I’m looking for a set of security cameras that will cover my home, detached garage and poll barn. Do wired security cameras need to be hooked together, or can they be off on there own and still be controlled as one? Also places like the poll barn are very far from any power supply so how do I get the wire ran to one? It might be close to 50 or 75 feet before the wire would be long enough. Also, do these cameras connect to your phone so you can watch them while as far away as at work? I’ve looked at Eufy cameras but I feel like just buying the cameras isn’t enough. Thanks for any feedback
