Thanks. I wrote a custom card in javascript using customElements.define() and subclassing LitElement. Then in render() putting something like html1<ha-card><h1>...`. The guts of it is css grid. For the APIs, I use the Dahua NetSDK at Dahua Partner Alliances . That uses the 37777 interface I...

Hi All, I pulled together a bunch of instantaneous performance metrics from my Dahua cameras and NVR and made a crude display for them in Home Assistant. Here's what it shows: It looks like it's possible to get the exposure numbers the camera is using, overall ambient brightness, video stream...

Just to follow up on this, I ended up doing a hard reset (holding that button by the SD-card for 10 seconds), and now snapshotting seems to be working more consistently. And I've kept SMD disabled so am only using IVS.

I managed to read out CPU load and memory usage, (using the 37777 interface). CPU usage hovers around 45%, and not much that I do seems to affect it, including enabling SMD or switching to H264. It's quite possible that it could be the hardware doing the JPEG or H264/H265 processing that's...

I turned off SMD and motion detection and all substreams. So I have just H265 on the main stream and two IVS rules on. And it is still stopping snapshotting. I can't believe that that is too much to ask of the CPU. Hrm. Josh

I saw your comment in another thread about CPU maxing out causing problems. How can I check the CPU usage? I'm running 10 FPS, with 2 IVS-rules and SMD, and H265 (maybe the H265 is stressing it out?).

Hi - I've tried two different SD cards, both U3 / V30. The first was Samsung Pro Plus 128GB. And I just now tried a Samsung Pro Endurance 256 GB. With the Pro Endurance, I just had an IVS event, but it didn't start recording snapshots until about 15 seconds after the start of the event...

Great point about flood light interfering with image exposure. I started a different thread about deterrence: Deterrence in urban environment

Hi All, I live on a dense, urban street with neighbors on all sides. The street has people walking down it periodically, even through the night hours. Flashing bright lights or even playing audio probably would annoy the neighbors. And @wittaj makes the good point that flashing a bright...

Hi All, I just got a IPC-Color4K-T and the web interface only lets me specify rectangles for a privacy mask. On my 5442 camera I could specify triangles or other shapes. Has anyone else had the ability to draw other shapes on their Color4K-T/X ? -Josh

Hi, I recently bought the IPC-Color4K-T, updated to the latest firmware V3.120.0000000.39.R, Build Date: 2023-09-18. I have it configured to record video and snapshots to the SD card during SMD or IVS-rule events. I noticed that it sometimes stops recording snapshots during events and won't...

Yeah, I could easily believe that the relative performance tradeoff between H265 and H264 varies based on the specific environment, windy-ness, as well as of course the particular camera hardware. We've unfortunately had a few incidents of crime recently that I caught on camera. One ended up...

In the experiment I did today, the H265 clip was about 1/4 the size of the H264 clip (roughly 2100 kb/s vs 8200 kb/s). I'm using VBR with H265. I just took a closer look at the frames. I can't tell a different between the non-motion areas of both clips. I do think I can see a slight difference...

I just played around my 5442 camera settings, comparing: H265, smart-codec, VBR, quality 6 (best), 8192 max bit rate H264, General, CBR, 8192 constant bit rate Both at 10fps. I then walked in to the side of the frame, and alternated between moving around and being still. I downloaded the AVI...

Yeah, I'd read on this forum cautioning against H265. But when I tried walking down my street, recording in H265+VBR vs H264+CBR, both recordings looked basically the same I think. Is there something I could try doing in front of my camera while recording that would highlight the problem with...
