Wired Stick Up Cam Low Battery Notifications

A few days ago, I moved a wired stick up camera from my patio to my backyard, attaching to my gutter with a mount. Soon after, I got an email notification saying the battery was low and this morning the app said live view was disabled because of a low battery. I'm still using the same power adapter and as far as I know, the electrical outlet outside works. I called and the agent insisted there was an internal battery but I cannot find one. It did not come with a battery nor did I buy one separately. I never got low battery notifications until I moved it. The app doesn't show any battery status on the camera other the warning about live view being disabled because of the alleged non-existent low battery.The camera is under warranty and I'm getting sent another one, but I'm wondering if this a widespread issue?
