How many cameras make a 360-degree view?
Most vehicle surround-view systems use several cameras placed at the front, rear, and sides. Their fields overlap so software can build a view around the vehicle.

Guide
How does a 360 car camera work? Cameras around the vehicle capture overlapping wide-angle views, and software corrects distortion and stitches them into a simulated overhead image. It is a parking aid, not a transparent view through the car.
Most vehicle surround-view systems use several cameras placed at the front, rear, and sides. Their fields overlap so software can build a view around the vehicle.
The processor corrects wide-angle distortion, maps each feed to a virtual ground plane, and blends boundaries. The result looks overhead, although no camera is actually floating above the roof.
Software needs precise camera position and lens geometry. Body repairs, mirror replacement, suspension changes, or camera movement can misalign seams and distance cues, so follow the vehicle maker's calibration procedure.
A stitched image can contain blind areas, stretched objects, delayed frames, dirt-obscured zones, and discontinuities where feeds meet. Always use mirrors, direct observation, and parking sensors as instructed.
A panoramic dash cam may use an ultra-wide lens or several recording channels, but it does not necessarily create the calibrated overhead parking image supplied by a vehicle surround-view system.
Common questions
No. Software combines exterior camera feeds and fills their geometry into an overhead-style view.
Some vehicles record selected feeds, while others use them only for live parking assistance. Capabilities depend on the exact vehicle and equipment.
Stitching boundaries and lens correction can stretch or split objects, especially when they are close to the vehicle or between cameras.
Aftermarket systems exist, but correct camera placement, wiring, weather sealing, display integration, and calibration make installation complex.
