I have been a host for a year and a half and have a security camera on the front driveway which is disclosed on my listing and allows me to monitor when people come and go. Last winter I had issues with snow and ice buildup in the back yard between the back door and hot tub. This year I plan to buy heated mats to melt the snow between the two. The nice thing is they can be controlled remotely so if there is buildup I can melt the snow even if I am hundreds of miles away. This brings up my problem - I would like to put a security camera in the back to see when the snow is building up and activate the mats. However, I don't want to see guests when they are using the hot tub, or worse have them think I am spying on them. I really only want a camera there to watch the snow buildup and melt it to make it safer. I could just monitor the weather and turn it on then but sometimes snow falls from the roof onto the path and needs melting. Plus even during a storm I would not know when the mats have cleared all the snow. Does anyone have any recomendations on how I could monitor this area without freaking out guests?
