Each phone came with a charger, and they run "IP Webcam", a free app on the Play Store. I have them semi-hidden in bookcases and other out-of-the-way locations so they're not obvious. I usually just use IP Cam Viewer Basic, another free Android app, to check on the pets when away from home. My home automation hub (Vera) works fine with the phones as IP cams as well.
