A wireless bridge is two radios that look at each other. It carries the network across a driveway, parking lot, or yard when you do not want to trench cable.
Use it for a barn, gate, second building, or a camera that sits too far for a clean cable pull. It is not a substitute for every camera run. Cable is still the first choice inside a building.
Each end needs power and a clear line of sight. Mount them high, aim them, then plug the far end into a small PoE switch or a camera.
