    Not getting all the triggers...

    Understood. I will give that a try... Could I go zone C all filled in and the make A and B the zones for direction? The MQTT message goes all over the place.

    Not getting all the triggers...

    So I noticed that my camera is not triggering on every car that goes by. I changed the trigger to be super sensitive. The car at the end went by while I was doing full video record. No trigger. I tried edge vector and simple triggering. I just switched to B&W triggering. I seem to be...

    IPC-HFW5241E-Z12E dialed in for night

    Ok- I found another setting-- if you make it full time then you can select color and B&W. Thanks.... Daytime now forces color--

    IPC-HFW5241E-Z12E dialed in for night

    I can't even change my "Day and Night" mode to B&W. It is set to auto and I cannot change it. I tried a bunch of settings... I about about 150 to 180 feet I think. I have IR spotlight on the spot... I think I am going to just change my day/night mode to happen like 30 minutes before sunrise...

    IPC-HFW5241E-Z12E dialed in for night

    Do you use Blue Iris? I shut off the PTZ/controls to the camera from Blue Iris to have one less variable there. All the modes on the camera are set to manual focus. I set the camera to continually record. I'll see if and when the focus gets out of whack... Not interested in running multiple...

    IPC-HFW5241E-Z12E dialed in for night

    Just dialed in my settings for night time once again. Pretty damn happy with these ones.... Figured I'd share for anyone with a setup close to mine. The IPC-HFW5241E-Z12E. I am noticing my camera occasionally goes out of focus. I have it on manual. I set it to night and day using the http...

    Is reddit right about copper cables between buildings?

    True, but my assumption was he was trying to go building to building here where each had their own power/ground. POE doesn't necessarily apply in this case... My access point is currently uses 24VDC injector. https://store.ui.com/us/en/products/poe-24 With the amount of pine needles that...

    Is reddit right about copper cables between buildings?

    Low voltage only needs to go down 6 inches. I have a conduit out to our generator-- and then I used a trencher to go another 100 feet to an outdoor wifi access point... Through the woods so it isn't like equipment runs over it. I'd love to see the SNR with those things being 10 feet apart...

    Is reddit right about copper cables between buildings?

    On the receive side obviously? Would that then require that the transmitter be isolated? I feel like my day is about to be wasted rereading the IEEE PoE specs.........

    Is reddit right about copper cables between buildings?

    The last time I looked at this, this is usually done using isolated DC to DC converters which have the transformer embedded right into the substrate.. So they are still magnetically coupled..... just within a single part.... The overall point being the user (and/or installer) doesn't need...

    Is reddit right about copper cables between buildings?

    Much appreciated since I had a few glasses of wine and didn't have my glasses on when I typed it out on my phone. I think the confusion is that all the "grounding" on the sides of the transformers is done at each house side is done in the equipment itself per the spec. If you tried to run a...

    Is reddit right about copper cables between buildings?

    Sorry. You don’t know what you are talking about. Grounding is not an issue at all because Ethernet over cat5/cat6 is magnetically coupled. only in shielded cables does this question ever come up. the ethernet spec is designed so that users can connect without worrying about such...

    Is reddit right about copper cables between buildings?

    Lightning mitigation is never a bad idea. Neither is using optical. Ethernet wires between building never “touch” so the buildings are isolated. We routinely run Ethernet from hangers to planes and they have a ground and a floating ground. All is good. If you are designing an Ethernet...

    Is reddit right about copper cables between buildings?

    Yes. ASIC designer. I posted the grounding concerns if one chosen to use shielded wire. I recommend ubiquiti surge protectors at each end. I don’t have time to look for the Canadian code. Don’t care if you take my advice. The cable modem systems connect to all houses and don’t use optics...

    Is reddit right about copper cables between buildings?

    It is perfectly sound advice. It is also sound to use optics... both decouple the buildings.

    Is reddit right about copper cables between buildings?

    Ethernet is magnetically coupled. There is no ground wire in it. Thus, there are no grounding issues. Often, you use shielded wire where you ground the jacket... You need to look out for ground loops in that case... Someone posted this a while back...

    Is reddit right about copper cables between buildings?

    Lightning. That bright light in the sky that occasionally hits the ground. Creates magnetic fields.... Nothing wrong with optically coupling either- but not required...

    Is reddit right about copper cables between buildings?

    Electrical engineer here. You can run copper..... the grounding won't be an issue. I highly suggest using ubiquity surge protectors at each end of the wire. I have several outdoor runs on my own property... lightning is your enemy...

    Very Loud Explosion Sound

    What it hot and humid out? Sounded like maybe lightning..... You should be able to find a lightning strike detector for you area online somewhere.
