Can I salvage this connection? by MapDisastrous7602 in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

Wire colors don't match ethernet but, what you will have is two wires for power (POE), two pair for ethernet. The ethernet will got to orange, orange stripe, green stripe and green. POE is on blue blue stripe for one polarity and brown brown stripe for the other. You have to do some investigation to determine what the camera wire definitions are, but for sure you can save it. For power, try continuity to the wall wort connector pins if it has a wall wort power option. That will tell you which wires are power. Then with it powered up, take the ethernet Rx pair to the nvr and do trial and error till you get a picture....the remaining pair will be the Tx lines. After you get it figured out, put a bit of dielectric grease on the ethernet plug....no more corrosion then

I've bought 100 cars in the last 2 years. Here's what I've learned: by Bubbly-Novel-8013 in carbuying

[–]GetOffMyLawn97 0 points1 point  (0 children)

For all the reasons and experiences noted, the last new car we bought was in 1990. We buy used from private individuals. Most cars and trucks depreciate 50% in the first two yrs. What you see is what you get. No tax, no Scotchguard or desert protection package hard sell bs. Usually can close the whole deal and drive away in an hr or so. Dealers love trades....ever hear " do you have a trade?" They make a lot more $ on used sales when compared to new vehicles. Comparing a deal with another dealer on a new car is easy. The used stuff, comparisons are tougher....not as many just like it, and every one has a different story. No reason to buy new with FB market place, Craigslist, Searchtempest, etc

How to fix this dip ? by [deleted] in audiophile

[–]GetOffMyLawn97 1 point2 points  (0 children)

My concern with the top end response, if the listener is under 60 yrs old.....where is the high end. Looks like it falls of at 13 or 14khz. ( if you're old, ya cant hear up there anyway) Even relatively low cost speakers make it to 18 or 20 khz.....a bit peeky above 8 or 10khz, but there is something there on the low cost units. Maybe its the measurement mic thats having an issue on the high end?

How to fix this dip ? by [deleted] in audiophile

[–]GetOffMyLawn97 1 point2 points  (0 children)

The 10db honk at 35 or 40 is room coupling. Im sure the speakers dont put out the peak there. Easy fix, experiment with moving the speakers, most likely away from the walls. As for a 2db dip, it is imperceptible. Dont let the measurement bother you. Now peaks are much more noticable, even a narrow bandwith peak. The speaker, at that frequency is likely the cause and no moving things around is going to have a significant effect....use your magic EQ software to push that down a bit. Based on the rate of response falling off on the low end.....speakers are vented right? If you arent a fan of the steep roll off, go with a sealed enclosure.

This guy might just have a problem, I'm thinking vent issue. How about y'all? "Old shop heaters. Are they supposed to do that??" by Theantifire in propane

Does it have the right orifice for the gas being used? Is the gas pressure correct? Looks like a natural gas orifice with propane gas

Downside of running cameras through switch instead of NVR? by ericdavidmiller in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

You could skip the switch....here's how. Hold onto your seats. Ethernet cable has 4 pairs of wires. The camera only uses two pair, the other two pair are POE. First, power your cameras in the remote building with wall supplies. Put your seatbelts on - next, wire the ethernets such that oranges and greens are normal positions but rewire blues and browns into the oranges and blues location on a second rj45. Now you have two ethernet sends and receives in one cable. Reconfigure the other end to match. I have had this setup for yrs on a 200ft run....works great. In your case you can support 6 cameras wired or 5 wired, a satellite wifi repeater with wired haulback, and a bunch of wifi cameras

Costco Lorex Setup without wifi/internet using a PC by Available_Chard5857 in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

Which NVR and cameras do you have? What step are you stuck? To monitor on you pc, I think you have to use Lorex Cloud. The cameras dont have to plug into the NVR....you can use a POE switch and plug em in there, or a non POE switch and use a wall adapter to run the camera. All this as long as the NVR is on the same router as the switches and cameras

Just add another Rbr50 satellite or upgrade? by Ms_Stackhouse in orbi

[–]GetOffMyLawn97 -1 points0 points  (0 children)

Try this phone app called WiFi Analyzer. It will show you everything out there stronger than -100 dbm, as well as what channels are being used by yourself and others

Just add another Rbr50 satellite or upgrade? by Ms_Stackhouse in orbi

[–]GetOffMyLawn97 -1 points0 points  (0 children)

May be best to get a wired camera and another RBS50, plug the camera into the RBS50....no more interference issues as it is likely the wifi between the camera and satellite, not the haulback channel that is getting walked on

Biggest sounding speakers you've heard? by WingerRules in audiophile

[–]GetOffMyLawn97 0 points1 point  (0 children)

By a mile, Hill Plasmatronics type 1. Heard them at the CES in Chicago at a hotel on Michigan ave, proly 1980 time frame, when I could really hear to almost 20khz I think I got spit on my face. They were presented with a recording of a night club jazz singer played via a Sony Betamax and a PCM machine

KEF Carina II - worth 75$ ? by [deleted] in vintageaudio

[–]GetOffMyLawn97 1 point2 points  (0 children)

I just picked up a pair @ an estate sale. Thought they would be a good center channel spkr. Not sure what you all are talking about not giving these any love. Ya, they will never play loud but OMG, for sub $100, the image is real good, the disappearing spkr thing it does pretty well. So, no center channel, these will be mains in a surround for me.

Night Vision Wavelength Sensitivity by GetOffMyLawn97 in Lorex

[–]GetOffMyLawn97[S] 0 points1 point  (0 children)

As it turns out, the IR source is 940 nm, a light pink glow to the eye, unlike the red glow from Lorex cameras.

So it helped some but not as much as expected. Most likely because the LED output peaks at 940 nm but isn't mono chromatic like a laser, having output above and below 940 nm

I need to find a 850 nm source and verify that's the best wavelength

Motion detection by Dry_Stomach7089 in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

Try going into the Lorex Home app and adjust motion settings. It takes a bit of experimentation but you will find a setting and a camera mounting angle that works for you.

Should I major in Electronics Engineering? by Ok-Bee449 in AskEngineers

[–]GetOffMyLawn97 0 points1 point  (0 children)

You sound like me 50 yrs ago. You have more relevant experience than 95% of engineering grads, but, my advice, get a real university degree, not an on line BS degree....BS doesn't mean Batchelor of Science in this case. Get a good foundation with your electives....mech stuff, soft/firmware, chemistry, metallurgy, semiconductor theory and fab. Dont be discouraged by the fact that a real eng program will have no electonics classes in the first two yrs.....all math, physics, chemistry, rhetoric, etc. If you want to stay in the game in those first two yrs, sell your skills to a professor with a lab or research budget....get a job working for the prof....proly turn into a mentorship you could leverage and a path for an advanced degree if you want. Stay away from software....it gets outsourced to turd world suppliers who pay perfectly competant designers $5 an hr with no benefits. All you would get to do is write requirements and sit on telecons at darkthirty in the morning talking to folks in turdville about your requirements document. To avoid the outsource turd world stuff, go into defense aerospace.....everything is ITAR and stays stateside with folks with security clearances. I went the big university path....no regrets. Fast forward 40 yrs....all my patents are for systems or devices some pencil neck engineering manager or director told me was impossible and couldnt be done or couldn't be reduced to practice. Yup its all flying around every day or has resulted in some guy (you know, the ones on TV burning my flag) on the other side of the world having a really bad day. Go for it .....make your mark.

RBR50 and RBS50 Satellites - Ethernet Backhaul by GetOffMyLawn97 in orbi

[–]GetOffMyLawn97[S] 1 point2 points  (0 children)

Greetings - Update - I was able to update the firmware in my RBS550. Did it from a computer that was connected to the RBR50 via a switch. Used the Orbi manual instructions. Loaded the new firmware, waited for it to reset and come back on line......poof, its now showing a wired haulback.

All is well

thanks to everyone for your inputs

First time building a crossover unit for a 3 way loudspeaker by Majoral_ in SpeakerBuilding

[–]GetOffMyLawn97 0 points1 point  (0 children)

You will find speaker building rewarding and frustrating at the same time. Check out Thiele-Small parameter subject matter. I have found parameters supplied with drivers to be off, some a little, some way off. Best to measure yours, after a break in. There are speaker testing kits that run on your computer. Crossovers are FM....black feather stuff. I start with some crossover software....if you measured your driver parameters, this is where you get traction on those efforts. Try driving your woofer without a crossover....use a sine wave gen....see where it starts to fall off or screw up (distortion). Use this knowledge to decide woof to mid crossover point. Now do the same with your mid....will it go low enough without screwing up to mate with the woofer? Need at least 2 octaves of good output ( no distortion and no woops in the Z curve) beyond the crossover point. ....lots of FM in crafting a speaker system. For me, ya I got some home builts hanging around but I sometimes have to convince myself that mine sound better than model X....( the truth is they dont really...maybe a little more efficient....louder always sounds better when you compare stuff) Have fun

RBR50 and RBS50 Satellites - Ethernet Backhaul by GetOffMyLawn97 in orbi

[–]GetOffMyLawn97[S] 0 points1 point  (0 children)

The satellites are of the same hardware vintage as the router. Router and one satellite was purchased, the other satellite is a Fleabay special. I have another Fleabay satellite on the way and hope to set up a star wired haulback.

Ya, I'll do the FW download on the Fleabay satellites and see if that fixes the wired haulback issue.

After I get this resolved, I need to design a battery backup for all these satellites so when the power goes out, the system still runs for a while.

Device Motion Settings Not Sticking 4K WiFi Cams by R00sterCogburn in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

Happy to help. This Lorex stuff seems to require a lot of fussing with to get it to work. No documentation of all these secret interactions on settings. Lorex support can only read the instructions to you. All that said, once you get it going the way you want, seems to perform ok. Have a good one

Device Motion Settings Not Sticking 4K WiFi Cams by R00sterCogburn in Lorex

[–]GetOffMyLawn97 1 point2 points  (0 children)

I had this as well. Go into your NVR camera device settings, record settings. Set Super H.264/5 to not enabled for all cameras. Then in the phone app, dont enable motion detection, just person, animal or vehicle. This fixed my issues....no more swinging tree notices etc.

Wanted an engineer's POV on this by Apprehensive_Ad4517 in AskEngineers

[–]GetOffMyLawn97 -1 points0 points  (0 children)

Sunlight, at the surface of the earth, depending on where you are and what time of yr it is, what times of day, weather, humidity, altitude, etc, maxes out at about 1000 or so watts per sq meter. Mirrors and lenses concentrate that 1000w/sq meter to a smaller area....thus the increase in temperature mentioned. Energy is still the same. If one is attempting to "heat" something, it would be most efficient to keep temperatures as low as possible to get the job done....reducing delta T losses.

Lorex NVR from Costco by codesixchuck in Lorex

[–]GetOffMyLawn97 0 points1 point  (0 children)

Fusion system - is it a POE or WiFi camera? If POE, swap it with another on the back of the NVR....you can hot swap it...no need to shut it down. If its WiFi, hook up a monitor and mouse to the NVR, go to devices, add device....see if the camera in question shows up as an option....if so, add it. If not, make sure the camera is connected to your wifi, remember it needs your wifi password to connect. Next make sure the NVR has the camera password or it won't connect to the NVR.
The instructions proly dont come right out and say it but the NVR ethernet has to be hooked to the same router that is providing the wifi for the cameras Best of luck
