Top highlights

Revolutionary Triple-Lens Bullet-PTZ Camera: A single groundbreaking device that replaces and outperforms separate bullet and PTZ cameras. The upper 4K bullet lens delivers a 130° fixed wide view, while the lower 2K dual-lens PTZ offers 360° smart tracking and zoom.
Bullet-to-PTZ Tracking and Auto-Framing: Once the bullet cam detects a subject, the PTZ camera instantly locks on, tracks, and zooms in to capture details up to 164 ft away. When more subjects enter the frame, it automatically zooms out to ensure they all stay visible.
Powerful Solar-Charging with SolarPlus™: Stay charged year-round with a 5.5W ultra-large solar panel and SolarPlus™ 2.0. Just 1 hour of direct sunlight a day keeps the camera running, and the detachable design makes setup easy and flexible.
