Re: Filter - odd behavior with "and" and "or"

Expect nothing, then you won't be disappointed.

However, I might expect a bald "-3" of a timestamp in Unix to mean 3 seconds before epoch (i.e. Wed Dec 31 23:59:57 GMT 1969)

This relates to events from before ZM existed :)

Re: Detect velocity of anomalies

(The guy with the gum must have walked up to the doorbell first.) Loom would just be a third dimension for that velocity. That would be the obvious first response, unfortunately he/she had some crab DNA, and came in from the side so as to evade capture. I'm not making this up ;) I'm doing the code ...

Re: Detect velocity of anomalies

I guess most people, like me, have their cams mounted out of reach and pointing downwards. True, but there are plenty of e.g. Amazon style doorbell cameras that point forward at around face height. That's the sort of thing I was thinking of. There are cases it won't catch, like if all the world is ...

Re: Detect velocity of anomalies

calculate a centre of gravity of the alarmed pixels/blobs ... That's the rough idea but some extra polishing would also be worthwhile. Be aware this algorithm will fail if a burglar walks directly towards the camera (sure, they will get bigger and Bigger and BIGGER, but their centre-of-blob will re...

Re: Camera security question

Why would we buy something like that? Ignorance. In the nicest possible way :) It's not always possible to know that something is insecure until someone discovers it (having pulled apart the firmware to discover the permanent non-documented non-changeable test user, or observed unusual network traf...

Re: Unusable picture (b/w and shifted) using 1.34

(Assuming your doors are vertical!)

Zooming in, it looks like it's off by *1* pixel per line (declared width 1 pixel less than actual width), and it IS in colour, but seems to be using some weird colour palette of 7 pastel colours, which is not the best ...

Re: Docker subforum

I just tested it, never having looked in there before :- "Docker You do not have the required permissions to read topics within this forum." This happened accidentally on one of the other sub-fora, it was a permission issue I think ... See :- https://forums.zoneminder.com/viewtopic.php?f=13&t=28941 ...

Re: Y-Cam HD-Pro

If the first three digit pairs aren't in any of the various OUI / MAC address lists findable on Google, then it's either not a MAC address at all (could be a huge random number allocated in production?) or the company is just using made up MAC addresses on the basis of -- "who cares?"

Re: Camers not viewable on lan when no internet connection.

I use local IP address for this situation, usually https://192.168.1.X/zm instead of the DNS name. Your browser may cry and whine about cert mismatch...but this approach always works for me. Also, the monitor source should be local IP, not any alpha name. Using local IP addresses should work for lo...

Re: Y-Cam HD-Pro

... after inserting the MAC address of your camera, do remember to try base64ing (encoding) it back the other way :) I don't know whether the raw or encoded password is what is needed here! Does your MAC address look anything like (DC:50:80:xx:xx:xx) -- if it's nothing like that, I'm probably wrong ...

Re: Y-Cam HD-Pro

The OP has only one post (the one you replied to) so likely not about anymore -- but to sniff TCP traffic and discover these things, Google "tcpdump" and "wireshark" -- they can be very useful for spying on IP based devices to see what they are up to, including "Why can't I find the IP address of my...

Re: USB camera stop working after a while hardware\software problem?

"/dev/video0 /dev/video1 /dev/video10 /dev/video11 /dev/video12" So did you run that command when ZoneMinder was NOT WORKING? (Apparently refusing to capture from /dev/video0 as per your original screenshot?) That's a lot of video input devices. But 10,11,12 are because of https://www.raspberrypi.or...

Re: Pattern over dark areas

In the second picture, unless your camera is full of tadpoles, it looks like a printed circuit board pattern, maybe something like a BGA chip, but very zoomed in. https://macrofab.com/blog/escaping-bgas-methods-routing-traces-bga-footprints/ I would guess that with the IR-cut filter in place, you ar...

Re: USB camera stop working after a while hardware\software problem?

First problem :- You are using a Raspberry Pi with an inadequate power supply, which will cause you all sorts of odd behaviour, crashes, data corruption, problems with plugging in USB devices ... Under-voltage detected! That aside, when you plug in the USB camera and it works, you have a "/dev/video...
