After much searching and reading I decided on a NVR PoE system. Many brands have many complaints about support.
Currently looking at Hikvision EKI-Q82T26 and Night Owl
Design is for all outdoor cameras. Pic attached.
Cat 6 from house to barn to carry data of 3 cameras 300' from router to wireless access point Not sure which cameras to use.
Would like to add 1 PTZ to barn.
Should I use Cat 6 for cameras? Camera runs are less than 70' or less.
All input appreciated.
