which is the best one you recommend for a small life style farm. Have 4g no WiFi, Ideally one that moves around so I would only need one camera on the house ?

the 4G ptz (the one in the video is actually pretty good) for what you need. You can rotate the lense from your phone and it comes with upgraded 6 batteries and big 8w panel. We do have the bullet fix camera which is abit cheaper too (but those are fixed and they have 4 batteries in them- also alot smaller panel )
