I have 4 V2 cameras mounted outside . I am using 10, 20 and 25 ft USB extension cords . I have been having issues with 2 of the V2 cameras that when connected outside I could not access the SD card videos and would get sometime no SD card .
I went to replace one of the V2s with a new V3 camera and it was often locking up and I would get the “Getting Video Data 3/3” . I also had issues with the Audio . Every time I would attempt to speak through the camera I would hear nothing but scratchy static and it would lock up and loose the connection .
The V3 would work fine connected to the standard Wyze USB cable and power supply
.
I quickly built a USB breakout box so that I could measure the amperage and voltage at the camera . I found that just 1 V2 or V3 cameras at the end of my 25ft USB extension was causing a significant voltage drop .
Below are some of the worse cases with 2 V2 cameras daisy chained .
See my YouTube video below for complete bench testing .
