Re: Connecting Wyze V2 to Zoneminder

Hopefully Wyze will be kind enough as to provide you with the camera stream paths, but after that, you may have to use wireshark, and do some digging. Any good camera will include the stream paths in the User Manual, or they will be in the ispy website. See: https://wiki.zoneminder.com/Finding_Camer...

Would you be so kind to write me a hint, which options in Kernel config should be set off regarding above you mention in a code.
Thanks for pointing that out. I've updated the post.

Disabling Spectre and Meltdown mitigations (speculative execution)

Since the speculative execution CPU vulnerabilities have come about, all fixes and mitigations have come at a cost to CPU intensive applications such as Zoneminder. Basically, all PCs became slower in 2018. This is a significant loss for Zoneminder and we should document ways to disable these fixes,...

Re: Which stream is more efficient?

I've found that the best performance is with Nodect, and external motion detection. There is a downside, however, that you have to setup the external motion detection.

In this case, you'd have the 3MP stream, and then Nodect on it.

Re: Can not view RTSP camera stream

4K on a raspberry pi 3, I don't think is ever going to be possible. Unless you slow down the frame rate dramatically (probably <1FPS). I've done some benchmarking (link: https://forums.zoneminder.com/viewtopic.php?f=6&t=27938) You will need to lower the resolution at the camera or use a lower resolu...

Re: Event duration while playing back is very long

Check the logs.

Does JPEG frame saving work? the library mp4v2 is being phased out, so this has broken H264 encoding on Debian 9, though there is a guide in the wiki for it on Ubuntu 19.04

Re: Limiting the FPS of an RTSP stream using H264 passthrough

FPS limiting from ZM side seems to be frowned upon for H264 streams. FPS limiting should never be done from ZM side (with one exception - local cameras)*. It doesn't matter if it's an H264 stream. This seems to be a consistent mistake from people on these forums. I don't understand why. Back to the...

Re: Can not view RTSP camera stream

It's possible to get 1.30.4 in ZM RPI if you use the official Debian (arm) apt repository. Raspbian only has 1.30.0 in their repos. If you have to ask how this is done, you probably shouldn't bother (there are potential issues with mixing repos). Just use 1.30.0 Try LibVLC? Although I'm not sure if ...

[BUG] Runstate Changes in 1.32+

In 1.30.4, with the Filter on Runstate patch applied, if you are to 1) add a Run State to a filter, save and go back to console 2) then edit that Runstate (say you change a camera from modect to nodect, or add a camera, or whatever), and save it, you will have the corresponding filter with the run s...

In my experience, cameras dropping out appear to be brand dependent.

What brand of cameras do you have?

Re: ZM Video Sluggish

To be clear, it was the faulty HDD not the VM that was causing the failure of H264 passthrough. It worked in the VM before the HDD failed, though the virtualization (and doing other things on the server at the same time) might've caused the HDD to fail faster.

Re: Sports recording setup (3 cameras)

Perhaps my initial explanation was a bit confusing here - by 50-80m distance I thought the distance from the cams to the central point (router/PC). That distance is only limited by whichever POE spec your equipment is rated for. I would recommend you use the real POE - the 802.3af - not the passive...
