  • We are not talking about high voltage telephone equipment.

    The switches in telcos are totally different than low voltage Ethernet with sensitive transcivers.

    Grounding differential potential between structures, even just a few feet apart, is often enough to destroy Ethernet transceivers without lightning strikes or surges.

    Notice: I’ve been in IT and telco for over 30 years. I have worked on Nokia telco switching equipment and can 100% tell you that Ethernet transceivers will absolutely be destroyed with much less effort than telco.




  • Attaching to light poles you dont own or have permission to do is a crime in most places.

    If you do have authority to do this somehow, I would use a power tap on the street light photovoltaic sensor. They are a twist lock style connector. They sell pass through options to keep the original sensor. That’s for the power.

    As for the connectivity… If you have permission to do this, you likely have permission to install a omnidirectional WiFi ptmp station and wireless clients (directional) at each camera. Otherwise, just use LTE or fiber. Most municipalities run conduits between each lamp and there may be existing access for fiber. You could also microtrech fiber (since you presumably have permission).

    I’ve done this for municipalities. It’s pretty easy since everything is already in place- which is why I question your intentions here. Anyone who has permission to do this would probably not need to ask how to do it.














  • Yes, this seems to happen more frequent with brands like realtek. All hardware has failure rates, generally speaking more expensive and enterprise gear fails with less frequency, but can still fail. Personally, I don’t enjoy hardware failure, so I invest in stable clean power and great hardware. It may cost more in the overall power budget but is less headache because things just don’t fail as often.
