The technical starting position
A barn, shed or gate building sometimes lies outside the reach of a neat cable route. Trees, other buildings, weather and power supply then determine the feasibility of wireless.
A network bridge can bring camera footage to another building, but the environment determines whether this becomes a stable route.

A barn, shed or gate building sometimes lies outside the reach of a neat cable route. Trees, other buildings, weather and power supply then determine the feasibility of wireless.
Check visibility, distance, mounting points, power supply, expected image load and what happens in bad weather. Also investigate whether digging or fiber optic is ultimately more sustainable.
Choose a bridge with suitable antenna and security, or make a wired connection when reliability and expansion are more important. Do not mount outdoor equipment without a suitable mounting system on a wall.
Test live image, recording and stability at different times. Document setup, equipment and a recovery route if the connection is later disturbed.
Planting and sightlines can strongly influence the connection.
Not when maintenance, stability and future expansion are taken into account.
