The Paw Patrol Chase HD WIFI camera has a lot of good things going for it. Number one is the cost for what you get. I have security cameras that cost 4 times what this camera costs and some functions of this Paw Patrol camera are superior to them. To operate this camera you must install an app to your smart phone. It is very easy using the QR code in the instruction manual. After downloading the app it walks you through setup and connects to your home WIFI. From your smart phone you control the camera and all of its settings. In addition you can download a program to your PC or tablet (Apple operating system not supported) that allows you to view live, record live or take a current picture with this camera. Features include: 1080P HD picture, IR night vision, 120 degree wide angle view, single or 2 way audio, motion detection with alarm and text message notifications. You can save videos and pictures to your cloud account with a micro SD card. If you do not want to save any recordings and just watch live view you do not need an SD card. The alarm is a LOUD police siren that comes directly from the unit itself. This loud alarm is great for any grandparent like me for when the grandkids are visiting. I close off the back bedroom where they are not supposed to be and if one of them opens the door to that room the alarm sounds. This camera works for monitoring a baby's room, a child's play room, the outside door to the swimming pool or just keeping tabs on the nanny. When the grandkids are not visiting I have this camera set up in the vestibule focused on the front door. If any intruder comes in the alarm sounds and gives me those precious seconds to re-act. The only negative thing that I have to say is that the instruction manual could be better. I have used this camera for 3 weeks and I am still learning what it can do by trial and error. Every time I find a new feature I am delighted and wish that it would have been explained in the instructions.
