Batteries Draining Fast

[Albiew]

I purchased the original Arlo package with three cameras and a base unit in 2017.  Since then I have been using two cameras outside and one camera inside.  The battery life of the camera currently in the driveway works great.  I replace those batteries every 60-90 days.  It is also furthest from the base station.  The cameras at the front door and inside the house go through batteries within 10-20 days. I have switched placement of the cameras several times with no change in battery life.  Moving the base station does not help.  What are my options?

Also a question back as to how much activity on the different cameras.... more recording mean less battery life.

Also total distance is less importance as to what the signal travels thru.

As to a solution, the inside cameras, can they be put on ac ?
