If you own an APC Back-UPS 1500 UPS possible model number BN1500M2 and have experienced a failure with Error F04 and possibly Error F02 with the sound of arcing coming from the unit the problem may be the transformer. It appears the units are shipped with transformers that have copper coated aluminum wire and the connections have failed or broke free. If you have unit and it is in some critical role you may want to take it out of service.
see this video for details.
Security First (which seems to be no more) 5005 cameras use RJ11 6 pin connectors. Their pinouts are as shown in this diagram.
The wires in the connector and 100 foot cable are Red white black black. pin 5 may be yellow in the 100 foot cable. the colors in the diagram are from the camera.
the wires internally to the camera are Red white black yellow.
Information I can find states the red wire can accept 12-15vdc which means that it probably has a voltage regulator in side and is compensating for the massive voltage drop through 100 feet of very small wire.
I have no other information than what is presented here.
Sainlogic WS0835 weather station manual
This is the manual (including calibration) for the above weather station. This version does not have a wifi connection. I do not know if that matters for the calibration.

Several years ago I was put on omeprazole for acid reflux at night. The doctor never indicated any concerns for long term use of it, As usual I read the side effect.
After an unknown amount of time I began to develop a feeling in my feet like they were always dry. I didn't pay much attention to it because I could feel heat, cold, and touch just fine.
Eventually I went to the a neurologist after seeing a podiatrist over an unrelated matter.
It seems that I had neuropathy in my feet. How I got it was a mystery. After some testing it was determined that A. it was not genetic, B. it was not diabetes, and C it was a vitamin B12 deficiency.
How did I get a B12 deficiency? I eat foods with lots of B12.
I did some research on it and found that buried deep in the drug manufacturers website was that omeprazole should not be taken for more than 2 months. It did not say why. Well the reason is that omeprazole interferes with the bodies ability to absorb certain vitamins.
I am now on vitamin B6, B12, and folic acid supplements but I could have lost the use of my hands if this had gone too far.
I smell a class action lawsuit.
