    Mailbox alarm

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

    HP EliteDesk 800 G4 SFF Intel Core i7 8th Gen

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

    Mailbox alarm

    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.

    Any 12V AC powered IR illuminators out there?

    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.

    Has anyone set up a solar street light?

    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...

    Any 12V AC powered IR illuminators out there?

    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.

    Mailbox alarm

    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...

    never again Dahua! Support form "send" button defect, no answer with email

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

    Which Computer Do I Buy To Run Blue Iris On? What Do You Use?

    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...

    School Thread: Lets stay educated and aware!

    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.

    Which Computer Do I Buy To Run Blue Iris On? What Do You Use?

    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.

    Which Computer Do I Buy To Run Blue Iris On? What Do You Use?

    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.

    Which Computer Do I Buy To Run Blue Iris On? What Do You Use?

    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.

    Storm rolling in

    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.

    POE Trigger/Switch for Mailbox Cameras on BI?

    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...

    POE Trigger/Switch for Mailbox Cameras on BI?

    I'm a "farmer welder" but I think anything that isn't stainless or cast iron is weldable with normal welding wire. Get a spare angle grinder nut, maybe drill a hole to let the shaft go all the way through, and set the ball on the nut so it self centers, then tack. I wonder what uses 3" ball...

    You might try VM eye vMEye - Apps on Google Play. It is the app that the sellers of my ebay board cameras recommended. It will tell you the basic info about the stream, if what you have is a VM format camera. I'm always suspicious that this kind of software is spyware, so caveat emptor.

    I just checked the BI settings for the second one of these I had handy, and it took the same settings. I know I have had this one running with an rtsp stream, but I can't get it to work tonight. Maybe tomorrow when I'm fresh.
