I have the Dahua 4kt as my street camera. It isn’t terribly distorted when aimed slightly below horizontal. I like it very much because it gives excellent low light color footage, and the motion detection is very good, with few false positives when set correctly. I don’t know the other cameras.

Wonderful, if that's all you need. But if you get a second camera, you may want to switch between them. You may want to add in audio from a separate mic. You may want to use color correction that isn't built into your camera. Even if you don't want to do these things, someone else reading...

OBS is one of those amazing programs that is good for a lot more than any individual user employs it. That it is also free is hard to believe. OBS runs on sources and scenes. A camera is a type of source. A simple scene might have a single source. Once you have a scene, you can set up a...

I like light better than IR. I think it lets them know you're watching.

I'm not an electrician, but I believe they discourage multiple grounds, and want all the grounded loads to go to a single earth ground, often the cold water main, or a copper grounding rod. Apparently there is enough difference in the resistance of soil (especially if one area is wetter than...

Blue Iris on a ten year old Windows workstation is about as cheap as it gets.

Excellent discussion.

Welcome to the pond, GilFrog.

That's where building a solar light from components has an advantage. You can size the panel and battery to keep the light on through a Winter night.

Nice. That adds some curb appeal. I think 120v a/c is the way to go for most things. 12v is fiddly, but sometimes if something is remote or has to be independent from the grid, it's the best solution. It's also good from a permitting perspective sometimes.

Hi Fred, welcome. Sorry you're obliged to do the cameras, but you've done well to start with research and not just throwing money at a box-o-cameras from the local warehouse store. Don't be put off by the networking. You'll pick it up as you go, as most of us have. Just keep repeating...

Yes, quite right. They're a mix of 4k-t to 720p door stations. Most running around 2k resolution. The processor is an i5 6500. Still, I think a g4 should have no trouble with what he's doing.

Sorry Tony, I didn't read closely enough about the LoRa gateway cost. I think they run around $80? But I really have no experience here, although I keep thinking about experimenting. I flagged the article because the topic comes up periodically, not because I actually know anything.

I can see the LoRa being good for long driveways. I've read they have a couple miles of reception.

I'm running 9 cams on a g3 elitedesk 800 with no lag. Computer shouldn't be the problem.

The article says the unit they're selling is around $46 usd. My guess is that a cheap PIR, a lipo and a LoRa could be wedded for something less if one enjoyed the tinkering.

For whatever reason, maybe a bunch of leds in the strip has some capacitance, I see no flicker. Or maybe 60 cycles per second is faster than I can see it.

You might try getting a small solar panel, a sealed 12v battery and a cheap charge controller. That would let you put the panel where you want it, and where you can clean it. I have the above items powering my lighted house numbers. The charge controller will do dawn to dusk or a set time...

I have a dc led strip light running off the 12v ac my landscape lights use. A simple bridge rectifier does the job. The strip light was cheap, so I wasn't afraid to try it without a regulator.

We periodically discuss ways to trigger an alert when a mailbox is opened. I saw this about a LoRa PIR sensor that sits inside the box and sends a signal when the door opens...

Dahua support, at least their US branch, kind of sucks. Just curious, but who do you plan to recommend, now you're off Dahua?

I have a Trendnet and an HP OfficeConnect. I like the HP a little better because it tells you what devices are connected, but both work well. You can get similar HP ones on ebay for less than $20. I got a pair of Trendnet switches (one POE, one not) from a university surplus auction for very...

My father was an elementary school principal in Los Angeles at several black schools in the 1970s. There was plenty of this stuff back then. Not from the staff or parents, whom he generally liked, but from the 'community organizers. ' Plenty of racism to go around.

You're welcome. Have fun but don't have too much fun. I don't want anyone's wife to be sore at me because her husband bought a government surplus tugboat.

Www.Publicsurplus.com. Search using the 20 miles (or whatever you can stand to drive) from your zip code. Be patient. Try not to get addicted. Governments and universities dump all kinds of equipment, and sometimes it is dirt cheap.

I bought 4 hp elitedesk 800 g2 i5-6500 computers at a county auction for $10 each. 8gb ddr4, a 500gb hdd, and I added a small ssd to each. I was going to use them just to feed live monitors, but I loaded Blue Iris on one, and it runs really well. No AI stuff, but 9 cameras, no problem.

I'm happy I just had the roof redone on the house in Merida. We'll probably get the same storm. Love the old colonial architecture in your photo.

And he wants to bring all the great things he's done for California to the rest of the country.

Angle grinders are so useful, but you sure can whack your fingers off before you know what hit you. I have less trepidation about grinding tools --which can hit and scratch you, but probably won't cut you--, than I do cutting things. I sometimes watch boatbuilding videos by a guy called Lou...
