    Anyone here write ONVIF code? How does Dahua request an ONVIF sub-stream profile?

    I recently set up an ESP32 camera for the first time... Lots of fun... but I immediately realized that ONVIF support would make it much more useful. Did you ever figure out your ESP32 ONVIF problem? If you're willing to share your code I would be happy to see how my LTS (Hikvision OEM) NVR...

    Recommend a portable indoor-rated general use wifi camera with IR and ONVIF?

    I have only tried autotrack with kittens and it didn't work at all. But I think it's looking for human shapes, not just any movement.

    Recommend a portable indoor-rated general use wifi camera with IR and ONVIF?

    Got this camera yesterday and I'm very happy with it, thanks again for the recommendation. Seems to have perfectly civil ONVIF compatibility so it was no trouble to hook up to my LTS NVR. I haven't tried RTSP yet but I am sure it will be no trouble. The various Amcrest apps and the software in...

    Recommend a portable indoor-rated general use wifi camera with IR and ONVIF?

    Thanks. I can use a very close minimum for some things I want to do but I realize I may not be able to get one cheap camera that does it all. I'm ordering this one for the new kitten room though, thanks again for the pointer.

    Awesome, thanks for clarifying! Edit to add @wittaj since you have that Amcrest... Can you tell me what the approximate minimum focus distance is?

    Recommend a portable indoor-rated general use wifi camera with IR and ONVIF?

    Thanks @wittaj! Looks like that one doesn't actually have auto track but this is the kind of suggestion I am looking for! This one does list autotrack for about the same price. The manual does mention RTSP so there's probably a way to hook it up to my NVR. However, the one you linked made a...

    Recommend a portable indoor-rated general use wifi camera with IR and ONVIF?

    I'm finding many occasions where I would like to place a camera temporarily, so I'd like to find a generic wifi camera that I can use with my existing LTS (Hikvision OEM) NVR. 1080p wide-angle would be fine, it doesn't need tons of megapixels. It should have good IR illumination built in. It...

    What are the go-to cheap to midrange PTZ cameras today? My Huisuns still work, but... that can't last!

    Based on the reliability reported over the years I assume that adds up to one working camera. :) I've been lucky with mine for sure.

    What are the go-to cheap to midrange PTZ cameras today? My Huisuns still work, but... that can't last!

    Thanks much for the reference. That's a substantial upgrade for sure! I do heavily use my back yard PTZ, 'cuz it's big and interesting animals show up a lot, so this looks super. I'll look for threads on this baby.

    What are the go-to cheap to midrange PTZ cameras today? My Huisuns still work, but... that can't last!

    I have 2 Huisun 10x PTZs, one V1 and one V2. They have both lasted years in Seattle weather. The only problem is that I think the long distance IR illuminator on the V2 bit the dust. They have been a lot of fun and I would like to figure out a replacement/upgrade path as I know they won't last...

    VLC RTSP main stream from LTS (Hikvision) NVR freezes after a few minutes; substream OK

    I can access a video feed from my LTS NVR with VLC and this kind of URL: rtsp:/admin: PASSWORD@192.168.1.15:8554/Streaming/Channels/502 Note the last digit: 2 is the substream and 1 would be the main stream: rtsp:/admin: PASSWORD@192.168.1.15:8554/Streaming/Channels/501 Unfortunately, after...

    LTS (Hikvision) NVR & VLC: Can't see main stream via RTSP, only substream

    HOLY SMOKES That worked! In the VLC Open Stream dialog there is a buffer setting in milliseconds... It defaults to 1000 ms. I changed it to 100 ms and I have a beautiful 2688x1520 picture!! Best forum followup ever, thanks @najman!

    LTS (Hikvision) NVR & VLC: Can't see main stream via RTSP, only substream

    I will double check that, but I am 99% sure my NVR only supports h264. However in related good news, my NVR maker has released new firmware which allows you to log in to the NVR and see video with a modern web browser--instead of relying on an ancient Internet Explorer plugin. So while VLC may...

    Get still image through URL from Hikvision NVR [SOLVED]

    My notes on direct camera access look the same as yours--and it has never worked for me either!

    Get still image through URL from Hikvision NVR [SOLVED]

    This is what worked for me. Video (change the "X" to one of your camera numbers. Substream only available for some reason) rtsp:/NVR-IP-ADDRESSS:8554/streaming/channels/X02 Stills (change the "X" to one of your camera numbers.) http://NVR-IP-ADDRESSS/ISAPI/Streaming/channels/X04/picture...

    Get still image through URL from Hikvision NVR [SOLVED]

    Ah yep, I am missing that section of the advanced settings entirely. I'll check for a firmware update. I may be out of luck though My application was just trying to get an image into a web browser, it's very convenient sometimes. I have found partial success addressing the NVR

    Get still image through URL from Hikvision NVR [SOLVED]

    Where are those settings? I have nothing like that in my LTS cams (rebranded Hik) model CMIP3042W-28 firmware V5.3.6 build 151204

    Best deal on Imporx (Huisun) v2!

    My 1x v1 and 1x v2 are still hanging in there. Both of them make a little buzzing noise now though! Is there a go-to replacement for these guys when they poop out? Anything cool, affordable, and maybe even ... reliable?

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Thanks fellas, I will give it a shot. I'm baffled as to why VLC and the other RTSP viewers I tried would barf on these streams.

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Looks like I will have to do that next so I can get a better look at the cameras with a tool like ODM. (As far as I can tell there is no onvif access to my NVR, just the cameras.)

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Just tried reduced iframes too, all the way down to every frame. No change. I feel like eventually someone will come along and say, oh, you could never use rtsp for main streams on that brand of camera, what were you thinking? I wish they would hurry up and get here. ;) This is irritating...

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Yes. All the xx01 streams do the same thing -- they connect, but show a black screen. All the xx02 streams will work but only in CIF resolution. I just used ffmpeg (ffplay) to connect and it happily connects to all the streams, but shows garbled video for the xx01 main streams.

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Makes sense, thanks. Unfortunately I cannot find any info on how to tickle my NVR via Onvif; not even sure it is possible. But, my NVR exposes the cameras to my normal LAN IP range by appending a port to the NVR's IP address. For example, I can access camera 7 over HTTP this way...

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Yeah, that is a pretty cool looking tool, but it does not detect my NVR and I cannot find anything about how to get ONVIF services over HTTP with my gear so I guess I am out of luck. Bummer!

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Thanks, I will look up that app. This is in reference to ONVIF Device Manager, right, not elsewhere in my web config? Just making sure. Thanks again! Edit to add: Took a look, but all my cams are "behind" my NVR. I can address them directly through port forwarding that the NVR provides, but...

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    The same, h.264. It's the only option offered on my camera. I think if I do a firmware update on the cameras I can get "h.264 zip plus" as an additional option, but I can't tell if it is a standard or proprietary BS so I have not messed with it.

    Using VLC to watch RTSP streams, I can only view CIF resolution (352x240) - why?

    Been having trouble viewing RTSP streams from my LTS/Hik gear and I finally figured out the key variable: video resolution. I can view the sub-stream as configured below; if I increase the resolution to the next option up, 640x360, VLC connects but gives me a black screen. The main stream...

    LTS (Hikvision) NVR & VLC: Can't see main stream via RTSP, only substream

    This is the format of an RTSP URL for my NVR: rtsp:/admin:*******@192.168.1.15:8554/Streaming/Channels/50x ... where x is 1 or 2 for main or sub stream. (LTS uses 8554 as the RTSP port on the NVRs.) 502 works fine but obviously I would like higher quality. When I try 501, I get a black...

    Helping my vet choose an indoor PTZ to monitor kennels--help?

    I have actually thought about suggesting that for their boarding operation. For the hospital side it might not be appropriate, some of the patients are in dire straits and heavy medical stuff could go down that you might not want the owner to see unexpectedly. There are also considerations with...
