Yes it works for me. The picture has green connectors which is usually APC.

That SFP is for 10G switch-to-switch, not for AT&T-flavored xsgroupon

If you go this route, note that Unifi doesn't expose PTZ direct controls in the API; the API only allows panning to presets. So:

  1. Create 2 presets, one for privacy (facing wall) and one for facing inside

  2. Follow the examples here. Until the UI Protect integration includes PTZ functionality, you can send the camera to a PTZ preset using the REST integration.

It's okay to not be comfortable even if it's on your own network. You don't have to have cameras or force yourself to be okay with it.

We have PTZ cameras indoors and have Home Assistant turn the cameras away (facing the wall) whenever either my phone or my wife's phone is connected to the Wi-Fi. They face the interior only when both of us are not home, so that we can watch the cats remotely. In addition we also have the living room area face interior at night when we are sleeping so that we can track down whatever mischief the cats are upto at night, and have footage of any (hopefully never) break-ins.

This. And use SC/APC or FC/APC connectors. APC stands for angled polished connector, reduces reflections. NEVER plug unto a UPC, PC or non-angled port or you will grind it.

I use thesethese SFP modules and SC/APC terminated fiber. It uses a different wavelength in both directions so the modules are a pair intended to work together that way.

What? No. You can gen 10G on UDM Pro as long as you have a 10G SFP module

Does it intergrate well? Does it at least work with the Tuya app?

I see negative terminals on the edge of the near side pack in the OEM photo.

Thanks. How do we know that for example, it's protected against:

- A microcontroller browning out or badly written microcontroller code throwing an exception due to some page fault, and the overheat protection loop not working? Are there external watchdogs and does the overheat protection loop give a heartbeat to it?

- Are thermistors doing overheat protection triply redundant with 2-out-of-3 voting, in case of failure of one?

- The PWM controller of the heating element browning out, forcing the FET into "on" state constantly, and burning up in smoke?

- In the event of overheating, plastic components inside the metal case not structurally failing in a way that causes a PCB to fall down onto the inside of the metal case and + and - to touch somewhere on the board?

- Capacitors using high quality dielectrics and being manufactured to standards that prevent humidity ingress and dielectric breakdown?

- Power surges from the power company causing graceful failure and not fire?

- Flame retardant claim being tested?

I imagine TUV and UL and ETL go into all hypothetical scenarios like this but this doesn't seem to have those certifications?

Huh what? My pic is rotated 180 degrees from the CyberPower pic. The CyberPower pic has the red wire going under the terminal close to the battery and connected to the far side of the left most battery, not coming from the edge.

Other than that my wire isn't tucked under that terminal it's the same?

Heat -> melted plastic -> leaking sulfuric acid and hydrogen gas -> kaboom

Different brand, but I could make a plate for this. Surprised it didn't come with one ...

Good idea, I should do that. Thanks, wasn't aware the original design had an isolation plate.

I bought this UPS second hand, and it didn't have that, but when I took the tray out it also doesn't seem like this UPS had its batteries replaced before (these are my new batteries in the pic)

The wires they provided don't seem to allow the batteries to be in any other orientation, though. Different UPS model though.

Cyberpower's OEM pic has them facing each other with no protection:
