Just plug and play, you can get them in different sizes, just measure the mileage you need. In my case 26ft is fine for everything as I wire my wyze(3) cameras to run on a single power supply. They have a fairly thick shell but need to be replaced after about 5 years as they are white and will not withstand UV in bright sunlight but it will cost more than travel. This setting works for me now. to search and say it's a great solution, overall I say 5 stars. Note: I am only presenting my views based on the current status
