Re: Rpi 4B-8G, 2T SSD, 10 IP cams, 203,000 events-Offline

When I touched the aluminum case, I got a large snap and electrical shock from static electricity. The static discharge immediately shut down the Pi5. I would expect that the power supply you are using is a "floating output" (not referenced back to mains earth) and that means the Pi, and ...

Re: Pixel shifting

I have a few wired Lorex cams with this problem, but this happens with other cams as well. I have a short video that shows the problem, but its 100MB so I cant upload it here. If you could watch it, every few moments you'd see the image shifting just a few pixels one way and then another, also the ...

Re: TCP streaming not recording video

Thank you for the speedy reply. The 8080 port seems to work, even if it is not http - could this be the cause of the lack of video? I do not understand your comment TCP is a method, not a protocol In the Source tab of the camera settings the second section down is labelled Method, and provides a pu...

Re: Run filter after a certain time of day

This is an old thread, I know, but I'm running zmfilter.pl in crontab to remove events with fewer than a couple of alarm frames, and I cannot for the life of me get it to output the results to a log. A log is not critical, but I'm just wanting to see that the filter is working. Any hints about how ...

Re: solar camera IP discovery & rtsp

mikb - I saw you use the word torch. Just for kicks, I tried google translate. It has no idea that a torch might be a flashlight to many of us... Sorry, I forgot the i18n disclaimer/inclusion ;) Yes, in the UK a torch is battery powered light -- not a flaming oil soaked bit of cloth on a stick for ...

Re: Error writing packet: Invalid argument

Normally we detecte out of order packets and default reorder_queue_size to 2*keyframe interval, which seems to be good enough for most cameras. Those logs say reorder_queue_size=0, which means it is either very confused or there is some case that we aren't handling right. You can manually override ...

Re: Infrared reflective tape

Take a bright torch (flashlight) and check it -- look down the axis of the torchlight and see if the light is coming back at you ;)

Application provided invalid, non monotonically increasing dts to muxer in stream 0 I used to see this when transcoding some videos in FFMPEG. The dts (display time stamp) of two frames in succession are the same, which is viewed as some kind of heinous error ... surely FFMPEG should have a --suck-...

Re: File System Recommendation

Your file system being "full" due to lack of inodes is certainly a real thing (and confusing, if you ever come across it). I've never tampered with the inode-count settings, but a quick man mkfs.ext3 reminds me that you can set this when creating the filesystem. Not sure you can update it/...

Re: How to do UDP?

I don't think TCP guarantees order. It just guarantees that the packet will get there eventually. Which is why we actually prefer UDP over TCP for live streaming... because if the packet is late, we likely don't care anymore. But then we need buffering... From what I remember of this stuff from Com...

Re: Infrared reflective tape

Anybody got a good suggestion for some reflective tape that will show up nice and bright when a camera is in night mode with the infrared LEDs shining? I got a camera in my workshop that has a view of the deadbolt. If the lights are on I can barely make out whether the deadbolt is locked or not. If...

Re: The memory fills progressively

OK, so at least you know what exactly you are looking to fix now ;) Your capture processes (taking data from the camera) are not starting and running continuously. They are instead getting hung up, so ZM sees this as a fault and starts a new one -- it's persistent in trying to keep your security sys...

Re: The memory fills progressively

How many cameras do you actually have? The count of tasks in those screen shots seems to be climbing too, is it possible you have more capture processes than you have cameras (e.g. something is causing them to stall, so ZM launches a new capture process, and again, and again, for every camera) ? Tha...
