I absolutely love them! I feel so much safer as do my neighbors. The picture quality is outstanding. The sound quality is outstanding. All features are outstanding. This is my first camera system and it came as a referral of a coworker. You only need to have WiFi, it is all completely wireless. I had to charge the cameras a week later but I do have a lot of critter activity, plus the mailman every day. Totally worth climbing the ladder for. However, it took me a minute to activate because it wasn't clear at first that I needed to press and hold the tiny black button on the battery housing thingy for each camera. Then voila! Highly recommend!
