Review on Covert HD 1080P WiFi Hidden Camera - Smoke Detector Design with 180 Days Standby, Night Vision, Motion Detection, Real-Time View, and Nanny Cam Function by Robert Hunter

Firstly, the camera looks exactly like a smoke detector (I swear I saw a small light blinking, like normal ones). All you have to do is attach them to the wall or ceiling of the room, which already has a smoke detector for security reasons. The very first thing you have to do is charge it for at least 24 hours so that the battery lasts a long time. Depending on where you place it, you can hide the microUSB cable that charges the camera, so you don't have to worry about running out of battery. The stream looks crisp in both the phone app (which is easy to set up) and in night vision. I installed a 64GB microSD card for recording and I think that will be enough for me to use it. It comes with a microSD to USB adapter to download videos to your computer (in .avi format which is a bit dated but works). Very happy with it!
