  • Great.

    1: How do I get an RTSP or ONVIF? Every time I try to buy one, the stuff that is recommended is no longer available, or practically only available in US. (I haven’t checked in months maybe years, but this is where I usually get stuck.)

    2: So I get a camera, and I have an rpi or PC-based server with storage. I can see a stream, but that’s just an extra eye. How do I turn this into a surveillance camera, so I get a notification when there’s movement, and an archive of people in the monitored area?





  • Oooh yeah, ISDN. My cable solution that I got in year 2000 (to answer OP’s question) didn’t work very well, and DSL wasn’t an option yet I think.

    For those ready to listen to my nostalgia:

    ISDN was awesome because even the smallest solution had two channels. So two phonecalls on one line. Great for businesses. Also, a channel had 64 kbit, slightly faster than the analog modems which I think maxed out at 54 kbit, which was often unlikely to be reached.

    But the trick is, the two channels could be combined to 128 kbit. An incoming or outgoing phonecall would simply reduce the speed back to 64, instead of interrupting the connection.

    Although I paid by the minute, and using two channels doubled the cost, so I usually only used it when I was literally waiting for a data transfer and would be paying the same price anyway.

    Actually, I think my ISDN would count as dial-up, as I paid by the minute.






  • I spent a few minutes researching this, and I still have no idea what the problem is. Or any motivation to keep researching.

    Honestly, I might be part of the problem. I’m a white guy, and there are basically no black people in my life. I don’t see any in the streets, at work, at home or here. Especially here, I have no idea who anyone is.

    Basically, I have no reason to get involved. However, I don’t want to be part of the problem. So if you spoonfeed me information I can use to make life better for “the blackness” (I’m very confused about the terminology), I will happily read it and try to remember it.

    So don’t just tell me the solution, none of the TLDR makes any sense to me. Spend a few words on the problem.

    As far as I can tell, there’s basically two kinds of people:

    1 - People who just don’t care about other people in the Fediverse. They will not read any of this, there’s nothing you can write here that will change anything for them.

    2 - People who are trying to be nice, but don’t always succeed. They will listen to advice, but nothing will change by telling them to be nice, be less racist, or to listen to people even if they are black. That’s what they are already trying to do.


  • Because it draws those “pixels” as the signal reaches the monitor. When half of a frame is transmitted to a CRT monitor, it’s basically half way done making it visible.

    An LCD monitor needs to wait for the entire frame to arrive, before it can be processed and then made visible.

    Sometimes the monitor will wait for several frames to arrive before it processes them. This enables some temporal processing. When you put a monitor in gaming mode, it disables (some of) this.
