    Does your Dahua IPC-Color4K-T keep time?

    I just realized that my Dahua IPC-Color4K-T kept time even though it was blocked from internet access and doesn't know the internal network time server. Edit: I meant I powered it off, then plugged it back in, and it still kept time. Does it have a battery and real time clock inside? My...

    What causes these artifacts when camera seeing moving person?

    Using network monitor while viewing stream, I see 17mbps, which is the max bitrate. So...I think the network is OK right?

    What causes these artifacts when camera seeing moving person?

    Yes, it's going through the router. I've not had any issues with my network speeds. I regularly get get just over 100 megabytes per second (bytes, not bits) to my NAS. I'll see if lowering WDR and try again. Edit: looking at windows network monitor, I'm hovering around 17mbps, which is what...

    It's during live view.

    What causes these artifacts when camera seeing moving person?

    This is in broad daylight, so there's plenty of light, not sure why. This is on the new Dahua IPC-Color4K-T. https://i.postimg.cc/BvsjSxT4/weird-artifacts.jpg For encoding, I've tried h265 as well as h264. Backlight set to WDR. Besides the weird artifact, it seems like when I walk into the...

    Turn on Dahua LED via API?

    Oh, if you can share how you're doing the profiles, maybe that'll get me started. From what you said, it sounds like maybe you use a python script to do request.post with fields associated with the "button" on the interface?

    Worlds First Review - Dahua DH-IPC-HDW5849H-ASE-LED / IPC-Color4K-T - 2.8mm Turret

    @EMPIRETECANDY, can you share the settings you used for the IPC-Color4K-T? I've been trying to get mine to look good, but it's all over-sharp and things basically get illegible.

    Turn on Dahua LED via API?

    Is there a way to turn on the Dahua camera LEDs programmatically via an API call? Like for the IPC-Color4K-T, instead of setting a schedule or whatever, I'd like to send a API call to the camera to turn it on, at some level.

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    Oh I was aware that the lenses are fixed, meaning they're a single zoom level and you can't zoom in or out. But I thought even fixed lenses are capable of changing the aperture (impacts depth of field and light sensitivity) and focal distance (where the focal point is). I think the focus bar...

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    When you change the focus slider, is it changing the depth of view or maintaining the same depth of view and just adjusting the focal distance? I'd imagine any changes to the depth of view would require changing the aperture, which means that more depth of field would result in less light...

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    Do you mean it's not able to capture motion at night without a lot of ghosting and artifacts?

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    I think IR light reflects more strongly than visible light. So the bugs flying near an IR camera messes with the image a lot more than visible light camera. It's like a strong glare.

    Worlds First Review - Dahua DH-IPC-HDW5849H-ASE-LED / IPC-Color4K-T - 2.8mm Turret

    Thanks for all the info in this thread. Does anyone know if the LEDs on the camera can be controlled via API? Rather than setting the LED brightness based on day/night mode, I'd like to just be able to control the brightness with an API call.

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    Thanks to @Santeesticks and @sebastiantombs for the comparison. I wonder if the LED lights built into the camera can be controlled via API? So instead of the LED being on same brightness all the time, I can dim them or brighten them using a command sent to the camera?

    IPC-T5442 (4MP) vs. new IPC-Color4K-T?

    I guess some time has passed since the new IPC-Color4K-T came out. I was wondering if anyone went from the 4MP IPC-T5442 to the 8MP IPC-Color4K-T? What was your opinion of the nighttime performance? Was it worth the upgrade for you? Any gotchas with the upgrade that wasn't obvious in the...

    do you need to reboot regularly?

    Thanks for the ideas. I don't have an SD card in there, and haven't updated the camera recently. I leave most of the AI stuff to a server, so no fancy AI running on the camera itself. When there's BI connection issues, I also can't access the camera web UI. Good idea about the factory reset...

    do you need to reboot regularly?

    I have the Dahua IPC-T5442TM-AS. It's been running pretty solidly for 2 years, but the last few weeks I've had to restart it (unplug the POE, replug the POE) in order to get access to it again. I notice this when BlueIris shows the camera as offline/unreachable. Once I unplug and replug the...

    Difference between Dahua VTO2301R-P and the larger VTO2201F-P?

    Do you think the smaller one gets less glare from sunlight? I thought the bubble lens might make glare worst, but I don't know.

    Difference between Dahua VTO2301R-P and the larger VTO2201F-P?

    From the specs, it looks like the new VTO2301R is skinnier and has a ever slightly better sensor (1/2.8" vs 1/2.9"). Is that the jist of the difference? Otherwise, they function the same, including the SIP functionality? I read there's no way to make the IR turn on for the bigger VTO2201F...

    Dahua IPC-T5442TM-AS users - what firmware are you on?

    I have a IPC-T5442TM-AS, running firmware "V2.800.0000000.10.R, Build Date: 2019-11-18" I was wondering what version you guys have on yours? I'm looking to upgrade firmware to see if it fixes the day/night profile switching and to see if newer firmware does a better job with exposure and...

    Is there an API for changing night/day modes on Dahua?

    Oh man, it's so good to hear that I'm not the only one having issues with the day/night profile on dahua. Sometimes you work on issues on isolation and just think you're the only one dealing with a problem. I'm so confused what even is the issue. Sometimes the image is great at night...

    Is there an API for changing night/day modes on Dahua?

    I have a Dahua IPC-T5442TM. Is there anyone to remotely change the Day/Night mode? The built-in time based one isn't very good since lighting conditions change by the day.

    weather proof external microphone recommendations?

    I read a very good review for the Microseven microphone, but it's a pretty dated review. I also read a good review for the Hikvision DS-2FP2020. Are there any other ones to consider? How does the Microseven compare against the Hikvision? I had the impression that the Hikvision is more...

    Android app to talk/listen/view Dahua VTO2202F doorbell camera?

    Hi, Does anyone know of an Android app that can do 2-way audio with the Dahua VTO22xxx doorbell cameras? I know Dahua itself provides the DMSS app. But I kinda don't trust it. Since the VTO22xxx implements standard video and audio interfaces, wondering if others out there has had good luck...

    What doorbell camera in 2022?

    Thank you for the details. Regarding the DMSS application, what's the actual name of the app? Is it available on the Android playstore? Wondering if it's something specific to Dahua or some other generic DMSS app that uses a standard protocol? As for notification on button press - if you're...

    What doorbell camera in 2022?

    @Holbs , seems like you've got a lot of this figured out. Maybe I can ask how you have yours set up? Regarding #4, it sounds like maybe you use some kind of integration to know when the dorobell button is pressed, and that triggers some kind of cloud-based notification (PushOver, Telegram...

    Dahua VTO2201F doorbell camera - how to set DHCP?

    If you don't have a master list of all your static IP assignments, how do you keep track of things so you don't get collisions? You might have a device that's not currently powered on and connected (for example, a camera you plan on using but currently isn't, or something you were playing with...

    Blocking IP camera from internet - via MAC or IP address?

    Is there a "right" way to block IP cameras from internet access? If you block via IP address, do you have to block both the IPv4 and the IPv6? Or does blocking via MAC solve both IPv4 and IPv6?

    Do you block Blue Iris from internet access?

    I guess it comes down to how much you trust Blue Iris maybe.
