Here’s a nice wireless camera that you can set by voice to monitor a specific area of your home. It has infrared LEDs so you can see images in both day or night.
The Wyze Cam Pan 1080p has a two-way audio so you can speak to your little best friend when you’re not there. Also, the motion detector works well to see their activity as they move about different rooms. Sometimes the camera dies out in a matter of months if left on continually.
