The function of a battery-powered Wyze Cam may need to be different than the powered ones. I currently have 3 Wyze Cams and 2 Pan Cams in my house. I also have several Blink cams that are battery-powered. I have 5 outdoor and 2 indoor. They do not stream constantly. Instead they detect motion, which triggers recording. You can also view the Blink cameras in real time stream, but that is for short periods of time. It asks after 20-30 seconds if you want to continue to watch. That way the battery lasts longer. They say up to 2 years. I haven’t had them that long yet. If you watch the real time view a lot or it is triggered much more frequently, that will run the battery down quicker. I have them for security, whereas I use the Wyze Cams to keep an eye on my dogs. I have the Pan cams pointed out windows to keep an eye on my front & back yards. I just really like the battery powered cams, because I can place them anywhere and move them easily.
