The hidden nanny camera that resembles fire and carbon monoxide detectors is as described on the product description page https://www.amazon.com/MEAUOTOU-Detector-Wireless-Security-Monitor/dp/B01MYZN0ZT. This was fairly easy to set up and download the needed program on my phone. Since I am gifting this to my niece for her upcoming bundle, I didn’t check the capabilities of saving video. I set it up in my living room and snapped a few shots when I logged in at different times. These little nanny cams are hard to detect if you are using to spy on someone. If you are just checking in on the baby, kids in the playroom or watching a busy area this camera is good. If you want to have up all the time, you will be doing a lot to putting up and taking down to charge, unless you got a really long USB cord and always had plugged in charging. So its great for short term use and giving you peace of mind in a questionable situation.
