Depends on what you shoot. Professional (SJ30, SJ6 Ultra, SJ20) for 4K–8K, dual lenses, and the best stabilization. Pocket (C100 Pro, S10, C110 Plus) for a mini body on a magnetic mount—POV, cycling, everyday carry. Budget the SJ4000 series for daylight recording at the lowest price. Start with the line that matches how you mount the camera, not the resolution number.
Professional cameras are the largest and most capable—higher resolution, dual lenses, and the strongest stabilization. Pocket cameras are built around size and mounting: magnetic, wearable, under 80 g, and designed for POV shooting. Budget cameras (SJ4000 series) cover the essentials—4K/30 fps, 16 MP photos, and 30 m waterproofing with the case. Pick Professional for quality, Pocket for convenience, and Budget for price.
An action camera wins for normal framing, sharper detail and simpler editing; a 360 camera wins when you want to reframe the shot afterwards or capture everything around you in one take. If you shoot sports, travel or POV as fixed shots, stay with an action camera. Choose 360 only if you genuinely need to re-aim in post.
4K is enough for most people—it is the resolution every phone, TV, and editor handles natively, and the budget line already records it. Choose 5K or 8K if you crop or zoom in post-production, or shoot for large screens. Higher resolution also means larger files and more storage, so only go up when you have a reason.
Yes to both on most models. Connect over USB and the camera works as a webcam for meetings, classes and calls. Car Mode turns it into a compact in-car recorder that starts recording on power-up and manages clips with loop recording — the SJ4000 line supports both.
