I bought a webcam with temp and audio ( Wansview $74 on Amazon). It needs a wireless connection which is not always good at campgrounds and nonexistent while dry-camping. I purchased a wi-fi repeater so while at campgrounds, I use the camp's wi-fi. When there is no wi-fi, I leave one mobile phone home and use its hotspot to connect the device. It's nice to know our fur babies are comfortable while we are away. The Wansview webcam was a little tricky at first to set up (directions are horrible) but by reading the reviews on Amazon, I found out there is a QR code at the bottom of the device I can scan and it sets everything up in seconds. I can hear if the air is running and know the temp of the interior. I can see them roam around in the living room area and I can talk to them if need be. Now if I can only train them to answer, it would be great!!!
