A:AnswerYes you can get the one that plugs in to an outlet that will record always or an outdoor one that uses a rechargeable battery that will only record when motion is detected
A:AnswerThese all run off of Wi-Fi. What you need is internet connection, and an outlet to plug it in. I believe I read that it could work without it being plugged in but I choose to keep them all plugged in. I don't have to get up to answer the door or speak to anyone as I can do it straight through my cell phone.
