    How to setup Dahua IVS with BlueIris?

    With the help of this thread, I finally managed to get Blue Iris to record on IVS events. I'm not sure what the issue was, probably the ONVIF source = 00000 and the Alerts > Motion Zones: uncheck. But one issue that I have is that the recording starts late. It could be the IVS fires late as...

    Why I like Continuous Recording (aka 24/7)

    @samplenhold , I might have missed it, but I'm curious what is your setup? What do you use to record your footage and to trigger the alerts?

    Smart PSS not showing IVS triggers on PC NVR recordings.

    I have the cameras sending IVS alerts to DMSS without P2P as long as I am on the same WiFi, or via VPN (and the app was not closed for a while) The issue is the alerts are useless if you don't record to SD Card or NVR because when recording to NAS/FTP, you cannot view the video from the app. I...

    Brands with a strong mobile experience?

    I think you take my question out of context. @bigredfish says his DMSS shows them picture of the event trigger action. But I don't see where he says if his DMSS connects to his camera or his NVR. I honestly don't understand why this question is so difficult to grasp. Since DMSS can connect to...

    Brands with a strong mobile experience?

    This isn't accurate and isn't answering my question. The DMSS app is the mobile app for Dahua, but it can be used with more than their NVR. It can also be used with their cameras directly (without needing an NVR) and other products such as IVSS, VTOs and access devices.

    Brands with a strong mobile experience?

    What does your DMSS connect to? Camera or NVR or something else?

    Brands with a strong mobile experience?

    Isn't the Blue Iris app crap? I haven't bought it so I'm not sure, but the reviews are not that good. @Sybertiger what solution is that? What camera, mobile app, NVR/software?

    2023 and 2024 Models Update

    Do any of the new versions support playback from NAS or still only SD card?

    IPC-HDW5442TM-ASE with the I.R. vs IPC-HDW5442TM-AS-LED with L.E.D.

    I'm am comparing very similar models from the same manufacturer. I would expect them to at least be consistent when testing, especially on models for which the only difference is the IR vs LED capability. Why would they pay different marketing tricks for their own cameras? I would expect the...

    IPC-HDW5442TM-ASE with the I.R. vs IPC-HDW5442TM-AS-LED with L.E.D.

    Strange since according to Dahua' datasheet, the sensitivities are: IPC-HDW5442TM-ASE (IR): 0.002 lux@F1.6 (Color, 30 IRE) IPC-HDW5442TM-AS-LED: 0.0016Lux/F1.6 ( Color,1/3s,30IRE) So I would expect the LED to have slightly better nighttime performance than the IR one. Refs...

    Dahua T5442TM-AS quick review

    Thanks. Do you think the IR lights are better? At least I have a better chance of color with with LED. For the new version, is that a Dahlia? Can't find it on their website.

    Dahua T5442TM-AS quick review

    I'm trying to decide between T5442TM-AS-LED and T5442TM-AS (IR). I usually have enough ambient light to stay in Color mode and I want to keep that. From your statement above, I understand that the T5442TM-AS (IR) is better in B/W mode than T5442TM-AS-LED because of the IR filter that is removed...

    font issues on Dahua IP cameras

    I'm getting the same "Failed to start playback. NETSDK returns error" as the OP and I'm also using a 4MP on a 1/3" sensor camera. Are you saying that if I get a better sensor size per MP, I will no longer have that error in SmartPSS?

    Smart PSS Error Help

    2023 update: :cool: I save videos to NAS via SFTP. I am getting this in SmartPSS for the same videos that I cannot playback in VLC, and coincidentally, it's where most of the interesting action happens :rolleyes: Is the video corrupted, what could cause this? It's quite a bummer that this can...

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    I got one IPC-HDW2439T-AS-LED from AliExpress and it was not the latest firmware. I upgraded it using the interface without problems.

    What do you think about DH-IPC-HFW2439S-SA-LED-S2

    I have both the 2MP varifocal IPC-T3241T-ZAS bought here and the IPC-HDW2439T-AS-LED and here are some screenshots for reference: The screenshots are tagged with the model name and the date. Unfortunately, I don't have side-to-side comparison of same position, angle and date, but I chose...

    Playback Dahua camera recordings on Android

    That's not a problem. I don't have an NVR and I'm considering Blue Iris. They have trial period for the VMS but not for the app. If the app could do playback reliably, it would be great candidate.

    Playback Dahua camera recordings on Android

    I have a standalone Dahua camera that I configured to record to SFTP on events. I use the (official) DMSS app directly (no P2P, etc) and it works extremely well for live view. At 1080p, I get fluid 500KB/s. If I go to playback, I can see the recordings on the timeline, but the timeline is very...

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    The one above is from Cloud Netvision Store. For most situations, I would go with Andy, but he doesn't have all options (e.g. I was looking for a LED cam version), and often goes oos (e.g. the 2 MP varifocal I bought last month is gone from the store). His Amazon storefront has only a fraction...

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    Lots of good warnings on this forum about the Chinese versions, but what about when the seller actively states they are international / Global version / upgradable ? I am a bit curious if anyone had any experience (positive/negative) with cameras from sellers making these claims. I would...

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    Ah, thanks for the clarification. It was because your original post had "IPC-HDW2439T-AS-LED-S2" on the first line and the Aliexpress listing picture with absolutely no mention of the other camera in the OP post, so I thought you were referring to that camera in particular.

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    I get all that, but your reply seems to imply that two cameras for the same generation and the same manufacturer same sensor size with the main difference being IR vs Warm LED will perform significantly different at night because... sensor size? I would like to understand what is your statement...

    Aliexpress Dahua IPC-HDW2439T-AS-LED-S2 and IPC-HDW2431T-AS-S2

    The Comparison is with the IPC-HDW2431T-AS-S2 that has the same 1/3" sensor size. Why would the HDW2439T-AS-LED-S2 perform worse for the same sensor size, please clarify the comment?

    The Importance of Focal Length over MP in camera selection

    Thanks for explaining the other points, but I have to ask: why h264 instead of h265? And how do you determine the bitrate(8192)?

    Asecam Cameras?

    While searching on AliExpress for Dahua/Hikvision/Amcrest cameras, I stumbled upon a recurring brand: Asecam. I searched the forum and oddly no results. So I search the web and found this interesting review: The guy seems to test pretty much all scenarios that I can think of at least. There is...

    The Importance of Focal Length over MP in camera selection

    This helps me narrow down my search and I conclude I first need/want a varifocal (turret preferred) 2/4 MP with a minimum illumintion between 0.002 - 0.004 preferably built by Dahua or Hikvision. The two options above fit this requirement but they are shipped from US to Canada, there's...

    The Importance of Focal Length over MP in camera selection

    This post is intriguing me a lot. From my understanding we have two cameras under the same/similar conditions with very different results: 5442-ZE 4MP set to 3.6mm digitally zoomed (IPC-T5442T-ZE ?? turret) - BW picture above 4MP, 1/1.8" CMOS image sendor 0.003Lux at F1.8 Min. Illumination...

    REVIEW: Budget 4MP Turret Comparison - IPC-T2431T-AS vs Chinese HDW4433C-A

    I wonder how this compares to IPC-HDW2431T-AS-S2 which is cheaper but on AliExpress. The minimal illumination is 0.01 as opposed to 0.008 with the T2431T, but I don't know if that would be noticeable. On the low budged side, there's also the Amcrest IP5M-T1277EW-AI, but I don't know how to get...
