I purchased this to keep an eye on a disabled family member who is on a different floor and wow am I impressed. You just download the Tend app for free on your phone or in my case Ipad and it syncs in minutes. The image is perfectly clear in light or in the dark. You can talke through it if you want. You can set it up to give you movement alerts, which would be great if yiu have kids that don’t like to stay in bed or have na elderly parent that has dementia. It surprised me that it has a very wide angle lense. Love that it just looks like a toy on a shelf. You won’t be disappointed this is just a great little monitor that also has 24 hour free cloud storage if you set it up for movement.
