua firmware. It's very easy to demonstrate. Login to the camera web interface with any of Chrome, Edge, Firefox in Windoze. First, pretty much everything works ... WITHOUT the plug-in ... -

API Snapshot quality is MUCH worse than Web Snapshots - blocky artifacts in shadows plus overall lightening
TL;DR - Why are the jpeg's obtained via the API Snapshot MUCH worse quality than the png's from using the web interface? 2024_01_09 Update: Per @duplo post #18, you can change some "SnapFormat" settings which will improve the quality. I still feel that if you compare the JPEGs as generated from... -

Anybody tested the first vari-focal Hikvision ColorVu's: DS-2CD2747G2-LZS (Dome) and DS-2CD2647G2-LZS (Bullet)
I saw that Hikvision has added their first vari-focal ColorVu cameras - DS-2CD2747G2-LZS (dome) and DS-2CD2647G2-LZS (Bullet) - curious if anyone has tested them yet? These are F/1.0 lens and 1/1.8" sensor with 2,688x1,520 resolution ... so should be pretty decent in low light. But I think... -

Hilarious License Plate Capture - "DOGPOOP"
The Hikvision LPR software will sometimes do "duplicates" - i.e. the same vehicle will get multiple (slightly different) hits, especially if there is lots of writing on it. The first image shows it correctly got 474ZMA (82.4% validity) for this truck ... but then it picked up some lettering and... -

Hikvision LPR "Plate Mode" - pros/cons of Large/Small
Just an FYI for the Hikvision experts in this forum that I posted a question about the "Plate Mode" settings in the LPR Forum - basically asking if anyone has any experience/recommendations about the pros/cons of setting this to Large or Small. Please respond over there. -

Any specific tips for successfully capturing Motorcycle License Plates?
[Note: Some Hikvision specific questions, but I thought the LPR forum might be better to post in] Summary: I've been using a couple of LPR camera's to successfully capture license plates in our neighborhood for several months. As part of that, I did a fair amount of stress testing at our two... -

Funky problem upgrading firmware on DS-2CD5526G0-IZHS
Long-time lurker posting for the first time ... hoping someone will have a suggestion about a funky problem upgrading the firmware on a DS-2CD5526G0-IZHS. I've chatted with the Hikvision Tech Support folks, but their solution is to send it back for repair and I'd rather not have the...
