Don't but the outside cams with the base station and Sim cards. Can review the days activities unless you pay into the cam plus feature. Only works if you set up motion for certain areas, but only includes what was in your set up area. Had a car stolen in the street area we took off motion because they weren't in our actual driveway (so our battery charge lasted more than 5 days) and couldn't help the neighbors. Stick to the the cam3 and drill holes everywhere in your house. Get Ring or others
