Certainly the security breaches IP cams may present are well worth looking into before buying one. Very often they are set up with a mobile phone and want the password to your router. Then they get in touch with several IP addresses in China, Google and others you may not want them to contact.

There are websites showing livestreams from hacked cameras.

As far as security for IP CCTV cameras goes:

1) Use wired rather than wireless if you can. If have to go wireless put the cameras on their own SSID/VLAN, if your wifi access points don't support multiple isolated SSIDs/VLANs upgrade to one(s) that do.
2) Always, always, put cameras on their own dedicated VLAN or an isolated LAN of their own. Don't allow them Internet access and don't buy cameras that require internet access.
3) Put a firewall between them and the rest of your network and limit traffic to and from the cameras to what is only strictly necessary and nothing more.

All the above presupposes that you have networking kit that is up to the task of isolating/firewalling a subnet and that you're competent to use it to do that. If you don't have the hardware capabilities or expertise I'd suggest that you'd be better off with old fashioned analogue cameras and a dedicated CCTV PVR to wire them back to.

IP CCTV cameras are a potential security nightmare if not handled with due diligence and a proper understanding of how to mitigate the risks.

I personally wouldn't do IP unless I could set it all up on its own switch/router completely airgapped from the "real" network and some old laptop or PC as the "monitor". I mean, used SOHO networking gear is so cheap... and even if you do find it is compromised after the fact, who cares? It cannot get out to the intardnet.

The main reason to go IP is the convenience of using cabling already in place; this is one case where it just plain makes sense to keep it all isolated. Full stop.

Is there a problem with the forum's PM system? I sent a PM at 12:55 and it still shows up in my outbox, and checking in my sent folder, its not showing in there?

so i got the pos karaoke machine working.

probably a BIG mistake since now everyone who goes to that bar will try to talk me into fixing their crap.

where do i draw the line? coffee makers? microwave ovens? breast pumps?

ps that karaoke machine must have been assembled by children. it astonished me how they took what was probably a good design and cheapened it down to a barely working piece of shit full of embarrassing bodges. it was purchased new, but the transformer on the main switching ps board had been replaced with one that was clearly not correct (but close enough to work). trouble turned out to be an open in one of two 1n4007's on the controller board that were in series so that their forward drop took the +5v rail down to 3.3v. took me a while to noodle that one out.

I have returned from a great vacation, or holiday if you will, in Florida. Drive home was a total PITA due to hitting rush hour traffic in DC and Baltimore but eventually made it home.

Still in "vacation" mode and still don't give a shit. :lol:

I fix things for friends on the basis that whatever it is would otherwise be thrown away. Usually it's something simple, such as corroded battery contacts in a trail camera that stopped working, or bulging capacitors in the PSU of a DVD player. Sometimes it's interesting to find out what went wrong, and I have to explain why it can't be fixed, or can't be fixed safely, and they're better off buying a new one.

Most new items are not intended to be repaired. There's very little that can be done with modern cars without a ramp and basically full garage facilities.

Years ago, there were electronic repair businesses; TVs, radios, tape recorders etc. I doubt there are many left and for good reason. It would be hard to make a living fixing such things.

If the coffee maker or microwave is yours or belongs to friends or family, it's worth having a look. It could just be something obvious such as a contact which has worked loose, otherwise, refuse to get involved.

Oh, looks like it is a dragon... just the wings are small & gold or the cloisonne has flaked off. I think I recognize the artist' style... if I'm not mistaken, same person who did my little waving dwagon...

[EDIT]

Did a little research; it appears the pin is official swag from the Balloons Over Iowa aviators' club, and mnementh was a real balloon piloted by well-known balloonist Annie Laurie Jones/Points, ca 1985. Presumably it bore that ID pattern.

huh.

Some good news on the test equipment front:

I picked an HP 6205B power supply up on the way home from work tonight for $20.

Image

I have another 6205B that's branded HP Harrison. It's in the pictures of the 427A testing I was working on. I still haven't had a chance to take any pictures of the other stuff I picked up recently.

Otherwise, it continues to be not so great. The vandalism streak apparently continued and several of the boards in the gate at the end of the neighbour's back yard gate got kicked in. I don't know what's happened to this neighbourhood, why it's gone downhill so fast. I took tomorrow off to take my cat to the vet first thing tomorrow morning. He's resting with me on the couch right now and trying to act normally but he doesn't have much energy. He suddenly barely eating and drinking and not using his litter boxes. He's been in them, I can see where he's pawed at the litter, but he's left nothing in them. Hopefully he'll be alright.

Nice score on the power supply, and I wish you well regarding the vet visit - sincerely hope it’s something minor and that your buddy is back in good health quickly. Shame they can’t tell us what ails them. Good thoughts inbound.

had the same symptoms with our duffy last year. was in the basement working on a wonky SA and noticed he was in and out of the litter box multiple times with no result.

turns out crystals in the urinary tract block the flow in male cats. very very bad.

if you get him into the vet quickly they can get a catheter in and then push lots fluids to flush him out.

duffy was good as ever in 3 days.
