12V DC Power Drop / Max Cable Distance Chart
The below DC voltage drop cable distance chart works as follows. The left column notes the amount of power that the device you are powering requires (red text). The “mA” after the number stands for milli-amps. For example, say you are using a CCTV camera that requires max 300mA. Using 18 gauge power cable, you can run your cable up to 289 feet.

Some Arlo Cameras, Including Popular VMC3030 and VMC4030, Will Be Moved to EOL
Starting January 1, 2023, Arlo is implementing an EOL policy for its products and services, with the Generation 3 (VMC3030) and Pro (VMC4030) cameras being affected on April 1, 2023. These cameras were released in 2014 and 2016, respectively. The EOL of the Generation 3 (VMC3030) and Pro (VMC4030) cameras means that certain features of, and support for, these cameras will become unavailable, including 7-day cloud storage, firmware updates, and email notifications.
