What to look for

Not all 4K cameras are equal. Resolution is only part of the picture. The sensor size, aperture and night vision technology matter as much as megapixel count. The eufyCam S3 Pro with its F1.0 aperture captures far better low-light footage than a basic 4K sensor.

Frame rate matters for detail. Most solar and battery 4K cameras run at 15fps to preserve power. Wired cameras like the Tapo C560WS can run 24/7. If you need smooth footage of fast movement, a wired camera has the advantage.

Dual 4K is rare. The Tapo C675D is the only camera here with genuine 4K on both lenses simultaneously. Most dual-lens cameras use 4K on the wide lens and 2K or lower on the telephoto.

Zoom quality varies. The Tapo C675D offers 18× hybrid zoom at 4K. The eufyCam S4 offers 8× hybrid zoom but its PTZ cameras are 2K. Check whether the zoom is optical or digital — optical preserves image quality far better.
