Ring. I have them all around my house, one on solar, rest are battery. Charge lasts a few months. Get alerts on your phone. Easy to save videos you have to have. I don’t remember what I paid per camera, but I thought it was insignificant compared to troubles caused by not having them and for what they bring to the table. Been using them for three years now. The solar one has never needed a battery in that time. I keep one spare to rotate in the rest. I have the doorbell too and one in the backyard is hardwired with a motion flood.
