I have Ring Stick up Cams around the house. Battery powered, but get 6-8 weeks out of a charge depending on movement sensing... all work up to the cloud. Excellent quality image, including night vision. Not the cheapest solution at £60 a camera, but so simple and hassle free to install. Battery re-charge can be a pain, but climbing a ladder once every couple of months to bring the battery down to charge is a small price to pay for no wiring!

I have a couple of reolink, had them for Years, easy to set up, WIFI, no problem, works with your phone also "it needs some intelligence to undestand you may not have enough"

I spent allot of time looking at wireless, and eventually ended up with wired Hikvision Darkfighters which I am very happy with the night time detail is great!

I will be be watching this closely, as wouldn't mind a few more in non wired locations. Sold - Bell a 2015 MY16 Loire Blue Autobiography 4.4 SDV8
