We have Wyse cameras, some battery wireless, some 120 VAC. The one at the back door had a bug fall in love with it. Bug crawled all over it for about a week, crossing the lense and giving us false alarms. The wireless ones, set on fence posts, often have birds land on them, and you can see their tail feathers swishing around. The doorbell camera gets feral cats, birds, spider webs, dust fairies, mist, and even deer sometimes walk up the steps. And of course, Amazon and USPS deliveries.
