Wired together or on their own

Which way is the best to wire the cams would it be together or would it be better if they were on the own cord and supply?

Welcome to the Wyze community @pupastro9196!
I would suggest that you only daisy-chain the cameras if they are close enough to do it with the included cable. If you need a longer cord to connect cameras, your better off to power them separately. Make sure to use the included power supply to power the cameras and use the Wyze Cam Pan power supply if your daisy-chaining that.
I would suggest not daisy-chaining the V3s because of power limits, but it will work most of the time.
